AKG C451B Small-Diaphragm Condenser Microphone Studio

The AKG C451 B is a modern continuation of one of professional audio's most respected microphone lineages. Originally introduced as the C451 EB with the CK1 capsule in 1969, the design became a studio standard for its detailed, transparent sound on acoustic instruments. The current C451 B retains that signature airy character while incorporating modern manufacturing techniques, including surface mount electronics and a transformerless output stage that together reduce weight, lower self-noise, and improve reliability. The result is a microphone that captures every nuance of a sound source with minimal coloration — exactly what engineers need for critical recording applications.

What sets the C451 B apart in practical use is its combination of fine detail and sheer headroom. With a maximum SPL handling of 155dB, it can be positioned inches from a snare drum, a cranked guitar cabinet, or a brass section without any risk of overloading the capsule or preamp. The switchable 12dB/octave high-pass filter provides effective control over low-frequency rumble, making it equally useful on a vibration-prone stage as in a treated studio. The cardioid polar pattern provides focused pickup with good off-axis rejection, and the balanced XLR output ensures clean signal transfer over long cable runs. Housed in a robust nickel-finished metal body, the C451 B is built to deliver consistent performance over years of studio sessions and live dates.
