Optimizing Dynamic Range of Balanced Audio Inputs
EE Times, September 22, 2008 — By Bob Moses, THAT Corporation
Balanced interfaces are ubiquitous in professional audio systems due to their ability to reject common-mode hum and noise. They are especially important in long-distance connections where each end has a different ground reference. Maximizing common-mode rejection (CMR) is often a primary concern of designers. This article explores another important consideration–maximizing dynamic range.
