Yamaha ProR3 Digital Reverberator

Yamaha ProR3

The Yamaha ProR3 marks a new era in Yamaha’s reverberation technology. Third-generation Yamaha digital signal processors (DSP) with 32 bit digital signal processing and high-performance 20 bit linear A/D and D/A converters provide unprecedented density and resolution, with breathtakingly dynamic impact.

The ultra-high quality analog input and output circuitry achieves a dynamic range of 110 dB, providing incredibly natural reverberance with a noiseless decay.

The Yamaha ProR3 has 10 primary effects; reverb, early reflection, room simulation, and combinations of reverb with echo, chorus, flanging, pitch change, and auto pan, etc.

A pre-effect EQ is provided in front of the primary effect, and following the primary effect, dynamic filter, compressor, EQ, gate, level, and balance stages are provided. In stereo input mode, full stereo reverb is provided. In addition to 90 preset programs for immediate use, 90 user memory locations are provided for your own custom settings.

The stereo inputs and outputs of the Yamaha ProR3 feature both balanced XLR type and 1/4″ phone jack connectors, for connection to a variety of equipment.

The input and output level selectors (–10 dB/+4 dB) also allow flexibility in level adjustment. Programs can be selected from an external MIDI device, and bulk data dumps can also be performed.

The Yamaha ProR3 digital reverberator is the result of an important step forward in digital reverberation technology. It provides a previously unattainable level of rich reverberation effects, sound quality, and operability, and is an ideal reverberator for use in any situation, from the home studio to pro audio recording and PA work.

Yamaha have definitely moved on a generation in reverb technology, and the introduction of a 20-bit system at this price is also welcome...The subjective reverb quality is the all-important factor, and though far better than anything I've previously heard from Yamaha...I have no hesitation in recommending it as a powerful processing tool.
