The AudioFuse X8 OUT is a half-rackspace unit with 8 balanced line-level outputs on 1/4" TRS, each with a world-class digital-to-analog (D/A) converter. Input is provided on a pair of Toslink optical ports using the ADAT digital audio standard, which run at 24-bit resolution and can operate at sample rates up to 96 kHz. These will accept audio data from any audio interface with ADAT outputs.
In addition to these features, the AudioFuse X8 OUT can use clock signals over the ADAT connectors or via a BNC Word Clock input with switchable termination. This lets you synchronize the AudioFuse X8 OUT to your interface with no added cables, or integrate it with a larger digital audio system using a common Word Clock.
The AudioFuse X8 OUT comes in a convenient half-rackspace chassis, complete with one rack ear and one connector plate. These stay out of the way when using the AudioFuse X8 OUT as a tabletop unit, and can be removed and put into use when attaching it to a second AudioFuse X8 OUT or an AudioFuse X8 IN 8-channel line-to-ADAT analog-to-digital (A/D) converter unit. The result is a conventional single-rackspace processor that can be added to any standard rackmount system.
Simple to set up and seamless to use, the AudioFuse X8 OUT is the easiest way to add more outputs to your audio interface setup – so you can set up multiple check monitors, or enjoy surround mixes with multiple output speakers!

Once you've set up your hardware, the next part of the process is to register it with Arturia.
Follow the instructions you'll find in the box with your unit to log onto the Arturia website, and register it. You will need a serial number and unlock code, which you will find on the bottom of the unit.
You can also go directly to the AudioFuse X8's Start page, and follow the instructions there.
After registering your AudioFuse X8 OUT, you'll be able to download the different software effects from our creative suite and Analog Lab Intro.
The bottom of the unit has a pair of recessed storage positions, one for a single orange rack ear and one for a square connecting plate. Each has two mounting screws of the appropriate size.
Note
Note that the connecting plate has four screw holes but only two screws. The extra holes are used to connect to a second unit using its supplied screws.
Note
The unit comes with mounting screws especially chosen for this purpose. Don't use other screws, and carefully follow the directions in this FAQ article. You don't want your new converter to fall out of your rack, do you?
Attach the rack ears and connection plates in the configuration shown above, and the AudioFuse X8 OUT and its companion X8 OUT or X8 IN are ready to slot into your rack.
Note
We recommend rackmounting the AudioFuse X8 units with an open rackspace above or below them, to assist with keeping them cool during operation.
SMUX (Sample Multiplexing, often written S/MUX) is a subset of the ADAT optical audio specification that allows for an ADAT connection to carry data at higher sample rates by sacrificing channel count.
An ADAT connection can carry 8 channels of 24-bit data at either 44.1 kHz or 48 kHz. Using SMUX, that same connection can carry 4 channels of data at up to 96 kHz, or 2 channels of data at up to 192 kHz.
Note
The highest sample rate provided by the AudioFuse X8 OUT (or the X8 IN) is 96 kHz. If it's fed a sample rate higher than that, the ADAT LED will blink to indicate that the clock isn't usable.
The two ADAT inputs on the AudioFuse X8 OUT allow for 8 channels of conventional ADAT over one port or 8 channels of ADAT SMUX over two ports. When using SMUX, channels 1–4 are available at the first port and channels 5–8 are available at the second port, as indicated on the rear panel labels.
Either the ADAT or ADAT SMUX LED will light, depending upon the type of sync signal received. It will automatically be recognized by the AudioFuse X8 OUT.
Some third-party digital devices don't send the proper information to set SMUX automatically when connected.
In that case, the AudioFuse X8 OUT lets you force it to recognize SMUX clocking by long-pressing the SYNC button.
In Force SMUX mode, both the ADAT and ADAT SMUX LEDs will be lit.
Note
Short-press the SYNC button to get out of Force SMUX mode.
