A2 INSTALLATION MANUAL
Chapter 1: Introduction
Boasting 150 Watts per channel at 2 ohms, the ELAN A2 Power Amplifier is designed and engineered to be the
definitive cornerstone component for any high-power application. The A2’s discrete output circuitry easily powers up
to three pairs of 8 ohm speakers simultaneously, eliminating the need for speaker selector boxes or load protection
devices. Buffered loop outputs provide easy connection of additional amplifiers. Using proven analog technology,
the A2 adds advanced features like Trigger Inputs/Outputs to make it the premier two channel amplifier in its price
range.
A2 Features
2 x 60 Watts per Channel @ 8 Ohms
2 x 100 Watts per Channel @ 4 Ohms
2 x 150 Watts per Channel @ 2 Ohms
Buffered Line Outputs
• allow the signal to be sent to other A2 amplfiers, A/V receivers, etc.
System Trigger In/Out
• SYSTEM TRIGGER IN allows all channels of the amplifier to UNMUTE
when a signal is received.
• SYSTEM TRIGGER OUT sends a +12VDC pulse whenever any of the
channels of the amplifier are UNMUTED.
Individual Channel Level Adjustment
• Fine-tune each channel’s level using precision potentiometers.
5-Way Speaker Binding Post
• The A2 is equipped with gold plated, 5-way speaker binding posts.
This allows for five methods of speaker wire termination: bare wire,
spade lug, pin, single banana and dual banana plug.
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 warranty.
AC Power Considerations
The A2 requires 3.7 Amps of AC current. When designing any whole house system using multichannel amplifiers,
make sure to provide adequate provisions for all electronic equipment to be installed. This may require additional
outlets and/or circuit breakers tobe 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 TR TO BRIDGE
OR COMBINE OUTPUTS!
DAMAGE TO THE AMP WILL OCCUR.

Chapter 2. System Design & Applications
System Design
The first step to a good design is to map the system. It is advisable to mark up a copy of the house floor plan with
speaker, keypad, touch panel, volume control, and equipment locations etc. Make sure that all locations are decided
upon before pre-wiring commences so that all necessary wiring and installation hardware is in place. This unit will
be interfacing with other components such as multi-room controllers, source components, communications control-
lers, serial controllers, and user interfaces, so it is essential that ALL system components are accounted for prior to
the pre-wire stage.
Secondly, make a detailed list of all components. Include source equipment, keypads, touch panels, volume con-
trols, amplifiers, and communications gear. Be sure to include necessary electrical boxes, structured wiring enclo-
sures, telephone lines, rough-in brackets, patch cords, power supplies, etc.

A2 INSTALLATION MANUAL
Applications
The A2 is specifically designed for multi-speaker applications. Three parallel amplifiers per channel provide high-cur-
rent drive for high-impact bass performance. The A2 also features three pair of gold-plated 5-way binding posts for
easy connection of multiple speaker pairs, a Remote Audio Mute Circuit that eliminates any “noise” that might come
through the speakers when the source components are not in use and 'installer-friendly' Channel Level Adjustments
which are easily accessible via the front panel.
4 Ohm Speakers
Since the A2 Power Amplifier is stable down to a 2 ohm load, it can handle multiple speaker pairs wired in
parallel. The following diagrams show the maximum number of speaker pairs that can be connected to the A2.
