beyerdynamic MC 930 Stereo Set B-Stock - Matched Pair of Small-Diaphragm Condenser Microphones with Accessories

Capturing pristine stereo recordings demands microphones with exceptional clarity, low self-noise, and precise matching. The beyerdynamic MC 930 Stereo Set B-Stock delivers a matched pair of small-diaphragm true condenser microphones, ideal for studio vocals, acoustic instruments, choirs, and ambient sound. Each MC 930 features a cardioid polar pattern and a wide frequency response from 40 Hz to 20 kHz, ensuring transparent and detailed audio reproduction. The pressure gradient transducer and high sensitivity of 30 mV/Pa make these microphones suitable for even quiet sources, while the ability to handle up to 124 dB SPL accommodates loud instruments without distortion. This B-stock set includes two microphones, clamps, windshields, a stereo bar, and a hard case, providing everything needed for professional stereo recording.

Who is it for

This stereo set is perfect for recording engineers, producers, and musicians who need a reliable matched pair for overhead drum miking, piano, string ensembles, or acoustic guitar. It suits both project studios and professional facilities, offering high-end performance at a reduced price due to B-stock condition (fully functional, may have minor cosmetic blemishes).

Tips

Use the included stereo bar to mount the microphones in XY or ORTF configurations for accurate stereo imaging. For best results, engage the 48V phantom power on your preamp or interface. The low self-noise makes the MC 930 ideal for capturing quiet sources like fingerpicked guitar or room ambience. Always store the microphones in the hard case to protect the capsules.
