Meet the A52+

The Parasound Halo A52+ Five Channel Power Amplifier is a reference-grade multichannel amplifier engineered to bring high-current control, low-noise resolution, and true all-channels-driven power to premium home theater and music systems. Designed by John Curl and built around a high-bias Class A/AB architecture, it combines effortless dynamic headroom with refined, tightly controlled playback—ideal for demanding speakers and modern processors/AVRs with pre-outs.

System note: Pair with a high-quality surround processor or AVR with pre-outs to unlock a substantial improvement in control, clarity, and transient authority across all channels.

Highlights & Benefits

• Real all-channels-driven power — rated 180 watts RMS × 5 into 8 Ω and 255 watts RMS × 5 into 4 Ω for consistent output under full surround loads.
• High-current grip and bass control — 45 amperes peak per channel and a damping factor > 1100 help maintain tight low-frequency control and cleaner transients.
• Low distortion, wide bandwidth — full-power performance down to 5Hz supports unrestricted low-end weight, with wide frequency response for stable imaging and detail.
• Balanced and unbalanced integration — five XLR inputs plus five RCA inputs for flexible pairing with processors and AVRs.
• Install-friendly power management — 12V trigger and audio-sense auto-on simplify daily operation in racks and custom installations.
• Premium multichannel foundation — the Parasound Halo A52+ Five Channel Power Amplifier is engineered for systems where clean headroom and channel-to-channel consistency matter most.

Technology & Design

High-bias Class A/AB topology — designed to deliver the finesse of Class A behavior at lower levels with the efficiency and power reserves required for cinematic dynamics.

Fully discrete, direct-coupled signal path — engineered to preserve detail and reduce coloration, with protection and servo strategies designed to maintain stability under real speaker loads.

Serious power supply architecture — a large encapsulated toroidal transformer and substantial reserve capacitance provide clean current delivery for five channels simultaneously.

Connectivity for advanced systems — balanced XLR and RCA inputs allow optimal gain staging and noise performance with premium processors and long cable runs.

For high-performance surround or multi-zone audio where every channel must remain composed, the Parasound Halo A52+ Five Channel Power Amplifier delivers controlled power with premium refinement.
