The ultra-high quality analogue 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.
32-bit Processing Plus 20-bit Conversion for Superior Sound
Development of 3rd-generation DSP (Digital Signal Processing) LSI is behind some extraordinary sonic &functional; enhancements in the Yamaha ProR3 Digital Reverberator. 32-bit DSP power coupled with high-performance 20-bit linear A/D and D/A converters delivers unprecedented density, superior resolution and astonishing dynamic impact. Analog input and output circuitry has also been built to the highest possible standards, contributing to a very impressive dynamic range of 110dB.
Complete Reverb System with EQ, Gate, Compression and Dynamic Filter
In addition to one of the finest digital reverb processors available, the PROR3 includes all other processing stages you need to fine tune the reverb sound.
Digital Pre-and Post-reverb EQ
These stages offer extensive response-shaping control. 3-band sweepable pre-verb EQ controls are available on the front panel for fast, easy access. Post-reverb EQ stage is parameter-programmable and offers even greater control versatility. Three bands with independent frequency, gain and Q(bandwidth) parameters are provided. Frequency coverage is much broader than pre-reverb EQ. For even greater flexibility the low and high bands can be independently switched for shelving or peaking response.
Programmable Noise Gate
The Yamaha ProR3 noise gate provides much more than simple threshold control. In addition to a threshold level adjustable from -60 to 0 dB, the gate features a trigger delay programmable from 0.1 to 100 milliseconds, hold time from 1 to 5759 milliseconds and release time from 6 to 24000 milliseconds. Level detection can be carried out at the gate itself or at the pre-reverb signal. The gate can also be triggered via MIDI, if required.
Full Function Compressor
The Yamaha ProR3 processing chain includes a precision compressor with threshold, output level, ratio, knee (soft, normal or hard), attack time, and release time parameters. Precisely controllable compression can help you to achieve an exceptionally clean, refined reverb and effects sound with unprecedented presence and spaciousness.
Dynamic Filter
Dynamic filtration can add extraordinary variety to the reverb and effect sound, from subtle sonic nuances to dynamic sweeps. This dynamic filter is extremely versatile, providing low-pass, high-pass and band-pass modes with programmable centre frequency, resonance, sensitivity, decay and shift direction.
Top-Quality Reverb-Based Effects
The Yamaha ProR3 has been designed primarily to do one job extremely well…providing absolutely natural reverberation. Its effects are therefore all based on reverberation, although a few combinations of reverb and modulation type effects are provided for an extra margin of versatility. All PROR3 programs are based on one of 11 basic effect types.
90 Presets and 90 User Memory Locations
The PROR3 is supplied with 90 presets which can be used without modification in a wide range of applications. The presets can also be edited to “fine-tune” them for a specific sound, or completely re-programmed to create totally new effects. Edited effects can be stored in any of 90 user memory locations for instant recall when needed.
Broad I/O Compatibility
The Yamaha ProR3 is equipped with both XLR-type connectors and 1/4″ phone jacks for compatibility with all types of equipment. Both connector types are electronically balanced, but the phone jacks can be used directly with mono signals as required. -10dB/+4dB level selectors on both the inputs and outputs provide an extra margin of level-matching flexibility.
MIDI Interface for Extra Control Capability
The MIDI interface-complete with IN, THRU and OUT connector-allows it to be easily integrated into MIDI-based systems. A programmable patch table makes it possible to use MIDI program change numbers to select any of the effect programs, while MIDI control change data can be assigned to control up to 2 different effect parameters in real time. The MIDI interface also features program dump capability, user effect data can be saved to a MIDI data recorder or sequencer and re-loaded as required.
Large LCD
Large 24-character x 2-line backlit LCD displays multiple related parameters at once for easy programming and operation.
Direct Access Keys
Allow for fast access to specific parameter groups for efficient programming.
Editing
Compare function allows instant A/B comparison between the original and edited sound while editing.
Reverb Parameters
The basic Yamaha ProR3 reverb program – with an extraordinary range of parameters. 2-stage reverb processing achieves extremely smooth, natural reverb and allows true stereo reverb if required. A programmable dynamic filter adds significantly to the vast sonic potential of this and all other “Yamaha ProR3 effects. True stereo reverb processing is also available.
Early Reflections Parameters
In addition to 6 preset early reflection types, 4 “user” types can be created (i.e. individual reflection levels and pan positions can be specified as required) for the ultimate in customise early reflection precision.
Room Simulator Parameters
Although basically a reverb program, the Room Simulator is configured to allow control via a range of parameters which correspond directly to the dimensions and characteristics of a simulated room.
Echo + Reverb Parameters
This program combines echo with reverb — one of the most commonly used combinations in recording and sound reinforcement applications. Three “patches” are provided: series echo to reverb, series reverb to echo and parallel echo with reverb.
Early Reflections + Reverb Parameters
This combination of early reflections and reverb is capable of producing some exceptionally natural-sounding ambience effects. Like the Echo + Reverb program, three “patches” are provided: series early reflections to reverb, series reverb to early reflections and parallel early reflections with reverb.
Chorus + Reverb; Symphonic + Reverb; Flange + Reverb Parameters
These three programs combine the Yamaha ProR3’s outstanding reverb sound with chorus, symphonic and flange type modulation respectively, making it easy to add a subtle touch of animation to the reverb sound or produce wild “jet reverb” effects. In all cases three patches are provided: two serial and one parallel.
Pitch Change + Reverb Parameters
Pitch change capability can be extremely useful for creating artificial harmonies or adding a subtle extra touch of high or low end to the basic sound. The pitch change portion of this program allows two pitch variations to be created in addition to the original sound. The series patches allow the reverb sound to be pitch-changed, while the parallel patch allows the original sound to be pitch-changed independently from the reverb effect.
Pan+ Reverb Parameters
Auto-panning and reverb form a useful combination for many applications. This program provides the same three patches – two serial and one parallel – as most of the other combination programs, so that panning can be applied to the reverb or direct sound as required.
