Hookups

Once the AES-8 units are installed you are ready for the fiber-optic connection. Attach

       the fiber-optic cable to each of the AES-8 units at the FIBER connector. The optical
       transmitter and receiver require 62.5/125m multimode fiber-optic cable with ST

terminations. For field applications, secure it first by loosely tying off to the rack or a

       nearby anchor point. Special singlemode units require 8/125 micron cable with ST
       connectors.

If you are using multi-core fiber-optic cable with your system, the individual fiber lines

       will be color coor-dinated or numbered to help you identify each separate fiber line.
       Now connect all the AES digital audio inputs and outputs. An example of these

hookups are demonstrated above in figure 4, Digital Audio Hook-up Diagram.

Operation

Before power-up, configure the AES-8 units for use. At the Tx unit, the SAMPLE RATE

       switch should be set to EXT. for external sync. The AES-8 will then detect and

synchronize to the first valid AES input signal of the eight AES Digital inputs. For the

       Rx unit, the SAMPLE RATE switch can be set to the known sample rate frequency or a
       sync signal can be brought in at the SYNC IN and the SAMPLE RATE switch set to
       EXT. This is the typical configuration when using the AES-8 to transmit AES Digital
       Audio signals as demonstrated in the diagram above. The system can now be powered
       starting with the appliances preceding the AES-8, then the Tx and Rx units, and finally
       the equipment following. The units should immediately process signal unless

 configured or hooked-up improperly.

The Adder AES-8 Transmission System was designed to mount in a standard 19" rack.

       When mounting inside an enclosed rack make sure there is adequate ventilation.  You
       should avoid placement next to excessive heat sources such as power amplifiers or
       heaters. In portable installations where subject to severe mechanical shock, secure the
       rear of the units.
