Balanced

The advantage of a balanced cable is its ability to reject external interference. Therefore, it is suitable for handling a small level signal or transferring over long dis- tances. The LR16 provides the following balanced connectors.

	Inputs/outputs	Connectable connectors

	[INPUT 1-16]	XLR-3-12 connector, 3-con-
	[INPUT 1-16]	ductor TRS or 2-conductor

	[STEREO OUT (L, R)]	XLR-3-11 connector

	[GROUP OUT 1 - 4]	2-conductor phone plug

	[PHONES]	3-conductor TRS phone plug
