5.2 Input wiring

You can use

⁄

" phone jacks, XLR connectors, or quick connect terminal block

connectors for the input signal with either unbalanced 2-conductor or balanced

3-conductor cables. Use shielded coaxial cable to conduct the signal from the

source (mixer, equalizer, CD player) to the amplifier.

For the

⁄

" phone jack, use a 3-conductor TRS

" phone plug. The tip of the plug carries

the + (hot, non-inverting) side of the signal. The ring carries the – (low, inverting)

side of the signal. The sleeve is ground (see Figure 25).

For the XLR jack, use a male XLR connector. Pin 2 carries the + (hot, non-inverting) side of

the signal. Pin 3 carries the – (low, inverting) side of the signal. Pin 1 is ground (see Figure
