Parasound Halo JC-3+
One amazing Phono Pre-amp

  •   Designed by John Curl - creator of the legendary Vendetta Research phono preamp
  •   Inputs and outputs use Vampire brand 24k gold-plated RCA jacks
  •   Balanced outputs use Neutrik brand premium XLR jacks
  •   MM 47k ohm, MC 47k ohm or MC variable 50-550 Ohms
  •   RIAA accurate within 0.2 dB
  •   Exclusively Vishay-Dale resistors in the audio path
  •   Triple shielding; low-carbon mild steel partitions isolate the power supplies & AC wires
  •   Dual mono design; each audio channel is separately enclosed in its own extruded aluminum enclosure
  •   Separate high speed-soft recovery rectifiers, filter caps and voltage regulators for each channel
  •   Superior R-core type power transformer
  •   Mono switch can improve sound of mono and older LPs
  •   Built-in AC line conditioner to prevent AC noise from polluting the circuits
  •   AC polarity reverse switch can reduce hum in many systems
  •   Non-magnetic aluminum rear panel for purest sound
  •   Turn On Options switch: manual or auto with 12v trigger input
  •   Premium detachable heavy gauge IEC AC cord
  •   2u Chassis, rack mountable with HRA2 (sold separately)
  •  Parasound 5 year parts, 5 years labor warranty 
       (For USA and Canada purchases only)

    How the JC 3+ improves on the original JC 3:

  •   Variable MC load adjust independent for each channel from 50-550 ohms with dual gang potentiometers specially made for Parasound by Vishay.
  •   Curl-Thompson tweaked circuits to further reduce the JC 3 silent background noise.
  •   24k gold plated copper traces on phono module boards for utmost conductivity and most transparency/detail in the music.
  •   47% larger low ESD power supply filter caps greater reserve for head-snapping dynamics.
  •   82% larger R-core power transformer greater reserve for more low end impact.
  •   Ability to turn off illumination of the front panel P logo.
  •   Now Available in Silver or Black.
