Allen & Heath has a long history of making classic recording mixers such as the Sigma, Syncon, System 8, Saber and the GS3000, but for a few years have concentrated on the live sound, installation and pro DJ markets. The GS-R24 resurrects the GS product line and stands as a classic recording console for the modern age of Digital Audio Workstation software. We spent a long time examining how modern recording methods, equipment and software applications have changed the way musicians and sound engineers work and listening to ideas and requests on forums such as Gearslutz, we have created a product which offers more than a sum of its parts—a combination of not just different technology, but different methods and philosophies. GS-R24 is designed to fulfil the needs of musicians, sound engineers and producers and is adaptable to different workflow methods. Briefly, some of the capabilities of the GS-R24 include: • Multi-track recording to the digital domain with easy interfacing to a computer DAW with zero latency monitoring of live sources. • Multi-track recording to the digital domain with monitoring sourced from the recorded track in the DAW. • Over-dubbing a recorded track whilst monitoring the track and/or live source. • Multi-track mixdown using state-of-the-art analogue summing techniques. • Multi-track mixing performed in the DAW using the GS-R24 as a controller. • Patching, routing and monitoring a comprehensive matrix of signals in a studio environment—artists monitors, effects processors, external devices and studio control room monitors. • Surround sound mixes can be created in a DAW and conveniently monitored through a single level control. • Automating a mix using the motorised faders on GSR-24M to either create an automated mix in the digital domain or create an automated analogue summing mix using the faders for channel level control as well as parameter control. Our claim that the GS-R24 is a modern classic recording console is not without foundation. It is a progression of our in-line recording mixers, many regarded as “classics” but with interfacing to each channel provided by a Digital Audio Workstation. Actually, the GS-R24 isn’t just designed for modern times—it is built with the future in mind, with the interfacing hardware housed in a removable module which can be swapped and updated over time. This means that you won’t have to change your lovely console when you need to upgrade your digital interfacing technology years from now. The GS-R24 is built utilising individual vertically mounted channel circuit boards with each rotary control fixed with a metal nut to the front panel. This provides a very robust product that will resist damage and give years of reliable use. It also makes servicing easier should it be required. The motor fader system can be removed separately to the rest of the system and faders can be changed individually if the are damaged (from top impact for example). Mic/Line Pre-amps: The ultimate performing pre-amps are fitted to GS-R24. Similar in topology to those used in the renowned ZED-R16, they comprise a symmetrical circuit with individual linearising feedback to both phases, along with the lowest noise transistors available, providing very low distortion over a wide bandwidth and extremely low noise which translates to superior clarity and dynamic range. EQ: Extremely powerful, flexible and fully implemented mono channel EQ. Parametric mid sections with extended frequency range and controllable Q- factor allow a huge range of corrective and creative possibilities. MIDI Control: We have developed the control aspect on GS-R24 to give an intuitive, flexible, easy way to control multiple parameters in a variety of DAWs. Each of the mono channel faders has MIDI capability and are motorised on GS-R24M. In addition there is a MIDI Select switch on each channel and in the MIDI controller section 2 x 60mm faders, 12 x rotaries, 14 switches plus transport controls and a jogwheel. Interface Modules: The interface module fits in the rear panel of the console. It handles 32 channels in and 32 channels out plus the control protocol. This manual does not cover the details of the modules as the variety of modules available will change in the future. Please consult the A&H website for details and the User Guide for the individual modules.

