TL Audio C-1 - Manual (Page 9)

- Pin 2 = Signal Phase (“+” or “hot”),
- Pin 3 = Signal Non-Phase (“-” or “cold”).
If an unbalanced output is required, pins 1 and 3 should both be connected to ground.
Nominal Output Level.
A switch on the rear panel allows the output to be matched to equipment at a nominal
operating level of +4dBu or -10dBu. Most professional equipment requires +4dBu
(approximately 1.2V rms), but some small mixing consoles, portable tape recorders
or domestic audio equipment require -10dBu (approximately 225mV rms). The
switch should be set to the position which results in the best signal to noise ratio,
whilst preserving sufficient headroom.
Unbalanced Outputs.
An unbalanced line output is provided for each channel, on a 0.25” mono jack socket.
- Tip = Signal Phase (“+” or “hot”).
- Screen = Ground.
Ventilation.
The unit generates a small amount of heat internally. This heat should be allowed to
dissipate by convection through the grill in the front panel, which must not be
obstructed. Do not locate the unit where it will be subject to external heating, for
example in the hot air flow from a power amplifier, or on a radiator.
The compressor may be free standing, or mounted in a standard 19” rack.
Rear Panel.
The rear panel connectors are identified in fig.3.
