Analogue Inputs
The Analogue Inputs page controls the input amplifiers and microphone
biases. Each of the GAIN panels sets the target gain for the amplifiers, and
the GAIN STATUS shows the currently active gain setting. Each of the CTRL
panels sets the enable, mute, and gain change behavior (ramped or zero-
crossed) for the amplifiers. The MIC CTRL panels allow selection of single-
ended or differential input signal. The MICBIAS CTRL panel enables and sets
the output level for the microphone bias outputs. The MIC CONFIG panel sets
the clock and data format when digital microphones are used.
