Connector wiring
The amplifier microphone and line inputs are designed to accept balanced (three conductor)
connections, and it is recommended that this method be used since it offers the best rejection of
noise, hum and radio interference, especially where long cable runs are involved. XLR connectors
should be wired pin 2 hot (positive), pin 3 cold (negative) and pin 1 ground, while the standard
wiring for 3-pole jack plug connectors is tip hot (positive), ring cold (negative) and sleeve ground
as shown below.

Some signal sources such as keyboards, acoustic guitars with on-board electronics commonly
provide only an unbalanced output on a 2-pole jack connector. The Milan loudspeaker line input
can handle these connections without any rewiring since pin 3 (-ve) of the input is automatically
grounded by the jack plug.

If an unbalanced source is to be connected to an input channel via the XLR line input connector,
either 2-pole or 3-pole jack plugs can be used. In both cases pin 3 should be connected to pin 1
(ground) at the XLR as shown here.

Some sources such as mp3 players or CD players commonly provide 2-pole unbalanced phono
connectors, and these can be connected to the Milan line input channel via either the XLR
connector or jack connector. In either case wire the connectors as follows:
