Parasound Halo JC1 Power Amplifier

Operating in Class A means the amplifier's output transistors are always on, which eliminates the switching distortion common in other designs. This provides a smoother, more refined sound at lower listening levels, while the Class AB design seamlessly kicks in with more power when you need it for dynamic peaks.

Yes, the JC1 is exceptionally stable and capable of driving speakers down to 1 ohm. With a peak current capability of 180 amperes and a massive power supply, it maintains control over demanding loudspeakers that might cause lesser amplifiers to struggle or shut down.

While the JC1 offers both balanced (XLR) and unbalanced (RCA) inputs, balanced connections are recommended if your preamp supports them. Balanced cables provide better noise rejection, which is particularly beneficial for long cable runs in a high-end audio system.

The selectable 23 dB or 29 dB gain settings allow you to better match the amplifier with your preamp's output level and your speakers' sensitivity. This helps optimize the signal-to-noise ratio and ensures your volume control has a usable, comfortable range.

Yes, the JC1 is rack-mountable, but keep in mind that each unit weighs 83 pounds and generates significant heat. You must ensure your rack is structurally sound and provides ample ventilation space around the amplifier to prevent overheating.

By isolating the power supply for the input stage from the main output stage, the JC1 prevents high-current demands from the output transistors from modulating the sensitive input signal. This results in greater clarity, lower noise, and a more stable soundstage.
