Abstract: According to a first aspect of the embodiments, a microphone mixer is provided comprising: an input adapted to receive differential microphone (mic) output signals; a gain-trim circuit adapted to receive the differential mic output signals, and which includes a substantially fully differential amplifier adapted to amplify the received differential mic output signals through use of a gain-trim output adjustment device that provides a variable gain amount ranging from a first gain-trim gain value to a second gain-trim gain value, to produce differential gain-trim circuit output signals; a fader circuit adapted to receive the differential gain-trim circuit output signals, and which includes a differential amplifier adapted to attenuate the received differential gain-trim circuit output signals through use of a fader output adjustment device that provides a variable gain amount ranging from a first fader gain value to a second fader value; and a common adjustment apparatus that mechanically ties the gain-trim output adjustment device with the fader output adjustment device such that the first gain-trim gain value and first fader gain value are obtained substantially simultaneously at a first position of the common adjustment apparatus, and the second gain-trim gain value and second fader gain value are obtained substantially simultaneously at a second position of the common adjustment apparatus.
