| More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 234xs 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 234xs 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 234xs 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 234xs 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.

applications; there is also a simple analog input buss that allows inputs to be sent from one
unit to the next for unit and job scalability. The 640 and 641 provide every necessary processing
tool, from the input processing like gain control and EQ available on all inputs to highly sophisticated
and specific functions such as selectable paging microphone processing including Gating,
De-Essing, Auto Gain Control, Compression and Feedback Suppression. The heart of the
ZonePro products is the Routing module that provides of course Primary Source Selection
but also Source Ducking for Paging and Priority Override. The outputs also offer a wealth of
processing designed for commercial applications like our patent-pending AutoWarmth? function
that was co-developed with JBL to provide natural low frequency extension at any signal level.
Each output also offers EQ, Bandpass and Crossover filters, Limiting and Delay for system
optimization. With the ZonePro? every tool is at your disposal to maximize the response of
your system.
Beyond processing, the ZonePro? products offer multiple forms of control to further extend the
versatility of your system. From easy-to-use wall panel Zone Controllers for standard end-user
functions like source select and volume control to advanced system control including a built-in
Real Time Clock that can provide programmable system changes throughout the day or week.
For system setup and monitoring the ZonePro Designer software provides an intuitive interface
and a speedy setup Wizard for configuring and editing all system parameters.

| 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.
