            Benefits of Parasound Halo A 51 Multichannel Amplifier:

            High Bias Class A/AB operation
            High Bias Class A/AB operation

            The Halo A 51 is ideal for any higher-end multi-channel application and will drive the most demanding of loads within a system - so it is a good choice not just for the top-notch quality custom installation in-wall systems but obviously is equally sure-footed with large floor-standers as well. The root of this adaptability is primarily its 2.2 kVA encapsulated toroid power transformer with independent secondary windings for each channel, plus the A51's high bias class A/AB operation working in tandem with its directly coupled design (there are no capacitors or inductors in the signal path).

            The synergy of power and dynamism are quantifiable as the A 51 can output between 250 watts to 400 watts per channel - this is a real-world measurement as this is whilst all channels are being driven (20 Hz - 20 kHz - 60 amperes peak per channel). This high power and high current output performance deliver very flexible dynamic 'headroom', which is why the amplifier can be sublimely subtle when required, and unabatedly severe when raw power is needed.

            As anticipated, the build quality and components used in the A 51 are superlative. The seriousness of the amplifier can be seen externally with the casework - as the A 51's 4u chassis is robustly constructed to the most stringent standards and also has rear-mounted carry handles (rack mounting adapter included for custom installation applications) for moving its dynamic footprint to where it’s required.
