10OPERATING YOUR JC 2

Before turning the JC 2 on, recheck all your connections and turn down the volume control to avoid any unpleasant “blasts” that could damage your speakers.

Turn On Delay

The first time you turn on your JC 2 after connecting its AC power it will automatically mute for 45 seconds with its Mute indicator flashing red. This time allows the JC 2 to warm up and stabilize its circuits so you don’t hear any turn-on transients. After the first turn-on, its turn on delay will be only 4-5 seconds.

Note: Your JC 2 will also mute for 45 seconds the first time you turn it on after its AC power was interrupted or disconnected.

FRONT PANEL CONTROLS

On-Off Button

Push once to turn on. Push again to turn off. The Mute LED will flash for 4-5 seconds whiles its circuits stabilize. After the circuits stabilize the muting will disengage.

Input Select Button

The INPUT button selects the 6 inputs and a blue LED indicates which input is selected. You will select the next input each time you press it. Input 1 comes after input 6.

Volume Control

Your JC 2 employs a precision close-tracking four gang potentiometer to adjust master volume level. Adjust your power amplifier gain controls (if it has them) so that your JC 2 master volume knob’s indicator is between 11 o’clock and 1 o’clock for your most typical listening level. This is its “sweet spot” where the control’s left/right channel tracking is closest and its distortion is lowest.

Note: The JC 2 has a maximum gain of 14 dB, which is suitable for most power amplifiers, and for all Parasound power amplifier models, including the JC 1.

Left and Right Level Controls

Adjusting left and right channel balance is helpful to compensate for speaker placement, room acoustics or if your power amplifier’s gain isn’t identical for both channels.

The JC 2 does not have a conventional balance control knob because a single part would compromise crosstalk and impair the JC 2’s precise sound-stage reproduction. Further, in its center position a balance control potentiometer’s wipers remain in the audio circuit. There are no balance control potentiometers which meet Parasound’s quality standards for the JC 2.
