Power Switch: The function of this switch
depends on the setting selected for each of the
rear Power Control Mode Switches £. If the
Power Control Mode Switch £ is in the On
position, the associated amplifier pair will turn on
when Power 1 is pressed in. If the Power
Control Mode Switch 
£ is in the MUSIC
SENSE position, the associated amplifier pair will
enter Standby when Power 1 is pressed in and
will turn fully on when a signal is present. If the
Power Control Mode Switch £ is in the
AC/DC TRIGGER position, the associated amplifier
pair will enter Standby when Power 1 is
pressed in and will turn fully on when a 3-30 V
signal is present at the Trigger Jack §. For
more information see item 3, page 6.
2
Power Indicators: These indicators will light
when either of the channel pairs is on.
3
Standby Indicators: These indicators will
light when AC mains power is applied to either of
the channel pairs, but when that channel pair is
not currently active. In this condition, the channel
pair associated with the indicator is ready to turn
on when a signal is applied to the Trigger Jack
§ or when there is an audio signal applied to
the Input Jack ¡.
4
Protect Indicators: These indicators will
light when either of the channel pairs is in the
Protect mode. When one of these indicators
lights, turn the unit off immediately and check for
a problem, such as a short in the speaker wiring.

¡ Input Jacks: Connect these jacks to the
left/right output of the AV receiver, preamp, sur-
round processor, multiroom controller or other
source used to feed the PA 2000.
™ Output Jacks: These jacks provide a parallel
feed of the input signal. In systems where more
than one PA 2000 is used, they may be connected
to the Input Jacks of the additional amplifier.
£ Power Control Mode Switch: (One for
each channel pair) This three-position switch
determines how the two amplifier channels asso-
ciated with the switch are turned on:
• When the switch is in the far right position,
under ON, the amplifier will be turned on when
the front panel Power Switch 1 is pressed
in.
• When the switch is in the middle position, over
the words “AC/DC TRIGGER”, the amplifier will
automatically turn on when a 3-volt to 30-volt
signal is applied to the Trigger Jack §.
• When the switch is in the far left position, under
the words “MUSIC SENSE”, the amplifier will
automatically turn on when an audio signal is
present at the Input Jacks ¡ and will auto-
matically turn off 10 to 15 minutes after the
signal is no longer present.
¢ Output Level Trim Controls (One for each
channel pair) These trim controls are used to
adjust the output level for each channel pair.
∞ Bridge/Normal Switch: This switch deter-
mines whether the unit operates in the “Bridged”
condition or in the Normal mode. Please be cer-
tain to disconnect the power from the unit (by
pressing the Power Switch 1 to off) when
operating this switch.
• When the switch is in the right position, over 
the word “NORMAL”, the unit will provide two
output feed pairs for a total of four output
channels.
• When the switch is in the left position, under
the word “BRIDGED”, the unit will function as a
stereo amplifier, with a single high-power out-
put feed into two output channels.
§ Trigger Jack: Connect this jack to the output
of a compatible product capable of feeding 
a 3-volt to 30-volt signal to the jack when ampli-
fier operation is desired. When one of the channel
pairs has the Power Control Mode Switch £
set to the middle, or AC/DC trigger, position, that
channel pair will automatically turn on when the
low-voltage trigger signal is present. To automati-
cally turn all channels on via the trigger, BOTH
Power Control Mode Switches £ should be
set to the trigger position.
¶ Channel 1 Output Speaker Terminals:
Connect these terminals to the speaker pair that
is fed by the Channel 1 amplifier section.
• Channel 2 Output Speaker Terminals:
Connect these terminals to the speaker pair that
is fed by the Channel 2 amplifier section.
NOTE: When the amplifier is operated in the
Bridged configuration, connect the speakers as
shown on Page 8.
ª AC Power Cord Receptacle: Connect the
AC power cord supplied with the unit to this
receptacle, and connect the power cord plug to
an AC outlet.
