Introduction
Congratulations on purchasing the Rack Gizmo audio loop and function switcher. The Rack Gizmo has been designed
to give you total control of your amplifier, effects devices, effects pedals or other electronic equipment from a single
MIDI footswitch.
The Rack Gizmo provides eight audio loops, eight function switches and a professional quality audio buffer, all in a
compact, single rack space design. Using the Rack Gizmo, you can control virtually any amplifier or effects unit – more
than with any other MIDI-based switching controller. A wide range of custom cables is available to connect the Rack
Gizmo to the vast majority of the amplifiers on the market, and we are continually developing new cables to support
additional amplifiers and equipment.
Because the audio loops contain no active circuitry, the Rack Gizmo can work with any effects device regardless of
signal level. Your Rack Gizmo has four mono loops and four stereo capable loops (unless yours was ordered with the 8
stereo loop option). The stereo capable loops can switch either mono unbalanced, stereo unbalanced or mono
balanced signals using ¼” TRS jacks.
Rack Gizmo Features
• Eight audio loops for effect switching (four grouped in series, four independent)
• Eight function switches for amplifier control (channels, reverb, effects loops, etc.)
• Stereo or balanced capability on the last four loops (or on all loops, depending on the model purchased)
• A high-quality audio buffer that can bypassed or patched elsewhere in the audio path
• Click Stopper™ technology that reduces the click noise associated with relay-based switchers
• Works with all MIDI footswitches
• Responds to Program Change and Continuous Controller messages
• Easy programmability via front panel buttons and LEDs
• Up to 256 programs can be saved in memory
• High-quality relays for optimal sonic performance, compatibility and reliability
• Supports both latching and momentary switching modes
• Electrically isolated jacks prevent ground loops and allow safe control of multiple amplifiers
• Provides phantom power to compatible MIDI devices when used with 7-pin MIDI cable
