Power and Batteries - The Mundane Necessity

The thought that "batteries" may make a thrilling blog post, that would keep any reader glued to these mere pixels, is one that has not even vaguely crossed my mind. Yet, the way in which I power my sound kit actually does make a significant difference to how I work - as when I don't have to worry about power issues, I can concentrate more on the sound. Any recordist knows how frustrating it can be when the directors comm's go down during a take, or worse when a radio mic battery fails. Nothing you can do can completely prevent very occasional failures, but a well considered approach can greatly reduce the chances.

Reduce / Reuse / Recycle

I made the decision a number of years ago to only use rechargeable batteries whenever possible, as it made sense in two fundamental ways: 1. It's cheaper and 2. It's far better for the planet (but for those of who don't hold with this "hippy shit green ethos", please see point 1). The only downside that I can see is that it does involve a little bit more work and management on my behalf, as the rechargeables that I use do require a small amount of maintenance to get the best from them, and they have to be charged after use: but at the end of the day, I really don't see it as any additional hassle to be honest.

I have four different portable power sources that work together to give me various options to suit how I'm working: Sound Cart Battery (not discussed here), NP1 (Style) for the Handbag, PP3s (Radio Mic Transmitters) and AA's (Comms and Timecode).

Electric Handbag

I've been amazingly impressed with the Hawkwoods kit: it's robust and it's reliable. Admittedly, the initial outlay is expensive - but I don't regret it and you get what you pay for in my experience. I have four of the NP65 Lithium Polymer Batteries, which I judged to give me the best power / pound ratio. With my Sound Devices 788 and my 2 Micron DDH3 racks, I find I can use up to three on a long day with lots of channels - and I have the forth battery as a "spare". With these, I use the NPU-SQN4S regulated shoe, that can step down the output voltage to 9V if necessary. As for the charger - the 4 way MR4 was the only way to go. All four batteries can be put in at night, and all four will be charged by the morning. Not only that though, this charger can be used in a car from the lighter socket, and power a 4 pin XLR cart from the mains if necessary. Incredibly versatile.

AA and PP3

On a drama, I can easily eat my way through 20 AA on a normal day, for Timecode Boxes, Comms for directors / script supervisors / Execs / AD's, so having a reliable source of rechargable AA batteries is a absolute must. I've always been a fan of the Ansmann AA batteries that come with a 2 year guarantee, offering up to 2850 mAh, and always finding them to last through a days work. The slight downside is that as they get older, they don't hold their charge so well in storage. So in the past 6 months I've swapped over to the low self discharge type, the maxE 2500mAh. These style of batteries don't loose their charge (in storage) anywhere near as quickly as the conventional Ansmanns - and they are bloody brilliant. On the last long running drama, we only had to replace one set of comms batteries, and that was right at the end of an extended day that over - ran! The Ansmann Energy 16 charger, is great too - 12 AA batteries in one hit - and it conditions them as well.

I also have to mention my supplier - Tantronics. Fantastic support and customer service - giving 3 year guarantee on Ansman and Maha AA battery chargers.

Up until about 5 or 6 years ago, rechargable PP3 Batteries in radio mics was just not feasible because of the low power capacity of the rechargeable version. It was only when the iPowerUS batteries appeared that it be came a viable alternative to the high power PP3's.  Although the initial investment seems high at around £12 for a PP3, these batteries have a long life - and are lasting more than 5 hours in my Micron Explorer radio transmitters. The best UK source for these that I've found are Richmond Film Services.

As I said, hardly a thrilling blog topic. But something I wish I'd known 5 years ago.

Making a Living and Low / No Budget Productions.

It's always an interesting decision as to whether to take on a "low/no budget" job, especially for those coming new to the film and TV industry. I think the most important thing to remember - whether you are 'working' for old friends or new ones - is to remember your worth.

When being asked to work for free - (which let's be blunt - is in fact illegal, as every job has to pay the national minimum wage) - it's worthwhile remembering that you're not just working for "no money", but you are in fact supporting the production by providing them with your skills and experience. So you are funding the production.

