YAMAHA REV100

The REV100 is a no-fuss signal processor — just select one of its 99 top-quality preset effects and you're ready to go. When you do need something specially tailored to the occasion, the REV100 makes editing easy. The three most critical parameters for all effect programs are adjustable via rotary panel controls. Just rotate the appropriate controls until the sound is right. With reverb programs, for example, the panel controls give you direct access to the initial delay, reverb time, and high-frequency damping parameters. Input level and dry/wet balance controls are also provided. And when you create a sound you want to keep, just press the STORE button to register it in the REV100 memory. Of course, you can recall the original Yamaha presets whenever you like. Each of the parameter controls also has an LED that lights when the control setting matches the preset parameter value. The presets include reverb, delay, and modulation effects, plus a range of combinations so if you need reverb and flanging, for example, it's right at your fingertips.

Reverb
Programs 1 ~ 20: This category includes the essential reverb effects such as realistic hall, room, and plate reverb simulations. 
Stereo Reverb
Programs 21 ~ 40: True stereo reverb effects that let you add ambiance to stereo signals without sacrificing the stereo image. 
Gate Reverb
Programs 41 ~ 50: A range of "gated" reverb effects that add warmth and ambiance while maintaining a tight sound. 
Delay
Programs 51 ~ 60: A selection of mono and stereo delay programs including straightforward one-shot repeats and complex bounce effects. 
Delay/Reverb
Programs 61 ~ 70: Combinations of delay and reverb that can add a little more life to your sound than delay or reverb alone. 
Reverb/Modulation
Programs 71 ~ 99: Reverb combined with a range of modulation effects including flange, symphonic, chorus, and tremolo.

With common mono-in/stereo-out processors you can't directly add reverb to a stereo signal. You could use two processor units, or mix the signal to mono and sacrifice the stereo image. The REV100 actually has stereo inputs and outputs, and a range of true stereo reverb programs that offer realistic ambience without destroying your stereo image. The REV100 will also function in the standard mono-in/stereo-out mode if you don't need stereo processing.

The quality of your effect sound is just as important as the original sound itself. The REV100 offers CD-quality sound with 16-bit A/D and D/A converters and a 44.1 kHz sampling rate. The result is full 20 Hz to 20 kHz frequency response with exceptionally low noise and distortion, so your effects are totally clean and natural.

If you'll be using the REV100 in a MIDI music system, it offers some features that can make operation extra convenient. You can select effect programs via MIDI rather than the panel controls. This can be handy when you want to automatically select different effects for different patches on a synthesizer, for example. You can also use MIDI control change commands to actually change effect parameters, so you can vary the effect sound in real time while playing.

Compact "1U" rack-mount dimensions. 
Easy-to-read 2-digit LED display. 
Peak LEDs make it easy to set the optimum input level.
