AKG Acoustics C414 B-TL II
Multi-Pattern Condenser Microphone
The C 414 B-TL II is a transformerless multipattern FET condenser microphone — essentially, a transformerless version of the long-lived C414 B-ULS. It is a descendant of AKG’s classic C 414 microphone, and the first of the “gold grille” series that resulted in the B-XL II and XL II.
The B-TL and B-TL II marked the end of the transformer-coupled C414 microphone, the last of which was the B-ULS. The TL II further introduced a revised CK-12 capsule intended to recreate the sonics of the vintage AKG C12 microphone.
The new capsule retained the nylon tension ring and snap-to-fit construction techniques developed for the C414 EB, but the capsule was revoiced with a boosted high-frequency response:
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.
From this point onward, the C414 models with gold grilles used the brighter, revoiced CK-12 capsule, whereas the silver grille mics used the flatter-response version of the capsule. AKG markets the gold-grille mics for vocals and distant-miking applications, and the silver-grille (flat-response) mics for applications in which “linearity” or “neutrality” are more desirable.
Pattern selection on this mic is accomplished via an electronic pushbutton below the mic’s headbasket. Four patterns are provided: Omni, Cardioid, Hypercardioid, Figure-8.
Two additional pushbuttons on the rear of the mic body provide access to a preattenuation pad (0dB, -10dB, -20dB) and a high-pass filter (flat, -12dB/octave @ 75Hz or 150Hz).
The mic was also available in stereo pairs (AKG p/n C 414 B-TL II/ST) — the kit included two mics selected for matching sensitivity and frequency response, a stereo bar (p/n H 50), two mic clips, two shockmounts, two foam windscreens, and a large Soundtool flightcase.
The AKG Acoustics C414 B-TL II is also known as: C414 B-TL II.
The mic was released in 1993.
