Boom Poles

The humble boom pole is a constant feature of film and video production.
While radio mics have proliferated every facet of production filling up all of those extra channels that mixer manufacturers have been giving us, the boom is still correctly regarded as the "proper" way to capture audio for a film. With larger fuller sounding mics that can be placed in the correct location for speech pickup the boom mic has prevailed.
If the film is being shot on an iPhone, the sound still relies on its traditional form factor, and while powerful multitrack packages can fit very small bags (see my previous post "Small Packages for Professional Sound", it is still the mixer, boom and radios package required to record audio that sounds good.

A boom pole denotes a film crew, it's the first thing you might notice popping out above a crowd of people before you see the camera or hear the shout of action from the director.

What I'm here to talk about though is the boom itself. What it does, the different sizes and what those different sizes might be used for.
If you're just starting out as a sound recordist or boom operator then you probably got a Rode aluminium pole. It's cheap got decent reach, and folds up reasonably sized, but it weighs a lot for a professional boom that you're going to be using as the main tool of your trade. Save a little and you'll want to step up to something a lighter and more pro feeling.

The biggest names in the game are Panamic, Ambient, K-Tek and VDB. These companies have been providing poles for every level of the game from features to short documentaries for decades.
Panamic are probably the most highly regarded in the world of feature films. They've been swung on all of the biggest films and they have a reliability that goes relatively unchallenged.
Ambient have also been making poles for a very long time. Their feature poles are very highly regarded and are very high spec. They hand make their top poles and offer booms that can fold down and fit in hand luggage, right the way up to 17ft feature film beasts.
K-Tek have picked up a great following among documentary style sound recordists. Their carbon poles are very light and offer an excellent extension ratio.
VDB have also been making poles for a long old time. This French manufacturer claims the crown for the lightest poles for any given extension. Some say that comes at a cost of fragility at extreme lengths, but those boom operators with the touch to handle them swear by them.

A boom pole can be categorised a a few ways, but most people see the distinction as relatively straightforward. There are doco poles and there are feature poles.
A doco (documentary) pole is a pole with a reach of under 15ft. They have a numerous sections, usually five or six, in order to both have good reach and be small enough to pack away into a relatively small case.
A feature pole has a reach of over 15ft and can go on right up to 20ft. They are long so as to keep clear of action and to ensure that the boom operator can stay well clear of camera moves. Typically, due to the nature of extending a pole to those lengths, a feature pole will have fewer sections usually three or four, and will be made of slightly thicker material in order to retain rigidity on long extensions.

But what does this all mean?
Well I suppose the rest is really up to you. What work you do and how you want to go about that work. I have poles for different occasions. A small pole for travel a medium one for indoors and a massive feature one for those big time shots!

Small Packages for Professional Sound

While the capabilities of cameras have been squeezed into smaller and smaller packages, to the point where a handful of feature films have been shot on iPhone cameras, sound kit capable of delivering professional level clean audio hasn't quite shrunk to the same level, and remains similarly sized to kit from the last 30 years. There's always at the very minimum a shoulder bag with a recorder/mixer and a boom mic.

One example of a tiny professional recorder is the Sonosax MiniR82, a recorder about the size of a well filled wallet (which Sonosax would gladly empty in order to own one), small enough it could feasibly fit in a pocket. However, you'd still need the boom mic and cable running to the unit, making the package considerably bigger and thus unwieldy to use without a specifically designed pouch/bag/case system.

However, what I'm investigating with this article is the "standard" PSC/ENG sound package and what can be achieved with new technology to make it smaller lighter and healthier. It used to be that a sound person on a small shoot would turn up with his SQN, maybe a couple of radio mics and a boom, and connect to camera for recording. These days it can be acceptable for a recordist on a reality show to be covering up to 12 radio mics in a bag, with mix panels and enough battery power to run all of the receivers and the mixer/recorder all day. This all starts to add up rather quickly when the Sound Devices 688 or 664 start at around 3kg, before you start adding the CL6 mix panel and and SL6 six channel radio mic slot interface, plus big NP1 batteries to power the lot for a few hours.

My personal goal has been to reduce the weight in my bag over the years. It's something our advances in technology should be allowing. I want strong, lightweight materials, miniaturised electronics, and software based UI to reduce front panel space. For me only two devices have come close to these goals, the delightfully pricey Sonosax SX-R4+ and the rather cheaper Zoom F8. Both weigh less than 1kg without batteries and have 8+ channels, with small footprints and make use of modern tech in ways I can appreciate.


I'll start with the Zoom F8... This box has eight analogue inputs all on split mic/line connectors. No other recorder has this. As the most widely used connection system for mics XLR connections offer an incredibly low cost way of getting eight channels into a recorder, without having to go down digital routes like AES. The software UI is as intuitive as can be expected, but the front panel controls are a little cramped. That is overcome when in "cart mode" using the optional USB fader controller, which gives better tactile control over the mixer. I'd be really keen on a small eight rotary fader panel for bag use too, but Zooms development team don't seem to be showing all that much love for the product range at the moment.


