2. MOUNTING THE MPA400 SYSTEM
2.1 Mounting
The MPA400 uses a NEMA 1 housing and is to be located indoors in a climate-controlled building. When
mounting the housing, note the CCA orientation in the housing. It is recommended that the housing is
mounted such that connections are made on the same end as the connectors on the CCA. Fasten the
MPA400 to the wall surface using appropriate fasteners for the wall. Always follow local codes and safety
practices. Wall fasteners not included.
Figure 3 –Mounting

ultra-hyperspike MPA400-MAN-IPFORMER Rev B | Copyright © 2020 USSI
See cover page for export control
Page 9
3. MAKING CONNECTIONS
The MPA400 system is configured such that connections are made through the conduit knockouts. It is
recommended that connections are made on the same end as the connectors on the CCA. See Figure 4
for reference. Although connections can be made in other locations, appropriate space and wire routing
mechanisms are not provided when routing into other locations.
Figure 4 - Recommended Connection Locations
CAUTION
When making outside connections, ensure proper protection and damage prevention actions are
taken to avoid impacting internal components. Tools making inadvertent impact with internal
component or metal shavings could result in functional issues void of product warranty.
MISE EN GARDE
Lors de l'établissement de connexions à l'extérieur, assurez-vous que des mesures de protection
et de prévention des dégâts soient prises pour éviter d’endommager les composants internes.
Des outils ayant un impact accidentel avec des composants internes ou des copeaux métalliques
pourraient entraîner des problèmes fonctionnels qui ne seraient pas sous garantie.

3.1 Connecting HyperSpike®Speakers
The MPA400 includes a 4-position output connector that will accept 16-26 AWG wire. See Figure 5 for
speaker output connections. Install positive (+) speaker wire(s) in pin 3 (red wire shown) and negative
speaker wire(s) in pin 4 (black wire shown).
Note: Wire colors are for reference only, see speaker manual for wire color and polarity.
Figure 5 - Speaker Connection
IMPORTANT
Ensure wires are installed with proper polarity. Improper polarity between various channels will
negatively impact speaker performance.

Page 11
3.2 Connecting to a Wired PoE Network
The MPA400 has a standard RJ45 network jack and requires a standard Ethernet cable (CAT5e or better).
If optional 24 VDC power is not used, the network connection will need to provide PoE+ or 4PPoE power.
Figure 6 - Network Connection
3.3 Connecting Optional 24VDC Power Supply
The MPA400 includes a 2-position input connector that will accept 16-26 AWG wire. See Figure 7 for power
supply connections. Install positive (+) power wire in pin 1 (red wire) and negative power wire in pin 2
(black wire). Wire colors shown are for reference only.

4. COMMISSIONING
4.1 Post Installation System Check
1) Check to ensure all wiring connections are secure:
oSpeaker wiring (check polarity of each speaker connection)
oNetwork Connection
o24VDC Power (Optional)
2) Verify Network connections and that a DHCP Server is available within the network.
4.2 Power-up Sequence
1) Enable Power
2) MPA400 will acquire an IP Address and announce it on the speaker output.
3) By default, the device will announce itself to a Syn-Apps System, System Status LED and
Application Status LED turn solid.
4.3 Managing Sources and Use of the MPA 400
1) Login
a. Use your web browser to log into the MPA400 Web Interface by typing the IP Address into
your browser.
b. Use the user "admin" and the appropriate password provided on the sticker on the backside
of the device.
2) Configure your Sources
For the configuration of your sources, the following source types are available:
•Syn-Apps → Announces the MPA400 as an audio device in a Syn-Apps system
•Barix Radio → Plays Barix Radio as http stream without any further configuration
•RTP → Configures the MPA400 to receive an RTP stream
•HTTP → Configures the MPA400 to receive an HTTP stream
•SIP → Configures the MPA400 to be a SIP client
•Local File →Allows to play audio files which are locally stored on the MPA400

Page 13
Please refer to the help description in the user interface to properly configure your sources.
Please refer to the help description in the user interface to properly configure your sources.
Individual Volume can be set for each of the sources.
Figure 8 - Sources Page
3) Prioritize you Sources
Multiple sources can be configured at the same time and are played according to their given priority.
•Priority 1: Highest priority
•Priority 5: Lowest priority
Management of priority means that a present stream will be played over another configured stream.

ultra-hyperspike MPA400-MAN-IPFORMER Rev B | Copyright © 2020 USSI
See cover page for export control
Page 14
Example of a Priority System
•Priority 3: HTTP Radio Stream playing Background music.
•Priority 2: RTP Streams playing adds over the background music. Background music will stop
as soon as the RTP stream is present
•Priority 1: SIP call playing emergency calls. Background music or add will be stopped as soon
as SIP call is present.
4) Manage Local Files
Use the menu item "Audio Files" to manage your local files for the source type "Local Files".
Figure 9 - Audio FIles Page
Note: Only MP3 Files are supported for Local Files at the time.
5) Control the MPA400
Once the sources are configured, the MPA400 will start playing them accordingly. Master Volume
of the MPA400 can be controlled on the "Settings" page of the web interface.

Figure 10 - Settings Page
6) Monitor the MPA400
The "Source Status" page on the web interface will show you the actual status of the sources of
the MPA400. Every source status also includes a counter indicating how many times the actual
source has been played.
Figure 11 –Speaker Status Page
