GL2200 USER GUIDE

STEREO RETURNS

Two stereo return inputs are provided with 2-band EQ, sends to auxes 1 & 2 and

routing to L-R mix or groups 1-2/3-4. These are normally used to return the effects

(‘wet’) signal, usually from a stereo device, to the mix. They can also be used for

additional line inputs to the mix.

A 2 band EQ provides HF and LF control with 15dB cut and boost at 12kHz and

80Hz respectively. This is often used to remove unwanted high or low frequency

noise from effects devices.

2 aux sends are provided to feed a summed left and right pre-fade post mute

signal to auxes 1 & 2. This is ideal for returning effects to the monitors without

using up valuable channel inputs.

The BAL control adjusts the balance between left and right signals, or can be used

as a pan control to route the signal to one side only by rotating fully.

MUTE switches the signal off when pressed regardless of fader position. Muted

Returns are indicated by red LEDs. Mute does affect the pre-fade aux sends.

Pressing PFL lets you listen to the channel pre-fader signal on headphones

without interrupting the main console outputs. The signal level is shown on the L-R

bargraph meters. In this way each sound can be correctly lined up and checked at

any time.

L-R/1-2 (3-4) ROUTING SWITCHES - In the up position the signal is routed to the

main L-R mix but may be returned to the corresponding pairs of su/jointfilesconvert/461238/bgroups for

group effects (1-2 or 3-4).

A smooth travel 60mm FADER provides precise control of the level.

AUX OUTPUTS

AUX MASTERS

Each aux mix has a master level control that adjusts the output level to match external

equipment, or to trim the monitor or effects level without affecting the mix balance. Up to +10dB

of boost is available above the nominal ‘0’ position. Auxiliary outputs are on 3-wire impedance

balanced 1/4” TRS jacks.

AFL (After Fade Listen) routes the post mix signal to the console meters and headphone

monitoring to allow checks for sound quality and mix level.

If MODE SWITCHING aux/groups reverse is in operation, aux master level controls are

connected to the corresponding group busses (Group 1 to Aux Master 1, etc...). Refer to

MODE SWITCHING section on page 17 for more information
