To the AI-1

If you wish to route the digital output to a device that uses AES/EBU or S/PDIF
standards, you can connect the QuadraVerb 2 to the Alesis AI-1. This can be done
directly, by connecting the QuadraVerb 2's [DIGITAL OUT] to the AI-1's DIGITAL IN
and the QuadraVerb 2's [DIGITAL IN] connected to the AI-1's DIGITAL OUT.
Alternatively, if you are using multiple ADATs and the BRC (as described above), you
can simply insert the AI-1 into the fiber optic chain, either before or after the
QuadraVerb 2.
In the BRC/ADAT system illustration above, the AI-1 is inserted between the last
ADAT in the chain and the QuadraVerb 2. In this scenario, you can route the
QuadraVerb 2's digital output to any ADAT in the chain, or the AI-1 (for routing to
another digital audio peripheral using either AES/EBU or S/PDIF standards). You can
also route audio to the digital inputs of the QuadraVerb 2 coming from any ADAT in
the chain or the AI-1 (for processing digital audio from some other digital audio
peripheral). More information about digital audio routing can be found in the next
section.

From the QuadraSynth

The Alesis QuadraSynth and S4 sound module both have Alesis Optical digital
outputs. These devices provide their four analog audio outputs on the first four
channels of the 8 channel digital buss. Simply connect a single fiber optic cable
between the QuadraSynth's DIGITAL OUT connector and the QuadraVerb 2's
[DIGITAL IN] connector. If the ADATs are being controlled by a BRC or AI-2, the
QuadraSynth's clock must be controlled by the 48 kHz OUT of the BRC or AI-2.
Connect a BNC cable from the BRC or AI-2 to the QuadraSynth's 48 kHz IN jack.
