AES Input
HomerLink is a data bus format designed by Symetrix which allows
4monobidirectionalAES-3digitalaudiochannelstobetransmitted
between devices up to 100 meters apart over standard CAT-5 cable.
HomerLink outputs (Pins 1, 2, 4 and 5) are exact copies of the AES
OUTXLRjacksontherearofthe6200.Thecontentofthesepins

AES audio or clock input.
The HomerLink sync cable is the only manner in which the 6200 can
receive an AES digital input or sync to an external AES digital clock.
The pinout provided below can be used to design a custom breakout
boxwithstandardXLRconnectors.
Enabling AES Input
These steps walk you through setting channel 1’s input source to AES.
1. Press the HOME button to ensure that we are starting from the top.
2. Press the NEXT button once.
3. Thedisplayshouldread“SectiontoEdit,-Channel1Menu-”.
4. Press the NEXT button three times and the display should read “Input
Signal Source, ANALOG”.
6. Turn the ADJUST knob clockwise until the menu reads “Input Signal
Source, DIGITAL”.
NOTE: The above steps assume you are setting Channel 1’s input
source. The steps are similar for Channel 2.

any questions regarding the integration of the 6200 into your network,
consult your friendly IT/IS personnel or your network hardware’s
documentation.
