Chapter 7 - Digital Connections
To Two or More ADATs
If using two or more ADATs, they must be connected together so that they are in sync with each other. This is accomplished by connecting each ADATÕs SYNC OUT connector to the SYNC IN connector of the next ADAT in the chain, as described in the ADAT Reference Manual.
The fiber optic cables that make up the digital buss need to be connected in the same order as the Sync cables. The Q20 is inserted in the fiber optic loop from the output of the second ADAT to the input of the master ADAT. The Q20 lets you turn its digital output into a ÒthroughputÓ of the digital input. This allows you to move audio through the Q20, even when you donÕt want to use it to process anything, without having to repatch your fiber optic cables. More information about digital audio routing can be found in the next section.
To connect the Q20 to two ADATs:
➀Connect an EIAJ fiber optic cable (available from your dealer) from the [DIGITAL OUT] of the Q20 to the [DIGITAL IN] of the first ADAT.
➁Connect another fiber optic cable from the first ADATÕs [DIGITAL OUT] to the second ADATÕs [DIGITAL IN].
➂Connect another fiber optic cable from the second ADATÕs [DIGITAL OUT] to the Q20Õs [DIGITAL IN].
➃Connect a dual male, 9 pin D cable from the first ADATÕs [SYNC OUT] to the second ADATÕs [SYNC IN].
