Parasound Halo Series JC 1+ Mono Power Amplifier | 850W x 1 Channel | Silver

The Parasound Halo JC 1+ in silver is a monaural reference power amplifier designed for audiophile systems where separate channel amplification is essential. Sharing the same circuit design as its black counterpart, it outputs 450 watts into 8 ohms, 800 watts into 4 ohms, and 1,300 watts into 2 ohms from a single channel. The chassis measures 17.6 by 7.1 by 20 inches and weighs 83 lbs net, making it a substantial but manageable monoblock for high-end installations.

Peak current delivery is 180 amps. Distortion is rated at 0.05 percent THD, and frequency response extends from 2 Hz to 120 kHz within 3 dB. Signal-to-noise ratio exceeds 122 dB IHF A-weighted with bias set low and 120 dB with bias set high. A rear-panel switch selects between 29 dB and 23 dB of gain to accommodate different preamplifier output levels. Both balanced XLR and unbalanced RCA inputs are provided, and a 9-12 Vdc trigger input supports automated system control.
