Parasound JC3+ Phono Preamplifier
Reference-grade phono amplification designed to bring out every nuance in your vinyl collection with clarity, warmth, and dynamic precision.
The Parasound JC3+ Phono Preamplifier, engineered by the legendary John Curl, delivers exceptional analog performance for both moving magnet (MM) and moving coil (MC) cartridges. Its dual-mono architecture ensures absolute channel separation, while precision RIAA equalization within 0.2 dB provides a perfectly balanced, natural presentation of your records.
Each channel of the Parasound JC3+ Phono Preamplifier operates with its own power supply, transformer, and regulation circuit for vanishingly low noise. MM input loading is fixed at 47kΩ, while MC input loading can be adjusted from 50Ω to 550Ω independently per channel. With gain set at 48 dB for MM and 64 dB for MC, the JC3+ offers ideal flexibility for virtually any cartridge pairing.
Designed for quiet operation and detailed musical reproduction, the Parasound JC3+ features balanced XLR and unbalanced RCA outputs, a selectable mono switch for vintage recordings, and a 12V trigger input for seamless system integration.
