MASTER SECTION (EFX)

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 volt-

age. 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 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 MASTER FADERS

The MASTER FADERS set the final level of the MIX outputs, and separate faders are provided for each output. These should normally be set close to the ‘0’ mark if the input GAIN settings have been correctly set, to give maximum travel on the faders for smoothest control.

4 MIX OUTPUTS, INSERTS & MONO OUTPUT

The Mix LEFT and RIGHT outputs are sent from the XLR sockets as imped- ance-balanced signals. The Mix INSERT points are on 3-pole ‘A’ gauge jacks and are unbalanced. The MONO OUTPUT (EFX only) caries a mono sum of the left and right mix signals on a 3-pole ‘A’ gauge jack, the output is impedance-balanced.

5 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 ex- cessive peaks in the signal which might cause overloading. Aim to keep the signal within the amber 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; the PFL ACTIVE LED also lights.
