Overview: The Russound MBX-AMP WiFi Streaming Zone Amplifier is designed for adding high quality audio streaming high-resolution audio anywhere in your home, while being easy to install and configure. The 2-channel amplifier offers 50 watts per channel into an 8Ω load (70W @ 4Ω), and features WiFi streaming (wireless or hardwired), Bluetooth Audio streaming, and audio playback via a rear-panel USB port, along with both optical digital and analog inputs.


Network Connection: The MBX-AMP can be connected to a home network, either wired or wirelessly (WiFi). Wired and WiFi setup options let you select a specific type, which then disables the other option. A third Automatic setting (default) allows either type of connection to be made and will take priority over a hard-wire connection.

  • WiFi: The MBX-AMP features built-in 2.4GHz/5GHz dual-band 802.11ac WiFi for streaming audio wirelessly, including Hi-Res audio up to 24-bit/192kHz. Setup for the MBX-AMP is done by first downloading the Google Home app, available from the Apple App and Google Play stores. Once the device is connected to your network, the Google Home app will automatically "see" the MBX-AMP and can be selected. This is the fastest and preferred method of setting up a wireless connection. Other wireless connection setups include:
    • iOS Device: Wireless setup can be initiated with an iOS device on the same WiFi network by selecting the MBX-AMP as an AirPlay speaker.
    • Access Point: The MBX-AMP will broadcast an SSID that your phone or tablet can connect to, allowing WiFi setup.
    • Hard-Wired: A temporary direct Ethernet connection will give access to the amp's configuration, allowing a wireless configuration.
  • Wired: A rear-panel RJ-45 Ethernet port lets you make a hard-wired connection to your router via a CAT-5 connection.

Configuration: The MBX-AMP has a programming feature called Web Config. Web Config is an onboard hosted web page used for unlocking and configuring the MBX-AMP. Web Config can be accessed by entering the IP address or Hostname in any web browser on a smartphone, tablet, or laptop that's connected to the same network as the amp. This allows the amp to be completely and easily configured from your device. The first time you navigate to the MBX-AMP Web Config page, it will automatically open in First Time Setup mode. The First Time Setup is designed to help configure basic settings as well as provide for a quick method of enabling Chromecast Built-in Audio.

Note: All setup and configuration must be done through a browser-based controller using a network connection. When the MBX-AMP is initially shipped, it will only operate in a "locked" state. In this state, no audio or control is available. In order to unlock the system, valid Russound Certified Installer credentials must be entered using the convenient Web Config browser-based configuration utility. Please contact your sales advisor for details.

Control: The MBX-AMP can be controlled using 2 methods:

  • Russound App: The Russound App (available from the Apple App and Google Play stores) lets you operate the MBX-AMP from your Apple or Android phone or tablet, giving you control of the amp from anywhere inside your network's range. This is also a convenient way to change the Volume, Bass, Treble and Loudness settings, and allows other people to control the sound from the area they're in.
  • XTS7 Controller: The Russound XTS7 Wall-Mounted Touchscreen Controller (sold separately) is a stylish in-wall touchscreen that runs an embedded version of the Russound App. This allows the same control that's available on your smartphone or tablet without having to use your device to change the volume or make a music selection. The XTS is an IP-based network device that gets connected to the same router the amp is connected to.

    Note: In order to prevent unauthorized changes to configuration settings, a default password (see owner's manual) has been created that will be required to be entered prior to changing any configuration settings. The default password is user-changeable in the Web Config.

Chromecast: The MBX-AMP features built-in Chromecast for Audio support, letting you stream music from popular music services such as Spotify, SiriusXM, vTuner, Tunein, and Deezer, all from your smartphone or tablet that's connected to the same network and running the Google Home app. Russound now offers Pandora music streaming service via the latest firmware update (v. 3.0 or higher). The MBX-AMP can be configured to automatically update as newer firmware is available. To take full advantage of Pandora music streaming, make sure you are using the latest version of the Russound App (v. 1.5).

Note: A subscription may be required for some music streaming services.

AirPlay: The Russound amplifier supports Apple's AirPlay technology, letting you listen to your iTunes library or other audio content from any AirPlay-enabled Apple device connected to the same network. When AirPlay is selected from iTunes or an iOS mobile device and music is sent to the MBX-AMP, the amplifier will activate and select the internal streamer as the source. Using AirPlay will also automatically power on the amp when music is cast to it. AirPlay steaming can output full metadata to iOS/Android apps or XTSPlus touchscreens.

