- Screen = Ground.
Unbalanced equipment may be interfaced with the processor insertion point, by wiring
the plugs with ring and screen connected together.
The insertion point is “half normalled”, i.e. a plug inserted into the Send socket will
provide an additional signal output, without breaking the signal flow within the
processor. When a plug is inserted into the Return socket, however, the internal signal
is interrupted and replaced with the insertion return signal.
Output.
The output is via 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”).
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.
