Advanced Feedback Suppression Processor with Full LCD Display
The AFS2 Dual-Channel Advanced Feedback Suppression Processor from DBX protects your ears and audio equipment from annoying and potentially damaging audio feedback without altering your sound. The AFS2 features application-specific filter types for speech, music low, music medium, and music high. The 24 fixed or live narrow-band notch filters are capable of removing frequencies at 1/80 of an octave, ensuring an optimal frequency response without the possibility of feedback.
The front panel features the wizard function to take the guesswork out of setting up any room by incorporating an advanced feedback suppression module and providing a full LCD display for system settings and menus. Additionally, the AFS2 offers a five-segment LED for accurately monitoring input levels for each channel, while the notch filter indicator allows you to monitor the number of filters applied. Dedicated bypass buttons are included to help isolate problem channels. The rear panel offers XLR and 1/4″ inputs and outputs, both switchable between +4 and -10 dB operations. A USB port has been provided for firmware updates. The AFS2 ships with a standard IEC power cable.

Overview
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

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.
