AKG Acoustics Microphone ULS SERIES User Manual

ULS Series  
Condenser Microphones  
Description  
Features  
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  
• Ultralow noise preamplifier for use  
with ULS series capsules  
• Multiple directional capsules and  
configurations available on a high  
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  
performance powering/preamp  
module  
• Extremely flat on-axis response for  
all models  
• Three sensitivity settings  
(0, +6, and -10 dB)  
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  
• High acoustic level capability  
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.
