THERE IS ONLY ONE.
This power amplifier is in good condition. It has passed our 8-point functional test, with 2 item(s) not applicable to this unit. Note: The unit is in good working order with all functions performing as expected. Cosmetically, there are quite a few surface marks and scratches throughout, particularly on the top of the amplifier. The rack-mount ears on the sides are also slightly bent out of shape, but the unit still fits onto a rack without issue. Please review all photos carefully, as they provide an accurate representation of the cosmetic condition of the product.
The ProSound 800 is a 2U rack-mount professional power amplifier built around a Class AB design, prioritising reliability and low distortion. It delivers 200W per channel into 8Ω in stereo, 300W per channel into 4Ω, or 400W into 8Ω in bridge mono - making it a flexible choice for a range of live sound applications. Connections on the rear panel include balanced XLR and unbalanced ¼-inch jack inputs, plus three Speakon output connectors covering Channel A, Channel B, and bridge mode. A variable-speed brushless fan keeps thermals in check, while comprehensive protection circuitry guards against over-current, short circuit, over-temperature, DC, and high-frequency faults. The front panel features dual VU meters, status indicators, and a reset switch.
A great opportunity to own a ProSound 800 at this price point.
