Monolithically integrable mixer network for a mixer console
First Claim
Patent Images
1. A monolithic integrable mixer network for a mixer console controlling different channels, comprising:
- a variable gain preamplifier for each channel;
a summing amplifier, coupled to the output of each variable gain amplifier, having a summing gain adjustable differently for each sound channel; and
,an electronic control unit, coupled to each variable gain preamplifier and the summing amplifier, serving to automatically control an overall gain for each sound channel gain being divided between its variable gain preamplifier and the summing amplifier according to a predetermined ratio dependent on the desired channel gain, the ratio varying in the attenuation range with increasing channel attenuation such that the summing gain is reduced more than the preamplification by the variable gain preamplifier.

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.
