"Vintage new old stock for an SF805 Modulation Source module from the Studiomaster Studiofex system. Studiomaster described the Studiofex as "a fully modular studio effects system which brings together both the features and the performance which today's music demands". The module is 4U high and utilizes +/- 15 volts DC. It comes in the original foam padded box, it has the original manual with full installation and operating instructions, mounting scrws and decal for rear panel as well as a pinout diagram for the connector socket."

A description I found on the Internet claims:
'The SF805 Modulation Source is capable of producing not only regular, cyclic voltages with all the smoothness of a sinewave, bit also other waveshapes, trigged single sweeps, single controlled modulation depth and even signal envelope following modulation. Two outputs are provided, each with an independent DEPTH control so that two devices can be modulated simultaneously.'

"This is the SF805 Modulation Source module from the Studiomaster Studiofex system. Studiomaster described the Studiofex as "a fully modular studio effects system which brings together both the features and the performance which today's music demands". The module is 4U high and as far as I can tell utilizes +/- 15 volts DC though it may work with other voltages. It comes in the original foam padded box, it has the original manual with full installation and operating instructions and there is also a hand drawn wiring diagram that may be of use for integrating into your system. I bought this unit to put in a modular system I was building but it never came to fruition, so I have no explicit knowledge of the module in question. Thus it is sold as-is, no returns.

More info on the Studiofex system, including manuals can be found here:
