AtlasIED HPA4202 Dual-Channel 4800-Watt Commercial Amplifier

The HPA4202 is a dual-channel commercial amplifier built to run 70.7V/100V distributed speaker lines and low-impedance 2/4/8-ohm loads from the same chassis, using a Class I output stage that AtlasIED positions as Class D efficiency with Class AB sound quality. Front-panel level controls sit behind a security cover, and the unit supports remote turn-on plus balanced inputs with fault reporting back to a monitoring system.

Output tops out at 2 x 2100W at 70.7V/100V or 4-ohm, 2 x 2500W at 2-ohm, and 3800W bridged into 8 ohms, with an optional 2- or 4-channel Dante card for network audio input. A variable-speed cooling fan and Energy Star-rated 1-watt standby draw keep it practical to run continuously in a rack alongside other equipment.
