Ring = Ground.
The equipment utilizes good quality screened cable, particularly for microphone or low
level sources, So that hum or noise cannot be picked up.
Refer to Figure 2 for rear panel connector identification.
3.4 Instrument Inputs.
-
On the front panel, each channel has a high impedance (1Mohm) 0.25" instrument
jack socket (see Figure 1). A 2 pin (mono) jack plug is required, which should be wired as
the following way:
- Tip = Signal Phase ("+" or "hot"),
- Screen = Ground.
3.5 Balanced Line Outputs.
-
On the rear panel, the line outputs are via 3 pin TRS jack sockets and may be
configured for balanced or unbalanced connection. Balanced operation is always
preferable to maintain maximum headroom and signal to noise ratio, but can only be
used if the following equipment is also capable of balanced operation:
Balanced outputs:
- Screen = Ground,
- Tip = Signal Phase ("+" or "hot"),
- Ring = Signal Non-Phase ("-" or "cold").
Unbalanced outputs:
- Screen = Ground,
- Tip = Signal Phase ("+" or "hot"),
- Ring = Ground.
3.6 Nominal Operating Level.
-
A switch on the rear panel allows the line inputs and outputs 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 or
portable tape recorders require -10dBu (approximately 225mV rms). If the operating
level is not known, the switch should be set to the position which results in the best signal
to noise ratio, whilst preserving sufficient headroom.