When starting out, this equation may seem to be simple enough, as you may feel that a lack of experience means that you can offer a production very little; but this is rarely the case - once again, value your worth - what are you bringing to that production: Yourself? Your (rather expensive) education? Your car (as you've probably only been offered petrol expenses) ? Your Mobile phone? Your kit ? (And are they going to insure it?)

But what is on the other side of that equation: what are you going to get from the production? It is this answer that essentially tells you whether to take the job or not. Even when being paid, there may be certain things that attract you to / or away from a job (the script, the crew, the technical requirements, the proximity of the shoot etc) meaning that you'll work for less / more money.  And, (in my opinion at least), the same thinking can apply to a low budget production - try and quantify what you are going to get from it: working with a new piece of kit / working with an HOD who is already established in the industry / wanting to try a new technical set up (new radio microphones / new hard disk recorder / new firmware upgrade) / testing out a new crew relationship.

But - and it's a fairly big but - be very aware that experience that you may build up on low budget productions will be (prepare for a sweeping statement here) "low budget" experience; and not necessarily be transferrable to fully paid work. It's very much dependent upon the productions involved, but, for example, with a "no-wages" production there is no financial penalty of working over-time; so it's often taken for granted that crew will work beyond their agreed hours. Which is the ultimate irony / insult, as now you're giving your time at an overtime rate for free.

I can remember when being asked to work for nothing on a short film many years ago, I politely replied I would happily work for free if the director would come and do an equivalent hours manual labouring for me (building the house). After a stunned silence, the conversation quickly ended with me not doing the short. With hindsight, I wished the conversation had continued something like this: "But I don't know how to put up plaster board", "Good point", I  would reply " I know how to do sound, so perhaps you should come and do more than the equivalent number of hours, to offset the skills difference."

Getting into the industry can be quite hard - the classic unbreakable cycle of unable to get a job without experience, but how do you get the experience without a job. There are apprenticeships out there, and trainee and entry level runner jobs, that do allow ways into the industry whilst earning a living. Working on a low budget productions may offer a way out of this cycle, but remember though, this is a job (albeit a very enjoyable one), and jobs are there to make us a living.

Lancaster Bomber

Last weekend presented a very entertaining shoot - all aboard a Lancaster Bomber. And it was not just the location that proved to be tricky ...

Lancaster - Photo's courtesy Chris Hainstock

This short project came about through my connections with Lincoln University, and it sounded like such an interesting shoot that was going to be providing a number of 'interesting' challenges, that I climbed aboard quite quickly. I must add though...we never left the ground!

Red Epic

The first factor was that because of the cramped nature of the majority of the shoot, the team had decided to work with the Red Epic. However great the images may look, the fan noise of this camera is a real problem. The minimum fan setting when 'turning over' is 25%, but in a small space - such as the inside of an aircraft - this is still very noticeable. However, it is not this that is the main problem; the problem is that when 'not turning over' the sound of the camera fan is akin to a kettle boiling, and it makes it completely impossible to listen out for noise on set - such as lights singing / ballast hums / squeaks - the DOP even made the comment one of 'I'm sorry, say that again, I can't hear you over the noise of the camera'. So the first take, can feel a bit like the rehearsal. Also the DOP and director, told me of the day's filming prior to my arrival, where they had been filming a long and intense interview with a war veteran who flew in the Lancaster's. During one of the long takes, the Red kicked the internal fan on and ruined the take.

I kept sound separate from the camera, but did sync timecode via an ambient lockit box - although we never did manage to achieve genlock - even after numerous phone calls and emails to the camera hire company, RFS and everyone else we could think of. So, we never resolved whether it was down to a software setting in the (somewhat) impenetrable menu system or a simple cable fault.

Sync Sound

In the bomber, every actor is going to be wearing a flight mask, so there is actually no lip sync as such - but that did not mean I was not going to get the best location sound that I could. And also it was key that every actor was mic'd up, as the director and actors (and various other members of the team) had to be able to communicate with each other so as to get the best performance possible on camera.

Rigging Radio Mics' and comms.

