(12) Mic Input
Connect the supplied microphone for the Auto-EQ feature to this mini-jack.

This is a connection that allows the utilization of a third party infrared remote sensor, such as Elan or

keeps you from awkward control angles using the infrared remote control.

the use of the serial port, available commands, and their formats.
