A12 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 A12 INSTALLATION MANUAL SYSTEMS Multi-Room Applications The A12 is specifically designed for multi-room applications. 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 A12 can be customized for even the most complex systems. Independent Stereo Zones The A12 is designed to easily power six independent stereo zones without any special setup procedures.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Two Room Stereo Zone By using the A12’s Buffered Loop Outputs, an additional pair of speakers can be added to a zone. In this example, both pairs of speakers will ramp volume up and down simultaneously.
ELAN HOME SYSTEMS A12 INSTALLATION MANUAL Stereo Zone w/ Mono Sub-Zone Use the Loop Out Jacks and an RCA ‘Y’ cable to create mono sub-zones within a stereo zone. This application is perfect for large rooms with smaller rooms attached such as a Master Bedroom/Master Bath or Kitchen/Laundry Room.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS S66A Sub-Zones ELAN’s S66A Integrated Multi-Room Controller has built-in amplification for six stereo zones as well as six sets of preamp outputs for the addition of sub-zones. The A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS S86A Sub-Zones ELAN’s S86A Integrated Multi-Room Controller has built-in amplification for six stereo zones as well as six sets of preamp outputs for the addition of sub-zones. The A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS S128P 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 A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS Chapter 3: Connections Bussing 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 A12, eliminates the need for additional patch cables and adds to the flexibility of signal routing.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Stand-Alone System Examples Stereo Bussing The example below shows the preamp output of an A/V Receiver being distributed throughout the home in stereo using the BUS INPUT of the A12. A second A12 can be added for six additional pairs of speakers via the Bus Loop Outputs. Up to four A12s can be linked via LOOP OUTPUTs.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS Mono Bussing This example is a variation of the previous one. The first A12’s Bus Loop Outputs are 'Y’d' to create a summed L/R signal, allowing the addition of twelve monaurally-wired speakers.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS ELAN Multi-Room System Examples ‘Bussing’ the audio from a Zone Output of an ELAN multi-room controller is an easy way to create a large ‘wide coverage zone’ without using any additional patch cables. The following diagrams show examples of how both stereo and mono ‘wide coverage zones’ may be configured.

A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Direct Input Bussing There are independent Direct Input Bus DIP switches for each channel on the A12. 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 additional patch cables.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS 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.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Triggers Each channel pair of the A12 has its own Remote Turn On/Muting circuit (TRIGGER INPUTS 1/2-11/12). Individual channel pairs can be muted or un-muted independently 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.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS 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.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Speaker Connections Six removable flip-lock connectors allow for easy speaker wire terminations for up to twelve speakers. Use 28-16 AWG stranded copper speaker wire to connect from a zone's speaker location to the output terminal of an A12 amplifier. +L - - R + Figure 3-11: Speaker Flip-Lock Terminal Connection To make connections: 1.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS Chapter 4: Operations & Settings Setting Channel Levels The A12 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 decreases the level. Factory default is 50%.
A12 INSTALLATION MANUAL ELAN HOME SYSTEMS Turn-On Modes Use any of the following methods to mute/un-mute the A12: Default Mode • No TRIGGER INPUTS are connected. • AUDIO SENSE button is Off. – All channels are un-muted when power switch is On. Audio Sense Mode • AUDIO SENSE button is On. – Specific channel is muted if audio is not detected on that channel. – Specific channel is un-muted when audio is detected on that channel.
ELAN HOME A12 INSTALLATION MANUAL SYSTEMS Chapter 5: Troubleshooting Symptom Possible Cause Solution No Audio From One or More Channels 1. Loose/bad speaker cable connection 1. Check cable ends at binding posts 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. Speaker is defective 3. Swap with known good speaker. 4. RCA patch cable defective 4.
A12 INSTALLATION MANUAL ELAN HOME 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 3.
