A1240

INSTALLATION MANUAL

1. Introduction

The ELAN A1240 Power Amplifier is designed to pro-
vide a reliable, affordable solution for multi-room audio
systems requiring up to twelve channels of amplifica-
tion. Using proven analog technology, the A1240 adds
advanced features like Audio Sensing, Stereo/Mono
Bus, and Trigger Inputs/Outputs to make it the premier
amplifier in its price range.

Features

• 12 x 40 Watts per Channel @ 8 Ohms

• Stereo/Mono Bus

Any input can be combined or bussed using simple

DIP switches to send audio to any output without the

use of additional patch cables - making setup neat

and easy.

BUS LOOP OUTPUTs allow the bussed

signal to be sent to other amplfiers, A/V receivers,

etc.

• Individual Pair Remote Trigger Inputs

Six +12VDC TRIGGER INPUTS allow each pair of

channels to be activated independently.

• System Trigger In/Out

SYSTEM TRIGGER IN allows all channels of the

amplifier to turn on when a signal is received.

SYSTEM TRIGGER OUT sends a +12VDC pulse

whenever any of the channels of the amplifier are on.

• Audio Loop Outputs

Sends audio signals out from specific A1240 channels

to line level inputs of other devices such as additional

amplifiers or audio processors.

• Individual Channel Level Adjustments

Fine-tune each channel’s level using precision

potentiometers.

• Audio Sense

Allows amplifier channels to mute/un-mute based

upon whether an audio signal is detected.

• Removable Locking Speaker Terminals

Six removable locking connectors allow easy speaker

wire terminations.

Safety Concerns

Use only grounded outlets when powering this product.
Making any modification to the power cord could cause
unsafe operation and will void the manufacturer's war-
ranty.

AC Power Considerations

The A1240 requires 4 Amps of AC current. The
A1240240 (240V version) requires 2 Amps of AC current.
When designing any whole house system using multi-
channel amplifiers, make sure to provide adequate pro-
visions for all electronic equipment to be installed. This
may require additional outlets and/or circuit breakers to
be installed. Consult a licensed electrician in this case.

ALL CONNECTIONS SHOULD BE MADE

WITH THE AMPLIFIER TURNED OFF

AND UNPLUGGED FROM POWER.

DAMAGE CAN OCCUR TO EQUIPMENT

IF IMPROPER CONNECTIONS ARE MADE!

THIS AMPLIFIER IS NOT BRIDGEABLE!

DO NOT TRY TO BRIDGE

OR COMBINE OUTPUTS!

DAMAGE TO THE AMP WILL OCCUR.
