Studiomaster HX2-500 2-Channel 1U Digital Power Amplifier (2 x 425W @ 4 Ohms)
DETAILS
The Studiomaster HX2-500 is a compact, high-performance two-channel digital power amplifier designed for professional audio use.
The Studiomaster HX2-500 is an ultra-lightweight yet powerful two-channel digital power amplifier housed in a compact 1U rackmount chassis. Part of the HX Series, it delivers reliable, efficient power while maintaining a small footprint, making it ideal for installations, conferences, entertainment venues, and smaller touring or rental systems.
Engineered for demanding applications, the HX2-500 delivers up to 425W 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.
Flexible Power and Operation Modes
The HX2-500 supports stereo, parallel, and bridged modes, allowing integration with a wide range of loudspeaker configurations. Multiple gain modes and an integrated output limiter provide precise level control and protection, making the amplifier suitable for both music and speech applications.
Comprehensive Protection and Professional Connectivity
Featuring full thermal, overload, and DC protection, the HX2-500 ensures long-term reliability. A variable speed fan provides efficient cooling while keeping operational noise to a minimum, and front-panel LEDs clearly indicate thermal, fault, and limiter status. Balanced XLR inputs and professional speaker connectors allow easy integration into any professional audio system.
