ensures generous headroom
The C 542 BL 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 C 562 BL, the C 542 BL is small, light-
weight 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 C 542 BL 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.
Easy to use and sonically versatile, the C 542 BL is a great
addition to the "mic locker'' of any studio.
