The AKG Acoustics C 3000 B, has a special 1-inch large-diaphragm transducer that closely approximates the vibration performance of top-class studio microphones, but can be made at much lower cost. Due to its surface area and special capsule tuning, the C 3000 B large-diaphragm transducer produces an exceptionally pleasing, smooth sound.

Unlike in the C 3000, the switchable 10-dB preattenuation pad immediately follows the transducer in the signal path, thus increasing the C 3000 B's SPL capability by a true 10 dB. Loud sound sources are therefore no problem. An acoustically optimized cardioid polar pattern makes the C 3000 B an excellent choice for both recording and live sound applications where high gain before feedback is paramount.
