2 Audio
The input and output audio signals have different stages and each stage is programmed to vary the gain response characteristics. For microphones, both single-ended inputs and differential inputs are supported. To maintain a high quality signal, a stable bias voltage source to the condenser microphone’s FET is provided. The DC blocking capacitors are used at both positive and negative sides of the input. Internally, this analog signal is converted to 16-bit, 8/16 kHz linear PCM data.
