Microphone Input & Audio Mixing
The MFP62 features a microphone input that can support 48V phantom power, balanced and unbalanced microphones, as well
as line level audio input. It also features auto audio ducking where by the input source’s audio decreases in volume and the
microphone audio is mixed over the top. This feature is enabled by default and can be customised via the MFP62’s web GUI or RS-
232. The illustration below outlines how the microphone audio mixes over the input source’s audio.

When using the microphone mixing functionality, it is recommended to only use 2ch audio sources, or set the EDID of the product
to a 2ch EDID. While the MFP62 does support multichannel audio, mixing the microphone input over the multichannel signal is not
possible hence the source audio drops out when the microphone audio is triggered. To enable multichannel audio support, you
must choose a multichannel EDID via the Web GUI of the product.
