Sound Semiconductor New Mixer Chip Provides Voltage Control of Six Inputs into a Single Output

Sound Semiconductor announced the ProCircuit 6-into-1 Voltage Controlled Mixer. Based on a new-generation Operational Transconductance Amplifier (OTA), the patent pending SSI2190 allows current-mode linear control of each channel. Differential voltage inputs provide design flexibility, and a high-compliance current output makes summing from multiple sources - including other SSI2190’s - an easy endeavor.

A Look Inside Douglas Self’s "Small Signal Audio Design" 4th edition

Whether it is power amplifiers, vinyl reproduction preamplifiers, active crossover filters or, as in this case, small-signal circuits for a very wide range of applications, Douglas Self is one of those authors who consistently has produced reference works about technical audio. You may think that as a fourth edition, it would just be a refinement on the three editions that went before it but Self always adds new material and new insights to make it worthwhile to get this new book.

No Zipper, No Pop! How ADC Hybrid Gain Control Can Enable Smooth, Pop-Free Microphone Preamp Gain Changes

This article explains the new hybrid gain control (HGC) feature of Cirrus Logic’s latest CS530xP family of Pro Audio ADCs and how these can eliminate noise problems when changing gain on digitally controlled mic preamps. This solution enables fine-resolution mic preamp gain control, with the feel of a traditional potentiometer but without audible pops or zipper noise by integrating control into the ADC, together with zero-cross detection and precisely synchronized digital gain control.
