Gemini BPM-1 Automatic DJ BPM Counter & Table Top Rack

Description

Gemini BPM-1 Automatic DJ BPM Counter & Table Top Rack
Designed with deejays in mind, but with applications for live and studio use (setting delay times, etc.) the Gemini Automatic BPM counter, the BPM-1, is a one-rack-space unit that uses new proprietary circuitry to count the tempo of almost any song. It features four stereo inputs, convertible from line inputs to phono inputs, which let you loop in any four sources, including turntables, CD players, MiniDisc players, MP3 players or cassette decks.
The front panel is simple: dual buttons and digital displays, LED source indicators and a bargraph LED Beat Offset Indicator array. The literature enclosed with the BPM-1 claims that it can track and display music up to 180 beats per minute.
Upon powering up, the BPM-1 performed a self-test routine that sets the units timers to sync and prepares it to count the beats. The two buttons on the front panel assign the appropriate input channel to the correct side of the display and set the beat counting process in motion. Once the inputs are set, unless you need to change them, no further button pressing is necessary.
I'm including a table top studio rack (like the one pictured above) with the BPM counter.
