Cardioid polar pattern for multiplicity of vocal and instrument applications
The earlier model C 3000 has had a large fan club in the project studio and home recording worlds for years. For the new C 3000 B, AKG designed 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.
