JAM Systems 2-Channel Power Amp [2 x 850W]

High-Power Professional Audio Amplifier

Designed for demanding live sound and fixed installation applications, this professional power amplifier delivers exceptional output power, clarity, and long-term reliability. Built in a rugged 2U rack-mount chassis with advanced thermal management, it is ideal for touring systems, venues, and PA installations that require consistent, high-quality performance.

The amplifier delivers 2 × 500W at 8Ω and 2 × 850W at 4Ω, providing ample headroom to drive professional loudspeakers with confidence. A wide 20Hz–20kHz frequency response with tight ±0.3dB tolerance ensures accurate and natural sound reproduction across the full audible spectrum.

Engineered for clean and precise audio, the amplifier features ultra-low distortion (≤0.05% THD+N), a signal-to-noise ratio greater than 100dB, and a high damping factor ≥1500 for excellent loudspeaker control, especially in low-frequency performance. Flexible operating modes including Stereo, Parallel Mono, and Bridge allow easy system integration.

Professional connectivity with balanced XLR inputs and locking loudspeaker outputs, combined with front-to-rear forced-air cooling, ensures stable and reliable operation even during continuous high-power use.

Key Highlights

  • 2 × 500W @ 8Ω / 2 × 850W @ 4Ω output power
