Parasound Halo JC1 Single Channel Amplifier

Parasound Halo Premier Monaural Amplifier

Parasound’s Halo JC 1 Monaural Amplifier is quite possibly the world’s finest power amplifier. Collaborating with legendary audio designer John Curl and the team at CTC Builders, Parasound has created a no-expense-spared component that is setting a new standard for elegance, sonic precision and value.

With 25 watts of pure Class A power and 135 amps of peak current, this amplifier will provide a truly breath taking audio experience, and in systems where heat dissipation is a concern, a unique bias level adjustment allows for 10 watts of Class 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, Nichicon Gold Tune capacitors, and Vampire copper wire and RCA connectors. Other features include balanced XLR and unbalanced RCA 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.
