HPA1204 Four-Channel 1200W Commercial Amplifier (Black)
Product Description
The black Atlas Sound HPA1204 is a four-channel 1200W commercial amplifier offering 300W per channel, support for 4-ohm, 8-ohm, 70V, and 100V operation, and expandability via a separately available Dante card. By utilizing Generation II Class-D topology, this HPA Series amp delivers high power and enhanced efficiency along with sound quality akin to a Class-AB amplifier.
The switch mode, auto-sensing universal power supply ensures that a reliable output is achieved even when receiving inconsistent power voltages. Together, the power supply and output circuitry yield peak performance with a variety of speaker loads while remaining energy efficient and compact.
Detented attenuators enable easy level adjustments while their security cover prevents unwanted changes to amp gain. With fault reporting, remote turn-on functionality, and informative front-panel LED indicators, the HPA1204 is ideal for commercial distributed systems, contractor applications, houses of worship, and more.
