Individual three-band parametric EQ parameters are provided for each effect program for precise tonal tailoring. In addition to the basic effect and EQ parameters, the Yamaha Rev5 offers a list of “internal parameters” which provide exacting control over the effect sound. The REVERB programs, for example, feature a total of 12 parameters that make it possible to create precisely the required effect. The Yamaha Rev5 is also MIDI compatible, with a MIDI IN terminal that allows MIDI selection of effect programs, and a switchable MIDI THRU/OUT terminal. When switched to OUT, edited programs stored in internal RAM can be dumped to a MIDI data recorder or other data storage device. Programs thus stored can be reloaded when necessary via the MIDI IN terminal. As an extra touch of convenience the Yamaha Rev5’s electronically balanced input and output terminals can be switched to match -20 dBm or + 4 dBm line levels – providing compatibility with a broader range of sound equipment.
