Schoeps CMR Colette Microphone Amplifier
SKU: #CMR
Features
• Amplifier for pocket transmitters without phantom power
• ATTENTION: there are a limited number of compatible transmitters, including Sennheiser, Wisycom and others, see Downloads. Use with digital transmitters is not intended, as interference may occur.
$529.00
The CMR is an amplifier for use in direct combination with MK capsules and pocket transmitters.
It is designed to draw only approx. 2-4% of the power required by the CMC 6. No 48V phantom power is necessary; instead only a supply voltage/current of 4V/1mA is required, as is generally provided by most pocket transmitters for driving electret capsules.

Practice
The CMR allows an MK capsule to be used with pocket transmitters. As with electret microphones, only a very low supply current is required, yet the CMR offers low output impedance and good immunity to interference.
The biggest benefit of all, however, is SCHOEPS’ well-known sound quality, which this amplifier delivers fully.
The robust connecting cable is reinforced with Kevlar fibers. It remains flexible at low temperatures, and does not twist.
The CMR can be used with devices which provide 1 mA for a microphone at 4 Volts or higher. The current list of compatible devices can be viewed at the compatibility chart in the downloads below.

Schoeps KC 10 Active Colette Cable (10m)
Features
• cable for insertion between the capsule and the amplifier of the Colette system
• contains active electronics for impedance conversion of the capsule
• 3 mm thin, robust, tear-resistant cable
• a special sheath makes the cable torsion-proof, meaning that the hanging cable does not lose its orientation even when the ambient temperature rises.
• Signal transmission to the microphone amplifier is conducted asymmetrically, so the length should be less than 20mSKU: KC 10
