MEB 102 (-L), MEB 104 (-L) Install Boundary Layer Microphone

FEATURES

• Unobtrusive, timeless design
• Optimized for speech
• Made in Germany Compact and unobtrusively designed, the boundary layer microphones MEB 102 (omnidirectional) and MEB 104 (car- dioid) fits any style of interior and can be easily installed into surfaces such as tables or ceiling tiles. Each of them features aproven Sennheiser microphone capsule for the best speech intelligibility, and is protected by a rugged housin. Its -L variant features a bi-color LED ring for status indication. DELIVERY INCLUDES

The omni-directional micropho- ne capsule shall be optimized for speech intelligibility. The microphone capsule shall be protected by a rugged sound inlet basket. The frequency response shall be 40 Hz-20,000 Hz and sensitivity shall be 16 mV/Pa. Nomi- nal impedance at 1 kHz shall be 200 Ω. Equivalent noise le- vel shall be 21 dB(A) or 31 dB weighted as per CCIR 468-3. Dynamic range shall be 104 dB(A). Maximum SPL shall be 125 dB. The microphone shall provide an XLR-3 connector and an M20 thread. The microphone shall operate on 48 V phantom power. Current consumption shall be 3 mA. Dimensions shall be 28.5 mm (1.12“) in diameter and 83 mm (3.27“) in total height. The installation height shall be 12 mm (0.57“). Weight shall be 58 grams (2.05 oz). Operating temperature shall range from 0 °C to +40 °C (+32 °F to +104 °F). The micro-phone shall be the Sennhei- ser MEB 102. The Sennheiser MEB 102 microphone shall also be available as a variant (-L) with an XLR-5 connector and a bi-color LED ring for status indication. The current consumption of the -L version shall be 6 mA. The TLL voltage for LED activation shall be high level > 2.4 and low level < 0.4 V. The microphone shall be a pre-polarized condenser boundary layer microphone designed for fixed installati- on in conference applications. The cardioid microphone capsule shall be optimized for speech intelligibility. The microphone capsule shall be protected by a rugged sound inlet basket. The frequency response shall be 40 Hz-20,000 Hz and sensitivity shall be 14 mV/Pa. Nomi- nal impedance at 1 kHz shall be 200 Ω. Equivalent noise level shall be 28 dB(A) or 38 dB weighted as per CCIR 468-3. Dynamic range shall be 97 dB(A). Maximum SPL shall be 125 dB. The micro-phone shall provide an XLR-3 connector and an M20 thread. The microphone shall operate on 48 V phantom power. Current consump- tion shall be 3 mA. Dimensions shall be 28.5 mm(1.12“) in diameter and 90 mm (3.54“) in total height. The installation height shall be 19 mm (0.75“). Weight shall be 60 grams (2.15 oz). Operating temperature shall range from 0 °C to +40 °C (+32 °F to +104 °F). The microphone shall be the Sennheiser MEB 104. The Sennheiser MEB 104 microphone shall also be availa- ble as a variant (-L) with an XLR-5 connector and a bi-color LED ring for status indication. The current consump-tion of the -L version shall be 6 mA. The TLL voltage for LED activation shall be high level > 2.4 V and low level < 0.4 V.
