AKG 451EB with CK-1 Capsule.
AKG’s C-451 “Condenser Modular Series” (CMS) microphones remains a popular studio microphone despite having been discontinued since 1994. The C-451 preamp body accepted a variety of detachable capsules, extension tubes, and pads, making it a versatile performer.
The “C-451 E” had an XLR output. The “C-451 C” had a DIN connector. Either way, the mic was AKG’s first FET condenser.
A subsequent design, the “C-451 EB,” had a switchable high-pass filter, providing a 14dB/octave cut at either 75Hz or 150Hz.
