AKG Acoustics C 542 BL manual Specifications

•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 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.
