Highlight Features
Professional Four-Channel Power Amplifier AQ-4.10
The AQ-4.10 is a high-output four-channel power amplifier developed for professional sound systems that require flexible channel distribution, stable low-impedance operation, and precise loudspeaker control. Combining Class D amplification with a transformer-based power module, it can drive full-range speakers, stage monitors, line arrays, and subwoofers from a single rack-mounted unit. The amplifier is suitable for touring systems, live events, clubs, auditoriums, restaurants, and permanent sound installations.
Products Description
- Four-channel power architecture: Four independent amplifier channels enable multiple loudspeaker zones or system components to be powered from one compact unit.
- High-output performance: Delivers up to 4 × 4000 W at 2 Ω, providing substantial power for demanding professional loudspeaker systems.
- Flexible bridge operation: Supports 16 Ω, 8 Ω, and 4 Ω bridge configurations for applications requiring higher output from paired channels.
- Efficient Class D amplification: The high-efficiency circuit reduces power loss and heat generation while maintaining strong dynamic output.
- Exceptional loudspeaker control: A damping factor above 5000 supports tighter bass response and more accurate driver movement.
- Wide frequency reproduction: The 20 Hz–22 kHz response range provides balanced reproduction from deep low frequencies to detailed high-frequency content.
- Selectable input sensitivity: Settings of 0.775 V, 1 V, and 1.5 V simplify integration with mixers, processors, and system controllers.
- Professional balanced inputs: Active balanced XLR connections help maintain signal integrity and reduce noise over long cable runs.
- Comprehensive protection: Integrated protection covers short circuits, DC faults, overload, overheating, ultrasonic signals, RF interference, and peak voltage limiting.
- Professional rack installation: The durable chassis and compact 2U-style dimensions support installation in touring racks and fixed equipment rooms.
