About
Ooberpad proudly brings to you the dynamic Parasound Halo A 52+ Multichannel Amplifier. The Parasound A 52+ is based on Parasound's previous and hugely successful A 52 model and features relevant upgrades in power output, circuitry refinements, and of course, is equipped with the latest Halo styling. The new model enhances the available power from 125 to 180 watts per channel into 8 ohms and 255 watts into 4 ohms, with all channels driven. As with its predecessor, the Parasound Halo A 52+ is the work of audio legend John Curl, leveraging high-bias Class A/AB and direct-coupled circuit topology.
Warranty
1-year manufacturer's warranty
Key Features:
- Class A/AB circuitry designed by legendary John Curl

- Balanced XLR inputs with discrete circuits
- Full power is rated all the way down to 5Hz for unrestricted low-end bass
- Custom 1.5 kVA encapsulated toroid power transformer with independent secondary windings for each channel
- Hand-matched JFETs for input stage
- Hand-matched MOSFETs for driver stage
- Beta-matched 15 amp, 60 MHz bipolar output transistors (3 pairs per channel)
- 100,000 µF power supply filter capacitance
- DC Servo and relay protection circuits
- Auto turn on by audio signal or 12V trigger
- Heavy-duty 24k gold-plated, 5-way speaker terminals
- 3U chassis with updated cosmetics, rack mountable with HRA3 (sold separately)
Benefits of Parasound Halo A 52+ Multichannel Amplifier:
Power-packed With Upgraded Features
Centred around Parasound's previous and highly successful A 52 model, the upgraded Parasound Halo A 52+ features a larger custom-made toroidal power transformer to lend support to its higher power output. It has five RCA unbalanced and five balanced XLR inputs, a separate module for each channel, DC Servos and relays to safeguard the amp and speakers. Features comprise of automatic turn-on, a 3U chassis with rear carry handles which is rack-mountable with optional adaptors. The A 52+ has a black anodized extruded front panel with new sturdy aluminium end-caps that are milled and hand-polished. These embody a fresh and refined Halo appearance.
