Power Control Connections
Your amplifier features a built-in remote turn-on system
that will automatically switch the amplifier on when anoth-
er device in the system is switched on.
Remote Turn-On Using Products Equipped
with a Low Voltage Trigger Jack
Press the front panel power switch on the amplifier so that it
is in the ON position. Then, using an accessory cable with a
3.5mm mono mini-plug on each end, connect the trigger-
output jack on the rear of the source device to the trigger
input jack on the back panel of the amplifier. When these
connections are made, the amplifier will automatically turn
on whenever the triggering device is turned on.
Remote Turn-On Using External AC to DC Power Con-
verter
If your source device does not have a dedicated trigger jack,
it is still possible to activate the unit for automatic turn on
when a Switched Outlet is available on the rear of the source
device. To control the amplifier in this fashion, you will
need a small AC to DC power converter, capable of deliver-
ing a 3.3 to 24 volt DC signal. The DC voltage should termi-
nate in a standard 3.5mm type mini plug. This type of con-
verter may be obtained as a Power Adapter from many elec-
tronics retailers. When installing, press the Main Power
Switch on the front panel of the amplifier in so that it is in
the ON position. Plug the AC adapter into a switched outlet
on the source device that will be activated when you wish to
have the amplifier turn on. This may be the switched outlet
at the rear of an AC receiver or other audio equipment. Con-
nect the 3.5mm mini-plug from the adapter to the trigger-
input jack on the back panel of the amplifier. The amplifier
will now turn on and off automatically, based on the status
of the controlling device.
AC Line Connector and Power Cords
Once all audio and system connections have been made,
connect the supplied power cords to the amplifier first, and
then connect it to an AC power source. Please make certain
that the amplifier is turned off and that the device connected
to the remote trigger input is off when connecting the power
cord and plugging it into an AC outlet. Your amplifier is
supplied with two internationally approved (IEC) power line
connectors that accept the supplied detachable, high-current
capacity power cords. NOTE: Each power cord on the
AT6000 series is supplied with a 20-amp plug that has a
different prong configuration than the typical 15-amp plug.
The AT6000 series amplifiers are so powerful they cannot
reach their peak output from a single 15-amp circuit. The
power cords are designed specifically for 20-amp use,
providing a more robust connection to the amplifier than a
15-amp cord can offer.
WARNING: Always turn off the amplifier and unplug the power
cord before making any electrical connections.

Plug the AT6005, 6006 and 6007 into a 20-amp circuit only.
(The 6002, 6003 and 6004 may use 15-amp outlets). You may
find that your wall socket is not the same configuration and will
need to be changed in order to accept the 20-amp plug of the
AT6005, 6 and 7. 20-amp receptacles are inexpensive and can
be found at any hardware or home supply store.
WARNING: DO NOT attempt this yourself, but hire a qualified
electrician to make necessary changes. Under no circumstances
should the round third prong on the plug be cut, bent or in any
other way defeated as this may result in severe shock.
NOTE: It is NOT RECOMMENDED that you connect other power
amplifiers, or products with a high current draw, to the same AC
power circuit as the amplifier. If this is unavoidable, the Ultra-Soft-
Start circuitry of your amp will prevent excessively high inrush
current.
Amplifier Operation
After all connections have been made you are ready for opera-
tion. First, turn on the source components and processor in your
system. It is always a good idea to turn on your amplifier LAST.
This avoids the possibility of any turn on pops or transients from
other equipment being amplified and sent to your speakers where
they may cause damage. Always start with a low volume level on
your controller or preamp to avoid damage to your speakers.
Manual Turn-On
Simply press the front panel power switch to the "up" position.
There will be a short pause from the time the power is turned on
until power is applied to the speakers. This is intentional, and
protects your speakers from damage while the amplifier stabi-
lizes. To turn the unit off, press the Power button downward.
The ON indicator light will go out and the STANDBY light
and logo will illuminate. Press the logo to turn off the back-
light. Press it again to turn it back on.
Automatic Turn-On
Make certain that the connection to the controlling device is
correct. Whenever the controlling device is turned on, the am-
plifier will automatically turn on after a short pause. This pause
is intentional, and it protects your speakers from damage while
the amplifier stabilizes. You may also hear a relay click as dur-
ing start up. This is also normal. To turn off your amplifier,
simply turn off the device feeding the amplifier it's audio sig-
nals. The amplifier will automatically go into a standby mode in
a few moments.
Peak Indicator Light
This indicator circuit continually monitors the output level of
your amplifier. This light will come on if the amplifier exceeds
its maximum output capability on any channel. While this will
not harm the amplifier, it does warn of potential harm to your
loudspeakers if the light stays illuminated continuously for more
than ten seconds. The volume setting from your preamp or
source device must be turned down if this occurs.
