Allen&Heath GS1 USER GUIDE

The GS1 is the only true 8 buss recording console at this price level. It is sonically transparent and specifically designed for digital multitracking.

You will find this ultra compact console is outstanding as a professional tool, designed and built on a well proven operating format using well proven technology.

We have incorporated the latest in Mic pre-amp developments. We out perform conventional designs and we have given the GS1 127dB EIN, a flat transparent frequency response of 10Hz to 30kHz (+0/-1dB). The Mic Input to Insert send (Direct out) is rated better than 300kHz (-1dB).

We hope you will enjoy using the GS1. Welcome to Allen & Heath.

M

ONO INPUT

Main input gain control allows optimum settings of input signal. Set this level using PFL and the Master Meters.

Use the Mic line switch to select the input source. When no input is connected to the line socket this switch acts as a 30dB pad on the Mic input.

(See section 5)

The insert socket sends the input signal to an external device. This may be a gate, compressor or de-esser. The signal returns to the same point in the channel path. See the diagram in the connector section for correct wiring.

S

TEREO INPUT

If only the left input is used the signal appears on both left and right paths, effectively mono.

HANNEL EQ

Each mono channel strip has a three band EQ. The mid sweep ranges from 300Hz to 12KHz.

S

TEREO INPUT EQ

Each stereo input channel has a two band shelving EQ.

On each EQ the HF shelf starts at 12KHz. The LF shelf starts at 80Hz. Each level control gives 14dB of cut and boost. A centre detent position makes it easy to find the ‘off’ position.

HANNEL AUX SENDS

There are five Aux busses on the GS1. These are typically used for sending channel signals to common FX such as reverbs and delays. Auxs 2-5 are always post fade. Aux sends 4 & 5 are accessed by pressing the Channel Aux send select switch.

M

ASTER AUX SENDS

Aux 1 can be switched at the master section to be pre fade. A pre fade Aux is commonly used for foldback or cue for a musicians headphone mix where the monitor signal is not affected by channel fader. In most cases foldback will be required from the tape returns, When Aux 1 is switched to pre, it selects the TAPE RTN signal path from the mono channel strips.
