DBX DriveRack 260 is a digital signal processor (DSP) that provides comprehensive control over a range of audio parameters for loudspeaker management in live sound reinforcement applications. It is designed to be used in conjunction with amplifiers and loudspeakers to optimize sound quality and prevent damage to loudspeakers.
Some of the features of the DBX DriveRack 260 include:
Feedback suppression: The DriveRack 260 has an advanced feedback suppression algorithm that can detect and suppress feedback frequencies quickly and accurately.
Crossover: The DriveRack 260 has a 2-way stereo or 3-way mono crossover with selectable filter types (Butterworth, Bessel, and Linkwitz-Riley) and slopes (up to 48dB/octave).
EQ: The DriveRack 260 has a 8-band parametric EQ for each input and output channel. It also has a graphic EQ with up to 31 bands for each input and output channel.
Dynamics processing: The DriveRack 260 has a compressor, limiter, and gate for each input and output channel.
Auto-EQ: The DriveRack 260 can automatically EQ a room using its RTA (Real-Time Analyzer) feature.
Control: The DriveRack 260 can be controlled via its front panel or via a computer using its USB or RS-232 ports. It also has MIDI input and output.
One of the key features of the DriveRack 260 is its ability to act as a loudspeaker management system. This means that it allows you to control various aspects of your speaker setup, including EQ, crossover, compression, limiting, and delay. This level of control can help you achieve a more consistent and high-quality sound across different venues and environments.
In terms of its EQ capabilities, the DriveRack 260 offers both graphic and parametric equalization options. Graphic EQ allows you to adjust the levels of specific frequency bands, while parametric EQ allows you to adjust the center frequency, bandwidth, and gain of each individual EQ band. This level of control can be especially useful for removing problematic frequencies or boosting certain frequencies to achieve a desired sound.
The DriveRack 260 also includes a built-in crossover, which allows you to split your audio signal into separate frequency ranges for different speakers or subwoofers. This is important because different speakers are designed to handle different frequency ranges, and using a crossover can prevent frequencies from being sent to speakers that can’t handle them, which can result in distortion or damage.
In addition to its EQ and crossover capabilities, the DriveRack 260 also includes compressor/limiter functions. These functions allow you to control the dynamic range of your audio signal, which can help prevent clipping and distortion, and ensure that your audio stays within a certain level range.
Finally, the DriveRack 260 includes delay functions, which allow you to compensate for any delays that may be introduced by your audio system or venue. This can be especially useful in larger venues or outdoor settings where sound travels at different speeds, causing audio signals to arrive at different times.
Its ability to control EQ, crossover, compression, limiting, and delay can help you achieve a more consistent and high-quality sound across different venues and environments. This feature can make your event stand out and memorable.
Overall, the DBX DriveRack 260 is a powerful tool for optimizing sound quality and preventing loudspeaker damage in live sound reinforcement applications. It provides a range of features and can be controlled via multiple methods, making it a versatile option for audio professionals.
