The AudioFuse X8 IN is a half-rackspace unit with 8 balanced line-level inputs on 1/4" TRS, each with a world-class analog-to-digital (A/D) converter. Output 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 provide data to any audio interface with ADAT inputs. Each input can have a switchable 12 dB Pad for loud input signals, and pairs of adjacent odd and even inputs can be Linked for easy stereo operation.
In addition to these features, the AudioFuse X8 IN can send clock signals over the ADAT outputs or receive Word Clock signals via a rear-panel BNC input with switchable termination. This lets you synchronize your audio interface to the AudioFuse X8 IN directly, or integrate it with a larger digital audio system using a common Word Clock.
The AudioFuse X8 IN 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 IN as a tabletop unit, and can be removed and put into use when attaching it to a second AudioFuse X8 IN or an AudioFuse X8 OUT 8-channel ADAT-to-line digital-to-analog (D/A) 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 IN is the easiest way to add more inputs to your audio interface rig – so you can always add that new synthesizer you've had your eye on! (And then another, and another...!)

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 IN, 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 IN 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.
Word clock is a clock signal used to synchronize devices together and can be used as an alternative to ADAT Sync depending on the devices, setup and needs.
In fact, Word Clock can be used to synchronize as many digital devices in your studio as devices can be easily chained together.
AudioFuse X8 IN provides a standard BNC connector for Word Clock data coming from an external clock source.
- In the example below, two AudioFuse X8 IN units have been connected from their ADAT 1 OUT ports (In 44.1 or 48Khz) to an AudioFuse 16Rig ADAT INs 1 & 2 with the help of ADAT (Toslink optical) cables to retrieve all their 8 channels.
- A BNC cable has to be connected from the AudioFuse 16Rig Word Clock Output to the First AudioFuse X8 IN Word clock Input and from there connected to the second Word Clock Input with the help of a “T” BNC connector to chain them together (Doing so will require a “T” along with two BNC cables).
Here’s an example of “T” connector used for such kind of purpose:
Of course, in such kind of setup, the main interface (here AudioFuse 16Rig) will have to be set to Internal clock source and the other interfaces (here AudioFuse X8 INs) set to External Word clock source with the help of the SYNC button located on the front panel:
Note
-Make sure to always and only use 75 Ohm BNC cables and "T" Connector.
-Also, on X8 side, please note that if no BNC cable is connected to the rear panel WORD CLOCK input, the SYNC button doesn't do anything – the unit defaults to Internal sync and can't be changed.
