Parasound JC 1’s

Product Description

The JC 1 is a brawny brute weighing 64 lbs. It outputs 400W into 8 ohms, 800W into 4 ohms, 135 amps of peak current, and 25W of pure class-A power into 8 ohms. According to a blurb by John Curl that accompanies the amp, the design is “based on a complementary differential J-FET input stage followed by two stages of selected push-pull MOSFETs ultimately driving nine pairs of the most powerful complementary bipolar power transistors that are available today.”

Solid-state mono block power amplifier. Maximum output power (20Hz-20kHz): 400W into 8 ohms (26dBW), 800W into 4 ohms (26dBW) “continuous”; 1200Wpc into 2 ohms (23.6dBW) “short term.” Class-A power, 25W into 8 ohms (14dBW); bias set to Low: 10W into 8 ohms (10dBW). Frequency response: 2Hz-120kHz, +0/-3dB. THD: <0.15% at full power, <0.018% at typical levels. IM distortion: <0.03%. Input impedance: 100k ohms. Input sensitivity: unbalanced, 1V for 28.28V output into 8 ohms (100W); balanced, 1V per leg for 28.28V output at 8 ohms.
Dimensions: 17 3/4″ W by 7 5/8″ H by 20″ D. Weight: 64 lbs.
