The AKG C451 B is a small-diaphragm condenser microphone known for its accurate sound reproduction and robust build. It is the modern successor to the legendary C451 EB, featuring an identical acoustic performance to its predecessor. Its transformerless preamp ensures high output, low noise, and excellent transient response. The C451 B is highly versatile, perfect for recording acoustic guitars, drums (overheads, hi-hats), pianos, string instruments, and as a vocal spot mic. It includes a switchable pre-attenuation pad (0 dB, -10 dB, -20 dB) and a switchable high-pass filter (75 Hz, 150 Hz) to adapt to various recording situations and prevent overloading at high SPLs.
