Mono Audio (local audio) outputs — Connect audio devices, such as an
audio amplifier or powered speakers, to these four or eight 3.5 mm, 5-pole
captive screw connectors. These connectors output the selected unamplified,

The length of the exposed (stripped) portion of the copper wires is
important. The ideal length is 3/16” (5 mm). Longer bare wires can
short together. Shorter bare wires are not as secure in the direct insertion
connectors and could be pulled out.

The audio that is output on this (these) connector(s) is converted from the
tied proprietary TP input signal or the local audio input. This feature allows
you duplicates of the outputs while eliminating the need for extra receivers.

The volume level for each local output can be individually set via the
front panel or serial port control. See chapter 3, “Operation”, chapter 4,
