AKG C 542BL OMNIDIRECTIONAL-HEMISPHERICAL CONDENSER BOUNDARY MIC

C 542 BL 
 
Extremely small and inconspicuous, lightweight yet rugged
Delivers superior sound combined with outstanding ease of use
High sensitivity and low self-noise 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 frequencyindependent.
Succeeding the proven C 562 BL, the C 542 BL 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 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.
