Studiomaster HX2-900 2-Channel 1U Digital Power Amplifier (2 x 765W @ 4 Ohms)
DETAILS
The Studiomaster HX2-900 is a high-output, two-channel digital power amplifier engineered for professional installations and live sound applications.
The Studiomaster HX2-900 is an ultra-lightweight yet extremely powerful two-channel digital amplifier in a compact 1U rackmount chassis. Part of the HX Series, it delivers maximum performance in a small footprint, making it ideal for conference venues, entertainment spaces, touring setups, and rental applications where reliability and space efficiency are critical.
Designed for demanding applications, the HX2-900 delivers up to 765W per channel at 4 ohms, with stable operation down to 2-ohm loads. Its energy-efficient design, combined with power factor correction (PFC) and a universal 90–250V power supply, ensures consistent performance across varying mains conditions.
High-Power Performance with Flexible Configuration
The HX2-900 supports stereo, parallel, and bridged operation modes, allowing integration with a wide range of loudspeaker configurations. Multiple gain modes and an integrated output limiter provide precise control and protection, making it suitable for both music reproduction and speech-focused systems.
Professional Protection and Connectivity
Featuring comprehensive thermal, overload, and DC protection, the HX2-900 ensures long-term reliability. A variable speed fan provides efficient cooling while keeping operational noise low, and front-panel LEDs clearly indicate thermal, fault, and limiter status. Balanced XLR inputs and professional speaker connectors make integration into professional audio systems straightforward and secure.
