Atlas Sound HPA1204 Overview
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.
- Ideal for clubs, house of worship systems, portable sound systems, convention centers, sports venues, hotels, and retail centers
- Four channels at 300W per channel
- 4-ohm, 8-ohm, 70V, and 100V operation
- Low-resistance, direct-coupled thermal transfer design maintains an optimal temperature across all loads and output levels
- Meets Energy Star standards, drawing just 1W of power in standby mode
- Balanced line inputs on Euroblock connectors
- Rear-panel accessory card slot for separately available Atlas HPA-DAC4 Dante four-channel digital audio interface card
- Stereo or parallel operating modes
- Selectable input sensitivity
- High-efficiency fan cooling
- Auto-sensing 100 to 240 VAC mains power supply
- Occupies 2 RU of rack space
In the Box
- Atlas Sound HPA1204 Four-Channel 1200W Commercial Amplifier (Black)
