Schoeps CMBI Battery Powered Microphone Amplifier


Component Microphone Amplifier

What we think:

All capsules are available in matched pairs with official Schoeps documentation. For matched pairs multiply the cost of the microphone exactly by two and then add $40 dollars for the matching fee! The amplifier bodies are available in sequentially serial numbered pairs at no additional charge. Any Schoeps product not found on our webpage can be purchased through Sound Pure. Please call and talk to one of our staff members to inquire about the price and availability!

Manufacturer Description:

  • Unbalanced, medium-impedance output
  • For use with short cables (a few meters)
  • For connection to any desired microphone input

If a recorder has no phantom powering or a microphone input is unbalanced as in many portable recorders and wireless microphone transmitters, a phantom-powered microphone can be awkward to use. For these and other situations SCHOEPS offers the CMBI, a battery-powered microphone amplifier with unbalanced output.

Combine this with one of 19 microphone capsules of the Colette Series and you obtain a microphone which is acoustically equivalent to the balanced version using a CMC microphone amplifier. The CMBI features a readily available internal 6 V silver oxide battery which, combined with power-saving circuitry, gives up to 80 hours of operation. About 6 hours before the end of battery life a built-in LED begins to light up as a warning. In addition to battery operation, the CMBI allows for external powering through a standard XLR microphone cable. (The included K 5 ISK cable is not suitable for this mode of operation.) Because of this model's unbalanced, low-level output and its medium output impedance, the total cable length should be kept to less than about 15 m to avoid possible RF interference and impaired performance. Possible arrangements for connecting the CMBI are shown in the technical appendix.

Accessories included: wooden case, battery, adapter cable K 5 ISK (miniature plug to 3.6 mm mini stereo phone plug, 5 m long)

Available separately: microphone capsules, windscreens, etc.
