- Pin 3 = Signal Non-Phase (“-” or “cold”).
Unbalanced inputs:
- Pin 1 = Ground (screen)
- Pin 2 = Signal Phase (“+” or “hot”).
- Pin 3 = Signal Ground.
3.4 Line Input.
The line level input is via a TRS jack socket, suitable for balanced or
unbalanced line sources at a nominal level of -10dBu or +4dBu. The mating
connector should be appropriately wired as follows for balanced or unbalanced
operation:
Balanced inputs:
- Screen = Ground (screen).
- Tip = Signal Phase (also known as “+” or “hot”).
- Ring = Signal Non-Phase (“-” or “cold”).
Unbalanced inputs:
- Screen = Ground (screen)
- Tip = Signal Phase (“+” or “hot”).
- Ring = Signal Ground
When using unbalanced signals, the signal ground may be obtained by linking
the ring and screen in the jack plug. If this connection is not made, a loss in
level may result.
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.
