SCHOEPS
CMBI BATTERY-POWERED MICROPHONE AMPLIFIER
CMBIg
- with unbalanced, medium-impedance output
- for use with short cables (a few meters)
- designed for connection to any desired microphone input
The CMBI uses a readily available 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 the connection cable. As is normal with unbalanced, low-output-level devices having moderate output impedance, the connecting cable should not be longer than about 15 m, in order to avoid possible RF interference and impaired performance. Please note: neither the Colette Series active accessories nor the BLM 03 C can be used with the CMBI.
Instead of a large XLR connector, the CMBI has a flush-mounted 5-pin miniature connector at its output. For normal connection of the CMBI to a DAT recorder, etc., a 5 m cable with a 3.5 mm mini stereo plug is included. This cable can be extended with a standard 3.5 mm stereo jack-to-stereo plug cable, or with a miniature-plug extension cable such as a Schoeps KS 5 I. For operation with pocket transmitters we have ready-made cables with special connectors on request.
For stereo recordings there is a Y-shaped cable (KIY 250/0 I) which connects two CMBIs to a compact junction box via two pieces of cable, each 250 mm in length. The short cable leading out of this box has a miniature plug and can be extended with the standard KS ISK cable. Other cable lengths are available on request.
Included: case, battery, adapter cable K 5 ISK.
Separately available: microphone capsules, windscreens, etc.
