CMR

Microphone amplifier for pocket transmitters

Properties

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.


Order number

  • No. 132009

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.
