Connector wiring
The amplifier 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, while the standard wiring for 3-pole jack plug connectors is tip hot (+ve) and ring cold (-ve) as
shown below.

Some signal sources such as keyboards, acoustic guitars with on-board electronics, and some
microphones commonly provide only an unbalanced output on a 2-pole jack connector. The Milan
loudspeaker 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 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 a Milan input channel via either the XLR connector or
jack connector. In either case wire the connectors as follows:
