Schoeps BLM 03 C Miniature Boundary Layer Capsule
An Active Cable hard-wired to the BLM 03 Cg allows it to be joined to any microphone amplifier of the Colette series (except the battery-operated model CMBI) to become a complete microphone. The BLM 03 Cg offers all the recognized advantages of the BLM 3g.
It is recommended in those cases where the BLM 3g is too large (e.g. for TV or film sound) or too heavy, e.g. for mounting in the interior of a car under the roof, or beneath the lid of a piano.
The CUT 1 and CUT 2 active low-cut filters can be used with the BLM 03 Cg.
- pressure transducer with hemispherical pattern
- active miniature version of the BLM 3g
- unobtrusive, universally applicable
- preferred applications: on speaker's podiums, altars, ambient sound recording or for recording orchestras
- diameter: only 80 mm

The small dimensions of the BLM 03 CG and its matte gray surface allow for a particular unobtrusive placement. It can often be disguised or hidden, e.g. under a light tablecloth.
Any boundary-layer microphone must be placed on a sound-reflecting surface large enough for adequate low frequency pickup. A table top may suffice for speech applications such as conference recording, but most setups for music recording will require a larger surface.
The BLM 03 C can also be placed in a grand piano, with the lid either open or closed
