In 1973, the Colette series was launched, the most extensive and versatile microphone system ever conceived. The "Active Colette tubes" are familiar to the millions who have seen the Three Tenors or "Les Miz" on TV; they are also used by the upper house of the German Parliament. The "Active cable" is widely used (but not seen!) in "stashed" (hidden) microphone rigs by film and TV recordists, in stage sets, and in concert halls and opera houses. This is possible because the microphone amplifier can be separated from the capsule. making the visible part of the microphone substantially smaller. Today, this modular microphone system has been widely imitated, but SCHOEPS continues to offer the widest selection of transducers and accessories. That same year the MK 6 Colette capsule was developed out of the MK 26. A year later it was followed by the MK 5, a switchable two-pattern capsule (omni/cardioid) with improved high-frequency response. The MK 5 is still in the catalog.
All models have been improved over the years. Today the Colette-series includes 20 capsules, 6 micophone amplifiers (analog, digital, battery-powered, for pocket transmitters, tube version), active accessories (such as microphone tubes, filters, goosenecks, table microphones, cables) and accessories (like elastic suspensions, cable hanger, clamps, stands, instrument adapters, pop- and windscreens) as well as stereo microphones and accessories for stereo and surround.
