39 MONO CHECK
Normally the Phones output monitors the Stereo Mix. Pressing the MONO CHECK
switch sums the L & R outputs to check for phasing problems. The main outputs are not
affected by the position of the switch.
40 MUTE MASTERS
Four MUTE MASTER switches provide muting control of any channels which have
been assigned to a mute group using the M1-M4 switches on the input channels. The
associated LED illuminates when the MUTE is active.
41 PHONES JACK
The PHONES output appears on a 3-pole 1/4 jack, suitable for headphones with an
impedance of 200
W
or higher.
METERBRIDGE
A full width Meterbridge provides continuous monitoring of all Inputs, Groups and
Mix L/R signals on three-colour bargraph meters. All the meters are peak reading.
Normally the Left and Right meters show the level of the Mix Left and Right outputs.
If any PFL or AFL switch is activated the meters are switched to display the level of the
selected PFL or AFL signal.
Note that 0 on the bargraph scale corresponds to a n4dBu.
