It Holds Nothing Back in Power or Performance

The Parasound Halo A 31 was designed in response to increasing demand for a three-channel power amplifier that holds nothing back in power or performance. The A 31 is identical in performance and sound to the award- winning Halo A 51.

Lots of Application Versatility

You’ll find lots of uses for the three-channel A 31. It’s fantastic for powering the front three channels of a home theater. The surround or back channels can then be powered by a smaller two-channel Parasound power amplifier, such as the Halo A 23. This gives the greatest power to the front channels where it is needed the most.

You might also want to use the A 31 to power the center channel and two surround channels of your home theater. This allows the left and right front speakers to be powered by a dedicated two-channel power amp, such as the Halo A 21, or better yet, two JC 1 monoblock amps. This is ideal for the music lover who is unwilling to compromise stereo reproduction.

Here’s one more suggestion. Use the A 31 to power the front three channels in an AV receiver-based system. The remaining surround and back channels can be driven by the receiver. This assures you of the best sound for the front channels while enabling the receiver to produce more power for the surround and back channels.

However you employ the A 31, you will be delighted by its impeccable sonics, striking authority, and faithful reproduction of the smallest details.

“Impeccably Built and Beautiful”

“The Halo A 31 is able to drive any speaker you are going to throw at it and not complain, as well as being impeccably built and beautiful in appearance,” notes Chris Heinonen in his December 5, 2012 review for Secrets of Home Theater and High Fidelity. “In fact, it performed so well I let Parasound know I’ll be paying for it and keeping it as my reference amp going forward.”

Raw Power Plus Elegant Circuit Design

The three-channel Halo A 31 power amplifier combines raw power with elegant circuit design. Designed by legendary audio guru John Curl, the Halo brings uncompromising audiophile performance to home theater.

THX Ultra 2 certification ensures movie-house quality sonics, but the Halo surpasses this critical benchmark by delivering Parasound-quality sound derived from the ultra-high-end Parasound JC-1 400-watt mono amp. It has adjustable gain for up to +6 db over THX Reference level. Matched JFET inputs, MOSFET drivers, and high-current bipolar outputs contribute to its exceptional performance.

Class A/AB Operation and Impressive Firepower

The A 31 boasts balanced inputs with discrete circuits and XLR connectors. Beautifully implemented high-bias Class A / AB operation makes the most of an impressive 250-watt-per-channel power output at 8 ohms and 400-watts-per-channel at 4 ohms.

The 1.5 kVA encapsulated toroidal power transformer with independent secondary windings for each channel and 98,400 µF power supply filter capacitance delivers an impressive current capacity of 60 amps per channel. The direct-coupled design uses no capacitors or inductors in signal path. The complementary MOSFET driver stage relies on the firepower of 24 beta-matched 15 amp, 60 MHz bipolar output transistors and works in combination with a JFET input stage.

‘Instant’ Warm-up Feature

Like all the other amps in the Halo product series, the A51 has Parasound’s exclusive bias circuit, which permits the amplifier to sound perfect from the instant it’s turned on, rather than having to wait for bias to gradually build up as the amp warms up over time. Very high bias allows greater Class operating range than others. Even Halo’s implementation of its automatic turn-on feature is exceptional. Special relays bypass the AC “soft start” circuitry after it’s done its job for the purest AC and the purest sound.

And That’s Not All…

AC present, channel status, and high temperature indicators team up with DC Servo and relay protection circuits to keep this powerhouse running safely at peak performance for years of reliable service. Auto turn-on by 12-volt trigger or audio signal simplifies home theater and multi-room operation. Other features include heavy-duty 24k gold-plated 5-way speaker terminals, gold-plated RCA input jacks, and a rear-panel ground lift switch.

Parasound

As the nationally recognized leader in the field of high-end audio, home theater and home electronics, Overture is proud to offer Parasound’s line of high-performance music components including the new Halo JC 1+ that is the ultimate achievement of Parasound legendary designer John Curl. In the complicated landscape of audio, many companies put stratospheric price tags on great performance. Parasound’s mission couldn’t be more different. Simply put, they offer the most performance for the money by finding the sweetest spot between price and diminishing returns. Everything they do at Parasound is customer-centric because that’s how they define value. When they develop a new product they take the carpenter’s adage “measure twice, cut once” to the extreme. Each new model is tested, improved and re-tested under worst-case conditions. It comes to market only when it is a finished product that’s ready to stand the test of time. In fact, they don’t really know how long their amplifiers last because people write to thank them because the Parasound amp they purchased in the mid-’80s still works perfectly 30 years later. When you choose Parasound you’re getting uncompromised quality for every model. They all use the best parts and each must pass their strictest quality assurance. They wouldn’t have it any other way.