The signal is sourced prefade which means that the level is independent of, and unaffected by the fader. Auxes 1 & 2 are primarily used for foldback monitoring purposes, as the fader does not affect the level. These sends are affected by the Mute switch by default, so muting the channel will also mute the Aux sends but they can be selected to be independent of the mute status. The control varies the signal level to the bus from off (fully attenuated) to +6dB, with unity gain at the arrow. There are master level controls for all of the Auxiliary outputs situated in the master section of the mixer. 1 +6 AUX 2 +6 AUX 3 Auxes 3 & 4 The source for Aux sends 3 & 4 is normally post-fader but can be selected pre-fader by pressing the Pre switch. +6 AUX 4 Auxes 5 & 6 +6 The source for Aux sends 5 & 6 is post-fader by default. They are also muted by the Mute switch. Auxes 5 & 6 are primarily used for effects sends. However, an internal jumper option can be altered to select them to be sourced pre-fader, for example if more monitor sends are required. Pre AUX 5 PAN +6 The pan control adjusts how the signal from the mono input channel is shared between the left and right buses and between odd and even group buses. AUX 6 Bus Routing Switches +6 PAN L R M L-R BUS 1-2 3-4 A C B DAW Allen & Heath The L-R switch connects the post-fade signal to the main L-R mix bus via the pan control. For minimum noise from the mix bus summing amplifier, leave the switches in their up positions if the channel signal is not required on the bus. The M switch routes the post-fade signal to a mono mix bus which is independent of the pan control. The 1-2 and 3-4 switches are for routing the post-pan signal to pairs of audio sub-groups which have independent insert points, master faders, outputs and sub routing to the main mix buses if required. D 14 GS_R24 User Guide MONO INPUT CHANNEL A B C DAW INTERFACE CONFIGURATION SWITCHES DAW send source switch D A MUTE SOLO/ SELECT Switch A determines the source for the interface send for each channel. In the up position the source is just after the pre-amp and Hi pass filter. If pressed in, then the source is from after the EQ IN switch. One or the other signal will always be sent to the interface. DAW return to channel (Pre Insert) switch B Switch B selects the source for the channel to be the interface return, which is switched in at just before the channel insert point. In other words the preamp signal is replaced by the interface return for that channel just before the insert point. DAW return to channel (Post EQ) switch C Switch C selects the source for the channel at a point after the EQ. So if pressed, the channel signal from the EQ is replaced with the interface return for that channel which then feeds the fader and also the pre-fade sends. Fader Bypass switch D Switch D allows the channel level control element of the fader to be bypassed at unity gain. This is useful when using the fader purely as a MIDI control device when also utilising the channel audio path for mixing or monitoring but not wanting fader movements to affect the channel signal level. 10 For a graphical explanation of the interface configuration switches, and interface routing options please refer to page 39. Mute Switch 0 This mutes or cuts the signal to the mix buses, the post-fade Auxes and the pre-fade Auxes (where muting is enabled). A rectangular LED illuminates to show the Mute switch is pressed. The “soft” mute circuit has a time constant of 30mS for minimum Fourier clicks caused by sharp edges, and can be triggered by soloing another channel in Solo in Place mode. Solo/Select Switch 10 20 30 40 Allen & Heath The channel solo/select switch is multi-functional switch that operates as a channel solo switch or a MIDI select switch to control DAW parameters, The modes are set by selector switches in the master section and are as follows: 1) PFL: Sends a pre-fade (also pre-mute) signal from the channel to the monitoring system. 2) AFL: Sends an after-fade (also post pan) signal to the monitoring system. 3) Solo in Place: Any pressed solo switches will mute other mono input or stereo input channels (unless SiP safed) unless their solo switches are pressed also (in ADD mode). 4) Select: The channel monitoring is disabled and the switch sends a MIDI message. The LED illumination can be tallied internally or can be tallied by the DAW in order to maintain synchronisation of status. Fader A 100mm fader controls the level of the channel signal path to mix buses and post-fade auxes. The mono channel faders can also be used as MIDI controllers for parameters in DAW software. On the GS-R24M the faders are motorised, further information on page 32. 15 GS_R24 User Guide STEREO INPUT CHANNEL REAR PANEL CONNECTIONS ST1 IN ST1 (& ST3) Phono sockets Standard RCA phono sockets for unbalanced stereo inputs.

The signal is sourced prefade which means that the level is independent of, and unaffected by the fader. Auxes 1 & 2 are mono buses so the stereo pre-fade signals are summed together to provide the source for the send. These sends are not affected by the Mute switch by default, so muting the channel does not mute the Aux sends but they can be selected to be postmute where they will follow the mute status (internal jumper links).

