- Equalization
- Crossover
These functions allow the amplifier module to be optimized for different loudspeaker drivers, cabinet designs, crossover configurations, and sound reinforcement applications.
Compact and Lightweight Design
Despite its high output power, the H2800 measures only 332 × 160 × 100 mm and has a net weight of 2.75 kg. Its compact format makes it suitable for powered speaker cabinets where installation space and overall system weight are limited.
By combining amplification, power conversion, and DSP processing in one integrated module, the H2800 simplifies cabinet assembly and reduces the need for separate electronic components.
High-Efficiency Cooling
The H2800 features an efficient thermal-management design that helps dissipate operating heat and maintain stable amplifier performance during extended professional use.
Its high-efficiency Class D topology also reduces unnecessary power loss and heat generation compared with conventional amplifier designs.
Flexible Operating-Voltage Options
The H2800 is available with different power-supply versions for international markets:
- 110V version: 90–135V AC
- 220V version: 180–265V AC
- Optional PFC version: 90–265V AC
The optional wide-voltage PFC version is recommended for touring systems, rental equipment, and export markets where mains voltage may fluctuate. Its broad operating range provides improved compatibility with different regional power grids and demanding mobile sound applications.
Protection and Reliability
The H2800 incorporates multiple protection functions to help maintain stable operation and protect the amplifier and connected loudspeaker components.
Protection functions include:
- Short-circuit protection
- DCP protection
- Overvoltage protection
- Undervoltage protection
- Overcurrent protection
- Overtemperature protection
