Audio input

For models P/2 DA8 A and P/2 DA12 A, use a female 3.5 mm mini Tip Ring Sleeve (TRS) connector to provide an unbalanced audio input. Switch off power to the distribution amplifier and

audio source. Connect the audio source	INPUT
to the audio input socket on the rear	Audio Input
panel of the distribution amplifier.

Wiring for the TRS connector is shown in the figure below.

Figure 2-7 — Audio output connections

The audio outputs can be balanced or unbalanced depending on the wiring (see figure 2-8 on the next page). The length of exposed wires in the captive screw connector is critical (see the note and caution on the next page).

NBalanced output wiring produces a +6 dB gain. Unbalanced output wiring produces 0 dB gain.
