Overview

Plug-in module converts the XLR inputs and outputs to AES3, providing 2x in on two XLR-Fs and 2x out on two XLR-Ms.

Rate Conversion

Sample Rate Converters on all inputs and outputs. Inputs can accept 32, 44.1, and 48kHz rates. Clock for outputs may be sourced from the AES inputs or internally-generated, locked to the ISDN network.

Input Level

Adjustable from -27 to -12 dBfs

Output Level

Adjustable from -27 to -12 dBfs