Wired Tip=Hot(+), Ring=cold (0V), Sleeve=Chassis. Microphone Input Socket Standard 3-Pin XLR socket wired as Pin 1=Chassis, Pin 2=hot (+), Pin 3=Cold (-). FRONT PANEL CONTROLS I/P=DAW switch I/P = DAW INST +48V POL BOOST INST 0 20 30 40 GAIN -14 Line/Instrument Input Switch Selects the source for the pre-amp from XLR to Line/Instrument input jack. The jack input is extremely high impedance (10MΩ) and utilises a class A FET circuit as a front end to the pre-amp. This in itself emulates a thermionic valve input stage in its tonal quality and saturation characteristics. 48V Phantom Power Switch 50 6 This swaps the source for the valve stage from the Mic/Line/Inst sockets to the interface return for that channel (channels 29 & 30 on the interface). The pre-amp Gain control will not affect the return level when sourced from the interface, but the Drive control will. 60 40 Applies +48V to pins 2 and 3 of the XLR input though 6k8 resistors for phantom powered condenser microphones. Boost Instrument level switch Increases the gain of the FET pre-amp by 26dB when pressed. Useful for low output pickups of when the saturation characteristics of the pre-amp circuit are utilised. Important! This switch is liable to cause clicks or thumps when pressed—turn down your master level to avoid unwanted clicks. MIN MAX Drive Allen & Heath Polarity (phase) reverse switch Reverses the polarity of the balanced input signal phases for both mic XLR and Line jack inputs. 20 GS_R24 User Guide VALVE INPUT CHANNEL 0 20 30 Gain Control 40 GAIN -14 This adjusts the gain of the input amplifier to match the signal level of the input. The gain is varied from +6dB to +60dB for signals plugged in to the xlr socket (Mic Input) and –14dB to +40dB for signals plugged into the Line/Inst input jack (without Boost being pressed). The Gain control does not affect the signal if the input is sourced from the DAW interface. 50 6 60 40 Drive control MIN The Drive control determines the amount of signal that passes through the valve stage and therefore the amount of signal with thermionic valve pre-amp characteristic. In addition to increasing the amount of even harmonic content, the volume level may also be increased when swept towards the MAX setting.

This will override any AFL monitoring from the master section AFL switches. SOLO MODE PFL MODE SIP OFF = SEL MODE AFL MODE switch AFL MODE In AFL mode (AFL MODE switch pressed, PFL MODE not pressed), an input channel Solo switch will send a post fade, post pan signal to the stereo AFL bus and trigger the AFL monitoring in the master section. This will sum with any AFL monitoring signals selected in the master section. ADD MODE Solo in Place MODE SOLO CLEAR If both PFL and AFL mode switches are pressed then the monitoring system is set for Solo in Place. If a Solo switch is pressed on any input channel (mono or stereo input), all other un-pressed input channels will be muted. There is a SiP Safe switch on each stereo input channel to inhibit the muting function. The SiP system does not activate the monitoring circuitry in the master section, so will not illuminate the PFL/AFL active LED by the monitor meters, instead there are indicator LEDs in the meterbridge. Select MODE If neither PFL or AFL mode switches are pressed, the mono and stereo input channel Solo switches operate as MIDI select buttons. Further information about the MIDI functionality can be found on page 32. ADD MODE switch Normally the channel Solo switches are exclusive—so they cancel any previously selected Solo switch. In Add mode they do not cancel so more than one can be selected at a time. SOLO CLEAR switch AFL R BUS PFL BUS AFL L BUS Clears any active Solo switch. Illuminates when any Solo switches are active.

