Battery-powered Microphone Amplifier
CMBI
バッテリー電源マイクアンプ
- 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(spec.) 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:
