For customers who wish to feed a professional equipment using AES/EBU inputs and long cables with the Vanity103HD module, there is a modification available that increases the output drive, matches the output impedance to 110R and adds a GND signal to form a true balanced AES/EBU connection.
You can find the modification instructions in the following link, but doing the modification yourself voids the warranty.
The modification service can be also ordered from JVB with full warranty.
Please note there is an external adapter or custom cable needed and you have to make it yourself.
Should you have any questions, please ask in this thread.
Regards,
Pavel
