The C 480 B is part of a system designed specifically for excellent audio quality and maximum flexibility.
Its 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. Two sets of switches offer a two-step highpass filter, and two gain manipulation stages of either –10 dB or +6 dB.
