dbx DriveRack PA2 - 2-Input/6-Output Loudspeaker Management System with Feedback Elimination and LCD Display in Black Finish

The dbx DriveRack PA2 is a state-of-the-art 2-input/6-output loudspeaker management system designed to provide comprehensive audio processing and optimization for live sound and installed applications. As the latest evolution in the DriveRack series, the PA2 integrates advanced features and technologies to enhance performance, flexibility, and user control, making it a valuable tool for audio professionals seeking superior sound quality and system management.

Featuring 24-bit A/D and D/A converters, the DriveRack PA2 ensures high-fidelity audio conversion and processing. Its 48 kHz/32-bit floating-point processing, coupled with dbx's proprietary Type IV conversion system, delivers exceptional audio clarity and dynamic range. The system provides up to 123 dB of dynamic range with transient material, ensuring detailed and accurate audio reproduction. The internal processing utilizes 32-bit floating-point technology, allowing for precise and versatile signal manipulation.

The DriveRack PA2 excels in loudspeaker management with a suite of advanced features. It includes dbx's renowned AutoEQ for fast and accurate room equalization, using frequency sweeps rather than pink noise to achieve precise results. This updated AutoEQ allows for up to four measurements, offering an efficient and non-intrusive automatic EQ experience. The enhanced Advanced Feedback Suppression (AFS) algorithm is faster and more effective at eliminating feedback while preserving the integrity of the system's tone.

With two XLR inputs and six XLR outputs, the DriveRack PA2 supports versatile audio configurations. Each input channel is equipped with a 31-band graphic EQ, while stereo 8-band parametric EQs are available for output tuning. The system also includes a subharmonic synthesizer, classic dbx compression, and stereo PeakPlus output limiters to ensure optimized sound and system protection. Pre-crossover delay functionality allows for alignment of the sound system to the stage backline, enhancing audio coherence and synchronization.

For real-time monitoring and adjustment, the DriveRack PA2 features a bright, easy-to-read LCD display, front-panel XLR RTA mic input with 15V phantom power, and front-panel output mute buttons. The system also includes storage memory for up to 75 user presets, allowing for quick recall of custom settings. Additionally, a network control feature via the free DriveRack PA2 control application for iOS, Android, Mac, and Windows devices enables remote configuration and adjustment from anywhere in the venue, offering unprecedented convenience and flexibility.

The DriveRack PA2's advanced algorithms support various crossover configurations, including full range, 2-way, and 3-way systems. It also offers stereo output driver alignment delays, ensuring precise audio alignment for multi-way systems. The real-time analyzer (RTA) and white/pink noise generator assist in live sound applications, providing valuable tools for sound engineers to fine-tune their systems.

Overall, the dbx DriveRack PA2 represents a significant advancement in loudspeaker management technology, combining powerful processing capabilities, intuitive user interfaces, and flexible control options. Its comprehensive feature set and user-friendly design make it an essential tool for achieving exceptional sound quality and efficient system management.
