Description
The Studiomaster HX4-600 is a compact and efficient 4-channel Class-D power amplifier designed for professional audio installations, live sound, and commercial AV systems. Delivering up to 4 x 255W at 4Ω within a lightweight 1U rack format, it provides a highly flexible and space-efficient amplification solution for multi-zone environments.
As part of the Studiomaster HX Series, the HX4-600 combines reliable power output, low impedance stability, and energy-efficient performance, making it well suited to hospitality venues, retail environments, corporate AV systems, and portable audio setups.
Four Channels of Flexible Amplification
The HX4-600 delivers:
- 4 x 255W @ 4Ω
- 4 x 150W @ 8Ω
- 4 x 435W @ 2Ω
- Bridge mode up to 2 x 870W @ 4Ω
This multi-channel configuration allows multiple speaker zones or circuits to be powered from a single amplifier, reducing rack space and simplifying system design.
It is ideal for:
- Multi-zone hospitality systems
- Retail and commercial audio
- Corporate and conference environments
- Education facilities
- Small touring and rental systems
Stable Low Impedance Operation
The HX4-600 is stable down to 2Ω, enabling multiple loudspeakers to be connected per channel without compromising performance.
This provides:
- Greater system flexibility
- Increased speaker loading per channel
- Efficient scaling without additional amplifiers
This makes it particularly effective for installations where multiple speakers are required per zone.
Compact 1U Design for Installation Efficiency
Housed in a compact 1U rack chassis, the HX4-600 delivers four channels of amplification in a minimal footprint.
This enables:
- Efficient use of rack space
- Simplified installation in equipment cabinets
- Reduced system footprint for multi-zone setups
Its lightweight design also makes it suitable for portable and rental applications.
High Efficiency Class-D Performance
Utilising Class-D amplification technology, the HX4-600 delivers high output with reduced power consumption and heat generation.
Key benefits include:
- Energy-efficient operation
- Reduced thermal load
- Reliable performance in continuous-use environments
- Lower operating costs
The amplifier also features power factor correction (PFC) and a universal 90–250V power supply, ensuring stable performance across varying mains conditions.
Flexible Operating Modes
The HX4-600 supports multiple operating configurations:
- Stereo mode for independent channel operation
- Parallel mode for identical signal distribution
- Bridge mode for increased output power
This flexibility allows system designers to adapt the amplifier to both distributed and higher-output applications.
Professional Connectivity and Integration
The HX4-600 is equipped with industry-standard connectivity for seamless integration into 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 dependable operation, the HX4-600 includes a full protection suite:
- Thermal protection
- Overload and short-circuit protection
- DC fault protection
- Output limiter to prevent clipping
- LED indicators for real-time status monitoring
A variable-speed fan ensures efficient cooling during sustained operation.
Ideal Applications
The Studiomaster HX4-600 is widely used across professional audio environments:
- Bars, pubs, and hospitality venues
- Retail and commercial installations
- Corporate AV systems
- Education facilities
- Houses of worship
- Live sound and rental systems
Its four-channel design makes it particularly suited to multi-zone and distributed audio systems.
