DRIVE RACK PA Complete Equalizaton & Loudspeaker Management System
The DriveRack? PA continues the legacy of DriveRack? series, which
has been created by the company that has been redefining the standard
of signal processing for more than 30 years. The DriveRack? PA was
designed with the purpose and vision of providing state-of-the-art signal
processing, while utilizing a simple and intuitive user interface. This goal
has been achieved by offering two independent channels of processing
power with a linkable 28-Band Graphic equalizer, industry-standard dbx?
stereo compressor module, feedback eliminator and the 120A Subharmonic
Synthesizer on the input, with a six channel output system that includes
parametric EQs, and Peak Plus? limiters (which are used to provide

More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 223xs Crossover you\'ll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world\'s finest processors. The 223xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 223xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 223xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs

| Behringer DCX2496 Overview
The DCX2496 ULTRADRIVE PRO from Behringer is a digital loudspeaker management system, that provides excellent audio quality, along with a comprehensive feature list. It allows for precise set-up of multiple loudspeaker arrays, suitable for live sound, fixed installations that require control of loudspeaker systems, and other contractor-installed applications.
Each of the three-inputs and six-outputs have fixed processing blocks, including gain, delay, EQ and dynamic EQ on the input channels, and gain, crossover, EQs, limiter and delays on the output side. One of the inputs can accept a stereo AES/EBU digital signal. An integrated sample rate converter assists in accepting various sample rates. Additionally, an internal input-sum signal is easily set-up.
Four different mono and stereo output operating modes are available, all with individual crossover filter types with selectable roll-off characteristics. Input and output delays allow for time adjusting signals to compensate for ambient temperature changes or for adjusting arrival time differences for individual speaker clusters. EQs can be used for both musical enhancement or for level-dependent equalization. Brick-wall limiters guarantee speaker protection.
Remote control of one or several units can be accomplished utilizing downloadable software for a Windows based computer. Set-ups can be saved to the software, or to an optional PCMCIA card for the ultimate in portability. Servo-balanced, gold-plated XLR connectors for all inputs and outputs guarantee excellent connectivity.
