DESCRIPTION
The MS-700 Optimum Amplifier is a fully integrated networked classroom amplifier and wireless
microphone receiver. This amplifier has network-based intercom, paging and emergency notifications,
and provides full-duplex audio. It is easy-to-use, easy-to-install, and has a simple user interface software.
The entire unit utilizes Power over Ethernet (PoE+). Intercom and paging functionalities† are built-in.
When used in conjunction with an Uninterruptable Power Supply (UPS), during emergencies, paging can
still be heard, even when the power goes out. This unit can be installed as part of the SAFE (Signal Alert
For Education) System®.

PROCESS
1. Physically install components in the room such as speakers and/or AV Touch Wall Control
to MS-700.
2. Confirm BLE (Bluetooth Low Energy) dongle is connected to USB port.
3. Apply Power by connecting the MS-700 to the POE Switch.
a. Monitor the display during power up and note the firmware version, PoE LLDP Detection
and IP Address
4. Install the Device Configuration App (For Apple and Android phones search for the Device
Configuration App by Audio Enhancement.) For more information on the Device Configuration
please view the Device Configuration Guide document.
5. The app is available on iOS and Android app stores under the name Device Configuration.
6. Start the Device Configuration App. (Figure 1)
7. Select the BLE dongle for the MS-700 you are configuring. If Multiple BLE dongles are found,
select the dongle with the largest signal strength. Note that all MS-700s with a BLE dongle
in range of the cell phone will be displayed. Give the application time to gather data before
selecting a system to connect to. (Figure 2)
8. Set up school information. (Figure 3)
9. Input and/or confirm network configuration information. Note the values for your system will be
dierent than those shown in the example. (Figure 4)

10. Set default audio input levels. (Figure 5)
11. Set audio output levels. (Figure 6)
12. Set up the equalizer. In most cases the default settings work best in the classroom. (Figure 7)
13. Link classroom microphones.
14. Remove the Bluetooth Dongle (recommended, but not required).
15. Start EPIC, update the firmware, and continue the setup using the EPIC software.

XD TEACHER MICROPHONE
LINKING
1. With the microphone o, press the Link
button on the front of the amplifier or side of
the BEAM (Look for the blinking yellow LED).
2. With the microphone o, press
and hold REC button. Then
promptly press and hold PWR until
microphone is linked.
3. Successful microphone linking will produce a beep through the system, and on the front of the
amplifier you will see an additional green LED.

XD STUDENT MICROPHONE
LINKING
2. Press and hold the PWR LINK
button on the back of the XD
Student Microphone.
3. While holding use your thumb to slide the TALK button up into to the on position. Successful
linking will produce an audible beep as well as an additional green LED.
1. With the microphone o, press the Link
button on the front of the XD Receiver.
(Look for the blinking yellow LED)

CHARGING YOUR
XD MICROPHONE
1. Charge the microphone at the end of each day.
2. Connect the USB-C plug of the charger to the DC input terminal of the microphone.
After connecting the microphone to the charger, the charge indicator red indicates the
charging status.
3. When the charge indicator stops blinking, the microphone is fully charged. If the charge indicator
is blinking rapidly it means that the USB-C isn’t fully inserted.
LINKING THE MEDIA CHANNEL
1. The microphone cannot be linked to the Media channel unless MIC 1 and MIC 2 channels are on.
2. Make sure the microphone needing to be linked, either the Teacher or Student, is turned o.
3. Confirm that both Channel 1 and Channel 2 mics are on and connected to the amplifier.
. Follow XD Teacher or XD Student Microphone Linking section instructions.
5. In around 10 seconds you should hear a beep and the amplifier LINK LED will be solid yellow.

1. Press SELECT to choose the desired source to control. An LED will illuminate to indicate the
selected source. OWN will control the level of the microphone currently in use. CH3 will control
the other microphone if a second microphone has been linked.
2. Press the up arrow to increase the level of the selected source or the down arrow to decrease
the level.

TROUBLESHOOTING
REBOOT BUTTON FUNCTIONALITY
Reboot
Press button (5 seconds).
Factory Reset Procedure
Press for 10 seconds wait for Green LED flashes and release.
Rescue Mode
Press until Red light illuminates or disconnect power, press and hold the reset button while
applying power.
MS700 AND SPEAKER VOLUME
If you have speakers connected to an MS-700 with the volume at max and the sound is very quiet, the
OHMs settings need to be changed in the software. The MS-700 will be defaulted to 2 OHMS and should
read just when speakers are connected, but if this does not occur increase the OHM setting in the EPIC
MS-700 software and volume will be corrected.
“SIP NOT CONNECTED”
Verify that the SIP settings are correct on the device. Try pushing settings from EPIC again- specifically
from the configure tab, as pushing settings from the devices list does not push SIP settings.
REBOOTING ISSUE
If MS-700 is constantly rebooting and has peripherals plugged in, such as an ITC, it might be pulling too
much power. Try lowering the Nominal Speaker Impedance option in the advanced Audio Settings by
editing the device in the devices list.
NO AUDIO
If there is no audio going through the speakers (bells, paging, intercom, teacher mic) check the audio
output to see if there is any audio passing through there. This can be done by connecting a pair of
wired headphones to the audio out of the MS-700 and playing audio through the MS-700. If you hear
audio through the headphones, it is most likely not a problem with the MS-700 and more related to the
speakers or speaker wiring.
