Mono and Stereo Power Amplifiers : Parasound Halo JC1 THX Ultra2 400w Mono Block Amplifier

Parasound Halo JC1 THX Ultra2 400w Mono Block Amplifier

The JC 1 Monaural Amplifier might possibly be the world's finest power amplifier. Parasound, John Curl and CTC Builders collaborated in the design of this amplifier to create a new standard for elegance, sonic precision and value. The JC 1 provides 400 watts into 8 ohms with 135 amps of peak current. Its 25 watts of pure Class A power is user-switchable to 10 watts of Class A power when heat dissipation is a concern. Other features include balanced XLR or unbalanced RCA connectors, a 12v trigger, an audio sensitivity trigger, adjustable turn-on delay, and a ground lift switch. Advanced circuitry, premier parts selection, unequaled sound quality, and stunning design are bound to make this amplifier a legend in its own time.
