INSTALLATION
AC Mains Supply.
The equaliser is fitted with an internationally approved 3 pin IEC connector. A
mating socket with power cord is provided with the unit, wired as follows:
Brown: Live.
Blue: Neutral.
Green/Yellow: Earth (Ground).
All mains wiring should be performed by a qualified electrician with all power
switched off, and the earth connection must be used.
Before connecting the unit to the supply, check that the voltage selector switch on the
rear panel is correctly set. The unit may be set for 115V (accepting voltages in the
range 110V to 120V, 60Hz AC), or to 230V (for voltages in the range 220V to 240V,
50Hz AC). The fuse required is 20mm anti-surge, 1AT.
Warning: attempted operation on the wrong voltage setting, or with an
incorrect fuse, will invalidate the warranty.
Audio Inputs.
Each channel has two female, 3 pin XLR connectors, for mic and line sources. Both
are compatible with either balanced or unbalanced signals, when the mating
connectors are appropriately wired:
Balanced inputs:
- Pin 1 = Ground (screen).
- Pin 2 = Signal Phase (“+” or “hot”).
- Pin 3 = Signal Non-Phase (“-” or “cold”).
Unbalanced inputs:
- Pin 1 = Ground (screen)
- Pin 2 = Signal Phase (“+” or “hot”).
- Pin 3 = Signal Ground
