8 CHANNEL CONFIGURATION
Channel Configuration and Speaker Connections
Two-Pair Output
For use in multiroom applications, the PA 2000
may be used to send the same signal feed to
two separate locations, such as living room and
dining room speakers.While each room will
receive the same feed, the volume may be con-
trolled by using the channel Output Level
Trim Controls ¢ or optional in-wall volume
controls.
The PA 2000 is factory-shipped to operate in
this configuration,but it is always a good idea
to double-check the switch setting to make cer-
tain that it is correct. For two-pair output, the
Bridge/Normal Switch ∞ should be set so
that the switch is on the right side, over the
word “NORMAL”.To ensure that the switch set-
ting is not changed, make certain that the plas-
tic switch guard is installed once the proper
setting is made.
To connect speakers when the PA 2000 is used
in the two-pair output mode, connect one pair
of speakers to the Channel 1 Output
Speaker Terminals ¶, and the other pair to
the Channel 2 Output Speaker Terminals
•. (See Figure 1.)
Figure 1
One-Pair Output (Bridged Operation)
The PA 2000 is a bridgeable amplifier, which
means that the two pairs of medium-powered
amplifiers may also be combined, or “bridged”,
to form a higher-powered stereo amplifier with
a single pair of outputs.This type of operation
is suitable for use in powering the rear sur-
round channels of a 7.1 surround-sound sys-
tem, or for general use as a high-quality, high-
power stereo amplifier for a main listening
room or remote room applications.
To configure the PA 2000 for use as a single-
pair stereo amplifier, follow these steps:
• Disconnect the power from the unit.
• Locate the Bridge/Normal Switch ∞ on
the rear panel, and use a #1 Phillips screw-
driver to carefully remove the screws on
either side of the plastic switch guard.
Remove the plastic guard and set it aside
with the screws.
• Slide the switch to the left so that it is under
the word “BRIDGE”.
•Replace the plastic switch guard so that it
secures the switch in the desired position.
• Replace the two screws to secure the plastic
guard.
To connect speakers when the PA 2000 is used
as a stereo amplifier, an alternative connection
method is used.As shown in Figure 2, connect
the speakers to the terminals shown
on the rear panel as “BRIDGE +/–”,with the
connections made vertically, as opposed to the
horizontally oriented connections used in two-
pair output use. Note that the negative, or “–”,
terminal used for bridged operation is normally
marked as “+” for use in two-pair use. For
bridged operation,please observe the Bridge
markings, not the markings used for the Ch. 2
output.
