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 6).
See the
Connecting Input Devices in Bridge Mode section on page 7
for details.
See the
Connecting Speakers section on page 7
for connection details.
The following table provides pinout information for the Speaker Output Terminals
Connecting Speakers in Stereo Mode
Stereo speaker pairs use both output channels (left and right) for each Zone.
Odd
-numbered channels should be used to connect to the
left
speaker.
Even
-numbered channels should be used to connect to the
right
speaker.
The ALR-AMP-8 supports up to eight stereo speaker pairs, each one associated with a Zone (1-8).
FIG. 8 illustrates the wiring connection from both Zone output channels to a stereo speaker pair:
For wiring runs longer than 80 feet, 14-gauge speaker wire is recommended.
