TL Audio 5050 - Manual (Page 7)

3. INSTALLATION
3.1 AC Mains Supply.
The unit 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 5050 is set for the
correct mains voltage. The unit is internally set for 110-120V 60Hz or 220-
240V 50Hz operation, and should only be changed by an authorised service
centre. The mains fuse required is 20mm anti-surge, 1AT rated at 250V. If it is
ever necessary to replace the fuse, only the same type and rating must be
used. The power consumption of the equipment is 20VA.
Warning: attempted operation on the wrong voltage setting, or with an
incorrect fuse, will invalidate the warranty.
3.2
Audio Operating Level.
The 5050 is equipped with inputs and outputs suitable for connection to a wide
variety of other audio equipment. The line level input is via a TRS jack socket,
and will support both balanced and unbalanced operation when correctly
wired. The output is also a TRS jack socket and will support both balanced
and unbalanced operation.
3.3 Microphone
Input.
The microphone input is via 3 pin female XLR connector, suitable for balanced
or unbalanced microphones. The mating connector should be appropriately
wired as follows for balanced or unbalanced operation:
Balanced inputs:
- Pin 1 = Ground (screen).
- Pin 2 = Signal Phase (also known as “+” or “hot”).
