Four Channels of High Output Amplification
The HX4-1000 delivers:
- 4 x 425W @ 4Ω
- 4 x 250W @ 8Ω
- 4 x 725W @ 2Ω
- Bridge mode up to 2 x 1450W @ 4Ω
This multi-channel output allows multiple speaker zones or circuits to be powered from a single amplifier, reducing rack space and simplifying system design.
It is ideally suited to:
- Hospitality venues and bars
- Retail and commercial audio systems
- Corporate AV and conference environments
- Education facilities
- Live sound and rental applications
Stable Low Impedance Operation
The HX4-1000 is stable down to 2Ω, allowing multiple loudspeakers to be connected per channel without compromising performance.
This enables:
- Flexible speaker configurations
- Increased system scalability
- Efficient use of amplifier channels
Combined with its high output capability, this makes it suitable for both installation and portable audio systems.
Compact 1U Design for Efficient Installation
Housed in a standard 1U rack chassis, the HX4-1000 delivers four channels of amplification in a minimal footprint.
This provides:
- Efficient rack space utilisation
- Simplified installation in equipment cabinets
- Reduced system footprint for multi-zone setups
Its lightweight design also makes it suitable for touring and rental applications.
