5.7. Connecting to ADAT Digital Audio Devices

The AudioFuse 16Rig can support up to 16 channels of ADAT digital I/O by using the four
optical Toslink connectors on its rear panel. Each port carries eight channels of audio in one
direction when working at 44.1 or 48k sampling rates. Digitally connected devices can be
synchronized through the ADAT connection itself or via the nearby Word Clock BNC ports.

Note: This section describes how to connect devices using only ADAT cables (i.e., audio and digital
sync signals are both transmitted together through the optical cable). For larger, more advanced studios
with lots of digital equipment, Word Clock synchronization may be required or preferred. This is covered
in the next section.
In the illustration above, we have an AudioFuse 16Rig (top) connected to an AudioFuse 8 Pre
(bottom). ADAT optical cables carry digital audio to/from each unit. Synchronization signals
are also carried along the cable.
When working with digitally connected audio devices, it's vital that there is only one clock
source. Having all devices synchronized to one primary clock prevents clicks, pops, and
other audio artifacts that can arise from slightly mismatched clocks.
In this setup, the AudioFuse 16Rig acts as the primary reference clock and so its "Clock
Source'' parameter is set to "Internal." As a result, AudioFuse 8Pre must have its own clock
( the "Sync" parameter on its front panel) set to "ADAT'' so that it receives and synchronizes
itself to clock information coming from the AudioFuse 16Rig.
To do this:
1. Connect your digital audio devices to each other using the rear panel ADAT ports. The
output(s) of the AudioFuse 8Pre connect to the input(s) of the AudioFuse 16Rig and vice
versa.

Note: Each device has two input ports and two output ports. In this example, the second port is only
necessary if you are working at higher sampling rates (88.2 or 96k). Since we are working at standard
(44.1 or 48k) sampling rates, only the first input and output ports are used.
2. Ensure that the clock source of AudioFuse 16 Rig is set to "Internal" while the clock source
of AudioFuse 8Pre (labeled "Sync" on the front panel) is set to "ADAT".

Note: If AudioFuse 16 Rig is connected to a computer, the Clock Source and Sample Rate parameters
in the hardware may be grayed out. If so, you need to change the Clock Source and/or Sample Rate
parameters from the AFCC or your DAW.
