The ADA-8402-B is an AES / EBU distribution amplifier designed for broadcast use. It provides 8 copies of the incoming balanced AES3 signal when used with the -R2B full rear module or 4 copies of the incoming signal when used with the -R2BS 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 internal audio processing for independent channel gain, sum (mono), left or right channel only, and ITU1770 LKFS loudness measurements, which are displayed in DashBoard.

The -R2BS high density split rear module can accommodate up to 2x ADA-8402-B cards, each configured as a 1×4 DA, accommodating up to 20 channels of distribution per 2RU frame.
