Abstract
A monolithic integrable mixer network for a mixer console includes a variable gain preamplifier for each sound channel, a summing amplifier whose summing gain is adjustable differently for each sound channel, and a control unit which divides the channel gain for the respective sound channel between the preamplifier and the summing amplifier according to a ratio dependent on the desired channel gain to optimize the noise performance of the mixer network.