Then we have the Sonosax SX-R4+... This is probably one of the most technologically advanced recorders on the market. The base unit is a 16 channel recorder, which has six analogue inputs (4x mic & 2x line) and five sets of AES3 inputs split across two connectors (1x multi pin DB25 and 1x TA3). The TA3 input is also assignable as output with SRC to connect lower sample rate AES devices. It also has an optional RJ45 on the side to allow communication with audio over IP systems like Dante.
The base unit is then expandable through the multitpin AES connector to have a couple of options. The first is the RC8+ eight fader panel, breaking out the AES inputs onto 4x TA3 and providing extra hirose power outputs, from the internal Audioroot battery, for radio mic receivers and the like. The second is the AD8+ which gives the SX-R4+ eight additional mic inputs.

These two systems are perfectly suited to small high channel count rigs that weigh in at not much more than 5kg with batteries and mic receivers. With the recent proliferation of dual channel radio mic receivers it is possible to fit eight channels of radio mics into incredibly small packages with just four receiver units. This allows systems to be put into incredibly small bags like the K-Tek Stingray Jr without breaking the spine of the operator!

Case study
Here's my complete setup from a shoot for an online commercial which fits handily into a K-Tek Stingray Jr.

A Zoom F8 running six channels of radios; two Audio Ltd EN2 dual receivers and two Sony UWP-D single receivers. I was also rigged with a Sennheiser G2 transmitter feeding my G2 IEMs. The EN2's and the Zoom F8 were powered by my usual Hawkwoods NP-F shoe and a Baxxtar NP-F990 75Wh battery which ran all day. The Sony receivers and the G2 transmitter were powered by Eneloop Pro 2450mAh AA rechargeables.
All in the package was fairly lightweight at a very reasonable 5.6kg, and remained compact within the confines of the Stingray Jr bag.
The boom was wired, phantom power provided by the F8. All-in-all a super compact and surprisingly low power drain system which could easily scale to eight radio channels, with power consumption rising rapidly with the addition of digital receivers.
In a world where digital radio transmission is making more and more sense, an upgrade to a 98Wh AudioRoot or NP1 Lithium battery might be a good move for power stability.

New Gear Day // Audio Ltd A10 Digital Wireless (w/ DPA Core 4061 mics)

Excitement levels off the scale, I've just taken delivery (actually two weeks ago now) of my own first truly professional level wireless audio system.
The dual channel Audio Ltd A10 digital wireless system.



I've been meaning to get off the Sennheiser G2/3 wagon for a while now, and have finally mustered the courage to splurge the balance of my credit card on a complete set of radios, plus mics.

Last month I added 2 sets of Sony UWP-D radios, with ECM-77 mics, to achieve better audio quality and better transmission strength. I was very happy with those, and continue to be; as I'll be using those as both radio camera links and as additional mic packs too. The Sony RX's have the advantage of having incredible integration with Sony cameras like the FS5 and FS7, when used in conjunction with their powered hot shoe adapter, and I just can't deny how popular those cameras are among owner operators, and their prolific use for corporate video and low/mid tier commercial projects.

Now with my work year picking up again, I'm preparing by getting the best of the best kit to help me deliver better sound to my clients! The Audio Ltd A10 system, which has been on my radar for a year or so now, should be just the ticket for delivering better, cleaner radio mic transmission.
It combines the immense audio quality associated with Audio Ltd products, with a lightweight pack low latency digital transmission and integrated recording for those out of range moments. Only Zaxcom, from the US, have a truly 1 for 1 competing product; Sennheiser and Sony also have digital systems, but without that integrated recorder.

From the two weeks I've now had using them on locations across Europe I must confess I'm impressed. Almost cable quality transmission of the DPA mics, with bluetooth control of key functions; gain, LCF, frequency, and that 48V phantom power adding the option of a wireless boom is a great addition to my toolset.



I think it's fair to say my radio mic game will be lifted by this product!

Can Sound Be Light?


In a desperate attempt to save my spine from years of abuse I have been considering the weight of the kit I carry across my shoulders. In doing so I've been compiling statistics on the earthly mass of every bit of kit I carry with me; and, by way of comparison, every other alternative part that could make up a sound-persons bag and boom. I've created a selection of handy tables and decided to share my findings with you, the people of the internet.

Gear Review: Allen & Heath Qu-16 Digital Mixing Console. UPDATED

     Allen & Heath have long been on my radar as a company that builds equipment that has quality far beyond its price placement within the market. In the whole space for analogue and digital mixing consoles in the £1000 to £2000 price bracket not a single one of the desks has all of the features that I've wanted to see. There's always one or two trade-offs to allow for some other forward thinking feature. The Yamaha 01V96i has card expandability, but only 12 mic pres. The Focusrite Control 2802 has 32 inputs of analogue summing and a glorious bus compressor but no EQ on the channel strip. The Allen & Heath Zed R16 has 16 solid pres, EQ's on everyone and flexible digital routing, but is cramped to operate with only 70mm faders and very narrow channel spacing.
     The Qu-16 from Allen & Heath has it's own special feature. 18 channels of direct to USB hard drive recording. It also has 16 high quality mic preamps, a selection of stereo inputs and FX returns. Two built in digital FX sends and twelve mix outputs. This is a desk designed for live use but with plenty of recording grunt and comes in at a very affordable price for the features.

     UPDATE: The Qu-16 has now been updated a few times and as such I've added a bit of extra insight to some of those new features. Most valuable to me is it's ability to now control DAW systems under Windows operating systems natively, making it a great hub around which to base a studio.
