| Content | Starting in May 2003, the 4.24D has additional input and output parametric/shelf
filters, 48dB slope HPF and LPF options and increased security levels.
Four Inputs and Eight Outputs allow you to distribute audio from a variety of sources to multiple locations, the Protea System II 4.24D Digital Distribution System Processor has all the audio processing tools needed for precise crossover and sound control.
Each input allows you to control gain, six parametric, low or high shelf filters and the ability to assign any input to any output. In addition to setting crossover frequencies, each output allows you to program four parametric, low or high shelf filters, delay of up to 682ms, output gain, reverse polarity and a compressor/limiter for speaker protection.
All this is in one rack space with euroblock type input and output connections. Programming the Protea 4.24D is straight-forward using a PC and Ashly's Protea System Software (WindowsTM 95, 98, 2000, ME, XP and NT platforms).

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.

| 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.

Providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115 dB, the DSP 244 sets new standards for digital loudspeaker controllers and processors. The DSP 244 is an universal Digital Sound System Processor that provides 2 inputs and 4 outputs; plus internal summing of the inputs 1 and 2. Via matrix it is possible to assign the outputs to any input or to the sum of the inputs. It is further possible to establish the following configurations: Stereo or Dual 2-Way systems, 3-Way + Direct and 4-Way systems, each with Mono Subchannel, but also full range systems. High and low-pass filters are provided for the frequency crossover functions in all operation modes. The selection includes Linkwitz-Riley, Butterworth and Bessel type filters with switchable slopes between 6, 12, 18 and 24 dB/oct. A huge number of additional filters offers extremely flexible correction of the frequency response. Each input incorporates a 5-band equalizer, allowing to assign high and low-pass, high and low-shelving or parametric peak-dip filters to its individual filter sections. Next to the frequency crossover filters, four additional filters are employed in each output channel, which also can be set to work as high or low-pass, high or low-shelving filters, parametric peak-dip filters, or all-pass filters. Additional filtering is provided through 2. order high-passes for the realization of B-6 alignment, or special LPN-filters (Low-Pass Notch filters) for correcting the frequency and phase responses of optimally vented woofer cabinets. Each channel additionally provides a delay, a polarity switch, a programmable level control and a digital compressor / limiter while the master delays are located in the input channels.
