TEREO 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 subgroups for
group effects (1-2 or 3-4).
A smooth travel 60mm FADER provides precise control of the level.

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
