TL Audio 5013 - Manual (Page 8)

3.5 Instrument Input.
A 2-pin (mono) jack plug is required, which should be wired as follows:
- Tip = Signal Phase (“+” or “hot”).
- Screen = Ground.
The instrument input is suitable for direct connection of instruments including
guitars and keyboards. Good quality screened cable should be used,
particularly for microphone or low level sources, to prevent hum or noise
pickup.
3.6 Balanced
Output.
The output is via a balanced, 3 pin male XLR connector. The mating connector
should be wired as follows:
- Pin 1 = Ground (screen).
- Pin 2 = Signal Phase (“+” or “hot”).
- Pin 3 = Signal Non-Phase (“-” or “cold”).
3.7 Unbalanced Output.
An unbalanced line output is provided for each channel, on a 0.25” mono jack
socket.
- Tip = Signal Phase (“+” or “hot”).
- Screen = Ground.
3.8 Mounting.
The equaliser may be free standing, or mounted in a standard 19” rack.
Always ensure that the cooling vents on the front and sides are clear of
obstruction, and do not subject the unit to an external source of heat (by
mounting immediately above a power amplifier, for example). If used free
standing, ensure that the equipment is protected against rain and spillage of
liquid.
