SAFETY PRECAUTIONS

PLEASE READ BEFORE INSTALLING

WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should be
taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with wet
hands.

• The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the
presence of uninsulated “dangerous voltage
electric shock to you.

” within the product’s enclosure that may constitute a risk of

• The exclamation point within an equilateral triangle is intended to alert the user of the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the unit.

• Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.

• Unplug the amplifier from the AC outlet when plugging in or unplugging cables, when left unused for an
extended period of time, moving the amplifier, or when you suspect lightning in your area.

• Prevent damage to the power cord. Do not bend, pull, place objects on, alter, etc. Replace the power cord
if it becomes damaged. Always grasp the plug on the power cord when plugging in or unplugging the
amplifier from the AC outlet.

• Your system may produce sound levels capable of causing permanent hearing loss. Do not operate for
extended periods of time at high volume levels.

• Make sure the amplifier is placed on a level surface.

• The amplifier is equipped with raised feet to provide ventilation, reduce acoustic feedback, and provide

protection against scratching the surface the unit is resting on. We advise against removing or altering
feet.

• Do not stack anything on top of the amplifier (processor, source, etc.) Leave a minimum of 2” clearance
from the top of the amplifier to the next shelf (or component) to insure proper ventilation.

• The amplifier should be located away from other sources that may be sensitive to heat.

• Do not perform any internal modifications to the amplifier.

• Always connect the amplifier’s power cord to an unswitched AC outlet for normal operation.

• If young children are present, adult supervision should be provided until the children are capable of

following all rules for safe operation.

• Do not plug the amplifier’s power cord into an outlet with an unreasonable number of other devices. Be
careful if using extension cords and ensure the total power used by all devices does not exceed the
power rating (watts/amperes) of the extension cord. Excessive loads may cause the insulation on the
cord to heat and possibly melt.

• Mistaking CONTROL OUTPUT or CONTROL INPUT connectors for audio/video inputs or outputs may
damage your amplifier or other components.

• Damage can occur to your speakers if the power rating of each individual driver is exceeded by the
amplifier. Ensure that all the drivers in your system are capable of handling not only the average power
being delivered by the amplifiers, but also the peak power that is likely to be generated during strong
passages. If you are unsure of your speaker's power rating, contact the speaker manufacturer or the
dealer where you purchased them.

• The amplifier should be serviced by qualified personnel when:

A. The amplifier is not functioning properly.
B. Objects have entered the chassis.
C. The amplifier was exposed to rain or other type of moisture.
D. The amplifier was dropped, or the chassis is damaged.

PURPOSE AND FUNCTION

The AV2600 is an integration of a stereo audio distribution BUS with six compact and efficient 60 W power
amplifiers. Each pair of amplifiers have DIP switches that allow system configuration for use with either
mono/stereo and muting control via a Master or Local control input. Additionally, there is support for paralleling
multiple speaker output channels to allow greater output current capability. It is clear the AV2600 is designed to
allow flexibility and functionality in the design of Multi Zone power system applications. The term versatile is
almost inadequate to describe the multitude of operational modes the AV2600 is capable of providing.

Below are just a few of the tasks the AV2600 may be configured to perform:

• The most obvious example allows for three stereo audio input pairs to power three pairs of
amplified speaker outputs. This is the default factory configuration.

• Using the audio distribution BUS, DIP switches allow independent configuration for up to 3 pairs of
mono or stereo, with independent automatic audio sense muting per amplifier output pair.

• The availability of both Local and BUS audio outputs, allows for a number of units to be cascaded
for easy and efficient system expansion.

FEATURES

Toroidal Transformer - Efficient high current power delivery for improved dynamics.

Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for high transient power

delivery and extended low frequency control.

Limited Protection - Increased Safe Operating Area and thermal overload allows for continuous duty unattended

use.

Gold Plated Connectors - Improved connections for better sound and minimized signal loss and degradation.

1% Metal Film Resistors - Low noise precision resistors offer a cleaner more repeatable sound quality.

High Current Circuitry - More accurate and three dimensional reproduction of source material with sonic fidelity

usually found only in larger power amplifiers.
