Audio Input And Output Connections - Parasound HALO JC 3+ Owner's Manual

Connecting your JC 3+
Always disconnect the AC cords to your JC 3+ and power amplifier(s) before making or
changing any input, output or trigger wire connections. Inserting or removing an input or
output cable while the JC 3+ or power amplifiers are turned on can result in a blast of sound
that can damage your loudspeakers. Make sure there is no strain or tension on any cables
that could cause them to pull loose.
Audio Input Connections & Settings
Connect your turntable's signal cables to the Input jacks on the JC 3+. It is a good idea to
treat the turntable cable's RCA plugs with Deoxit (http://www.deoxit.com/) to remove any
oxidation on them. The turntable's ground wire attaches to the JC 3+ Ground terminal that is
located between the two channel inputs and outputs.
Note: In some cases eliminating hum might require connecting your turntable ground wire
directly to your line stage preamp instead of to the JC 3+. You can use any chassis screw on
your line stage. In rare instances hum might be lowest if your turntable ground wire is not
attached at all.
Important Note: Turntables and phono preamps are very sensitive to electromagnetic fields
that can cause audible hum. To minimize hum follow these guidelines:

Place your turntable as far as possible from power amplifiers or power line conditioners.

Run your turntable signal cables as far as possible from power amplifiers or power
line conditioners.

Do not run the turntable signal cables parallel with any AC cords.

Wherever turntable signal cords must cross AC wires they should cross at a 90

It might be necessary for you to experiment with the exact positioning of the turntable
signal cables to minimize hum.
