Mixer/Preamplifier Model 207t

A six-input mixer and preamplifier after the Buchla 207, with left and right signal outputs and a monitor output. Each input A to F has a blue switch sending it to the signal outputs through its slider, and a yellow switch sending it to the monitor. Assignment knobs pan inputs B to E between left and right; A and F are panned by control voltage, two lamps under each showing where the signal goes. Expansion inputs link two mixers into a twelve-in, two-out mixer. The preamplifier takes a 6.35 mm TRS microphone or line input, its gain set by a knob and a 55/70 dB switch. Part of the Buchla & Tiptop Audio 200t series, made under licence from Buchla.
