Overview

The 9253 is a Dual AES/EBU distribution amplifier designed for broadcast use.  It can provide
four copies of each incoming signal. It may also be used to provide up to eight outputs that
are sample rate converted.

The 9253 supports audio sampling frequencies from 30kHz to 192 kHz.  Cable equalization
and reclocking techniques enable the 9253 to recover the incoming digital audio signal
reliably.

The 9253 is housed in the HPF-9000 or similar 20-slot frames.
