About the Halo JC 1
The Parasound Halo JC 1 is a high-end monoblock power amplifier co-designed by legendary engineer John Curl. It features a complementary differential J-FET input stage, push-pull MOSFET drivers, and nine pairs of 15-amp bipolar output transistors for exceptional power and control. Direct-coupled from input to output with DC servo circuits, it eliminates capacitors in the signal path for superior clarity and bass response. Capable of 400W RMS into 8 ohms, 800W into 4 ohms, and 1200W short-term into 2 ohms, with 25W Class A on high bias. Weighing 64 lbs, it offers robust build quality at an accessible price point for its performance. The JC 1+ is its upgraded successor with higher power and refinements.
