This unit is extremely easy to use, with a large custom LCD display and dedicated rotary controls for the four most critical reverb parameters. Its 20-bit AD/DA oversampling converters and independent left and right channels ensure superb sonic performance, and a dual level control and two four-segment LED level meters simplify level setting for optimal performance.

Snare and rim shot samples are built in, so programs and edits can be auditioned directly from the front panel (AUDITION button), while balanced XLR and phone jack connections allow simple hookup to professional or semiprofessional gear. Input and output levels for each channel are independently  switchable between -10dB and 4dB.

REV500 supports real-time parameter control via MIDI Control Changes and program selection via MIDI Program Changes. MIDI Bulk Dump is used for user program backup. Reverb programs are categorized into groups for selection ease. The 100 preset programs and 100 user programs are divided into four categories: Hall, Room, Plate and Special.
