1.5 Brief Description

The C 542 BL is a boundary microphone. The trans-
ducer element is flush mounted in a thin disk. If you
mount the microphone on an acoustically reflective
boundary (wall, floor, ceiling), the sound entry will be
positioned almost in the same plane as the acousti-
cally reflective surface and will point toward the sound
source. This method prevents comb filter effects and
other interference that would normally cause problems
in microphones placed near reflective surfaces.
The sensitivity and frequency response of the micro-
phone depends on the disk position. The larger the
boundary, the smoother the resulting frequency re-
