1973 - The Famous Colette Series
manufactured until today - see www.schoeps.de

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 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 MKT 26. A year later it was followed by the MK 5, a switchable two-pattern capsule (omni/cardioid) with improved high-frequency response. Both are still in the catalog.

1974, the Colette series was made available on an OEM basis to Studer. They renamed the CMC microphone amplifiers SKM (for Studer Kondensator Mikrofone).

1975 the lavalier microphone CM 03 is added to the Colette series. It is particularly thin and flat in profile, yet its technical specifications match the quality of large studio condenser microphones. It was manufactured in many different adaptions.

Model Overview of the Lavalier Microphone:

CM 03 C lavalier microphone with a Colette connector for direct use with a CMC amplifier
CM 03 S lavalier microphone for Sennheiser transmitters SK1007 and SK1007-1
CM 03 L lavalier microphone which ended with a miniature Lemo plug. Different adapters were available to use it with different equipment:
ALC adapter to connect the CM 03 L to a CMC amplifier
ALB adapter to connect the CM 03 L to a Beyer transmitter TS73 or TS83
ALS adapter to connect the CM 03 L to a Sennheiser SK1007 or SK1007-1
ALN adapter to connect the CM 03 L to a Nagra SNN portable tape deck
CM 03 S8 lavalier microphone with connector for Sennheiser transmitter SK1008
CM 03 S10 lavalier microphone with connector for Sennheiser transmitter SK1010
CM 03 B lavalier microphone for Beyer transmitter TS73 or TS83
CM 03 M lavalier microphone for Mikron transmitter TX101 or TX 102

1976 the MCQ 3 / MCQ 4 / MCQ 5 four channel Colette mixer was devellopped. Powered by one single microphone input (12V phantom power for the MCQ 3, 12V T-power for the MCQ 4, 48V phantom power for the MCQ 5) one could connect up to four Active cables and mix these four channels to one output.

1976 Schoeps launched the MSTC 54 "ORTF Stereo" microphone, embodying one of the most effective simple stereo techniques ever devised. It is still in general use, and is especially popular in its country of origin, France. Since 1992 it is delivered as MSTC 64 for universal supply 12-48V.

1978 the CM 02, a special version of the CM 03 with flat on-axis high frequency response, is offered as an instrument microphone. Special mounting adapters for specific instruments are available for its use. In the same year the figure eight MK 8 was added to the capsule family.

1979 the Active filter CUT 1 (picture right above) is added to the COLETTE series. It prevents infrasonic disturbances with a 24 dB/octave filter below 70 Hz, with 6 dB/octave of that low-frequency rolloff being variable in frequency to compensate for proximity effect or room acoustics. It is still manufactured. You find it described here. In 1999 the CUT 2 followed with a corner frequency of 30 Hz instead of 70 Hz

1981 The MK 2S is introduced and the MK 2 got a higher linearity. Also the swivel GVC was published.

1983 the boundary-layer plate BLM 3 came on the market, and soon won in a comparison test with similar units. Two years later, in 1985, it was produced in miniaturized form as the Active boundary-layer capsule BLM03C.

1985 the CMC5 with MK40 capsule was published as an OEM product CM 90 for Strässer

1987 the wide cardioid MK 21 followed.

1990 the RC-KC and TR 200 KC (right picture) completed the Active Acessory series

1992 the new CMC 6 allowed a phantom power of 12V or 48V with automatic switch of the supply current. A special version with extended frequency range up to 40kHz followed in 2003: CMC 6-U xt

1994 the side fired cardioid MK 4V followed.

1995 the CMBI battery powered amplifier came into market.

1998 LC 60 / LC 120 inline low cut filters with 60 or 120 Hz corner frequency, balanced, phantom powered

2002 LP 40 inline low pass filter with 40 Hz corner frequency allowed to extend the MK41's frequency range down to 20 Hz by means of an omni capsule adapted via this LP 40

All models have been improved over the years. You find the current Colette series described in detail at www.schoeps.de

Power Supply Overview:

CMC 3- 12V phantom power
CMC 3p 12V phantom power with reverse polarity (i.e. with the plus pole grounded)
CMC 4- 12V parallel feed (T-power)
CMC 4k 12V parallel feed (T-power) with reverse polarity for Nagra Kudelski consoles
CMC 5- 48V phantom power
CMC 6- 12V or 48V phantom power with automatic supply detection

All models could show further indices like "D" (for Tuchel connectors), "U" (for XLR connectors), "F" for the French Sogie connector, "R" for encreased common mode rejection ratio or "n" (for fixed 10dB attenuation). They could also be marked with a colored dot, blue for a +5dB amplification, white for compensation of proximiy effect, red for high frequency emphasis.

Connector Overview:

CMC -U XLR-3 connector with pin1 = GND, pin2 = + signal, pin 3 = - signal
CMC -D Tuchel-3 connector with pin1 = + signal, pin2 = GND, pin3 = - signal
CMC -F Sogie-7 connector (French market only) with pin H = + signal, pin D = - signal, pin C = B = GND
CMC -L Lemo-3 connector plus a constant current diode for P24 .. P48 powering (Austrian market only)
