Rack Mount Power Amplifier 650W RH2866W

The RH2866W is a professional 2U rack-mounted power amplifier from RH-AUDIO, designed to receive low-level audio signals from a preamplifier or mixer and deliver sufficient power to drive connected loudspeakers. It is available in 350W, 450W, and 650W output configurations, supporting both 70/100-volt and 4–16 ohm load options.

Key Features:

• XLR and 6.35mm (¼”) input connectors
• Link output for daisy-chaining additional amplifiers
• Built-in protection circuits covering short circuit, overload, high temperature, and peak current limiting

System Role: The unit functions as a pure power (post-stage) amplifier, handling current amplification to drive speakers with high dynamic control and strong low-frequency performance. It is intended to be paired with a front-stage preamplifier or mixer, which handles voltage amplification, tonal shaping, and signal conditioning before passing audio to this unit.

Ideal for fixed installation in commercial PA systems, the RH2866W offers reliable, scalable amplification in a standard rack format.
