Frequently Asked Questions - Halo JC 3 Jr. Parasound
How do I connect the Halo JC 3 Jr. to my turntable and amplifier?
Connect your turntable's RCA cables to the Input jacks. Use the Output jacks to connect to your amplifier or receiver. If your turntable has a ground wire, connect it to the GND terminal. Ensure the amplifier is set to a line-level input (not phono).
What gain setting should I use for my cartridge?
The gain is selectable via the Gain switch on the rear panel. For most moving magnet (MM) cartridges, use 40 dB. For low-output moving coil (MC) cartridges, try 50 dB or 60 dB. Adjust based on listening level; avoid clipping.
How do I adjust the impedance and capacitance for my MC cartridge?
Impedance and capacitance are set via internal dip switches located under the bottom cover. Refer to the manual for specific settings. Common MC impedance values: 100 ohms, 47k ohms. Capacitance is typically 100 pF.
Why does my system hum when the preamp is connected?
Hum can be caused by a ground loop. Ensure your turntable's ground wire is attached to the GND terminal. Try reversing the AC plug orientation. Keep signal cables away from power cords. If using balanced connections, ensure proper shielding.
Can I use the subsonic filter?
Yes, the Subsonic Filter switch on the front panel activates a rumble filter to remove low-frequency noise (below 20 Hz). Use it if you experience woofer flutter or turntable rumble.
What is the mono switch for?
The Mono switch sums the left and right channels into mono. Use it for mono recordings or to reduce noise in stereo playback.
Does the JC 3 Jr. work with 78 rpm records?
The JC 3 Jr. does not include an EQ curve for 78 rpm records. It is optimized for the RIAA curve used by modern LPs. For 78s, an external equalizer is required.
What type of power cord does it use?
It uses a standard IEC C7 (figure-8) power cord. Ensure the voltage matches your region (100-120V or 220-240V, 50/60Hz).
How do I clean the unit?
Disconnect the power cord. Use a soft, dry cloth to wipe the chassis. Do not use any liquids, solvents, or abrasive cleaners. Avoid cleaning the internal components.
Is the JC 3 Jr. repairable if it stops working?
Yes, but only by authorized service centers. Do not attempt to open the unit. Contact Parasound or your dealer for repair services. There are no user-serviceable parts inside.
