Starting in May 2003, the 4.24C has additional input and output parametric/shelf filters, 48dB slope HPF and LPF optionsand increased security levels.
Four Inputs and Eight Outputs coupled with a user interface so easy you won’t even need the manual to set up your system, the Protea System II 4.24C Digital Crossover/System Processor has all the audio processing tools needed for precise crossover and sound control. Each input allows you to control gain, delay and six parametric, low or high shelf filters. In addition to setting crossover frequencies, each output may be assigned to any one or a combination of inputs, allows you to program four parametric, low or high shelf filters, delay for time delay adjustments, output gain, reverse polarity and a compressor/limiter for speaker protection. All this in a one rack space with XLR input and output connections. You may also program and control the 4.24C with Ashly’s Protea System Software (WindowsTM 95, 98, 2000, XP and NT platforms), MIDI or SIA-Smaart software. In all, the Protea 4.24C is a powerful tool for use in fixed installation and live sound applications.

The VENU360 provides all the processing and flexibility you need between your mixer and amplifiers to optimize and protect your loudspeakers. With the latest advancements in dbxʼs proprietary AutoEQ and AFS algorithms, additional input channels, ethernet control via an Android, iOS, Mac, or Windows device, and updated wizards, the DriveRack VENU360 continues the DriveRack legacy of great-sounding, powerful, and affordable loudspeaker management processors, for a whole new generation.
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.

With 6 inputs and 4 outputs the dbx ZonePro? 640 and 641 provide flexible signal routing,
powerful DSP processing and multiple control interfaces for Commercial Audio applications.
Designed to offer superior system sonic performance and flexibility, the 640/641 deliver the
highest quality tools available. Even the input and outputs connectors were chosen for their
standard usage and reliability. The ZonePro products offer Euroblock connectors for balanced
signals and RCA connectors for interfacing with consumer equipment often used in commercial
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.
The ZonePro? 640 and 641 will take your Commercial Audio system to the next level with advanced
processing, versatility and control.
