Overview

The Radio Systems Digital Distribution System is comprised of two units:

* Model GEN-DDA/WC
* Model DDA/WC-4x4

The Radio Systems model GEN - DDA/WC is a professional quality digital sync. generator with an

integrated AES/EBU distribution amplifier and six Word Clock outputs.
The two fully independent AES/EBU input sections feature balanced inputs to four buffered balanced

outputs. A three digit LED display for each section reads out the sampling frequency. Two LED’s for

each section indicate PLL (unlock) and data (validity) errors.

The Radio Systems model DDA/WC 4x4 is a professional quality digital distribution amplifier with four

independent sections of four output AES/EBU distribution and six Word Clock outputs.
The AES/EBU input sections feature balanced inputs to four independent, buffered balanced outputs.

A three digit LED display for each section reads out the sampling frequency. Two LED’s for each

section indicate PLL (unlock) and data (validity) errors.
