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

1. AC fuse holder - The AC Line fuse. The fuse is an 8 Amp / 250 Volt Slow Blow fuse. Replace with same type
and value fuse only.
2. Channel control input/output - Each pair of amplifier channels has its own 1/8” mini control input / output
(pass through) ‘Local’ control jack to provide remote switching of the amplifier audio mute on/off feature. The
control input circuit is designed to work as Tip Pos. (+) and Ring Neg. (-). A minimum of 5VDC @ 1 mA is
recommended, and is compatible with up to 24V AC or DC.
3. Dip switches - Each pair of amplifier channels has its own DIP switches that are used to configure the audio
signal (‘Local’ or ‘BUS’, mono or stereo and muting control).
4. Channel inputs and outputs - Each pair of amplifier channels has its own ‘Local’ set of audio input / output
(pass through) RCA connections. Typically used for connecting signal patch cables (interconnects) from the
preamplifier to the amplifier.
5. Channel level control - Each pair of amplifier channels has its own DUAL input level control. The level of both
amplifier channels is set via this control.
6. Master control input/output - The AV2600 is designed to provide control for single switching of the amplifier
audio mute on/off feature on any pair of amplifier channels (1-2, 3-4 or 5-6) with it’s DIP switch ‘MASTER’ set to
ON. The control input circuit is designed to work as Tip Pos. (+) and Ring Neg. (-). A control source capable of
sourcing a minimum of 5 VDC @ 1 mA is recommended, and is compatible with up to 24V AC or DC.
(The Master control output DOES NOT source any voltage directly, it will only PASS through the input
voltage at it’s input).
7. Bus inputs and outputs - In a similar fashion to the Master control input, the AV2600 has a provision for a
stereo audio distribution ‘BUS’. This BUS allows stereo inputs to source audio to amplifier channels (1-2, 3-4 or 5-
6) when the DIP switch ‘BUS’ is set to ON. Simultaneously, buffered ‘BUS’ stereo audio outputs are provided to
allow audio distribution and system expansion.
8. AC Input receptacle - Connect the supplied AC power cord to the amplifier.
9. Speaker outputs - ‘Five way’ binding post terminals allow support for various speaker wire termination. To
prevent damage to the speakers or amplifier, always verify there is no possibility of shorting multiple speaker
terminals together.

DIP SWITCH SETTING
Each pair of amplifiers have their own set of four DIP switches. The function of each switch is described below:
AMP ON: (ON is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘AMP’ set to ‘ON’, have the remote Master and Channel switching of
the amplifier audio mute on/off feature disabled. When remote amplifier audio muting is desired by
either the Master or ‘Local’ Channel control input, the ‘AMP’ switch must be set to the ‘Off’ position.
SENSE OFF: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘SENSE’ set to ‘ON’, have the remote Master and Channel switching of
the amplifier audio mute on/off feature disabled. Amplifier pairs set to use ‘SENSE’ will mute
automatically after a delay of three minutes once no audio signal has been detected. The sense circuit
monitors the amplifiers selected audio, i.e.. ‘Local’ or ‘BUS’ mono or stereo. When remote amplifier audio muting
is desired by either the Master or ‘Local’ Channel control input, the ‘SENSE’ switch must be set to the ‘Off’
position. When the AMP ON feature is desired or automatic muting of the amplifier pairs is not desired, or if the
audio signal is erratic, the ‘SENSE’ switch must be set to the “Off’ position.
L + R: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘L + R’ (mono) set to ‘ON’, have the sum of the selected audio inputs,
i.e.. ‘Local’ or ‘BUS’, processed into a composite mono signal source for both amplifier channels.
When mono is not desired, or independent channel amplification of the amplifier pairs is necessary,
the ‘L + R’ switch must be set to the ‘Off’ position
BUS: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs (channels 1-2, 3-4 and 5-6), with DIP switch ‘BUS’ set to ‘ON’, have their inputs
sourced from the audio signals present at the BUS inputs. When the BUS feature is not desired and
the amplifier pair is to be sourced at the ‘Local’ audio inputs, the ‘BUS’ switch must be set to the ‘Off’.

