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. 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 micro-

phone manufacturer for guidance)

Mics should always be plugged in, and all output faders

set to minimum before switching the Phantom Power

ON to avoid damage to external equipment

2 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 follow the

Monitor selection to 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 amber segments at peak lev-

els 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 2TK LEVEL

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 con-

nectors are an ideal to connect the playback of a tape machine for monitoring.

5 MIX/SUB

When this switch is released the meters and headphones monitor the Mix sig-

nal. Alternatively, pressing the switch selects the SUB mix as the monitor source.

6 2TK

Pressing the 2TK switch selects the 2TK input as the monitor source, instead

of the MIX or SUB signal (see MIX/SUB above).

7 MONITOR & PHONES LEVEL

This control sets the output level to the MONITOR LEFT & RIGHT outputs. If

HEADPHONES are plugged into the PHNS jack the Monitor outputs are cut off,

and the knob then sets the headphone listening level. When the PHONES are

unplugged the Monitor output is restored.

8 AUX MASTERS

Each Aux output has a master output level control and associated AFL switch.
