7Russound MBX-AMP Installation Guide
Step 1. Connect your Loudspeakers to your MBX-AMP
Speakers connect to the MBX-AMP using two wires, a positive 
(+) and a negative (-). Remove approximately 3/8" (10mm) of 
insulation from the ends of both conductors of the speaker 
wire and twist the bare wires of each cable tightly. Loosen the 
right positive speaker terminal and insert the corresponding 
bare speaker wire into the gap on the side of the terminal. 
Tighten the terminal. Repeat for the right negative terminal 
and then repeat the process for the left positive and negative 
terminals.
Make certain that no bare cable strands touch any additional 
speaker terminals or wires.
Step 2.
Insert the power cable into the rear socket of the MBX-AMP 
and insert the other end into your AC wall outlet.
The MBX-AMP will take about 30 seconds to fully power 
up. When ready, the front panel LED will illuminate either 
green or yellow. Green means that a network connection 
has been made and yellow means that the unit is ready but 
not yet connected to a wired or wi-fi network. See below for 
Network Connection information.
Step 3. Network Connections
The MBX-AMP requires a network connection in order to 
use the MyRussound app or an XTSPlus touchscreen for 
system control. The network connection is also used for 
accessing all streaming audio sources other than Bluetooth 
or any connected USB drives. The MBX-AMP works with 
Wired Ethernet connections (preferred) or with wireless 
connections using Wi-Fi.
A. Wired Ethernet Connection (Preferred)
Connect an Ethernet cable from an open network port to 
the port labeled “LAN” on the rear of the MBX-AMP. The 
front panel LED of the MBX-AMP will turn green when the 
network connection is successfully established.
B. Wi-Fi Connections
The MBX-AMP can also be connected to the network utilizing 
Wi-Fi. There are four ways to configure the Wi-Fi settings. 
The easiest method is using a phone/tablet to transfer 
existing Wi-Fi settings.
Option B1 Recommended for all systems
The MBX-AMP can be quickly added to an existing Wi-Fi 
network by utilizing the Google Home app. The Google 
Home app is also used to configure the MBX-AMP’s for 
Chromecast Built-in for Audio. If you do not yet have the 
Google Home app on your device, download and install it 
from the Google Play Store or Apple App Store.
Open the Google Home app and it will automatically 
discover the MBX-AMP on your network. It will be listed as 
“MBX-AMP-XXXX”, with XXXX being the last 4 digits of the 
MAC ID of the MBX-AMP. This is done in order to make it 
easier to identify multiple MBX devices when configuring a 
large system in a home.
1. From the Google Home app, find your MBX-AMP either 
on the main screen or under “Devices” and choose “Set Up”. 
2. Choose a name for the MBX-AMP. The name you 
choose will be name that is visible within the MyRussound 
app and any other network based interface to identify the 
MBX-AMP. There is a list of possible room names as well 
as an option to use a custom name “Add a custom room”.
