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
The A6 has many rear panel connections so it is important to label them all correctly. Label all input/output cable
and speaker wires with their destination or source and 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 A6's high quality, gold plated 5-way
binding post will accomodate 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.

Signal Routing
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 Mode Switch, such as the one on the A6, eliminates the
need for additional patch cables and adds to the flexibility of signal routing when all Outputs share the same Input.
Line Ouputs
A stereo or monaural audio signal connected to the A6’s main CHANNEL INPUT can be routed to any of the A6’s six
channels via the 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.
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 A6 Line Outputs are buffered, a maximum of four
amplifiers may be 'daisy-chained' to each Line Outputs.

Speaker Binding Post
The A6 is equipped with gold plated, 5-way speaker binding post. This allows for 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 Multi-Zone 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 A6 features independent Level Adjustment Potentiometers for each of its six 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 potentiometers 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.
