AtlasIED HPA4202 2-Channel x 2400W Commercial Multi-Impedance Power Amplifier

The AtlasIED HPA4202 is a high-output, dual-channel professional power amplifier ideal for both commercial 70 V/100 V distributed systems and low-impedance setups. Featuring Gen II Class I output topology, it delivers the transparency of Class AB with the efficiency of Class D. A universal, auto-sensing power supply and variable-speed fan ensure reliable performance in fluctuating environments.

Output options include 2×1200 W @ 8 Ω, 2×2100 W @ 4 Ω or 70.7 V/100 V, 2×2500 W @ 2 Ω, and bridged modes up to 4800 W. Front-panel stepped attenuators with security covers, balanced Euro-block inputs, fault reporting, remote power-on, and an accessory slot for Dante networking make it install-ready for clubs, stadiums, houses of worship, and large distributed audio applications.
