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.

Chapter 3: Connections

Bussing

The term BUS is dened 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 exibility of signal routing.

Bus Input & Bus Loop Ouput

A stereo or monaural audio signal connected to the A12’s main BUS INPUT can be routed to any of the A12’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 amplier channels. Examples of both these applications are shown on the following pages.

The BUS LOOP OUTPUT is an easy way to add on additional rooms of music by connecting them to a second (or 3rd, or 4th) A12.

Bus DIP Switch Settings

There are independent BUS DIP switches for each channel on the A12. The DIP switches labeled BUS L (Left) and BUS R (Right) determine whether the signal connected 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) position will receive the audio signal from the BUS INPUT.

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. For example, if A12 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.

ELAN Multi-Room System w/ Direct Input Bussed Zones

The example below shows the use of the Left (odd numbered) inputs. The Right (even-numbered) inputs can also be used. Make sure to set the DIP switches correctly, as shown below, depending on whether Right or Left inputs are being utilized.

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. The 12 Volt DC SYSTEM TRIGGER OUT can be used to turn on other equipment, additional A12s or other amplifiers, or to perform automated functions desired by the user. Use 3.5mm mono interconnect cables to make Trigger connections.

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 OUTPUTs from an ELAN Multi-Room Controller, multiple A/V receivers triggering

separate A12 inputs, or outboard sensors located in certain areas to trigger specific inputs of the A12.

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.

TRIGGER INPUTS

Figure 3-9: System Trigger In

SYSTEM TRIGGER OUT

Whenever the A12 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-muting 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.

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. Cut the ends of the wire to length, allowing some free play (about 6 inches of slack) to allow for movement when physically connecting the wire.

2. Using wire strippers, remove 1/2 inch of insulation, then twist the wire to ensure that no stray strands are evident.

3. Define positive (+) and negative (-) at the amplifier end and the speaker end of the wire run and use the same conductor on each end.

4. Lift up each flip-lock connector until it is locked in the up position. Place the bare lead from each speaker wire into the holes of the flip-lock terminal of the A12, maintaining the polarity of each lead (+ to +, - to -).

+-+ -

Important Notes:

• Use 28-16 AWG Stranded Copper Speaker Wire

• Amplifier is Rated at 8 Ohms. Do Not Configure Impedance Below 8 Ohms.

• The amplifier is NOT bridgeable. Do NOT attempt to bridge or combine channels.

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%.

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.

LEVEL LEVEL

Factory Default 50%

Figure 4-1: Level Adjustment Potentiometers

Audio Sense

When Audio Sense is enabled (AUDIO SENSE button depressed), 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 active, the SYSTEM TRIGGER OUT will also become active. If Audio Sense is enabled, it will mute a channel once an audio signal is absent for a period of two minutes.
