About the Parasound Halo JC 5

Designed to deliver plenty of power

Parasound's 73-pound JC 5 delivers a whopping 400 watts per channel, and it's stable enough to drive just about any speakers you might care to hook up. In bridged mode, this amp really turns on the juice, putting out an amazing 1,200 watts into a single channel. All that power comes from a beefy toroidal transformer and a high-bias Class A/AB amplifier design that help your system reproduce music with stunning clarity and accuracy. The "JC" designation — and the signature on the front and back panels — lets you know it was designed by the company's audio design guru John Curl (more on him later).

Interior of Parasound Halo JC 5 amplifier

Parasound's Halo JC 5 amplifier delivers a mighty 400 watts per channel of clean power, thanks to design details like its massive custom power transformer.

Class A/AB operation for smoother sound

You don't see a Class A/AB amplifier every day, so let's break down the benefits.

Engineers and audiophiles generally agree that Class A designs offer the purest sound, but they tend to run hot and take up a lot of space. As a result, home audio amplifiers often use a compromise known as Class AB, which hands off part of the audio signal to a different set of output transistors at high power levels. AB can sacrifice a bit of signal purity, but it lets the amp run cooler and more efficiently.

So this Class A/AB amp operates in pure Class A mode up to a higher power level than most other amplifiers in its price category, before the second set of transistors kick in. The result is a sound that's smoother, less fatiguing, and more natural.

Convenient connections

On the back panel are balanced XLR and unbalanced RCA inputs for each channel, and each has its own individual gain control knob and loop output. There are also binding posts for connecting a pair of speakers. The amp can be rack mounted using the included ears.

The legacy of John Curl

The Halo JC 5 features circuitry designed by John Curl, a legend in audio engineering. He started his career in the 1970s, designing tape and video recorders at Ampex, and he had a hand in building the Grateful Dead's famous Wall of Sound. Curl has worked with Parasound since 1989, designing all of their high-power amplifiers and more. The power supply, transistors, capacitors and other parts in the JC 5 were chosen to offer uncompromising audiophile-grade performance.
