1. INTRODUCTION
Thank you for purchasing our compact audio interface, the MiniFuse 2. We at Arturia are
committed to delivering excellent products that satisfy the needs of modern musicians
and producers - we are confident that the MiniFuse 2 will be a perfect companion to any
computer-based music production and recording setup.
1.1. WHAT IS AN AUDIO INTERFACE AND WHY DO I NEED ONE?
An audio interface is an outboard device that handles processing of audio input and
output. While all laptop and desktop computers these days come equipped with integrated
soundcards, in practice these are only meant for casual use and are, in most cases,
insufficient for the demanding tasks of audio production and recording. Our MiniFuse 2
is an affordable, professional-grade dedicated audio interface that offers the following
advantages over a typical onboard soundcard:
• Optimized for low-latency performance
• Microphone preamp(s) for crisp, present recording of vocals and instruments
• High-impedance input(s) to directly record your guitar or bass.
• Headphone and speaker system outputs for flexible monitoring
• Loopback recording for recording computer audio without any messy hardware
or software configurations.
• Direct Monitoring for monitoring your performance without any processing
latency.
1.2. MINIFUSE 2 FEATURES OVERVIEW
• 2 x combo Mic/Inst/Line XLR inputs with optional 48V phantom power
• 2 x 1/4" TRS balanced line outputs
• 1 x 1/4" stereo headphone output
• 1 x 5-pin MIDI input
• 1 x 5-pin MIDI output
• 1 x USB2 type A hub (low power)
• USB-C interface compatible with PC, Mac, fully USB 2.0 compatible
• Bus-powered
• Up to 192kHZ / 24bits
• Loopback stereo input (at all sample rates)

3. FRONT PANEL FEATURES
The front panel of the MiniFuse 2 provides access to most of the essential features on the
unit.
1. The combo jack(s) accept two different kinds of input - XLR and TRS - allowing you to
connect a variety of microphones and instruments into the MiniFuse. The type of input is
determined by the Guitar and 48V switches next to the input.
2. The Inst switch toggles the high-impedance circuit for the corresponding input.
When recording instruments with pickups, like guitar and bass, using the high-impedance setting
adjusts the internal circuit so that you can plug the instrument directly into the input without having
to first plug into an amp or a direct box. When using other types of inputs, like synthesizers or
microphones, leave this switch in the inactive position.
3. 48V switch turns on phantom power for the input(s). Phantom power delivers a power
current to a connected microphone and may be required to get a good signal out of certain
types of microphones. Please read the following recommendations regarding when and
how to use phantom power:
Only certain types of microphones, like condenser microphones, require phantom power to function
properly. Please check your microphone’s user manual to determine which type it is. Phantom power
may damage some equipment, like certain ribbon microphones. Ensure that you are only using
phantom power with microphones that require it. Do not connect or disconnect microphones while
phantom power is turned on. Turn off phantom power first, then connect or disconnect the microphone.
4. The Gain knob controls the gain of the input preamp. Use it to adjust the volume of the
input to ensure that you are capturing a good signal without overloading. The knob also
features a LED indicator to help with setting input gain. When an instrument or microphone
source is detected, the LED will illuminate blue. If the input signal overloads, the LED will
illuminate red. If this happens, turn down the Gain knob.
High-resolution input metering is available through the MiniFuse Control Center [p.20] application.

5. Monitor Volume knob controls the volume of the signal sent to the speakers (outputs L &
R on the rear panel).
6. Monitor Mix knob controls the mix of direct input signal (Direct Monitoring) and computer
audio playback. Its default position is Fully Clockwise. At minimum position, you will only
hear signal from the interface input(s). As you turn up the knob, you will gradually crossfade
to computer playback. At maximum position, you will only hear computer playback.
Recording live instruments on a computer can sometimes present challenges, depending on your
computer configuration and CPU load. Since your computer processes incoming and outgoing audio
in buffer “chunks”, this can result in delayed playback of the input signal, which can create distracting
echoes that could throw off a performance. Instead of monitoring the input signal through software, the
MiniFuse 2 gives you the option of using Direct Monitoring. Direct Monitoring sends the input signal(s)
directly to the outputs, allowing you to listen to the input(s) directly without any latency introduced by
computer processing. To read more about latency and how to best deal with it, please see the A Quick
Primer On Digital Audio [p.32] section of this manual.
7. Direct Mono switch controls how the input signals are distributed across the stereo
output when using Direct Monitoring. In the inactive position, input 1 is sent to the left channel
(output 1) while input 2 is sent to the right channel (output 2). In the active position, inputs
1 and 2 are turned into mono signals that are sent to both channels; effectively this means
that both inputs will play back centered in the stereo image instead of panned to one
speaker or the other.
The Direct Mono switch only impacts how signal from the inputs is routed to the speakers and
headphones. It does not have any effect on the stereo image of computer playback.
8. The 1/4” stereo headphone output can be used for connecting headphones. The
headphone output mirrors the Monitor Output but has its own independent volume control.
9. Headphone Volume adjusts the volume of the headphone output.
Listening to loud music for prolonged durations of time through headphones can have a negative
impact on your hearing. When using headphones, we recommend taking frequent breaks to give your
ears a rest and avoiding high volumes for prolonged durations.

4. REAR PANEL FEATURES
The rear panel of the MiniFuse 2 provides access to audio and MIDI connections.
1. Outputs - these 1/4” balanced stereo outputs can be connected directly to active
studio speakers or other devices such as amplifiers and mixers.
2. MIDI In - connect MIDI devices to this jack using a standard 5-pin MIDI cable.
Devices connected to this input can be used to trigger and control software
instruments and effects.
3. MIDI Out - this output allows you to output MIDI data from your computer to
control other MIDI-compatible hardware devices.
4. Hub - this convenient USB port allows you to plug in other USB devices, like
thumb drives or MIDI controllers.
While the Hub port is sufficient for powering most controllers and portable drives
up to 250mA, it may not provide enough power for some devices that require higher
power draw. In these situations, we recommend plugging these devices directly into your
computer, or into a separate powered USB hub.
5. USB - connect the interface to your computer by plugging the supplied USB cable
into this port and your computer. This connection provides power to the interface
and enables communication between the interface and your computer.
6. Kensington lock - this optional security slot can be used for securing the interface
using a Kensington lock cable.