Allen & Heath 29 GS_R24 User Guide MIDI CONTROL MODES OF OPERATION SOLO/SELECT switches in SEL mode If the Solo mode is set to SEL (both PFL and AFL mode switches set to their up position, then the channel Solo switches function as MIDI select switches primarily designed to map to DAW functions such as track solo, track mute or record arm. Pressing the switch will send a MIDI message via the MIDI out on the interface module which can either be mapped, learned or translated by the DAW or computer software. The LED illumination of the switch can be set to either follow the switch press only (internal tally) or to follow the status of the function mapped in software by responding to MIDI input (external tally). This is set by the console mode configuration on power up described on page 37. SOLO/ SELECT Channel Solo/Select switch SOLO MODE PFL MODE OFF = SEL MODE SIP AFL MODE M The Select switches can work in the same fashion as the PFL/AFL system where in ADD mode more than one can be selected simultaneously, otherwise pressing a Select switch will cancel any previously selected. Also, the Solo Clear switch illuminates when any are active, and will clear any selected. MIDI FADER MODE switches ADD MODE The fader mode switches configure the operation of the MIDI enabled channel faders. The switches function differently depending on whether you have the GS-R24M with motorised faders or the GS-R24 without motorised faders. SOLO CLEAR GS-R24M GS-R24 READ MONO CH MOTOR FADERS MIDI ENABLED WRITE MONO O/P MIDI FADER MODE OFF = NO FADER MIDI Master section Mode switches Read/Mono Channel Fader enable switch GS-R24M: When this switch is pressed the 24 mono input channel faders will read MIDI data from the MIDI input on the interface module and if valid commands are received the motors will engage and move the fader to the position required by the received data. GS-R24: Enables MIDI data to be sent from the 24 mono input channel faders to the MIDI output on the interface module. If not pressed then no MIDI data will be sent from the mono input channel faders. Write/Mono Master Fader enable switch GS-R24M: This switch enables MIDI data to be sent from the 24 mono input channel faders to the MIDI output on the interface module. If not pressed then no MIDI data will be sent from the mono input channel faders. GS-R24: Enables MIDI data to be sent from the Mono bus master fader to the MIDI output on the interface module. This allows a single 100mm fader to be used to control MIDI parameters. The fade function on the Mono output signal is bypassed at unity gain when this switch is engaged. Fader Touch Sensor GS-R24M: The motor faders are equipped with a metallised fader knob which senses touch and turns off the motor if the motor is moving the fader, and activates the MIDI signal send from the fader if the fader is in WRITE Enabled mode. The fader will send the MIDI data for fader position whether moved or not as soon as it is touched. Multiple faders can be touched and will send MIDI data simultaneously. The Touch Sensor works in two ways: a) by conducting a tiny amount of electrical current through the fader knob to the operator if the operator has contact with another fader or the console front panel, or b) by signal pickup through the operator originating from an electrical field in the vicinity. The touch threshold is set so as not to be triggered by the fader itself when moved so in some insulated and low electrical field situations it may be necessary to increase the sensitivity when touching a single fader. This can be done simply by routing a mains electrical lead in the proximity of the operating position for the console, or by the user touching a metal object on the console front panel (such as one of the fader screws) before touching the fader. Allen & Heath 30 GS_R24 User Guide MIDI CONTROLLERS MIDI 127 1 MIDI 2 127 60mm MIDI faders Two 60mm faders are provided for assigning to parameters in your DAW that can be controlled by MIDI. They are permanently enabled so will send MIDI data via the MIDI output on the interface module whenever they are moved. Rotary MIDI controls Twelve rotary MIDI potentiometers are provided to control rotary type parameters in your DAW such as track Pans, Send levels or processing controls. These are purely one way MIDI controllers—there is no bi-direction tally or feedback, so DAW features such as MIDI pick-up mode may be implemented when controlling multiple parameters with one control. O O Transport control switches Five switches primarily used for transport control of a recording system— either in a DAW or a hardware device such as a tape machine. The default standard in MIDI Machine Control (MMC) but can be configured to send MIDI note on/off data. The Stop, Play and Record switches can be configured so that the illumination either tallies internally or externally via MIDI message feedback. MIDI switches Fourteen switches send MIDI data for assigning and controlling parameters in your DAW. The switched labelled 1 to 8 have illumination that can be tallied either internally or via MIDI feedback from a DAW.

Heath MIDI CONTROLLER 34 GS_R24 User Guide POWER-UP CONFIGURATION MODES MIDI Operation modes It is possible to set GS-R24 to work in different ways depending on preference and the capability of externally connected equipment. These modes are primarily concerned with setting up the illumination of the Solo Select switch LEDs so that they tally entirely from the console function or from external MIDI messages received by the console. The modes can also set a tick message which is required when translating the GS-R24 default MIDI code into the HUI protocol, change the transport from MMC to note on/off, and set the console into self test or demo mode. To Set the configuration mode: Power the console ON whilst holding down PLAY Release PLAY and press one of the following Solo/SEL buttons At this stage the Solo/Select switch LEDs will display the current mode status.
