3Russound DMS-3.1 Installation Manual
Introduction
Russound’s DMS-3.1 is a digital media streaming device that is capable of 
playing digital audio content from various sources. Streaming refers to the 
delivery method of the content rather than to the content itself. Based on 
the installation method, the DMS-3.1 can play a wide variety of content for 
your listening pleasure. Software upgradable, your DMS-3.1 will support new 
features as they become available. 
The DMS-3.1 has three separate streaming media players with corresponding 
analog audio outputs that can feed multiple ampliers. This allows 
independent content selection by dierent rooms simultaneously.
Another benet is that each streamer can have dierent account credentials 
if desired. This allows streamer 1 to access one user's accounts and favorite 
stations, while streamers 2 and 3 can do the same for other users in the home. 
No one has to share their stations and favorites with anyone else in the home if 
they don't want to do so. 
The DMS-3.1 is also an AirPlay accessory that can stream audio content from 
AirPlay-enabled sources such as an Apple iPod touch, iPhone, or iPad that is 
running iOS 4.2 or greater. In addition, computers running iTunes® 10 or newer 
can stream content via AirPlay to the DMS-3.1. AirPlay will have priority and 
override any selected source of audio content currently playing on any of the 
three streaming outputs.
The DMS-3.1 is connected to the Local Area Network in a home via a hardwired 
Ethernet connection for access to digital audio content. If used with an MCA-
Series controller and a supported user interface, the DMS-3.1 can access and 
playback digital audio les from LAN connected DLNA / UPnP media servers. 
Additionally, if connected to the internet and used with an MCA-Series 
controller and supported user interface, the DMS-3.1 can stream content from 
multiple services, including Pandora®, Spotify®, SiriusXM®, TuneIn® Radio and 
vTuner® Radio.
Note: Some of the services may require paid subscription accounts.
A built-in AM/FM tuner with RDS feedback adds local radio as a listening 
choice, and USB ports accept connections from USB storage devices using 
FAT16 and FAT32 le formats for audio content playback if used with an MCA-
Series controller and a supported user interface.
