ADA-8402-B User Manual (Iss. 04)
Overview
The ADA-8402-B is an AES/EBU distribution amplifier designed for broadcast use. It provides
eight copies of the incoming balanced AES3 signal when used with the 8310AR-042 or
8320AR-042 Full Rear Modules or four copies of the incoming signal when used with the
8320AR-043 Split Rear Module. The ADA-8402-B supports audio sampling frequencies from
32kHz to 96kHz. Cable equalization and reclocking techniques enable the ADA-8402-B to
recover the incoming digital audio signal reliably.
The ADA-8402-B also includes built-in loudness measurement. The card is capable of reading
the ITU1770 LKFS Audio Measurements and displaying the measurement in DashBoard.
The 8320AR-043 high density split rear module can accommodate up to 2x ADA-8402-B cards,
each configured as a 1x4 DA, accommodating up to 20 channels of distribution per 2RU frame.
Features
The following features make the ADA-8402-B the best solution for distributing digital audio
signals:
• Operates as a:
›
1x8 AES distribution amplifier (8310AR-042 or 8320AR-042 full rear modules) or
›
1x4 (high density) AES distribution amplifier (8320AR-043 split rear module)
