1–2 • Introduction ADA-8402-A User Manual (Iss. 01)
Overview
The ADA-8402-A is an AES/EBU distribution amplifier designed for broadcast use. It provides
eight copies of the incoming unbalanced AES-3id signal when used with the R2A-8402 Full Rear
Module or four copies of the incoming signal when used with the R2SA-8402 Split Rear Module.
The ADA-8402-A supports audio sampling frequencies from 32kHz to 96kHz. Cable
equalization and reclocking techniques enable the ADA-8402-A to recover the incoming digital
audio signal reliably.
The ADA-8402-A also includes built-in loudness measurement. The card is capable of reading
the ITU1770 LKFS Audio Measurements and displaying the measurement in DashBoard.
The R2SA-8402 high density split rear module can accommodate up to two ADA-8402-A cards,
each configured as a 1x4 DA, accommodating up to 20 channels of distribution per 2RU frame.
