AKG CBL99
Boundary Mic, Lightweight

OUR PART #  CBL99


The CBL 99 is a high-quality boundary microphone designed to deliver superior results for a multitude of recording applications. The boundary layer technique is well-known for recording and offers non-directional pickup that is frequency independent.

Succeeding the proven CBL 99, the CBL 99 is small, lightweight and easy to place. No stand is needed. Since the transducer sits in a metal plate only 5 mm (0.2 in) thick, the plate doesn’t interfere with or color the sound. Frequency response is very uniform within its hemisphere and it captures the “room sound’’ of an instrument very accurately.

The CBL 99 can be permanently attached to the floor or wall of a studio using the screw holes in the plate or attached temporarily using the supplied adhesive compound. Its 3-pin output connector also has a switchable bass-cut filter to minimize surface-born noise.

  • Polar pattern omnidirectional (hemispherical)
  • Frequency range 20 Hz to 20 kHz
  • Sensitivity 20 mV/Pa (-34 dBV)
  • Max. SPL 130 dB (for 1% THD)
  • Equivalent noise level (IEC 60268-4) 16 dB
  • Signal/noise ratio (A-weighted) 78 dB
  • Bass filter switchable flat or 150 Hz, 12 dB/octave
  • Impedance <600 ohms
  • Recommended load impedance >=2.000 ohms
  • Supply voltage 9 to 52 V phantom power to IEC 61938
  • Powering <2 mA
  • Connector 3-pin XLR
  • Finish matte black
  • Net weight 56 g (2 oz.) (without cable)
