dbx DriveRack 260 - 2-Input/6-Output Loudspeaker Management System with Feedback Elimination and LCD Display in Black Finish

The dbx DriveRack 260 is a sophisticated 2-input/6-output loudspeaker management system designed to deliver comprehensive audio processing and control for both live sound and installed systems. With its powerful DSP modules and multiple control surfaces, the DriveRack 260 offers a complete solution for optimizing sound quality and managing audio systems effectively. It is ideal for applications that demand high performance, flexibility, and ease of use.

The DriveRack 260 is equipped with two inputs and six outputs, all featuring XLR connectors. This configuration supports a variety of audio setups and ensures robust signal handling. Each input channel offers a choice between a 9-band parametric equalizer or a 28-band graphic equalizer, allowing for precise tone shaping and frequency adjustments. Additionally, each input channel includes two selectable insert processors that offer options such as notch filtering, classic dbx compression, auto gain control, sub-harmonic synthesis, and the innovative Advanced Feedback Suppression (AFS) for managing feedback effectively.

For signal alignment and time adjustments, the DriveRack 260 provides up to 2.7 seconds of delay. This feature is crucial for optimizing audio synchronization and achieving precise alignment in complex audio setups. The system also includes comprehensive bandpass, crossover, and routing configurations, offering Bessel, Butterworth, and Linkwitz-Riley filter topologies. This flexibility ensures that the system can be tailored to meet the specific requirements of various audio environments.

Each output channel of the DriveRack 260 is equipped with parametric equalization and dbx PeakStopPlus limiting, ensuring that audio is delivered with maximum clarity and minimal distortion. The system includes a real-time analyzer (RTA) for live sound applications, providing valuable feedback for sound engineers. Additionally, the system features a pink noise generator and a setup wizard that streamlines the setup process by providing JBL speaker and Crown power amplifier tunings. This wizard function simplifies configuration, making it accessible even for users with limited experience.

The DriveRack 260 also offers robust control options. It includes RS-232 PC GUI control for detailed management and configuration, as well as wall panel control inputs for easy access to logic and volume adjustments. The security lockout feature ensures that settings are protected from unauthorized changes, maintaining the integrity of the audio system.

In terms of audio performance, the DriveRack 260 employs dbx Type IV conversion technology, providing exceptional dynamic range and audio fidelity. The system delivers a dynamic range of over 114dB A-weighted and 119dB A-weighted with Type IV dynamic range. The frequency response extends from 20Hz to 20kHz with a precision of +/- 0.5dB, and the total harmonic distortion plus noise (THD+N) is a mere 0.002% at +4dBu, ensuring high-quality audio reproduction. The interchannel crosstalk and crosstalk from input to output are both greater than 100dB, maintaining signal integrity across the system.

Overall, the dbx DriveRack 260 offers a powerful and versatile solution for managing audio systems. Its advanced processing capabilities, flexible control options, and user-friendly features make it an essential tool for achieving optimal sound quality and performance in various settings.
