Product overview

The SCHOEPS CMC 1 K is the version of the small Colette microphone amplifier CMC 1 with a permanently attached cable: identical to the CMC 1 U, but with a fixed cable in place of the built-in XLR connector.

It is a complete alternative to the renowned CMC 6 and fully compatible with all existing MK capsules and with Colette active accessories such as the CUT 60 low-cut filter and the RC tubes. The housing is only 29 mm long and weighs about 28 g without the cable.

The CMC 1 K is available with different cable lengths and plugs: the standard version has a 5 m cable with an XLR-3M connector, and two 0.5 m versions with a 3-pin Lemo plug connect to pocket transmitters with P12 or P48 powering. Special versions with any cable length are also available. Like every CMC 1, it reaches 135 dB-SPL with the MK 4, draws only 2 mA at 48 V and carries the SCHOEPS RFI Shield.
