controlsurfaceWith great power comes…the A&H iLive T72, finds ALISTAIRMcGHEE; a compact mixer thatdoesn’t hold back.THE REVIEWERALISTAIR McGHEE began audiolife in Hi-Fi before joining the BBCas an audio engineer. After tenyears in radio and TV, he movedto production. When BBC Choicestarted, he pioneered personaldigital production in television.Alistair is now Assistant Editor,BBC Radio Wales, but is allowedout occasionally.& Heath has been brewing digital magic forsome years now. From install products like theiDR8 to the substantial iLive series of systems,llenA&H has been burning the candle at both endsand with its latest products has pretty much covered theground in between. Shiny and new are the R72 controlsurface, and the iDR-16 mix engine and I/O unit.As each model has the same mic pre,let’s firstly have a look at the differencebetween the modules:The iDR-16 houses both the digitalprocessing engine and the bulk of theaudio I/O. The engine is identical inpower to the systems across the iLiverange offering 64 DSP channels and 32mix busses. One nice feature is that theDSP is not shared across the outputs,so you can have full processing onall 32 mixes without robbing Peter topay Paul.If you are currently working witha big copper multi-core, then put theiDR-16 next to the surface and patchaway at your inputs and outputs just likean ordinary analogue desk. The iDR-16mix rack comes with a built-in ACE portto connect it to your surface. ACE isA&H’s own audio over Ethernet solution, and althoughit’s not a network topology, offering as it does only pointto point connectivity, it’s still pretty damn clever.If on the other hand, you are tired of handlingenormous drums of cable – and frankly who isn’t? – thenput the mix rack on the stage and connect it to the surfacewith a long piece of Cat5 string. Allen & Heath says youcan run up to 120m, but sells you an 80m drum. I wouldsuggest you err on the side of conservatism, not becauseI’ve had a bad experience, but only because your wholeshow is going down this Cat5 and that’s a lot of egg forone face. Check out the A&H website for full cable info.Back at the surface you have some I/O built in – fourbalanced line inputs on jacks, a pair ofunbalanced phonos, and a coaxial spdif.The outputs have the same connectionconfiguration and there’s also anXLR input for a talk back mic and aheadphone socket (actually two; onebig, one little) for monitoring.Small On Size OnlyThe R72 is the smallest Allen & Heathcontrol surface yet and comes in a19-inch rack friendly package thatfeatures 12 faders divided into 8 + 4, andwith six layers, hence the 72. Squeezingsuch a powerful mixer into a such a smallfootprint does entail sacrifices, and Allen& Heath has put pretty much all of themixer configuration onto the onboardtouch-screen computer.In the original iLive series, A&Hoffered a horizontal channel strip, allowing direct accessto a wide range of parameters for the selected channel.In other words, you had lots of knobs for functions youneeded to access in a hurry. If you bought a big enoughsurface you would get the whole channel strip to playwith. The R72 simply doesn’t have room for all those34AUDIO MEDIA APRIL 2010

The actual channel stripsseem identical to me to those on its bigger brethren,meaning you get two top bonuses. First, everychannel has a small LCD screen built in, which allowsyou to colour and name the channel and display mixinformation and other valuable stuff. Colour codingand naming your channels is a real winner. On otherconsoles at this hotly contested end of the marketyou can name the channel, but as you can only seethe name of the channel you have selected, it doesnothing for your overview. But I hear you say, ‘that iswhy they invented Post-It tape, so there’. Ah, Post-it isfine for an unlayered console, but do you really thinkyou can stick three strips of tape one above the otherand have any chance of finding the channel youwant in a rush? Personally I prefer having coloured,named labels on every channel that change as I goup and down the layers.Lowest noise floor in its class (3.7 dBA)A classic in its own time, the sophisticated new EquitekE100S, engineered and built in the U.S.A., has the smooth,rich tone with full low end CAD is known for.

In combination with theshift key and alt-view you can have three functionsper rotary. So for my preference, gain at the top leveland pan on the shift key. It may be something to dowith different work flows, but not having gain at thetop level of accessibility on many digital desks is areal drop off. How many times have I reached out tothe tweak the gain on the ‘selected channel’ and idlywondered why I can’t hear any difference on mic A,only to realise I have been gaily altering mic F? Those days are gone with gain on the rotary.CADAUDIO.COMAUDIO MEDIA APRIL 2010 35
