...JC 2 BP Bypass Function Owner’s Guide Addendum.....

These instructions are for the model JC 2 BP and for a JC 2 that has been updated

to include JC 2 BP Bypass function. Here is how you can identify a JC 2 BP:

The front panel has JC 2 BP printed on it.

The front panel includes an additional indicator labeled Bypass which

is located between the Input 6 indicator and the Audio Mute indicator.

Its remote control handset shape and key arrangement are different.

Please read these instructions and cautions very carefully

: Even if you have extensive experience with setting up audio gear you should not..

.attempt..to set up the JC 2 BP’s Bypass function without following our instructions.......

What is the JC 2 BP Bypass?

The JC 2 BP bypass enables you to blend the JC 2 BP into a surround sound system by

inserting it into the Left and Right channel signal path “downstream” between your surround

processor or receiver and the power amplifier for your Left and Right speakers.

Note: The Bypass function works with either the JC 2 BP’s unbalanced RCA input jacks or its

balanced XLR input jacks.

How does the JC 2 BP Bypass work?

The JC 2 BP Bypass locks out the master volume control and the left and right channel gain

controls so its output level is fixed at unity gain. When the JC 2 BP output is fixed at unity gain

the signal level at its output jacks is the same as the signal level at its input jacks. The JC 2 BP

will be transparent to the left and right channel analog line level outputs from your surround

processor or receiver.

This will allow you to share amplifier(s) and speakers with both the JC 2 BP and your surround

sound system. Your analog sources will continue to be routed through the JC 2 BP and the left

and right channel signals from your surround processor or receiver will be unaffected by the JC

2 BP as they pass through it.

The Bypass function requires the JC 2 BP to be powered on, since its bypass circuit is active.

The Bypass function in the JC 2 BP has been accomplished without modifying the JC 2 left and

right channel audio boards in any way. The JC 2 BP measures and sounds identical to the JC 2

in every respect.

The Bypass Signal Path - Unbalanced Inputs (illustrated below) The surround receiver’s L & R Preamp Out jacks connect to the JC 2 BP Input 2 Unbalanced Input jacks. The JC 2 BP Main Output jacks connect to the Input jacks of the power amplifier driving the L & R speakers. The Bypass Signal Path - Balanced Inputs (not illustrated) If you have a surround processor with L & R balanced XLR analog output jacks you can connect them to the JC 2 BP Input 1 or Input 2 XLR jacks.

How to Assign an Input for the Bypass function Any of the six inputs can be turned into a Bypass input. This includes the balanced XLR jacks for inputs 1 and 2. To assign an input for the Bypass mode you must use the remote control supplied with the JC 2 BP to setup the Bypass function. The remote control supplied with the original JC 2 (non-BP version) cannot be used to assign a Bypass input. CAUTION: .

If you turn the JC 2 BP volume control knob manually while Bypass is selected you will not hear a volume change. But you did make a new volume setting and it will be instantly audible when you select a non-Bypass input. The resulting blast of sound could be loud enough to damage your speakers. How to Cancel or “Un-assign” Bypass Once you have assigned an input for Bypass mode it is possible to revert that input back to normal operation.
