Connecting Speakers
All speaker connections must use Class 2 Wiring.
NOTE: 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.
Speakers connect to the captive-wire output terminals (CH1-CH16) on the rear panel (FIG. 7): t

Speaker (Output) Terminals (16 total, L/R pairs for eight stereo outputs)
FIG. 7
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.
NOTE: For wiring runs longer than 80 feet, 14-gauge speaker wire is recommended.
Speaker Output Connectors
The speaker output connectors consist of two 16 pin captive-wire terminals; each of the output terminals having a
"+" and "- " terminal.
The label "BTL" on each speaker pair points to the pins that are used when connecting a single speaker to an input in Bridge Mode
(see SE/BTL (Stereo/Bridge Mode) Switches (1-8) on page 10).
See the Connecting Input Devices in Bridge Mode section on page 11 for details.
See the Connecting Speakers section on page 12 for connection details.
