Schoeps BLM 03 C

Schoeps BLM 03 C [131501]

The Schoeps BLM 03 C is a miniature boundary layer microphone capsule for the modular Colette system. Its fixed 5 m cable connects to a separate CMC microphone amplifier. Together, these components form a complete microphone.

Measuring 80 mm in diameter and 8.6 mm in height, the BLM 03 C can be placed unobtrusively on a conference table, on an altar or inside a grand piano. The capsule picks up sound from the half-space above its mounting surface.

Main Features

• Compact boundary layer microphone capsule with a hemispherical pickup pattern.
• Fixed 5 m cable for connection to a Colette CMC microphone amplifier.
• Suitable for speech, grand piano and room recording.
• Low-profile housing with a matte gray Nextel finish.

Placement

Place the BLM 03 C on a sufficiently large, sound-reflecting surface. A table may be sufficient for a panel discussion; Schoeps recommends a larger surface for most music recordings. Inside a grand piano, it can be used with the lid open or closed.
