The Reslo Ribbon Microphone
Thanks to Mr. Ellis Dawson for his kindness in providing these Installation Instructions from 1961.
The Mayfair-based Reslo company in the city of Westminster, UK produced many versions of the RB ribbon microphone in the 1960s. A VBT broadcast version also was made. The transformer mounted in the cylindrical stem provides matching and Low (white plug dot), Mid (green or blue plug dot), and High (red, yellow, or orange plug dot) impedance variants. Some also have switchable impedances. The ribbon is positioned to the rear of the mic and the shells can be removed to allow various acoustic ﬁlter pads to be ﬁtted. These modify both frequency and polar response to a degree. Twin mounts and stereo pairs have been made.
