Amplifier Connections
IMPORTANT NOTE: BEFORE ATTEMPTING TO MAKE ANY
CONNECTION TO YOUR POWER AMPLIFIER, MAKE SURE
THE AMPLIFIER IS TURNED OFF AND/OR DISCONNECTED
FROM AC POWER. FAILURE TO DO SO CAN RESULT IN SEVERE
DAMAGE TO YOUR AMPLIFIER AND/OR LOUDSPEAKERS.
Before attempting to make any connection to your power
amplifier, make sure the amplifier is turned off and/or
disconnected from AC power. Failure to do so can result in
severe damage to your amplifier and/or loudspeakers.
Main Zone
Use the audio jacks labeled AUDIO VIDEO OUTPUTS to connect
the A/V PROCESSOR to an external power amplifier such as
those from ATI. The A/V PROCESSOR can output up to 7.1
channels of sound (seven main channels and one subwoofer),
even when you are listening to 2-channel stereo material.
The output jacks supplied by the A/V PROCESSOR are: Front
Left and Right, Surround Left and Right, Surround Back Left
and Right, and Subwoofer (SUB) and Center (CEN).
Be sure to verify that the correct outputs are connected to the
appropriate input jacks on your amplifier—for example, Front
Left to Front Left, Surround Back Right to Surround Back
Right, etc. If the inputs on your amplifier are not labeled, it
probably does not matter which of the A/V PROCESSOR’s
output channels is connected to a particular amp channel.
However, you must be sure that the appropriate speaker is
connected to that amp channel.
When a powered subwoofer is used, connect the Subwoofer
output jack to the Line Input jack on your subwoofer (use
either the Left or Right input if your subwoofer has both) and
follow any specific connection and/or configuration
instructions supplied with the subwoofer. If your subwoofer
is a passive speaker (with no built-in amplifier), connect the
subwoofer output jack on the A/V PROCESSOR to the input of
the amplifier used to power the subwoofer, and then connect
the subwoofer speaker itself to the amplifier.
The ATP8700 offers both balanced (XLR) and unbalanced
(RCA) outputs. If your amplifier has balanced inputs, we
recommend you use balanced audio cables between the
ATP8700 and your amplifier. Using balanced cables could result
in a slight reduction in noise, and because XLR connectors
lock into place, they cannot come loose as RCA connectors can.
On the ATP8700, both balanced and unbalanced jacks are
active all of the time, so you can mix them up–for example,
using balanced connections for a high-end stereo amplifier
connected to your front left and right speakers, and
unbalanced connections for all of the other channels.
