AKG combined the best of classic and present-day technologies, the legendary C 12 transducer capsule and advanced transformerless FET circuitry. Although it looks almost the same as the C 414 B-ULS, the TL II differs in two respects.
First, the transducer provides a similar sound as the popular C 12. Its frequency response above 4 kHz is the same as that of the classic C 12 with a slight high-frequency boost. Below 4 kHz, however, the C 414 B-TL II has an absolutely flat response. The second difference is that the C 414 B-TL II has a transformerless output stage for accurate reproduction down to the lowest frequencies.
This version of the C 414 is the preferred tool for miking up vocals and distant miking, e.g., of classical music. It provides the same preattenuation pads and bass cut filters as the C 414 B-ULS, and comes complete with a windscreen, spider type suspension, and individual frequency response printout.

The C 414 B-TL II/ST is a matched pair of C 414 B-TL IIs for stereo recording. The two microphones are carefully selected for identical frequency responses and sensitivities. Complete with individual frequency response printouts, accessories, H 50 stereo bar, and carrying case (Sound Tool Case, big size).