INSTALLATION & CONFIGURATION
7
SAFETY NOTE: When making connections
between any source components such 
as AV receivers, surround processors or
multiroom controllers and the PA 2000, or
when making any connections to speakers,
be certain that both the source device and
the PA 2000 are turned off. To ensure that
there will be no unwanted signal tran-
sients that can damage equipment or
speakers, it is always best to unplug all
equipment before making any connections.
Modern electronic products often have a
“standby” mode that may be activated
even though the product may appear to be
turned off.
Power Control Connections
The PA 2000 features a built-in remote turn-on
system that will automatically turn on either or
both of the amplifier pairs in one of three ways.
Depending on your specific application, the unit
may be turned on manually using the Power
Switch 
1, or via automatic sensing of either
an input source or a low-voltage trigger signal.
For manual operation, no special installation is
required. For automatic turn-on, follow the
instructions below for the chosen trigger
method.
Note that when the unit is operated in the stan-
dard, two-pair output mode, each of the channel
pairs may be operated by the same trigger
method, or they may be turned on via different
methods.
Remote Turn-On From an External Device
Using the Low-Voltage Trigger
To configure the PA 2000 so that either or both
of the channel pairs turn on automatically in
response to a low-voltage trigger signal, follow
these steps:
1. Place the Power Control Mode Switch
£ for either channel in the center position,
so that the switch is over the words “AC/DC
TRIGGER”.
2a. To trigger the amplifier from a device such as
a preamp surround processor or multiroom
controller with a built-in trigger jack, connect
one end of a cable with a 3.5mm mono
mini-plug to the Trigger Jack § on the
PA 2000. Connect the other end to a match-
ing jack on the device that will provide a 
3-volt to 30-volt signal (AC or DC with the
tip of the plug “positive” +) when the unit is
to be turned on.
or
2b. To trigger the amplifier using the switched
AC accessory outlet on an AV receiver or
other source device, purchase a small AC to
DC power converter, as is typically used to
replace the batteries in portable electronics
devices. Select a model that is capable of
delivering 3 to 30 volts AC or DC, and make
certain that one of the “tips” provided with
the unit is a 3.5mm mini-plug (DC with the
tip of the plug “positive” +). Plug the trans-
former end of the converter into the
switched AC output on the source product,
and connect the 3.5mm mini-plug to the
Trigger Jack §.
3. Press the Power Switch 1 in so that it is
engaged, and note that the Standby
Indicator 
3 will light for the channel pairs
selected for trigger control operation.
When the control unit connected to the Trigger
Jack is turned on and sending a trigger signal, any
PA 2000 amplifier pair whose Power Control
Mode Switch 
£ is in the AC/DC TRIGGER
position will automatically turn on. When the
source unit is turned off and no longer sending a
trigger signal, any amplifier pair whose Power
Control Mode Switch 
£ is in the AC/DC
TRIGGER position will enter Standby.
NOTE: When the PA 2000 is used in the Bridged
mode as a single-pair stereo amplifier, use the
Power Control Mode Switch £ in the area
labeled “BRIDGE/CHANNEL ONE” to make the
settings for the desired turn-on mode.
Remote Turn-On Using Music Sense
To configure the PA 2000 so that either or both
of the channel pairs turn on automatically when
the amplifier is receiving an audio signal, follow
these steps:
• Connect the audio input as normal to the
audio Input Jacks ¡.
• For each channel pair that you wish to control
using an incoming audio signal, slide the
Power Control Mode Switch £ to the far
left so that the switch is under the words
“MUSIC SENSE”.
• Press the Power Switch 1 in so that it is
engaged, and note that the Standby
Indicator 
3 will light for the channel pairs
selected for Music Sense control operation.
In this configuration, the amplifier for any chan-
nel pair selected for Music Sense control opera-
tion will automatically turn on whenever it is
receiving an audio input signal and will return to
the Standby mode 10 to 15 minutes after the
audio signal stops.
NOTE: When the PA 2000 is used in the Bridged
mode as a single-pair stereo amplifier, use the
Power Control Mode Switch £ in the area
labeled “BRIDGE/CHANNEL ONE” to make the
settings for the desired turn-on mode.

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 “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.
