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 settings for the

Power Control Mode

Switches

£

. Depending on the settings, as

described on page 7, the amplifier will turn on

in one of these three ways:

• When the

Power Control Mode Switches

£

are set to the right, in the ON position,

the PA 2000 will turn on when the

Power

Switch

1

is pressed in. Press the switch

again to turn the amp off.

• When the


£

are set in the middle, in the “AC/DC

TRIGGER” position, the

Power Switch

1

should be pressed in to place the PA 2000 in

the Standby mode. The unit will now turn on

automatically when a low-voltage signal is

present at the

Trigger Jack

§

.

• When the


£

are set to the far left, in the “MUSIC

SENSE” position, the

Power Switch

1

should be pressed in to place the PA 2000 in

the Standby mode. The unit will now turn on

automatically whenever an audio signal is

present. The unit will return to the Standby

mode 10 to 15 minutes 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 pos-

sibility 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

performance 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

and noting that the

Standby

Indicator

3

goes out. This will prevent the

automatic turn-on circuits from accidentally

turning the amplifier 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

applications, as the volume to all channels in a

system, regardless of the amplifier, should be

equal in order to ensure proper reproduction. In

most cases, the factory volume setting is appro-

priate 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.
