Connecting Input Devices in Bridge Mode
In Bridge Mode, input devices connect to the
left
input channels only. Note that left input connectors are white, and are
the odd-numbered channels (CH1, 3, 5, 7, 9, 11, 13 and 15).
There is a direct correlation between the audio inputs and the speaker outputs. For example, a bridged device connected
to the Channel 1 input (CH1) will output on the CH1 (left) and CH2 (right) speaker outputs - see FIG. 6:

Connecting Speakers
All speaker connections must use
Class 2
Wiring.
Speakers connect to the captive-wire output terminals (CH1-CH16) on the rear panel (FIG. 7): t
Each Zone (1-8) consists of two channels (an L/R pair in Stereo Mode), and each Channel (1-16) uses a 2-pin captive-
wire connector to connect to speakers.

When connecting bridged input devices, verify that the Stereo/Bridge (SE/BTL) mode
switch for the Zone is set to "BTL" as shown above (FIG. 6).
All speaker connections must use Class 2 Wiring. Class 2 Wiring is required due to
the fact that power is above 10W per channel under normal operating conditions.