AirPlay 2 (Firmware Update): The Russound MBX-AMP now supports AirPlay 2 audio streaming via a firmware update (2.0.23). The firmware update can be found in the Admin-Firmware Update section of the Web Config menu. If your MBX-AMP is configured to receive automatic updates, the AirPlay 2 update will install automatically when available. AirPlay 2 features include:

  • Multi-Brand Synchronization: Allows you to synchronize audio between the MBX-AMP and any other brand of AirPlay 2-compatible products.
  • Siri Voice Control: You can now use Siri to play and control your favorite music apps including Apple Music, Pandora, and more.
  • Uninterrupted Music: AirPlay 2 will continue to play your music uninterrupted if you receive a phone call on your playback device.

UPnP: The MBX-AMP is UPnP (Universal Plug and Play) compatible, allowing it to stream music from other UPnP compatible storage devices connected on the same network.

Additional Features

Bluetooth Audio: The MBX-AMP lets you steam audio from a Bluetooth enabled device. A simple pairing process allows you to connect your device using the front panel controls. When Bluetooth audio playback is initiated, the amplifier will automatically switch to the Bluetooth source.

Note: Bluetooth functionality is limited to audio streaming. Hands-free phone call operation is not supported.

TV Integration: The MBX-AMP's advanced TV integration feature allows it to play audio from your TV as well as share it with other playback devices on the network. The MBX-AMP includes an IR sensor that can be mounted to the front of the TV and plugged into the rear-panel IR Input, allowing it to pass the IR signal from the TV remote to the Russound amplifier. Through a "learning" procedure, the MBX-AMP can then follow the TV's Volume Up/Down and Mute functions.

Expansion: The Russound MBX-AMP streaming amplifier can be mixed and matched with other MBX-Series components for a flexible and versatile system design that can be expanded to up to 32 rooms of streaming audio. When paired with a Russound multi-room controller, such as the MCA-66 or MCA-88, a system can be expanded with up to 8 independent audio sources and up to 48 rooms of distributed audio.

USB: A rear-panel USB port (Type-A, 2.0) is provided for playing audio from a USB flash drive or USB hard drive. Supported formats include:

  • MP3 (CBR, VBR)
  • WAV (8- & 16-bit)
  • OGG Vorbis (8- & 16-bit)
  • FLAC (8- & 16-bit)
  • AAC
  • AAC+ (up to 24-bit/192kHz)

Quick Access Buttons: Two numbered buttons (1 & 2) can be used for quick access of up to 2 of your favorite audio sources, similar to radio preset buttons. Pressing and holding either button will store the currently playing selection. A quick tap of the button lets you quickly access and start playing that selection.

Subwoofer Output: A single RCA Subwoofer jack provides a 160Hz low-passed audio signal for passing to a powered subwoofer or subwoofer amplifier (sold separately).

How can I make this work for 4 zones? Same audio source? Need control from my phones to turn on and off and isolate zones.
nigel  Mar 05, 2023
1 answer
Greetings Nigel, and thank you for your question. You would need 4 of these Russound MBX-AMPs. One for each controllable zone. Or you get 4 of the MBX-PRE, and run those into an 8 channel amplifier to give you control over each individual zone.
hogan  Mar 05, 2023 (Staff)
Will this function as another zone on a Russound MCA-66 if both are plugged into an ethernet connection?
ian  Dec 28, 2022

This can be paired and used with the MCA-66 to act as another zone.
zachary  Dec 29, 2022 (Staff)
Do you know exactly what DAC chip and amp are used? Russound says it's a "Texas Instrument Class D", but there are many of them...

That information was not provided to us in any of the details we received on the unit and is also not listed on their site for it and recommend contacting their support by calling 866-888-7466 to check if they can give the specific model being used at this time

This amp is compatible with those speakers
jason  Apr 18, 2021 (Staff)
Is this amp Airplay 2 compatible? This could finally be what we've been looking for!

That unit has Airplay but not Airplay 2. If you need something with Airplay 2 you might consider the Bluesound Node 2i
