Schoeps BLM 03 C Boundary Layer Capsule, Matte Gray

SKU CH-4Y54-CEX05

A boundary-layer capsule with hemispherical pickup, 20 Hz–20 kHz range, 12 dB-A self-noise, 82 dB-A signal-to-noise, 128 dB max SPL and two low-cut filters

  • Pristine audio capture across a 20Hz-20kHz frequency range
  • Remarkable purity with a low 12 dB-A equivalent noise level
  • Polished recordings backed by an 82 dB-A signal-to-noise ratio
  • Distortion-free handling of loud sources up to 128 dB maximum SPL
  • Comprehensive coverage from a hemispherical polar pattern

Boundary Layer Capsule for Colette Series

The Schoeps BLM 03 C is a boundary layer microphone capsule designed for professional audio capture in television, film and critical recording work. Its hemispherical polar pattern picks up sound from all directions while the matte gray finish keeps the unit discreet on surfaces such as vehicle interiors or piano lids. An active hard-wired cable connects directly to any Colette series amplifier except battery-operated models.

Suited for Surface Mounting and Low-Noise Capture

Engineers who need an unobtrusive capsule with a 20 Hz to 20 kHz range and 12 dB-A self-noise will appreciate the clean signal and 82 dB-A signal-to-noise ratio. The 128 dB maximum SPL handles loud sources without distortion, and two low-cut filters suppress low-frequency rumble. Users who require a wireless solution, a different polar pattern or a battery-powered amplifier should look elsewhere.

Colette Amplifier Compatibility Required

This capsule operates only when paired with a mains-powered Colette series microphone amplifier; the hard-wired cable does not terminate in a standard connector. Verify that your amplifier is part of the Colette range and is not a battery-operated model before purchasing.

Questions about this item

Does the BLM 03 C include a microphone amplifier or must I supply a Colette series preamp separately?

The capsule has an active hard-wired cable and requires any Colette series microphone amplifier except battery-operated models, which must be purchased separately.

How do the two low-cut filters change the 20 Hz low-end response?

The two low-cut filters provide precise adjustment of low frequencies and highly effective suppression of low-frequency rumble below the 20 Hz range.

What does the 12 dB-A self-noise mean for quiet studio recording?

With an equivalent noise level of 12 dB-A and an 82 dB-A signal-to-noise ratio, the capsule captures very quiet sources with minimal added hiss.
