Description

The Studiomaster HX2-300 is a compact and efficient 2-channel Class-D power amplifier designed for professional audio installations, live sound, and commercial AV systems. Delivering up to 2 x 255W at 4Ω within a lightweight 1U rack format, it provides a practical and cost-effective amplification solution for small to medium-sized environments.

As part of the Studiomaster HX Series, the HX2-300 combines reliable performance, flexible configuration, and energy-efficient operation, making it well suited to fixed installations, hospitality venues, education settings, and portable PA applications.

Compact Power for Professional Audio Systems

The HX2-300 delivers:

• 2 x 255W @ 4Ω
• 2 x 150W @ 8Ω
• 2 x 435W @ 2Ω
• Bridge mode up to 870W @ 4Ω

This output range makes it ideal for:

• Small venues and bars
• Retail and background music systems
• Corporate meeting rooms
• Education and classroom audio
• Portable PA and rental setups

Its compact footprint allows it to be installed easily in racks or mobile systems where space is limited.

Stable Low Impedance Performance

The HX2-300 is stable down to 2Ω, allowing multiple loudspeakers to be connected per channel where required.

This enables:

• Flexible speaker configurations
• Increased system scalability
• Efficient use of amplifier channels

Combined with stereo, parallel, and bridge operating modes, the amplifier can be adapted to suit a wide range of system designs.

High Efficiency Class-D Design

Utilising Class-D amplification technology, the HX2-300 delivers reliable output with reduced power consumption and heat generation.

Key benefits include:

• Energy-efficient operation
• Lower heat output for improved reliability
• Compact and lightweight construction
• Consistent performance in continuous-use environments

The HX Series also features power factor correction (PFC) and a universal 90–250V power supply, ensuring stable operation across varying power conditions.

Flexible Operating Modes

The HX2-300 supports multiple operating configurations:

• Stereo mode – independent left and right channels
• Parallel mode – identical signal sent to both channels
• Bridge mode – combined output for higher power applications

This flexibility allows system designers to tailor the amplifier to both distributed and higher-output setups.

Professional Connectivity and Integration

The amplifier is equipped with industry-standard connections for seamless integration:

• Balanced XLR inputs for low-noise signal transmission
• Professional speaker output connectors
• Multiple gain settings for accurate system matching

These features ensure compatibility with mixers, DSP processors, and other professional AV equipment.

Comprehensive Protection and Reliability

Designed for dependable operation, the HX2-300 includes a full protection suite:

• Thermal protection
• Overload and short-circuit protection
• DC fault protection
• Output limiter to prevent clipping
• Front-panel LED indicators for thermal, fault, and limiter status

A variable-speed fan provides effective cooling while maintaining low operational noise.

Installation-Ready 1U Design

Housed in a standard 1U 19-inch rack chassis, the HX2-300 is easy to install into AV racks and cabinets. Its lightweight design (approximately 5kg) makes it equally suitable for portable systems and touring applications.

Ideal Applications

The Studiomaster HX2-300 is widely used across professional audio environments:

• Bars, pubs, and hospitality venues
• Retail and commercial audio systems
• Corporate AV and meeting spaces
• Education facilities
• Houses of worship
• Portable PA and rental systems

Its combination of compact size and flexible output makes it particularly suited to entry-level and mid-sized systems.
