Amplifier
The
Parasound’s Halo JC 1 Monaural Amplifier is quite possibly the world’s finest
Series
component that is setting a new standard for elegance, sonic precision and value. W ith 25 watts of pure C lass
A power and 135 amps of peak current, this amplifier will provide a truly breathtaking audio experience, and in
systems where heat dissipation is a concern, a unique bias level adjustment allows for 10 watts of C lass A
instead of 25 watts. For the most demanding loads, the JC 1 offers 400 watts of power into 8W, 800 watts into
4W, and 1200 watts into 2W. John Curl’s discrete complementary design employs only the finest parts available
including Sanken output transistors, N ichicon Gold Tune capacitors, and Vampire copper wire and RC A
connectors. O ther features include balanced X LR and unbalanced RC A connectors, a 12v trigger, an audio
sensitivity trigger, a variable turn-on delay and a ground lift switch. Advanced circuitry, premier parts selection,
unequaled sound quality, and stunning design are bound to secure this amplifier a place in audio history.
