TL Audio EQ-2 - Manual (Page 5)

INSTALLATION
AC Mains Supply.
The equaliser is fitted with an internationally approved 3 pin IEC connector. A
mating socket with power cord and mains plug is supplied. All mains wiring should be
performed by a qualified electrician with all power switched off, and the earth
connection must be used.
Please note that when using this unit with alternate supply voltages (in foreign
countries, for example) the position of the voltage selector switch on the rear of the
unit may need adjusting. 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 setting may be adjusted by inserting a small flat bladed screwdriver
into the slot of the switch, and sliding the switch to the left (for 115V) or to the right
(for 230V).
Alternate supply voltages may also require a different power cable or mains plug. If in
doubt, consult local electrical regulations.
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.
