in a loss of level and/or increased noise. Good quality screened cable should be used,
to prevent hum or noise pickup.
Outputs.
The outputs are via balanced, 3 pin male XLR connectors. The mating connectors
should be wired as follows:
- Pin 1 = Ground (screen),
- 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.
Ventilation.
The unit generates a moderate amount of heat internally, which should be allowed to
dissipate by convection through the grills in the sides and 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, or in direct
sunlight.
The unit may be free standing, or mounted in a standard 19” rack.
