Parasound HALO A31 Power Amp

The A31 is a three-channel amplifier, making it an ideal choice for powering the front stage of a home theater system—specifically your left, center, and right speakers. It provides the high-current muscle needed to drive demanding speakers that might otherwise sound thin or strained with a standard receiver.

Yes, as long as your receiver or processor has pre-amplifier outputs (RCA or XLR). You simply connect those outputs to the A31, and the amplifier will take over the heavy lifting of powering your speakers, leaving your receiver to handle signal processing.

Absolutely. The A31 is designed to deliver 400 watts per channel into 4-ohm loads, which is significantly more than its 250-watt rating at 8 ohms. This capability ensures it maintains control and clarity even with speakers that dip to lower impedances.

Yes, the A31 is rack-mountable. However, given that it weighs 65 pounds and generates heat during operation, ensure your rack has adequate ventilation and sturdy shelving to support its weight and size.

The Class A/AB design offers the best of both worlds: it provides the refined, low-distortion sound quality of Class A at lower volumes, while switching to Class AB operation to provide the raw power needed for dynamic peaks in movies and music.

Yes, it features both balanced (XLR) and unbalanced (RCA) inputs. Using balanced XLR cables is recommended if your processor supports them, as they provide superior noise rejection, especially over longer cable runs.
