The XPA HC-1 is a true monoblock power amplifier featuring a single high-power XPAGen3 amplifier module powered by its own dedicated Switch Mode Power Supply (SMPS). The chassis is the same height and depth as other XPA Gen3 models but half as wide making it easy to position the HC-1 near each of your main speakers or arrange several of them side-by-side in your equipment rack. Emotiva has kept the sides clear of ventilation slots so theres no problem setting them directly next to each other. If youre looking for a single amplifier to power your centre channel a pair of monoblocks to power your main speakers or a full set to power a surround sound system then the XPA HC-1 is probably the perfect amplifier for you.