CHANNEL CONTROL & MUTING
Each pair of amplifier channels has its own 1/8” mini control input / output (pass through) jack to provide remote
switching of the amplifier audio mute on/off feature. The control input circuit is designed to work as Tip Pos. (+)
and Ring Neg. (-). A minimum of 5VDC @ 1 mA is recommended, and is compatible with up to 24V AC or DC. A
preamplifier’s control output, such as is provided with B&K series preamplifiers, can be utilized to provide a
control signal to the AV2600. When ‘Local’ channel control muting is desired, the proper DIP switch configuration
must be set.
MASTER CONTROL & MUTING
The AV2600 is designed to provide for single switching of the amplifier audio mute on/off feature on any pair of
amplifier channels (1-2, 3-4 or 5-6) with it’s DIP switch ‘MASTER’ set to ON. The Master control output is a pass
through of the Master control input. The control input circuit is designed to work as Tip Pos. (+) and Ring Neg. (-).
A control source capable of sourcing a minimum of 5 VDC @ 1 mA is recommended, and is compatible with up to
24V AC or DC. (The Master control output DOES NOT source any voltage directly, it will only PASS
through the input voltage at it’s input).
Note: When an 1/8" mini plug is inserted into the ‘Local’ amplifier pairs CTRL IN jack, the Master Control signal is
automatically disabled for that amplifier pair.
If more than one AV2600 or other units are to be controlled, the control signal can be expanded to include each
successive unit by simply running a 1/8" mini cable from the CTRL OUT connector of the first amplifier to the
CTRL IN connector of the next unit (commonly referred to as ‘daisy chaining’).
*Note: A control voltage is for muting control only. Each amplifier must be connected to its own source of AC
power in order for it to operate.
LEVEL CONTROL
Higher
(Louder)
Figure 2
Each pair of amplifier channels have their own ‘Local’ level control. It may be used to equally attenuate the level
for both amplifiers pairs. The level controls may be reconfigured so that they are bypassed (recommended for
high current output paralleling applications) by moving the jumpers inside the unit. See AV2600's internal
volume selection.
Default from the factory, the level controls are set to full clockwise (no attenuation). Note, there is a single level
control for each pair of amplifiers (1-2, 3-4 and 5-6) therefore, care should be taken in the assignment of the audio
signal source when used in applications when there is no relationship between the two amplifier pairs (i.e..
separate source material, one from a DVD player the other from a VCR.) Another example might be when using 4
ohm and 8 ohm speakers together, the 4 ohm (CH 1) speaker may sound louder then the 8 ohm (CH 2) speaker
when set to the same level.

INPUT CONNECTIONS
Each pair of amplifier channels have their own ‘Local’ input and output RCA connectors. The inputs are designed
to accept line level audio from a preamplifiers unbalanced output connectors. Output expansion is accommodated
with the supplied output connectors. These outputs are effectively a direct pass through from the inputs.

LEVEL CONTROL DEFEAT
The following procedures should only be performed by a qualified technician. Each pair of amplifier channels have
their own ‘Local’ level control that may be bypassed to allow paralleling output channels. The jumper modules are
located inside the unit, on the circuit board, just behind the level controls.
Figure 6 shows how jumpers are used to configure the AV2600 amplifier (level controls enabled). Rearranging
these jumpers allows configuring the amplifier for use without a level control (required for proper operation using
paralleled output channels).

SYSTEM INSTALLATION
There will most likely be a number of cables involved in the installation of your home entertainment system.
Preplanning is essential in order to maximize system efficiency. We recommend the following as a means of
helping you reach that goal.
Make a diagram of your proposed system by laying out the relative location of each component in the
system. Then lay out the proposed cable runs between them. Number each cable and record its length on
the diagram for future use.
Cable runs are critical in that they must be kept away from the sources of power radiation (amplifiers,
power cords, heaters, appliances, etc.). For safety reasons, they should also be kept out of traffic areas.
The process of optimizing the system will include the type of cable, the length of the run, and the
obstructions it must deal with along its run. Your dealer can advise you on the products available and
their relative merits. If building custom length audio cable is not your strength, you dealer should be able
to help you with that as well.
When possible, use a separate AC power line for the amplifier, one that is not shared by any other
household component. THIS IS VERY IMPORTANT!!!
Tip:
Take a piece of string (longer than the longest cable run) and mark it at each foot of length. Then do a mock
cable run using the string, dressing it neatly along the way. Count the divisions to the next full foot, and add one
foot to all for some movement of the components. This will provide you with ideal cable length.
MAKING THE CONNECTION
Before doing anything, insure that the power switch on the amplifier’s front panel is in the ‘off’ position.
Again, it is recommended that you locate a separate AC power outlet for the amplifier, one that is not shared
by any other audio component in the system or any other household component. This will eliminate the
possibility of the amplifier ‘modulating’ the power being supplied to the component and compromising the
signal originating from that component.
Locate the AC power cord provided with the amplifier and plug it into the power input receptacle in the rear
panel. Do not connect it to the AC power source yet!
Connect the audio cable from your preamplifier’s output to the corresponding input connector on the amplifier.
Connect the wire from your speakers to the appropriate outputs on the amplifier. It is absolutely essential that
you observe correct polarity in all theses connections.
Example: If you connect your left output of your preamplifier to channel 4 input on the amplifier, remember to
connect your left speaker wires to channel 4’s outputs. Always observe polarity when connecting speakers,
connect amplifiers (+) to the speakers (+) and amplifiers (-) to speakers (-).
Double-check all connections.
Connect a playback unit (CD, DVD, VLD, Tuner, etc.) to the preamplifier. Turn on the preamplifier, turn the
volume on the preamplifier to a minimum level, and then turn on the amplifier (in that order). Set the source
on the preamplifier to the playback unit you’ve just connected. Turn the volume up slowly and listen for music
from all channels. If this is not the case, and you don’t hear any sound, double-check your installation.
Should you encounter any problem that cannot be traced to the source or the material being played, consult
the “TROUBLESHOOTING” section on page 10.
Note: When turning equipment ‘off’, the amplifier should always be turned off first, then the preamplifier. Before
turning anything on, insure the preamplifier is at a low volume level.

CARE AND CLEANING
Under normal use, the amplifier will not require any special care. Clean the exterior of the unit by wiping it with a
damp cloth to remove any dirt or dust that accumulates. Do not let any liquid enter the amplifier through its vents
or top cover. It is recommended that the connectors on the rear panel be cleaned annually using isopropyl
alcohol.
