When switch “A” is engaged, signal to the DAW is post-EQ and post-insert. Switch “B” replaces the mic/line input with the DAW return, pre-insert and pre-EQ. That means that rear panel analog inserts and channel EQ apply to the DAW returns—a really slick feature. Switch “C” also engages the DAW return, only this time it’s post-EQ and insert, so you can monitor the DAW output while using the EQ and insert on the signal going to the DAW. Switch “D” is fader bypass at unity gain. When you want to mix “in the box,” use the Digital Master Return to monitor (see below), and set D for bypass so that moving a console fader changes the DAW fader but leaves the channel’s audio level untouched. On the other hand, you can turn off D, set the DAW channels to unity, and use the GS-R24M as a summing mixer.

OUTPUT SECTION
Each of two studio outputs can independently source from any output bus. The master section is equally impressive with LED metering for the L/R bus (this, in addition to the meter bridge VUs), talkback, headphone out, control room monitor source, alternate speakers, control room level, and a mono button. Dubbing switches allow copying from 2-track 1 to 2-track 2 or vice versa, which is very convenient. “Digital Master” is a virtual 2-track return from the DAW on buses 31/32, which I used as the stereo return from Pro Tools and Digital Performer. Beware that the digital master return can be dumped back into the L/R mix, setting up the possibility of a feedback loop.

MIDI CONTROL
Before we discuss the GS-R24M as a DAW controller let’s make clear the separation of control and audio functions: The GS-R24M functioned flawlessly as the audio interface to my Mac Pro at all sample rates, regardless of clock source (I used internal, word and ADAT clock) and software (Pro Tools, Digital Performer and Record). Inputs and outputs automatically appeared when I launched software (albeit with some difficult-to-read names) and routing was a snap.

Using the GS-R24M as a DAW controller was disappointing. The desk requires purchase of a third-party utility called Bome’s MIDI Translator (approximately $85 U.S.), for which A&H provides mapping templates. At this price the desk should include all requisite software. The manual states that the console may be run in HUI emulation mode, but the template does not support fast-forward, rewind or fader banking—so there’s no fader control over channels past 24. To take full advantage of DAW control, be prepared to write your own Bome template. Fader read/write/on/off switches allow fader moves on the GS-R24M to be recorded by your DAW’s automation, and the console faders respond to DAW fader moves. At times, though, faders resisted manual movement (even with automation deactivated), or the DAW faders would not reflect movement of the hardware faders.

I also discovered an issue with the GS-R24M’s HUI mode. When the desk is set to HUI mode, the GS-R24M produces a MIDI tick. This tick cannot be isolated and infiltrates MIDI tracks when you attempt to record MIDI data from, for example, a keyboard controller. Setting the MIDI track’s input to the keyboard controller (as opposed to “all”) did not clear the issue, nor did turning off MIDI read/write on the faders. In fact, even if I removed the GS-R24M as a Pro Tools peripheral, the tick was still present in the MIDI stream.

AND FINALLY
Allen & Heath’s GS-R24M fantastically merges the requirements for routing and mixing DAW tracks with analog sources. It provides incredible flexibility for recording DAW tracks while monitoring the sources and/or creating front-of-house and monitor mixes. As expected from A&H, the audio path is clean and quiet, the mic pre’s are well designed and the desk features the company’s familiar EQ. As it stands, the GS-R24M is an excellent mixing console. If A&H make access to DAW control easier for Mac users, the GS-R24M will be a tour dé force.

[Ed. Note: As we went to press Allen & Heath was finalizing the implementation of the HUI protocol directly into the console, eliminating the need for the BOM Software translator. This will be a free firmware update to the console available in the very near future.]
