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.

Multi-Room Applications
The A1240 is specifically designed for multi-room appli-
cations. Virtually every feature was selected to enhance
the multi-room experience and simplify the multi-room
installation. With Buffered Loop Outputs, Bus Modes,
and advanced Trigger options, the A1240 can be cus-
tomized for even the most complex systems.
Independent Stereo Zones
The A1240 is designed to easily power six independent
stereo zones without any special setup procedures.
This is the standard configuration for most multi-zone

A1240 INSTALLATION MANUAL
The term BUS is defined as the ability to route a signal
from one place to another. Traditional busing is done
using audio patch cables to route these signals. The use
of Bus Switches, such as the ones on the A1240, elimi-
nates the need for additional patch cables and adds to
the flexibility of signal routing.
Bus Input & Bus Loop Ouput
A stereo or monaural audio signal connected to the
A1240’s main BUS INPUT can be routed to any of the
A1240’s twelve channels. This feature is excellent for
standalone distributed audio systems where one source
(i.e. an A/V Receiver) is providing audio to the entire
home, and also for ELAN multi-room applications where
a zone’s audio signal needs to be routed to multiple
amplifier channels. Examples of both these applications
are shown on the following pages.
3. Bussing
The BUS LOOP OUTPUT is an easy way to add on ad-
ditional rooms of music by connecting them to a second
(or 3rd, or 4th) A1240.
Bus DIP Switch Settings
There are independent BUS DIP switches for each chan-
nel on the A1240. The DIP switches labeled BUS L (Left)
and BUS R (Right) determine whether the signal con-
nected to the Left and Right channels of the BUS INPUT
will be routed to that channel. Any channel that has its
BUS switches in the ON (DIP switch set to the left) posi-
tion will receive the audio signal from the BUS INPUT.

A1240 INSTALLATION MANUAL
Direct Input Bussing
There are independent Direct Input Bus DIP switches for each channel on the A1240. These
DIP switches are located directly below the BUS L/R DIP switches and are labeled 1-12.
Their purpose is to allow the creation of summed mono signals without having to use addi-
tional patch cables. For example, if A1240 Input #1 is being fed a monaural signal, and Input
#2 needs to receive that same signal, slide the DIP switch labeled “1” to the left, (ON) position
for both channels 1 and 2. Direct Input Bussing is for channel pairs only (1/2, 3/4, 5/6, 7/8,
9/10, 11/12). In other words, Channel 3 can only be sent to Channel 4, and Channel 4 can only
be sent to Channel 3.

DIP Switch Settings
The four DIP switches correspond (from top to bottom) to Bus Left, Bus Right, Direct
Input Left, and Direct Input Right. Flip the switch to the left to enable the setting, to
the right to disable it. Only one setting should be enabled (set to the left position) at
a time. Carefully review the diagrams below before setting DIP switches.

4. Triggers
Each channel pair of the A1240 has its own Remote
Turn On/Muting circuit (TRIGGER INPUTS 1/2-11/12).
Individual channel pairs can be muted or un-muted inde-
pendently of any others. A SYSTEM TRIGGER IN port
allows all channels to turn on or mute simultaneously.
All TRIGGER INPUTS can receive 5-24 Volts AC or DC.
The 12 Volt DC SYSTEM TRIGGER OUT can be used
to turn on other equipment, additional A1240s or other
amplifiers, or to perform automated functions desired by
the user. Use 3.5mm mono interconnect cables to make
Trigger connections.
SYSTEM TRIGGER IN
To mute/un-mute all channels simultaneously, connect a
system-wide 5-24 Volt DC triggering source to the SYS-
TEM TRIGGER IN port using a 3.5mm mono intercon-
nect cable. Examples of triggering sources include an
ELAN Multi-Zone Controller’s SYSTEM TRIGGER OUT or
REMOTE OUT, an A/V receiver’s switched outlet con-
nected to a power supply, or a +12VDC TRIGGER OUT
from another ELAN amplifier.
SYSTEM TRIGGER OUT
Whenever the A1240 is powered On an any channel is
On, the SYSTEM TRIGGER OUT becomes active. This
output sends a +12VDC 100mA signal to other devices
with a Trigger Input. Examples of proper usage of
the SYSTEM TRIGGER OUT include muting/un-mut-
ing other amplifiers, triggering the switched outlets of
a Z•Power Controller, or triggering automated events
using ELAN®Sense Sensors and VIA! SR-1 or VIA!2-SS1
devices.
TRIGGER INPUTS 1/2-11/12
To Mute/Un-Mute specific pairs of channels, a zone-
specific triggering source must be used. Any 5-24 Volt
DC source may be used to trigger these specific inputs.
This application gives additional control in advanced
systems. Examples include: ZONE TRIGGER OUT-
PUTs from an ELAN Multi-Room Controller, multiple A/V
receivers triggering separate A1240 inputs, or outboard
sensors located in certain areas to trigger specific in-
puts of the A1240.

5. Setup
Setting Channel Levels
The A1240 features independent Level Adjustment Pots
for each of its twelve channels. Use a small Phillips
screwdriver to independently adjust each channel of the
amplifier for the specific speakers and environmental
conditions of the area it is powering. Turning the pot
clockwise increases the level, while turning it counter-
clockwise decreses the level. Factory default is 50%.
Set the levels by first lowering them all the way down,
then raise the volume of any keypads or volume controls
to maximum. Slowly increase the level of the channel
being adjusted by turning the potentiometer clockwise
until the channel begins to distort, then reduce the level
slightly (turn counter-clockwise) until distortion is no lon-
ger present. Follow this procedure for each channel.

Audio Sense
When Audio Sense is enabled (AUDIO SENSE button de-
pressed), the presence of audio on a particular line-level
audio input will automatically un-mute the corresponding
speaker-level audio output. Once the audio output is ac-
tive, the SYSTEM TRIGGER OUT will also become
active. If Audio Sense is enabled, it will mute a chan-
nel once an audio signal is absent for a period of two
minutes.
