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.

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 controllers, 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 controls, amplifiers, and communications gear. Be sure to include necessary electrical boxes, structured wiring enclosures, telephone lines, rough-in brackets, patch cords, power supplies, etc.

A2 INSTALLATION MANUAL

Chapter 3: Connections

The A2 has several rear panel connections so it is important to label all cables and wires correctly. Label all input/ output cable and speaker wires with their destination or source. This will save time during installation and any future upgrades to the system.

Use high quality line level RCA connector type cables for source connections to ensure the lowest possible noise and best sound performance. For most applications use 16AWG 2 conductor speaker cable. For wiring runs longer than 80 ft. it is recommended to use 14AWG 2 conductor speaker cable. The A2's high quality, gold plated 5-way binding post will accommodate speaker cabling sizes up to 12AWG. Attaching banana plugs will enable the connection of larger cable sizes. A 3.5mm mono interconnect cable may be used for amplifier and systems triggering.

Line Level Audio Inputs

Connect the zones by inserting the RCA connectors into the dedicated direct input jack on each channel.

E L A N H O M E S Y S T E M S

Line Ouputs

A stereo or monaural audio signal connected to the A2’s main LINE INPUT is routed to the A2’s RCA Line Outputs. 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 amplier channels. Examples of both these applications are shown in the Chapter 2.

Line audio outputs enable connection of additional amplifiers to allow further system expansion. Use high quality RCA interconnect cables to ensure low noise and great sound. The A2 Line Outputs are buffered, a maximum of four amplifiers may be 'daisy-chained' to each Line Outputs.

Speaker Binding Post

The A2 is equipped with gold plated, 5-way speaker binding posts. This allows five methods of speaker wire termination: bare wire, spade lug, pin, single banana and dual banana plug. Label all speaker wires with their destination to ensure easy configuration. To attach speaker wires use the following method:

1. Carefully split the speaker wire insulation at least two inches.

2. Strip 1/2 inch of the insulation from the speaker wire conductor exposing the bare wire.

3.Twist the wire strands of each conductor, if using banana plugs, attach wire to banana plug observing polarity.

4. If using banana plug; insert plug ends into binding post observing correct polarity. If using the bare wire method; loosen red and black binding post caps and insert the bare wire through the hole in the post. Tighten the knob until the wire is securely clamped.

CAUTION! Speaker Wire connections must be made with the amplifier OFF!

Triggers

A REMOTE TRIGGER IN port allows all channels to turn on or mute simultaneously. The REMOTE TRIGGER INPUT can receive 5-24 Volts AC or DC. The 12 Volt DC REMOTE TRIGGER OUT can be used to turn on other equipment, additional A6s 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 SYSTEM TRIGGER IN port using a 3.5mm mono interconnect cable. Examples of triggering sources include an ELAN MultiZone Controller’s SYSTEM TRIGGER OUT or REMOTE OUT, an A/V receiver’s switched outlet connected to a power supply, or a +12VDC TRIGGER OUT from another ELAN amplifier.

Chapter 4: Operations & Settings

Setting Channel Levels

The A2 features independent Level Adjustment Potentiometers for each of its two 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 potentiometer clockwise increases the level, while turning it counterclockwise decreases 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 longer present. Follow this procedure for each channel.

The A2 requires one rack space, ensure that one rack space above and below the A6 is left open for proper ventilation. To install the A2 into a standard 19” equipment rack:

1. Slide the rack mount kit onto the A2 chassis from the front as shown in Figure B-1.

Figure B-1

2. Ensure that the unit is flush with the front of the mounting kit. Install each of the eight screws (included) through the side mounting flanges into the holes in the sides of the unit as shown in Figure B-2. Hand tighten screws! Over-tightening could cause damage to the A2 Amplifier.
