Power Amplifier AQ Series (AQ-2.15 / AQ-2.20)
Highlight Features
Professional Power Amplifier Series – AQ-2.15 / AQ-2.20
The AQ Series professional power amplifiers are engineered for large-scale sound systems that require high continuous output, precise loudspeaker control, and dependable operation under demanding loads. Combining Class D amplification with a transformer-based power supply, the AQ-2.15 and AQ-2.20 deliver powerful dynamics across 2 Ω, 4 Ω, and 8 Ω configurations. They are suitable for line array systems, subwoofers, touring productions, clubs, auditoriums, live events, and permanent professional audio installations.
Products Description
- High-output Class D amplification: Delivers substantial stereo and bridge-mode power for driving professional full-range loudspeakers, line arrays, and high-power subwoofers.
- Stable low-impedance operation: Supports loads down to 2 Ω per channel, providing greater flexibility when operating multiple loudspeakers from one amplifier.
- Exceptional loudspeaker control: A damping factor above 5000 helps control driver movement accurately for tighter bass and improved transient response.
- Wide audio frequency response: The 20 Hz–22 kHz operating range supports deep low frequencies, articulate midrange, and detailed high-frequency reproduction.
- Flexible input sensitivity: Selectable 0.775 V, 1 V, and 1.5 V settings simplify integration with different mixers, processors, and system controllers.
- Professional balanced connectivity: Active balanced XLR inputs maintain reliable signal transmission and help reduce unwanted noise over long cable runs.
- Versatile speaker outputs: Dual Neutrik NL4-compatible ports and binding posts support secure connection to different professional loudspeaker systems.
- Comprehensive circuit protection: Integrated protection covers short circuits, DC faults, overload, overheating, ultrasonic signals, RF interference, and peak voltage limiting.
- Efficient thermal performance: The robust chassis and cooling architecture support reliable continuous operation during concerts, touring, and fixed installations.
- Clear operating-status monitoring: Front-panel indicators provide convenient visual monitoring of amplifier activity and system condition.
