NOTE: Although digital information is coming out of both XLR and RCA jacks simultaneously, the correct format will only appear at the output for the format type selected. For example, if you have AES/EBU format selected, an AES/EBU formatted signal will appear at the output of both the XLR and the RCA connector. Or, if you have S/PDIF format select- ed, an S/PDIF formatted signal will appear at the output of both the RCA and XLR connectors.

Sync In and Out Connectors

BNC connectors are provided for both word clock in and out functions. The 376’s clock chips are dbx custom VCXO chips, designed for low-jitter performance. You may use the 376 as a master clock source, having other equipment slave to the 376, or you may slave the 376’s clock to any other word clock source.

3.3 Sync Input Sample Rate Selection

When connecting an incoming or master device to the sync input of the 376, the 376 will auto- matically lock to the sample rate of the master device. The sample rate will then be indicated in the SAMPLE RATE select button.

Note that when the master device is disconnected from the Sync Input connection, the SAMPLE RATE select button will flash until an internal sample rate is selected.
