The LD DS2.1 is a universal 3-channel DSP controller for 2.1 loudspeaker systems with 24-bit processing and convenient front panel operation providing easy setup and high quality audio performance.

Designed for live sound and fixed applications the rack mountable unit offers extensive parameter control of its EQ, crossover, delay and limiter functions. The LD DS2.1 features a 3-band parametric EQ with adjustable Q and high shelf / low shelf selection. The crossover includes Butterworth, Bessel and Linkwitz-Riley filters with 6 dB to 24 dB slopes. Delay time is adjustable to a maximum of 12.5 ms for each of the three outputs and the limiter provides independent threshold and hold time setting for the L / R and subwoofer channels.

A backlit 2 x 16 LCD and jog wheel allow for quick parameter adjustment and recall of up to 6 presets. Also provides real time level meter. The rear panel features XLR connectors for left and right input, left and right plus sub XLR outputs and a USB port. Software and a power cord is included.

The DX 4008 is a complete 4 input - 8 output digital loudspeaker management system designed for the touring or fixed sound installation markets.

The absolute latest in available technology is utilized with 32-bit (40-bit extended) floating point processor and high performance 24-bit Analog Converters. The high-bit DSP prevents noise and distortion induced by truncation errors of the commonly used 24-bit fixed-point devices. A complete set of parameters include I/O levels, delay,polarity, 6 bands of parametric EQ per channel, multiple crossover selections and full function limiters. The DX 4008 can be controlled or configured in real time on the panel or with the intuitive PC GUI accessed via the RS 232 interface. Software upgrade for CPU and DSP via PC keeps the device current with newly developed algorithms and function once available. Multiple setup storage and system security complete this professional package.

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. XLR balanced ins and outs Mode switches for mono 4-way or stereo 2-way/3-way operation Low frequency summed (subwoofer) output x10 range switch on both channels 40Hz high pass (low cut) filter both channels Phase reverse switch on all outputs Individual level controls on all outputs 24dB per octave Linkwitz-Riley filters (the professional standard) Stereo/Mono status LEDs indicate the selected mode dbx® 2 year parts and labor as standard CSA NRTL/C approved CE compliant

With 12 inputs and 6 outputs and Ethernet control the dbx ZonePro? 1260 and 1261
are the newest members of the ZonePro? family providing a complete suite of signal
processing and control for Commercial Audio applications.
Designed to offer superior system sonic performance and flexibility, the 1260/1261 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 1260 and 1261 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 addition of
Ethernet control means that not only will it work with standard network equipment, but it can also
be accessed from remote dialup locations or from wireless access points.
The ZonePro? 1260 and 1261 will take your Commercial Audio system to the next level with advanced
processing, versatility and control.
