Connecting Speakers in Bridge Mode
In Bridge Mode, both channels in a Zone are connected to a single speaker, via the positive ("+") pins for both output
channels (labeled "BTL", as shown in FIG. 9):

When connecting a speaker to a "bridged" input, verify that the Stereo/Bridge
(SE/BTL) mode switch for the associated Zone (see FIG. 6 on page 7) is set to "BTL".

Bridged Output Mode
In Bridge Mode, one speaker connects
L/R Bridged
to the "+" pins for each Zone

USE CLASS 2
WIRING
If incorrect wiring is used there is a risk of electrical shock and a fire hazard.
