Before you proceed, find the serial number which is located on the rear panel of the unit and note it here for

Placement of your HCA-800II

Keep your Parasound HCA-8OOII out of direct sunlight and away from windows which could ever be left
open to let in rain. It should be placed away from heat sources such as hot air ducts or radiators; do not place
the unit directly on a pile carpet that could interfere with air flow into its bottom vent openings. If you place
the HCA-8OOII on the floor near your speakers, elevate it up from the pile of the carpet. If you stack your
components, it is better to place the HCA-800II above or alongside your other components; when driven
hard, the unit itself may create a little heat and disturb components stacked on top of it. If it is inside a
cabinet, allow ample ventilation. Very sensitive low level sources might pick up some hum radiated from its
enormous power supply.

Making Connections

Before making any signal or speaker connections, make sure your power amplifier is turned off. When
making connections, make sure there is no strain or tension on input leads or speaker wires that could cause
them to pull loose later on.

lnput connections

In most stereo systems, you will use the gold-plated RCA jacks for the R and L channels. Make sure these
are consistent with the R and L outputs from your preamplifier.

Speaker connections

You may use either bare wire or banana plugs with the HCA-800II "5-way" terminals. If you use bare wire
without spade lugs or plugs, make sure you strip only enough wire to fit into the hole that runs across the
metal shaft of the terminal. Before inserting the wire, twist all its strands tightly to prevent strays that could
cause a short circuit between + and - terminals!
