The MX-Stream is a universal, transport-only network device that can take any online or network
streaming service to your integrated amplifier or DAC. All you need is an existing USB Class 2.0 Audio
input. The MX-Stream’s digital audio circuitry is a complete custom design from scratch. We have
separate power supplies and high-end voltage stabilization components for all the different PCB units.
We have advanced re-clocking – even the main CPU is operated by an audio optimized clock, which is
completely unheard in typical streaming solutions, as they typically run with standard CPU clocks like
those in regular computers. Every incoming digital signal is cleaned up from the very beginning. All audio
files that come in and out, are the best they can be by eliminating all unwanted noise that can be found
in common streaming solutions. With an optimized software, we were able to push this high-tech
hardware design to its absolute limits. All of this resulted in the first near-zero jitter streamer we have
ever seen.

The MX-Stream is the perfect add-on for any integrated amplifier or DAC with USB B input. Not only is
the technology inside the MX-Stream complete cutting-edge high-end, every analog circuit in integrated
analog amps displays increased performance, when digital circuits and power supplies are kept separate
from the analog circuitry. By squeezing in a lot of digital circuits, additional high frequency distortion
across the entire system can be observed. Coming from the other direction, huge power supplies for pre
and power amps with lots of magnetic radiation impact digital circuit performance negatively. By
keeping streaming and amplification separate we can achieve our true high-end sound vision to greater
effect and at a more affordable cost, while also guaranteeing the longest lifetime of our amplifiers and
streamers.

Installation and first use

Setting up network connection
The unit can be connected to the network/internet via wired or wireless connection.

1. Wired connection: Connect a LAN cable from your router to the socket Ethernet on the back panel. Download the
MX-Stream App (available for Android and iOS). Make sure your mobile device is on that same router’s network,
open the App and it will automatically find and connect to the MX-Stream. You can now control your MX-Stream.

2. Wireless connection:

Make sure the supplied antenna is mounted to its connector on the back panel

- Turn the MX-Stream on and wait until the NET LED is blinking alternately in short intervals. This means the

boot up sequence has been completed, but a network/internet connection is NOT established.

- Open the Network Settings on your mobile phone and you

will now find a network called Musical Fidelity. Connect to
that network and a welcome page will open automatically
(similar like signing in to a hotel room WIFI).

Should you encounter problems at this step, for
example if the signing in process isn’t initiated
automatically, we recommend trying with different
devices (other phones, tablets or also laptops work).
The sign-in typically opens automatically, but there
are some background circumstances which could

“confuse” your device, which won’t make it open the

sign-in automatically.

- Go through the first config wizard:

4. Simple/Full Options - choose between a simplified or the full options menu. Both options will set you off with bit-
perfect playback quality. Beginners might find the simplified options easier to navigate, while expert users will benefit
from all the control and digital playback transparency that the full set has on offer.

5. Network - here you can connect to a wireless network, a list of available WiFi networks is shown. Select your

desired WiFi network, type in the password and tap on the “Connect” button. The unit will reconnect to selected WiFi

network when first setup will be completed.

6. Music - manage all the network music locations, add NAS drives

After the first setup assistant is complete the MX-Stream will connect to the specified WiFi network and close its
internal Musical Fidelity network (the network you have just connected to for the WiFi setup in the previous step).
Your MX-Stream is fully operational, once the NET LED on the front panel lights up constantly.

Your phone will automatically connect to your home WiFi again. To make sure, quickly check your phone’s settings
and see if it is correctly connected to your home WiFi. Download the MX-Stream App (available for Android and iOS),
open the App and it will automatically find and connect to the MX-Stream. You are now ready to control your MX­Stream.

Once you have your MX-Stream up and running, make sure that one of the first things you do is to
search for a new Firmware Update under Settings -> System -> System Update.

BT Connection

Pairing with Android devices

Open Settings and tap on BT. Turn on BT and tap on Scan. All found devices will show up now, tap on Stream Box S2
Ultra and confirm the connection.

BT pairing with Apple devices

Open Settings and tap on BT, turn on BT if it is not activated yet. Your device will automatically start searching for
available devices. Tap on Stream Box S2 Ultra and confirm “Pairing” on your Apple device.

Control the MX-Stream

The control screen is divided into three parts: Browse, Playback and Queue

Browse works as a home page. Here you can go to any of the following pages.

Music library - here you can find all the available Music in your network and connected directly to the
streamer: USB or NAS. Your library will be created automatically and sorted using the available
metadata. (Some of these options are shown only when available)

Web radio – here you have access to a list of available internet radio stations. You also have access to
a list of selected internet radio stations under Pro-Ject Selection.

BT connection – enables the BT input. Play music from connected BT devices.

USB/PC – Activate the USB/PC bypass input. You can connect a PC/Laptop/Phone or other streaming

devices with a USB audio output to the USB B input on the MX-Stream. The input will be detoxed and
cleaned up by the MX-Stream and forwarded to your connected DAC.

Shairport-Sync – This option lets you connect to Apple devices using the Airplay protocol. You need to
select this input first and then the MX-Stream will show up as an Airplay option on your Apple devices.
