Description
The Studiomaster HX2-900 is a high-output 2-channel Class-D power amplifier designed for professional audio installations, live sound, and commercial AV environments. Delivering 2 x 765W at 4Ω within a compact 1U rack format, it provides a powerful and efficient amplification solution for medium to large-scale systems requiring strong performance and flexibility.
As part of the Studiomaster HX Series, the HX2-900 combines high power density, reliable low impedance operation, and energy-efficient design, making it an ideal choice for installers and system integrators.
High Power Output for Demanding Applications
The HX2-900 delivers:
- 2 x 765W @ 4Ω
- 2 x 450W @ 8Ω
- 2 x 1300W @ 2Ω
- Bridge mode up to 2600W @ 4Ω
This level of output makes it particularly suitable for:
- Bars, pubs, and hospitality venues
- Retail and commercial audio systems
- Corporate AV and conference environments
- Education and lecture spaces
- Live sound and rental applications
Its high power capability ensures consistent audio performance across demanding environments and larger speaker systems.
Stable Low Impedance Operation
The HX2-900 is stable down to 2Ω, allowing multiple loudspeakers to be connected per channel without compromising performance.
This enables:
- Greater flexibility in system design
- Increased speaker loading per channel
- Efficient scaling without additional amplifiers
This makes it well suited to both installation and portable audio systems.
Flexible Operating Modes
The amplifier supports multiple operating configurations:
- Stereo mode for independent channel operation
- Parallel mode for identical signal distribution
- Bridge mode for increased output to a single load
These options provide system designers with the flexibility to adapt the amplifier to a wide range of applications.
High Efficiency Class-D Design
Utilising Class-D amplification technology, the HX2-900 delivers high output with reduced energy consumption and heat generation.
Key benefits include:
- Energy-efficient operation
- Reduced thermal load
- Compact and lightweight construction
- Reliable performance in continuous-use environments
The amplifier also features power factor correction (PFC) and a universal 90–250V power supply, ensuring stable performance across varying power conditions.
Professional Connectivity and Integration
The HX2-900 is equipped with industry-standard connectivity for seamless integration into professional AV systems:
- Balanced XLR inputs for clean signal transmission
- Professional speaker output connectors
- Multiple gain settings for system matching
This ensures compatibility with mixers, DSP processors, and other professional audio equipment.
Comprehensive Protection and Reliability
Designed for demanding environments, the HX2-900 includes a full protection suite:
- Thermal protection
- Overload and short-circuit protection
- DC fault protection
- Output limiter to prevent clipping
- LED indicators for thermal, fault, and limiter status
A variable-speed fan ensures efficient cooling while maintaining low operational noise.
Compact 1U Installation Format
Despite its high output capability, the HX2-900 is housed in a compact 1U rack chassis, making it ideal for installations where space is limited.
- Height: 1U (44mm)
- Weight: approx. 5kg
This allows for efficient rack integration in both fixed installations and mobile systems.
Ideal Applications
The Studiomaster HX2-900 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 high output and compact design makes it particularly suited to systems requiring more power than entry and mid-tier amplifiers.
