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
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.
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 the turntable signal cord must cross AC wires they should cross at a 90o right angle.
•It might be necessary for you to experiment with the exact positioning of the turntable signal cables to minimize hum.
