Audio interface
Two different microphone inputs and two different speaker outputs are
supported.
The WISMO Quik Q24x6 Series also includes an echo cancellation feature
which allows handsfree function.
2.12.1 Microphone inputs
The MIC2 inputs already include the biasing for an electret microphone
allowing an easy connection to a handset.
The MIC1 inputs do not include an internal bias. MIC1/SPK1 is then
appropriate for a hands free system or a handset with biasing external to the
module.
