Ken Zelin, International Training Manager at McIntosh Labs introduces their new patented quad balancing technology to achieve greater dynamic range in their high end amplifiers. The dynamic range is defined as the difference between how quietly and how loudly a system can play. Larger amplifiers tend to produce more signal ënoise’ due to the higher number of transistors. McIntosh have solved this problem by ëflipping’ the noise signal and combining it with the original, thereby eliminating it. The result is an astonishing signal to noise ratio of 129Db. Finally we get to see the technology inside a 2 channel controller with Ruthenium contacts similar to those used in nuclear reactors.
