Frequently Asked Questions - Halo JC 2 Parasound
How do I connect my speakers to the Halo JC 2?
The Halo JC 2 is a preamplifier, not an amplifier. It provides line-level outputs. Connect these to a power amplifier via unbalanced (RCA) or balanced (XLR) cables. Then connect speakers to the power amplifier.
What is the difference between balanced and unbalanced connections?
Balanced connections (XLR) provide better noise rejection over long cable runs. Unbalanced (RCA) are standard for shorter distances. The JC 2 supports both; use whichever matches your equipment.
Can I use the JC 2 with a home theater system?
Yes, but it is a stereo preamp. For home theater, you would typically use it for the front left and right channels, with a separate processor for surround sound.
How do I operate the volume control?
Use the front panel rotary knob or the remote control. The volume adjusts in 0.5 dB steps and is motorized for smooth operation.
What is the recommended power amplifier for the JC 2?
Any high-quality power amplifier with sufficient gain. Parasound Halo series amplifiers like the A21 or A23 are ideal matches.
How do I clean the unit?
Unplug the unit and wipe the exterior with a soft, dry cloth. Do not use any liquids or abrasive cleaners.
Why is there no sound output?
Check that the JC 2 is powered on, the correct input is selected, and the volume is turned up. Ensure your power amplifier is on and connected properly. Also verify mute is not engaged.
Can I connect a subwoofer directly to the JC 2?
The JC 2 does not have a dedicated subwoofer output. You can use a Y-splitter from the main outputs to connect to a powered subwoofer with speaker-level inputs, or use a separate crossover.
What is the purpose of the phase switch?
The phase switch inverts the absolute polarity of the signal. Use it if you notice bass cancellation or imaging issues, typically when comparing recordings or system setups.
How do I update the firmware?
The Halo JC 2 is an analog preamplifier and does not have firmware updates. All circuitry is analog and designed for long-term stability.
