MB Quart QA1-900.6D Q-Series 900 Watt 6 Channel DSP Amplifier with Integrated Bluetooth DSP Control
SKU: MBQ-QA1-900.6DSP
Category: Q-Series Amplifier / DSP
The MB Quart QA1-900.6D Q-Series 6 Channel DSP Amplifier is a high-performance full-range Class D amplifier designed for precision tuning, clean power delivery, and advanced system control. Engineered for universal installation, it combines efficient amplification with a fully integrated digital signal processor (DSP), making it suitable for factory system upgrades and custom aftermarket audio builds.
With 900 watts maximum power output and six independent channels, this amplifier provides flexible system configuration options including multi-speaker setups or bridged operation for subwoofer integration. Its DSP architecture allows full control over crossover points, EQ, phase alignment, and signal shaping through PC, iOS, or Android applications, enabling professional-level tuning without external processors.
The built-in Bluetooth connectivity provides direct wireless control of DSP settings, simplifying real-time audio adjustments during installation and tuning. High- and low-level inputs ensure compatibility with both factory head units and aftermarket sources, while the Q-Stasis preamp stage is designed to reduce incoming signal noise for improved clarity and dynamic range.