Each actor had a wireless cos 11 hidden with the peak of the flying cap, and also a wireless comms ear piece in one of their ears - this meant that there could be full communication to and from each actor. This was key, as the space was so cramped onboard the lancaster, it was vital that the minimum number of crew were aboard / blocking the single (and somewhat trecherous) access route. 

In each filming location - cockpit (Skipper and Flight Engineer), bomb aimer, Mid-upper gunner, wireless op, Navigator and rear gunner - I also placed a schoeps ccm41 to get some air into each of the radio mics. The huge advantages with this mic in this situation was its small size, and its wide angle of acceptance.

As it was only possible to shoot one member of the cast on camera at a time - due to space constraints, so the out of vision members of the flight crew were located on the place, near a playback speaker and boom mic (MKH50), and each scene was played out in full whenever possible. Also, by recording the MKH50 (as well as routing to the on-camera actor's ear pieces), I recorded a completely clean version of the dialogue tracks without the masks in place for audio post production to play with.

Working in the Dark - Filming over night to get the blackout effect.

Non-Sync Sound

Original Lancaster Radio System

As we were setting up the cameras on Just Jane, one of the curators of the museum offered the director and I the chance to hear what the headsets would have really sounded like, as they had refurbished two full head sets with the original communications systems. It was such an amazing a distinctive sound - and it seemed too good an opportunity to miss - so whenever the camera team were setting up, one of the sound team would take an actor, and run though their entire dialogue, but recording the sound through the original head sets - here's a very brief example of my first test recording.

Huge thanks to Lindsay Smith from Lincoln university, who did a stirling job of helping me out on this job. And follow information about the lancaster bomber film on twitter @lancastermovie

One Meter to rule them all...

Ever since owning my Teac 3340, I can always remember being fascinated with the VU metering compared to how loud something sounded to my ears; and even on the Teac 442 the section on metering in the manual for the early Tascam cassette 4 track was nearly as well thumbed as the section on bouncing down tracks. Digital meters behave so differently to the analogue ones that I grew up with, and it's somewhat reassuring that there are so many emulations of analogue meters for DAW's, even though the metering requirements for digital tracking can be so different. But then, it comes back to that quintessential question - do meters show you how loud something is?

How Loud is Now?

I suppose the first question to ask is how do we hear loudness - and the answer to that is (as far as I can tell at least) is not a simple one.

Robinson Dadson Loudness Contours.

Firstly, the ear is a non-linear device, and the frequency response of the ear is dependent on the volume at which we are listening; still the most common referenced work is by Fletcher-Munson, where as the work carried out by Robinson-Dadson in 1956 was carried out in a free field (i.e. without headphones) and has formed the basis of the most general standards - but in 2003 Suzuki and Takeshima have carried out further studies to propose a new set of loudness curves.

And that's just how loudness affects our perception of frequency - and it does show why we should set ourselves a standard, and repeatable, monitoring volume in our control rooms and headphones; so that we have the same frequency response whilst working (not withstanding ear fatigue). As for amplitude alone, our ears work in such complicated ways that we are sensitive to a massive dynamic range, and our ears can be equally damaged by a high volume transient, as long term exposure to a marginally high volume.

Analogue Kid

Not wishing to harp on about the "(good?) old days", but analogue metering was there to indicate the voltage level of the signal, with the knowledge that any rapid peaks within the system could be handled by the headroom / saturation characteristics of the equipment. The physical weight of the VU meter needle meant that it had a slow response time and that a very rapid spike would not be correctly measured on the meter - somewhat safe in the knowledge that the headroom of the electronics and saturation of tape could accommodate the spike - and even add character (dependent on the quality of the equipment); that was why so much was recorded in "the red". Also, this slow response of the needle essentially gave it an "integration" (averaging) quality, with a rise time of around 300ms, which is somewhat analogous how our ears hear things. One of the biggest problems of the VU meter was the lack of specifications, meaning that there was a massive variability across budget equipment.

