(12) Mic Input
Connect the supplied microphone for the Auto-EQ feature to this mini-jack.
(13) IR Input
This is a connection that allows the utilization of a third party infrared remote sensor, such as Elan or
Xantech, or an extended cable for placement closer to your other remote controlled equipment. This
keeps you from awkward control angles using the infrared remote control.

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

This XLR input jack receives the balanced LFE signal from your receiver or processor.
