ELAN HOME A2 INSTALLATION MANUAL SYSTEMS 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.

A2 INSTALLATION MANUAL ELAN HOME SYSTEMS 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.
ELAN HOME A2 INSTALLATION MANUAL SYSTEMS Applications The A2 is specifically designed for multi-speaker applications. Three parallel amplifiers per channel provide high-current drive for high-impact bass performance.
A2 INSTALLATION MANUAL ELAN HOME SYSTEMS 4 Ohm Speakers w/ Volume Controls 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.

ELAN HOME A2 INSTALLATION MANUAL SYSTEMS Multi-Room Stereo Sub-Zones ELAN’s S66A/S86A Integrated Multi-Room Controllers have built-in amplification for six stereo zones as well as six sets of preamp outputs for the addition of sub-zones. The A2 is ideally suited to amplify outdoor subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones as shown in the S66A example below.

ELAN HOME A2 INSTALLATION MANUAL SYSTEMS S128P Stereo Sub-Zones ELAN’s S128P Integrated Multi-Room Controller has variable preamp outputs for eight stereo zones as well as eight sets of fixed preamp outputs for the addition of sub-zones. The A2 has the ability to provide high power to large area such as Great Rooms. Use rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones.

ELAN HOME A2 INSTALLATION MANUAL SYSTEMS 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.
A2 INSTALLATION MANUAL ELAN HOME SYSTEMS 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 amplifier channels. Examples of both these applications are shown in the Chapter 2.
ELAN HOME A2 INSTALLATION MANUAL SYSTEMS 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.
A2 INSTALLATION MANUAL ELAN HOME SYSTEMS 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.
ELAN HOME A2 INSTALLATION MANUAL SYSTEMS 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%.
A2 INSTALLATION MANUAL ELAN HOME SYSTEMS Chapter 5: Troubleshooting Symptom Possible Cause Solution No Audio From One or More Channels 1. Loose/bad speaker cable connec- 1. Check cable ends at binding posts tion and speaker terminals. 2. Break/short in speaker cable 2. Check continuity of each speaker cable using multimeter. If short or open is indicated, check wiring for proper connections. 3. Swap with known good speaker. 3. Speaker is defective 4. Swap with known good patch cable. 4.
ELAN HOME A2 INSTALLATION MANUAL SYSTEMS Symptom Possible Cause Solution Distorted Audio at Normal Volume Levels 1. Input gain set too high 1. Reduce gain to the channel in question. 2. Defective/incompatible speaker 2. (a) Check for physical damage to speaker. (b) Ensure speakers have appropriate power rating for amplifier. (c) Ensure speakers are rated @ 8 Ohm impedance. This amp is compatible with speakers with 8 Ohm impedance or greater. 3. Volume control wired incorrectly 4.

ELAN HOME A2 INSTALLATION MANUAL SYSTEMS Appendix B: Rack Mounting Rack-Mount Bracket When mounting the A2 amplifier in an equipment rack, use the included rack mount brackets for secure mounting and proper ventilation. 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.
