Eventide "Harmonizer" effects processors have always been considered "classics" by musicians and the professional audio community. The DSP4000B+ is a single-processor, programmable, multipurpose, 24-bit/96kHz digital audio signal processors with UltraShifter capability that is targeted squarely at the broadcast and post communities. The unit is based on the DSP7000 but contains a unique set of software programs created especially for radio, TV and postproduction by sound designer Jay Rose.

Effects that would be impossible with most processors are instantly available with the DSP4000B+series. For instance, the sound of an airplane captain speaking from the cockpit, or the kid at the drive-thru window at a fast-food place. Or the sound of a TV coming from the next room, or a cellular phone. There are dozens of audio environments to choose from. Fantasy voices are just as easy. Is that your conscience talking back to you? Or your fairy godmother? Or you worst nightmare? Also sound effects and audio backgrounds are built right in including rain and thunder, the seashore, wind, a jet flying by.

Standard effects programs are also included that span the gamut of audio processing, from lush reverbs, to choruses, flangers, delays, pitch shifters, to dynamics, EQs, filters, distortions, to synthesizers, ring modulators and everything in-between. Using the DSP4000B+'s "Algorithm Construction Kit," the user can select and link together the various effects module building blocks with a virtually endless array of combinations and configurations from which to choose. For instance, one could place a pitch shift module after a reverb, or string together effects and put EQ on only the ones wanted - the user decides which modules talk to which.

For some people, UltraShifter, a very natural sounding vocal pitch shifter, is reason enough to own a DSP4000B+. The auto pitch correction preset can turn a near-great performance with some off notes, into a great performance. Most frequency and time-dependent parameters (delays, LFOs etc.) synchronize to a system tempo for ease of use. Aside from the sonic integrity, the unit provides a wide variety of input/outputs that included balanced and unbalanced analog connectors, AES/EBU and S/PDIF digital I/O, WordClock I/O, full MIDI, two pedal inputs, two relay and a serial connector.

  • Awesome and large collection of effects, designed for use in TV, broadcast and post production situations
  • User can select and link together the various effects module building blocks with a virtually endless array of combinations


Provides the industry standard pitch shifting algorithms for pitch correction, vocal harmony stacking or for post production sound design

  • Frequency and time-dependent parameters synchronize to a system tempo
  • Comprehensive selection of Inputs/Outputs
  • Front panel numerical key-pad
  • RS232 interface for connecting the DSP7000 to a computer
  • Two relays can be controlled from suitable programs, allowing the unit to drive real-world equipment and can switch up to 1.0A at 30V dc

So Fast and Easy to Use

Because each of these effects and hundreds more are already set-up and ready for instant recall, the DSP4000B+ is a terrific time saver in program and commercial production and post-production. And it's perfect for a fast-paced "Morning Zoo" radio show. Imagine trying to create a whole cast of character voices or "strange places" effects on-the-fly with an ordinary effects box! With the DSP4000B+, it's more than possible. It's easy. A six line graphic LCD screen lets you choose the effect you want in seconds...they're conveniently organized into logical groupings such as "Science Fiction Voices," "Commerce & Machines," and "Backgrounds." Every effect features a wide variety of user-adjustable parameters, and the LCD screen leads you quickly through the process, explaining how the various parameters affect the sound. In addition to saving presets you create in the DSP4000B+'s internal memory, you can also store them on a removable PCMCIA memory card for convenience and added capacity and to protect your unique sounds from use by others. 

Superb Quality Reverbs, Pitch Change, and Time Compression

In the production studio, you'll uncover more of the power of the DSP4000B+, because Eventide has also included the effects module software which makes the standard DSP7000 today's premier signal processor for recording and live performance.  Dense, lush reverbs, rich choruses, flanging and the best quality pitch change programs on the planet. What's more, the DSP4000B+ offers Timesqueeze® stereo time compression and expansion with higher quality than ever before. It's so easy to use...just punch in the current running time of the audio and how long you want it to be. 

Ready for the Digital Studio

The Eventide DSP4000B+ comes standard with analog and digital inputs and outputs. The digital I/O provides full 24-bit AES/EBU and S/PDIF for an all-digital signal path along with simultaneous XLR-type analog inputs and outputs. Optimal audio quality is assured via 24-bit A/D and D/A converters. Audio bandwidth at the analog connectors is up to 22kHz, with 44kHz (at 96K sampling) also available for most presets. Its remote control interfaces include MIDI In/Out/Thru jacks and a serial port. The serial port can also be used with the powerful VSIGfile program editor, or connected to a PC for available operating system upgrades over the internet.  (Want sampling to further extend the capabilities of the DSP4000B+?  Take a look at the DSP7500!)
Although we've emphasized the DSP4000B+'s many programmed production effects, there's a whole other side to the unit, which will be of special interest to advanced "effects explorers." Unlike conventional audio processing units which contain a limited number of fixed digital processing algorithms, the factory programs of the DSP4000B draw on over 200 internal effects modules to create a wider variety of truly distinct programs than ever before possible. What's more, the unit's object-oriented Algorithm Construction Kit patch editor function lets users (and third-party developers) build totally new effects algorithms by linking modular effects "building blocks" which are presented on the large, graphics LCD screen. With the DSP4000B+, there are always new effects avenues to explore, new sounds to create.

This is the unit that says "don't let the video and film guys have all the fun." There's a whole world of audio special effects waiting to be explored. The Eventide DSP4000B+ Broadcast/Production Ultra-Harmonizer is your first-class ticket to instant audio creativity.
