Making Connections to Your Amplifier
Leave the AC cord disconnected before making any signal or speaker connections. When making
connections to the amplifier, make sure there is no strain or tension on the input leads, speaker wires,
or AC cord that could cause them to pull loose.
Home Theater Configurations and Input Connections for the HCA-1205A
Refer to Figure #1
Your HCA-1205A is primarily designed to deliver the same power and sonic characteristics to the
Left, Center, Right, and both Surround speakers of your home theater system. For additional low
frequency response, you should also install a powered subwoofer. Even though all the channels of
the HCA-1205A operate identically, we recommend the following configuration to make it easier to
identify each channel in case you ever need to troubleshoot your system.
〈
Connect the left front output of your processor to INPUT 1 of your HCA-1205A.
〈
Connect the right front output of your processor to INPUT 2 of your HCA-1205A.
〈
Connect the center output of your processor to INPUT 3 of your HCA-1205A.
〈
Connect the right surround output of your processor to INPUT 4 of your HCA-1205A.
〈
Connect the left surround output of your processor to INPUT 5 of your HCA-1205A.
〈
Connect the subwoofer output of your processor to the input of your powered subwoofer.
Home Theater Configurations and Input Connections for the HCA-1203A
Refer to Figure #2
If you are converting your existing two channel stereo system into a home theater system, you can
use the HCA-1203A to power the front Left, Center, and Right speakers. This allows you to use your
existing two channel stereo amplifier to drive your left and right Surround speakers. You can also
add a powered subwoofer for extended low frequency response. Use the following input
configuration so you have an easy way to remember the connections to each channel for level setting
and troubleshooting:
〈
Connect the left front output of your processor to INPUT 1 of your HCA-1203A.
〈
Connect the center output of your processor to INPUT 2 of your HCA-1203A.
〈
Connect the right front output of your processor to INPUT 3 of your HCA-1203A.
〈
Connect the right surround output of your processor to INPUT 1 of your two channel amplifier.
〈
Connect the left surround output of your processor to INPUT 2 of your two channel amplifier.
〈
Connect the subwoofer output of your processor to the input of your powered subwoofer.
If you are converting your existing two channel stereo system into to a home theater and you prefer
to keep using your existing two channel amplifier for your front left and right channels, you can use
your HCA-1203A for the front Center and Left and Right Surround channels. You can also add a
powered subwoofer for extended low frequency response. Here is the suggested input configuration
for this option:
〈
Connect the left front output of your processor to INPUT 1 of your two channel amplifier.
〈
Connect the right front output of your processor to INPUT 2 of your two channel amplifier.
〈
Connect the center output of your processor to INPUT 1 of your HCA-1203A.
〈
Connect the right surround output of your processor to INPUT 2 of your HCA-1203A.
〈
Connect the left surround output of your processor to INPUT 3 of your HCA-1203A.
〈
Connect the subwoofer output of your processor to the input of your powered subwoofer.
