Key Features & Benefits
⚡ 4-Channel Class D Power with 8500W Headroom
Four independent Class D amplifier channels each deliver 800W @ 8Ω or 1600W @ 4Ω, producing 3200W RMS @ 8Ω / 6400W RMS @ 4Ω in stereo — with peaks up to 8500W for transient-heavy program material. Bridge any two channels to drive high-power subwoofers or full-range cabinets on the most demanding live shows.
📦 1U Metal Rack Chassis — Built for the Road
The slim 1U all-metal rack-mount chassis is built for daily transport. Front-panel individual channel level controls and Protect / Clip / Signal LEDs give you instant feedback at front of house, while the rugged steel enclosure stands up to truck-pack, flight-case and fixed-install environments.
🔌 SpeakON + XLR I/O — Universal System Compatibility
Balanced XLR line-level inputs pair with Neutrik-compatible SpeakON speaker outputs for secure, locking connections. Switchable Mono / Stereo / Bridge modes let you reconfigure the amp for 2-channel tops, bi-amped mains, mono subs, or a 4-zone distributed system — all from a single 1U unit.
🛡️ Full-Stage Protection Circuitry
Built-in DC, short-circuit, thermal, overheat and overcurrent protection guard both the amplifier and your speakers. Per-channel Protect / Clip / Signal LED indicators make troubleshooting fast, and the amplifier automatically mutes outputs on fault detection — protecting your rig and your audience.
🌬️ Class D Efficiency + Smart Variable-Speed Cooling
A high-efficiency switch-mode power supply (SMPS) and Class D output stage deliver serious power in a lightweight, cool-running package. Variable-speed fans ramp up only when needed, keeping the amp quiet for theater and broadcast — yet cool enough for outdoor festival duty in summer heat.
