unbalanced line level input, tie (short) the (G) and (–) terminals together with an insulated jumper
wire.
7. Line In
The Line In connector is useful for receiving a -6dBV mono unbalanced line level signal from a
playback system such as a CD player.
8. Line Out
Line Out connector is useful for providing unbalanced line level signal to another amplifier or other
external device.
