AKG C451B/ST

AKG C451B/ST

Matched pair of C 451 B

The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 200 Hz to 15,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.

The kit includes all the standard accessories of the individual package along with a stereo bar and proof of performance charts in an attractive carrying case (Soundtool case, middle size).

Features:

Identical acoustics to legendary CK 1

Precise, nearly frequency independent cardioid

Extremely accurate signal transfer and ruler-flat on-axis frequency response

Also available as a matched stereo pair
