Avalon VT-747sp Module

Some products are hard to find teardown images, and Avalon is one of them.
I recently found these images of the VT-747sp and noticed this small module mounted on a small pcb called "Avalon AD2101".

It is used on all stages, inputs and outputs, eq and compressor.
Is that a small buffer?
Did anyone already know? Have you tested?

I appreciate any information.
