INSTALLATION & CONFIGURATION

Installation and Configuration

SAFETY NOTE: When making connections

between any source components such

as AV receivers, surround processors or

multiroom controllers and the PA 4000,

or when making any connections to

speakers, be certain that both the source

device and the PA 4000 are turned off.To

ensure that there will be no unwanted

signal transients that can damage equip-

ment 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 4000 features a built-in remote turn-on

system that will automatically turn on any of

the amplifier pairs in a number of 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. The PA 4000 may also be controlled

via optional remote room keypads.

Note that when the unit is operated in the

standard, four-output mode, each of the chan-

nel pairs may be operated by the same trigger

method, or they may be turned on via different

methods.

Manual Operation

To operate the PA 4000 manually, with power

on/off controlled by the front-panel

Power

Switch

1

, place the

Power Control Mode

Switch

·

for any of the channels at the far

right, under the phrase “ON/KEYPAD”.When

the switch is in this position, simply press the

Power Switch

1

to turn the unit on or off.

Remote Turn-On From an External Device

Using the Low-Voltage Trigger

To configure the PA 4000 so that any 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 far left position,

so that the switch is under the phrase

“AC/DC TRIGGER”.

2a.To trigger the amplifier from a device such

as a preamp surround processor or multi-

room controller with a built-in trigger jack,

connect one end of a cable with a 3.5mm

mono mini-plug to the

Trigger Jack

fi

on

the PA 4000. Connect the other end to a

matching jack on the device that will pro-

vide a 3-volt to 30-volt signal 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 12 volts DC, and make cer-

tain that one of the “tips” provided with the

unit is a 3.5mm miniplug. Plug the trans-

former end of the converter into the

switched AC output on the source product,

and connect the 3.5mm miniplug to the

Trigger Jack

fi

.

NOTE:

When connections are made to any of

the PA 4000’s trigger jacks, make certain that

the plugs are wired with the positive connec-

tion to the plug’s tip and the negative connec-

tion to the plug’s ring/sleeve.

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 source control unit providing the

power is turned on, the PA 4000 will automati-

cally turn on. When the source unit is turned

off, the PA 4000 will return to the Standby

mode after 10 to 15 minutes.

Remote Turn-On Using Music Sense

To configure the PA 4000 so that any of the

channel pairs turn on automatically when the

amplifier is receiving an audio signal, follow

these steps:

1. Connect the audio input as normal to the

audio

Input Jacks

/›

.

2. For each channel pair that you wish to con-

trol using an incoming audio signal, slide the


·

to the

center position so that the switch is over the

words “MUSIC SENSE”.

3. Press the

Power Switch

1

in so that it is

engaged, and note that the

Standby

Indicator

3

will light for the channel pair

selected for trigger control operation.

In this configuration, the PA 4000 will automat-

ically turn on whenever it is receiving an audio

input signal. The unit will return to the Standby

mode 10 to 15 minutes after the audio signal

stops.

NOTE:

When the PA 4000 is used in the

Bridged mode, use the

Power Control Mode

Switch

·

marked “CH1” or “CH3” for Bridge

1 or Bridge 2 configuration, respectively, to

make the settings for the desired turn-on mode.

Keypad Control

The PA 4000 may also be turned on or off,

and the volume level to any of the channels

controlled using optional compatible remote

keypads.To use the keypads, follow the instruc-

tions supplied with them, and configure the

PA 4000 using the following steps:

1. Connect the remote room keypads to the

Keypad In Jacks

fl

for the channel pairs

that will be controlled. When the unit is

being operated in a bridged mode, connect

the keypads to either the CH1 or CH3 jack,

as appropriate.

2. Place the


·

for the channel pairs to be controlled

remotely in the far right position, under the

words “ON/KEYPAD”.

3. Press the

Power Switch

1

in so that it is

engaged and note that the Standby Indicator

will light for the channel pairs selected for

keypad control operation.

4. The unit will turn on or off in response to

commands made via the remote control

keypads.
