Condenser Microphones

Description

The AKG C 480 B preamplifier powering unit is the latest
model in the ULS series. It accommodates the CK 61/ULS,
CK 62/ULS, CK 63/ULS capsules and the new CK 69/ULS
shotgun capsule, providing a higher order of performance for
these capsules than heretofore available. The new preamp
has a vastly improved noise floor, permitting self noise
performance with the four associated capsules in the range
of 9 to 11 dB-A. Maximum sound pressure levels in the range
of 144 dB (in the -10 dB sensitivity position) can be attained
with no greater than 0.5% distortion, giving the capsules a
new level of overall performance. An integral low cut filter
(12 dB/octave) can be set for either 150 or 70 Hz. The +6 dB
sensitivity position is intended to enhance the performance of
the CK 69/ULS interference tube capsules, which normally
operate over large distances. With the available CK 61/ULS
cardioid, CK 63/ULS hypercardioid, CK 62/ULS
omnidirectional, and highly directional CK 69/ULS shotgun
element, the C 480 Series is intended primarily for studio,
broadcast and a variety of live sound and speech
reinforcement applications in which state-of-the-art
performance is mandated. A complete line of optional
accessories is available. The C 480 B operates only on 48
volts phantom powering.
