Gemini Sound XGA-4000 professional power amplifier — 2x 350W RMS at 4Ω, 700W bridged, 2U rack

The Gemini Sound XGA-4000 is a 2U power amp built for working performers, venue installs, and mobile rigs that need dependable output show after show. You get 2x 350W RMS at 4Ω stereo, pro-grade inputs and outputs, and a cooling system that keeps the amp stable through long nights. Gemini's been making gear for the stage since 1974 — this is the amp you buy when you want pro performance without the pro-tier price.

Key features

• Real power for real rooms — Enough headroom to drive a full PA without running your speakers into clipping. Works in stereo for standard two-speaker setups or bridged mono when you need to push a single high-demand cabinet.
• Stays cool, stays quiet — Front-to-rear airflow with a variable-speed fan keeps temperatures in check during long gigs and ramps down when it doesn't need to work as hard. No fan whine bleeding into quiet moments.
• Every input and output you'd expect — Balanced XLR and 1/4" inputs, unbalanced RCA, three Speakon outputs for channel A, B, and bridge, plus 5-way binding posts for banana plugs. Drop it into any rig without hunting for adapters.
• Built-in protection for your gear — Limiter, DC output, short-circuit, and thermal protection work together to keep the amp and your speakers safe when things get loud or something goes sideways at the venue.
• Status at a glance — Front-panel signal, clip, protect, and bridge LEDs plus independent volume controls for each channel. You always know what the amp's doing without pulling it out of the rack.
