Parasound Halo A 21 Introduction
At first look the Parasound Halo A 21 and A 51 are appealing and robust amplifiers accented by brushed metal finish and a "Halo" aqua blue light around the power button. But an amplifier is not just about cosmetics especially when considering that most Audio Enthusiasts seem more interested in sound quality and features. The A 21 and A 51 amplifiers are both loaded with usable features above and beyond most other amplifiers in today's market.
The understated look of the A 21 / A 51s subtle yet empowered front panel implies a need for a space aged protective shell that contains a powerful yet precious cargo. For example the "P" on the top of the front face glows red to indicate that the unit has AC power as does the "Halo" insignia around the power button which accents the power button with its soft blue glow. Once the power is turned on the soft blue changes to a brighter blue after all circuitry has been initialized. In the center bottom of the front face are the two indicators that verify proper functionality of each channel by glowing with a different shade of blue. On the right bottom is another indicator that glows red if the unit overheats with a redundancy portrayal from the "Halo" insignia that also switches to red.
