Speaker Connection
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 din-
ing room speakers. While each room will receive
the same feed, the volume may be controlled 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 certain
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 plastic
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 surround
channels of a 7.1 surround-sound system, 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 screwdriv-
er 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 “/–”, 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.
