This is a vintage 1978 Sennheiser VSM 201 Vocoder. With regard to design, sound quality and historical context, the VSM 201 is considered by many to represent the absolute pinnacle of vocoder effects. With production believed to be under 100 units total, combined with an original price of $20,000.00 US, claiming the Sennheiser VSM 201 was reserved for a highly specific clientele would be a serious understatement: there are simply none available.
First and foremost, this particular example (serial number 32) was recently professionally serviced, and is currently in absolutely perfect working condition. The capacitors, resistors and chips that were removed during the maintenance are all intact and included, so the unit remains 100% original. The original wood transportation case and original rubber feet are also included.
Famously used by Herbie Hancock, Kraftwerk and iconic silver screen robots, the VSM 201 is the ultimate vocal effect. Having inspired modern digital representations and miscellaneous plug-in programs, this original VSM 201 is superior in every respect.
A superficial inspection will reveal an impressive; 55 knobs, 69 LEDs, 11 switches and 34 sockets. Technically, this legendary unit features; 20 separate channels with fixed envelope routing internally from each analyzer envelope generator to the corresponding VCA, numerous mic and line inputs with a corresponding VU meter. As the complexity of the control panel implies, there is much much more to describe.
