Battery-powered Microphone Amplifier
CMBI
- 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.
Please note:
Neither the Colette Series Active Accessories nor the BLM
03 Cg can be used with the CMBI. |
