For Sale: Classic Rack-Mount Stereo Effects Unit

This is an excellent opportunity to own a legendary piece of digital audio processing gear. The Alesis Midiverb II is a compact, professional-grade effects processor that has become a studio and live performance staple since the late 1980s.

What You're Getting

• fully serviced and working perfectly (serial number: 054552)
• original power supply unit (230V German plug)

A fully functional 16-bit linear PCM digital effects processor housed in a single-rack-unit (1U) format. This unit combines professional-quality sound processing with user-friendly operation, making it perfect whether you're running a high-end studio setup or managing live sound at a venue.

Sound Quality & Effects

The Midiverb II delivers 99 powerful preset effects including:

• Lush, characterful reverbs perfect for adding depth and space
• Classic gated reverb sounds that defined the 80s and 90s
• Chorus, flange, delay, and pitch-shifting capabilities
• The iconic "Bloom" effect—a unique signature sound many engineers love
• Up to three simultaneous multi-effects for creative layering

The 16-bit processor with 15-16 kHz bandwidth produces warm, professional-grade audio with minimal noise and distortion. This unit is celebrated for capturing the sonic character of that era while delivering genuine musicality across any source material.

Technical Specifications

Connectivity & Control:

• Two stereo analog inputs and outputs (1/4" jacks)
• MIDI input and output for remote preset selection and control
• Instant recall of presets via front panel or MIDI commands
• High impedance inputs accommodate everything from instrument-level signals to professional +4dBu console outputs

Audio Performance:

• 16-bit linear PCM processing
• Wide dynamic range for nuanced detail
• 15-16 kHz frequency response
• Minimal harmonic distortion for crystal-clear digital processing

Why This Unit Stands Out

The Midiverb II is valued for several reasons: its affordability compared to high-end alternatives, its reliability and durability, the quality of its presets (which cover an impressively wide sonic palette), and its straightforward operation. Musicians consistently praise it for delivering professional results without requiring extensive tweaking. The built-in MIDI control makes it incredibly versatile for modern studio and touring setups.

Perfect for producers, sound designers, guitarists, keyboardists, and anyone seeking authentic vintage digital effects in a compact, dependable package.

FYI:

• I have included a photo of the entire rack, because a single rack unit is difficult to photograph because of it's extreme width.
• It's not me playing on the YouTube video. Just some video I found on YT showing the unit.
