Ultra Linear Series 

                         The C 480 B system combines unparalleled performance with
                         exceptional flexibility. Patented electronic circuitry coupled to a
                         transformerless output stage assures completely linear
                         transfer characteristics across the entire audio bandwidth,
                         while achieving self-noise figures close to the theoretical
                         minimum. This, in combination with a typical SPL handling
                         capability of 140 dB broadband means a dynamic range
                         exceeding 125 dB, making the system suitable for the most
                         critical digital recording applications. Gold plated switch and
                         connector contacts guarantee consistent performance. A
                         specially designed output stage drives difficult loads (e.g.
                         excessively long cables) with no signal degradation. The C 480
                         B pre-amp offers additional sensitivity due to a new 48 volt only
                         format. Two sets of switches offer the following features: Two
                         step high pass filter, and two gain manipulation stages of
                         either ­10 dB or +6 dB.

                         Each of the "ULS" series capsules must surpass the strictest
                         tolerances for accurate presentation of both on and off-axis
                         source material. A three micron, gold sputtered diaphragm
                         utilizes AKG's uni-tension, double-stretched mylar for superb
                         transient and frequency response unaltered by temperature
                         and humidity shifts.
