Power Control Connections

The ModelA-2000 features a built-in remote turn-on system that will auto-

matically switch the amplifier on when a connected device in the system is

switched on.

Remote Turn-On Using Products EquippedWith a Low

Voltage Trigger Jack

Press the front panel power switch on the amplifier so that it is in the ON

position.Then,using an accessory cable with a 3.5mm mono mini-plug on

each end,connect the trigger-output jack on the rear of the source device to

the trigger input jack on the back panel of the amplifier.When these con-

nections are made, the amplifier will automatically turn on whenever the

triggering device is turned on.

Remote Turn on Using ExternalAC to DC Power Converter

If your processor or receiver does not have a dedicated trigger jack,it is still

possible to activate the unit for automatic turn on when a Switched Outlet

is available on the rear of the source device.To control the amplifier in this

fashion you will need a small AC to DC power converter,capable of deliver-

ing a 6 to 12 volt DC signal.The DC voltage should terminate in a standard

3.5mm type mini plug.This type of converter may be obtained as a Power

Adapterfrommanyelectronicsretailers,ormaybeobtainedatRadioShack

stores as catalog number 273-1758.

When installing, plug theAC adapter into a switched outlet that will be acti-

vatedwhenyouwishtohavetheamplifierturnon.Thismaybetheswitched

outlet at the rear of an AC receiver or other audio equipment. Connect the

3.5mm mini-plug from the adapter to the trigger-input jack on the back

panel of the amplifier.Press the Main Power Switch on the front panel of the

amplifier in so that it is in the ON position.The amplifier will now turn on

and off automatically,based on the status of the controlling device.

Power Connection

Once all audio and system connections have been made, connect the sup-

plied power cord (or an equivalent cord of equal or heavier gauge) to the

amplifier first, and then connect it to an AC power source. Please make

certain that the amplifier is turned off and that the device connected to the

remote trigger input is off when connecting the power cord and plugging

it into an AC outlet.

CAUTION: Do not plug the amplifier directly into the "Switched

Accessory" outlet of another device! These outlets are intended for

use with low current draw products, such as tuners, CD players or

cassette decks. These outlets cannot safely supply the high current

required by a power amplifier like the A-2000. Using switched outlets

like these for a power amplifier poses a significant safety hazard.

IMPORTANT NOTE: It is also not recommended that you connect

other power amplifiers or products with a high current draw, to the

same AC power circuit as the amplifier, unless they are used with the

remote power turn on and some sort of power on sequencing system.

The simultaneous turn-on of multiple amplifiers on the same circuit

may cause circuit breakers to trip, due to the high current draw.

Amplifier Operation

After all connections have been made you are ready for listening.First,with

the processor's volume control all the way down,turn on the source compo-

nents and processor in your system.It is always a good idea to turn on your

amplifier LAST.This avoids the possibility of any turn on pops or transients

fromotherequipmentbeingamplifiedandsenttoyourspeakerswherethey

may cause damage.Be sure to always start with a low volume level on your

controller or preamp to avoid damage to your speakers.

Manual On

Simply press in the front panel power switch until the light is illuminated.

is applied to the speakers. This is intentional, and protects your speakers

from damage while the amplifier stabilizes.You may also hear a relay click

during start up. This is also normal. To turn the unit off, switch the power

switch to the off position.

Output Settings

All volume and level adjustments are made at your preamp, controller or

surroundprocessor.Toassurepropersoundfieldimaging,youshouldre-set

for the first time.The circuitry in your new amplifier may be different from

your previous one,and checking the output levels will make certain that the

processor,amplifier and speakers are properly matched.

Care and Maintenance

Cleaning

If the unit becomes dirty, wipe it with a clean, soft, dry cloth. If necessary,

first wipe the surface with a soft cloth slightly dampened with mild soapy

water,then with a fresh cloth slightly dampened with clean water.Wipe dry

immediately with a dry cloth.NEVER use benzene,thinner, alcohol or any

othervolatilecleaningagent.Donotuseabrasivecleaners,astheymaydam-

agents,or any aerosol product near the unit.

When You Are Away

If you will not be using your home theater system for an extended period

of time, it is always a good idea to disconnect all associated units from the

AC wall current.
