Multivox MX-312 Multi Echo Effects Unit

Tape echo is a type of delay. Producers and engineers created delay and echo effects using tape machines. A signal would be routed to a separate tape recorder from the one being used to record the performance that was set to monitor off its repro head where the resulting effect creates an echo.

Multivox was an American-based synthesizer company from the mid-1970s until the 1980s.