A BBC PPM Meter

The PPM (peak programme meter) was (and still is) the professional (i.e. expensive) audio meter and has a different scale and response characterises compared to the VU meter: and a wide range of scales / ballistic options. In the UK, the BBC PPM meter was the format used for broadcast sound, and upon a first look had a very different scale  (1 - 7 with no units, but with a regular 4dB spacing between the gradations) and very specific ballistics.  But again, these meters would let through very rapid transient peaks (based on the assumption that the human ear could not detect very short duration distortion) - with PPM6 (+8dBu) being the "maximum" reading.


Digital World

So, how do a VU meter and a BBC PPM sit in a digital system and on a digital scale? For a VU - the zero point (marked as 0 VU (volume units)) was defined as +4dBu or 1.228 V RMS over a 600 Ohm load; for a PPM (BBC), PPM4 is defined as 0dBu. And thanks to Hugh Robjohns and the Sound on Sound Team, there is a great visual table that helpfully ties the various scales together with the dBFS scale of the digital domain - and in fact the whole SOS article from which this image is taken is a great read.

But what is clear now is that it's not just a matter of different scales and different units, but the ballistics of the meter to suit the job - as a VU meter or PPM will not respond quickly enough to respond to the needs of the digital system, as in the digital domain there is no head room; beyond 0dBFS there is only horrible digital distortion. What's worse is that even a sample peak programme meter (SPPM) - i.e. one that measures the amplitude of each sample, and is commonly found in all DAWs - is not sufficiently accurate. There may be signal peaks between between the base rate sample points that could be 3dB greater than the measured value. This image shows how a SPPM can under read the true peak signal levels - and this comes from an excellent article by Simon Pegg from Broadcast Engineering.



In fact, it was the testing of my meters by using a 12000.1 Hz tone (at a base sample rate of 48kHz) that sparked this blog entry off - and if you want to see how SPPM's can 'mis-read' a signal, carry out this test yourself. The above soundcloud file is three constant amplitude sine waves, one at 12000 Hz, one at 12000.1 Hz and finally one at 12000.5 Hz. Drop it into your DAW or edit suit running at 48kHz, and you'll see your meters displaying a varying amplitude even though the amplitude of the signal is constant. It's because the SPPMs are running at the base sample rate and 'missing' the peaks in the wave form - effectively seeing beating, as the sample rate and the test tone are a fraction of a function of each other. This video from eyeheight explains it really well.

True Peak and EBU R128

This under reading from SPPM means that when mastering up to 0dBFS, that these inter-sample peaks will be being clipped, and that for broadcast the actual transients will be beyond the specifications as identified by the broadcaster. So the ultimate digital meter is the True Peak meter (measured as dBTP) which over samples the digital signal to accurately measure the true peaks within the signal (these meters should adhere to ITU - R - BS1770, and should have 4x over sampling as a minimum). But - somewhat pragmatically - these inter sample peaks are so short, so can we really hear them? And perhaps a simpler solution is just to allow more headroom within our digital mixing.

And now for broadcast, we have a new loudness specification that (hopefully) all broadcasters will be adhering too - EBU R128, (Florian Camerer does as great job of explaining it all here), that introduces the concept of loudness normalisation (normalising to the average volume), instead of peak normalisation (normalising to the peak volume) and so allows us to maintain more dynamic range within the programme material. It (inevitably) introduces a new metering system (the LU - loudness unit), and specifies 3 parameters: 1 - Programme loudness and should adhere to -23 LUFS (this is an average loudness signal for the whole programme), 2 - Maximum True Peak measurement of -1 dBTP and 3 - A measurement of the dynamic range of the programme. What is great here, is that we are finally meeting (and indeed metering) to something akin to a loudness level, as well as a peak and a range.

I've been using an EBU R128 meter for about a year now (zplanes excellent PPMulatorXL), and it really has been a joy to use and work with. I still have my conventional BBC PPM meters in my final bounce bus, but now along with the EBU R128 meter. I find that it's only making small differences to how I work - but then I knew (hoped?) that I was producing mixes that were to specification and had  a good dynamic range; if anything at all, I'm more confident now that I can put louder peaks in there.

Ironically, through this investigation into metering, I found that the TP meter that is part of PPMulatorXL was not quite behaving itself (on a Mac running Pro Tools 10), but the guys at zplane are aware of this, have re-created the problem and are fixing it as I type. Thanks to Martin for his support from Zplane. And also huge thanks to the members of IPSNet (from the Institute of Professional Sound) who helped trouble shoot / explain things.

