¡ 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.
