Operation

Normal Operation

Operation of the PA 2000 is simple. In normal
use, there are no controls to adjust once the
installation is complete.
After all connections have been made to the
amplifier's inputs and speaker terminals, and the
AC power cord has been connected, the way in
which the unit turns on is determined by the set-
tings for the Power Control Mode Switches
£. Depending on the settings, as described on
page 7, the amplifier for the channel pair associ-
ated with the Power Control Mode Switch
£ will turn on in one of these three ways:
• When the Power Control Mode Switch £
is set to the right, in the ON position, the
amplifier will turn on when the Power
Switch 1 is pressed in. Press the switch
again to turn the amp off.
• When the Power Control Mode Switch £
is set in the middle, in the "AC/DC TRIGGER"
position, the Power Switch 1 should be
pressed in to place the amplifier in the
Standby mode. It will now turn on automati-
cally when a low-voltage signal is present at
the Trigger Jack §.
• When the Power Control Mode Switch £
is set to the far left, in the "MUSIC SENSE"
position, the Power Switch 1 should be
pressed in to place the amplifier in the
Standby mode. It will now turn on automati-
cally whenever an audio signal is present and
will return to the Standby mode 10 to 15 min-
utes after the audio signal is removed.
As a general rule, it's always a good idea to turn
on your amplifier LAST. This avoids the possibility
of any turn-on pops or transients from other
equipment being amplified and sent to your
speakers where they may cause damage. Always
start with a low volume level on your receiver,
controller or preamp to avoid damage to your
speakers.
You are now ready to enjoy the finest sonic per-
formance available.
SAFETY NOTE: To prevent unintended opera-
tion, remember to turn the unit completely off
when it will not be used for an extended period
of time. This is done by pressing the Power
Switch 1 so that both Standby Indicators
3 turn off. This will prevent the automatic turn-
on circuits from accidentally turning the amplifi-
er on during your absence.

Output Level Adjustment

In normal operation, the source unit controls the
volume for signals fed to the PA 2000. This is
particularly important for surround-sound appli-
cations, as the volume to all channels in a sys-
tem, regardless of the amplifier, should be equal
in order to ensure proper reproduction. In most
cases, the factory volume setting is appropriate
and need not be changed.
However, in some instances it may be necessary
to vary the output level of the PA 2000, either to
match the levels for surround systems, or to set
a fixed volume level for a remote room speaker.
In these cases, the PA 2000's output volume
may be adjusted by turning the Output Level
Trim Control ¢ on the rear panel. When
adjustment is required, turn the knob in either
direction until the desired level is achieved.
When the PA 2000 is operated in the Bridged
configuration, use the Output Level Trim
Control ¢ labeled "VOL. 1" to make adjust-
ments.
NOTE: The Output Level Trim Controls operate
for both speakers in a given channel. You may
adjust the output of one channel pair or the
other, but it is not possible to individually adjust
either the separate left or right channel output
within a given channel pair.