Please note: there's a lot of very techy information about meters - I've done my best to check that I understand things correctly, and indeed then explain it correctly here. So please read around the subject, and follow the links I've used to get to this point.

Right, back to my meters.

CPD - The IPS Training Weekend 2012

One of the many tricky things about being freelance, is the issue of training and continued professional development (CPD). So it's great that the Institute of Professional Sound run a yearly training course that brings together a range of sound practitioners, from a range of broadcast disciplines, and puts together a two day programme with experts and manufacturers that helps sound professionals develop and continue their training. This years course has just been held at the NFTS in Beaconsfield - suitably entitled Radio Ga Ga - and has covered the trials and tribulations of Radio Microphones.

Radio Ga Ga

The first sessions covered the terminology and theory of analogue and digital / digital hybrid radio microphones. Much of the terminology translates across the analogue / digital divide, but what was interesting was to see how the digital radio mic's fit into our analogue RF spectrum, and the potential interaction between the two systems. The recent Digital Switch Over (or "analogue switch off") in the UK has meant that we have far less spectrum available to us, whether we are working in the electronic handbag, on a drama trolley or a  reality / LE show that requires huge numbers of radio / IEM channels; so what has become essential is that we learn how to make the most efficient use of the available spectrum and our own / hired in radio equipment.

Meet the kit

The Lintec T Dipole

There was a wide range of manufactures and suppliers of radio mic kit present at NFTS, and it was great to be able to go and look, handle and listen to the kit that is currently available and see what is suitable for each application. There was radio mic equipment from Micron, Audio Wireless, Audio Limited, Sennheiser, Sony, Zaxcom, Shure, Lectrosonics and Wisycom. Lintec Antennas and Rycote were also there, as their products are key to the implementation of radio mic's.

Microns's Mini TX with Audio Control.

It was great to have such a range of kit to compare and contrast, and it was great to see in the flesh and ask the manufacturers / suppliers questions..highlights for me were the small transmitter from micron, the amazing flexibility of the Wisycom system, the build quality of the lectrosonics kit, the integration of the entire zaxcom kit (along with ability of the radios to record the audio pre transmission with timecode on a micro SD card), the un-companded sound of the Sennheiser digital mic and the T Dipole from Lintec - that's a specially designed antenna rig that clips onto the harness when working in the electric handbag.


Everything in it's place

Other specific sessions over the weekend covered microphone placement techniques (including a really good comparative listen to just how radio microphones sound when placed on a contributor, and that was one of the most enlightening experiences (huge thanks to Heidi there)), a dedicated look into frequency planning for events large and small (which showed how the DSO has really squeezed the radio mic allocation in BBC TV centre (and who to contact when using RM's there, and at other places)), specific details on the new digital radio mic's from various manufacturers, some insights into the black arts of RF and what to look out and listen for on location (and the JFMG is our friend), and then finally great Q and A with all the presenters which included a tech analysis of the radio mic's that had been brought along by the manufactures looking at their inter mod components, RM channel bandwidth for specific TX's and their masks (and if you don't know what those terms mean, then this course was for you)

And Finally

There's many snippets and gems of wisdom that I've come away with after this weekend's training, but I think for me there were three over-riding themes that should be shouted far and wide:

Firstly, both digital and analogue radio systems has pro's and cons,  but what became clear through out  the course of the weekend was that the best analogue radio mic's have now reached their performance limits, and that although there will 'always' be a place for analogue mic's, the future is looking very much towards digital systems.

Secondly, the value of meeting and talking to fellow practitioners. It's so rare we get to talk to other sound professionals these days, and it's invaluable to catch up and share knowledge. The coffee breaks and meal times offered shared wisdom and experience, just as much as the main sessions did.

