Description

The Studiomaster HX2-700 is a powerful and compact 2-channel Class-D power amplifier designed for professional audio installations, live sound, and commercial AV systems. Delivering 2 x 595W at 4Ω in a lightweight 1U rack format, it provides an excellent balance of performance, efficiency, and flexibility for medium to high-demand audio environments.

Part of the Studiomaster HX Series, the HX2-700 is engineered to deliver consistent output, stable operation under low impedance loads, and reliable long-term performance, making it a strong choice for installers and system integrators.

High Output Power in a Compact 1U Design

The HX2-700 delivers:

• 2 x 595W @ 4Ω
• 2 x 350W @ 8Ω
• 2 x 1015W @ 2Ω
• Bridge mode up to 2030W @ 4Ω

This level of output makes it ideal for:

• Bars, pubs, and hospitality venues
• Retail and commercial audio systems
• Corporate AV and conference spaces
• Education environments and lecture spaces
• Portable PA and rental systems

Despite its output capability, the amplifier maintains a compact 1U chassis, allowing efficient use of rack space in both fixed and mobile installations.

Stable Low Impedance Operation

The HX2-700 is stable down to 2Ω, enabling multiple loudspeakers to be connected per channel where required.

This allows:

• Greater system flexibility
• Increased speaker loading per channel
• Efficient system scaling without additional amplifiers

Combined with multiple operating modes, the amplifier adapts easily to different installation requirements.

Flexible Operating Modes

The HX2-700 supports:

• Stereo mode – independent channel operation
• Parallel mode – identical signal across both channels
• Bridge mode – increased output for a single load

This flexibility enables system designers to optimise amplifier performance based on application, whether for distributed audio or higher output zones.

High Efficiency Class-D Performance

Utilising Class-D amplification, the HX2-700 delivers high output with improved efficiency and reduced heat generation.

Key benefits include:

• Lower power consumption
• Reduced thermal load
• Lightweight construction
• Reliable continuous operation

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

Professional Connectivity and Integration

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

• Balanced XLR inputs for clean 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

The HX2-700 includes a full protection suite to ensure safe and reliable operation:

• Thermal protection
• Overload and short-circuit protection
• DC fault protection
• Output limiter to prevent clipping
• Status indicators for thermal, fault, and limiter conditions

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

Installation-Ready Design

Housed in a standard 1U 19-inch rack format, the HX2-700 is designed for straightforward installation into AV racks and equipment cabinets. Its lightweight construction (approx. 5kg) makes it equally suitable for portable and touring applications.

Ideal Applications

The Studiomaster HX2-700 is widely used across professional audio environments:

• Hospitality venues and bars
• Retail and commercial installations
• Corporate AV systems
• Education facilities
• Houses of worship
• Live sound and rental systems

Its combination of power and compact design makes it particularly suited to medium-sized systems requiring higher output than entry-level amplifiers.
