MASTER SECTION
1
PHANTOM POWER
Many professional condenser mics need PHANTOM POWER, which is a method of
sending a powering voltage down the same wires as the mic signal. Press the switch
to enable the +48V power to all of the MIC inputs. The adjacent LED illuminates when
the power is active.
WARNING: TAKE CARE when using unbalanced mics which may be
damaged by the phantom power voltage. Balanced dynamic mics can
normally be used with phantom power switched on (contact your
microphone manufacturer for guidance)
Mics should always be plugged in, and all output faders set to mini-
mum before switching the Phantom Power ON to avoid damage to
external equipment

POWER INDICATOR
This LED lights to show when power is connected to the console.
3
BARGRAPH METERS
The three-colour peak reading BARGRAPH METERS normally show the level of the MIX
RIGHT and MIX LEFT outputs, giving you a constant warning of excessive peaks in the
signal which might cause overloading. Aim to keep the signal just touching the red
segments at peak levels for best performance.
Similarly, if the output level is too low and hardly registering at all on the meters, the
level of background noise may become significant. Take care to set up the input levels
for best performance.
When any PFL switch is pressed, the meters switch to show the selected PFL signal on
both meters, in mono.
4
PLAYBACK
The rotary control sets the level of the 2 Track Tape input, which is routed to the
headphones, monitor outputs and meters. These inputs, on RCA phono connectors are
an ideal way to connect the playback of a tape machine for monitoring.
5
PLAYBACK REPLACES MIX
Press this switch to replace the MIX Left/Right signal at the MIX outputs with the
Playback signal connected to the Left and Right RCA sockets
r
(see also p.22).
6
PLAYBACK PFL
Press this switch to route the Playback signal to the monitor and phones, over-riding
the default monitor/Phones signal. This listening point is before the PB LEVEL control,
so material can be previewed before being routed.
7
MONITOR LEVEL
This control sets the level to the MONITOR LEFT & RIGHT outputs. If headphones are
plugged into the PHONES jack, the headphone level will track the Monitor Level.
8
PHONES LEVEL
This control sets the output level to the Headphone outputs. If headphones are
plugged into the PHNS jack, then the knob sets a comfortable headphone listening
level without affecting the Monitor output levels.
9
AUX MASTERS
Each Aux output has a master output level control and associated AFL switch.
AUX AFLs
Just like the PFL switches on the channels, you can monitor each AUX output by
pressing the AFL switch. This routes the AUX output signal to the MONITOR or
PHONES, replacing the MIX signal. The METERS also switch from the MIX to display
the PFL/AFL signal and the PFL/AFL LED lights to warn that a PFL or AFL switch is
pressed. When you release the switch, the Monitor swaps back to the MIX.