And thirdly, if you are using radio microphone in the UK - really check whether you need a license; and if you do, bloody well get one.  The recent DSO has cost the PSME a huge reduction in available RF bandwidth, and this reduction will only continue in the future - and unlicensed users are making a painful rod for their own, and everyone else's, back.  With the recent consultation on WSD's , once again our radio spectrum is under threat, and if it does go ahead, the only way a device will know whether you are there is if you have a license registered on the database.  The JFMG offer a great service and support to RM users in the UK, and the cost of a license is negligible - and if you've not got one, it may just cost you your shoot.

A great course and weekend - when's the next one?

Problems with the Zoom H2 Line Input

Small portable recorders have really established themselves on the market now, and my old Zoom H2 (firmware 1.90) is becoming a bit worse for wear. I've had it for a long time and found it to be an incredible useful device to have in my recording kit, even though I only think of it as 'consumer' as opposed to my 'professional' sound kit. That said, when used in the right way, I've got good recordings with it. I always combine it with my 302 or 442 mixer and have it running as a backup recorder when I'm running sound to camera - such that I have a 2 channel version of the mix (if not the iso tracks) incase there is a problem with the link to camera, or the camera itself.

The Nightmare before Christmas

Recently I was using the H2 (and 302 combo) to record some very dynamic sounds and I started noticing some audible clipping on the peaks on the headphone output of the H2 and something very odd about the meters on the H2 - they appeared to be limiting at about -8dB below full scale. So I did the obvious checks of the limiters on the H2 (they were off) and checked my limiters on my mixer and the limiting on the H2 was happening even before my limiters had kicked in on the mixer outputs. Something was not right.

I did all the usual checks, and the recording level was set to its usual value of '77', which aligns the input of H2 to match -18dB tone with the tape output level of the sound devices mixers. So all seemed fine technically, yet the meters seemed to be hitting some form of brick wall limiter and the audio was clipping.

Expect the unexpected

I returned home and started experimenting with the H2 and researching, and found something fairly gutting: when recording to the H2 Line input, the input level control does not alter the gain structure, but just shifts the recording range and "offsets 0dB" - meaning that it clips at a value less than 0dB. It's such a terrifyingly stupid concept and so fundamentally wrong, that I had to fully test it out to confirm what I was hearing. These tests were carried out with me speaking into a MKH60 mic and steadily increasing the gain until the output from the mixer +20dBu.

H2 Line Input Level 100

The first test is with the line level set to 100 (it's default setting): -18 dB does not correctly align, on the H2 meters, it correlates to about -12dB But you can see as the signal increases from the mixer, the recorder records all the way up to 0dB(FS); and essentially clips in the usual manner - but means that I'm (in essence) losing 6dB of recording range as this is now 'over' the range of the recorder and with any other recorder I'd just reduce the input gain, such that the range matched my analogue mixer.

H2 Line Input set to 77

Now the input recording level has been reduced to 77, which nominally lines up -18dB tone on the scale of the H2. Yet as the signal increases from the mixer, the recorder starts clipping the signal at about -7dB(FS). So, even though I've supposedly reduced the input gain of the recorder, it is now internally clipping the signal at about -7dB(FS) - and this clipping sounds much worse than that at 0dB with the internal limiters enguaged.

And as the recording level is reduced to 60, the effect is even more pronounced.

H2 Line Input set to 60

Pay your money / Take your choice

So now I have the dilemma of what to do, I've used the recorder for years for back ups and rarely had to dip into them and also those recordings have been much less dynamic than those I've made recently. There are two ways to work now to try and keep the H2 as a reliable backup: Firstly keep the recording level at 77, and to set the limiters on the Sound Devices Mixers to be cutting in before -7dB(FS) and so prevent the clipping with the H2. But this is then adjusting how I record just to suit the quirk of my backup recorder; which feels like the tail wagging the dog to me. Or Secondly, leave the levels at 100 on the H2 and let the internal limiters (which are not great) on the H2 stop the peaks that are beyond -6dB(FS) from the mixer - which to be fair would usually be few and far between. Neither is really ideal.

I think the simple answer is that I've got what I paid for, the £120 recorder is a consumer piece of equipment with flaws that I have to live with - but at least I know about them now. When (or if) I decide to use it again, I'll have to be very aware of the limitations.
