System Installation
After unpacking the unit, and placing it
on a solid surface capable of supporting
its weight, you will need to make the
connections to your audio and video
equipment. These steps need to be done
only when the receiver is first installed,
or when a change is made to the input
source equipment.
Audio Input and Output Connections
We recommend that you use high-quality
cables when making connections to
source equipment and recorders to
preserve the quality of the signals.
When making connections to audio
source equipment or speakers it is always
a good practice to unplug the unit from
the AC wall plug. This prevents any
possibility of accidentally sending audio
or transient signals to the speakers that
may damage them.
1. For playback-only audio sources, such
as a CD player, CD changer, external
phono preamp or external digital to
analog converter, connect the output
jacks of the player to the appropriately
labeled inputs on the rear panel
NOTE: When the source device has both
fixed and variable audio outputs it is best
to use the fixed output unless you find
that the input to the receiver is so low
that the sound is noisy, or high that the
signal is distorted.
