OPERATING INSTRUCTIONS
MP3 PLAYER - The MP3 player is automatically enabled as
soon as you insert the USB stick. If the USB device is already
inserted, press the mode button (page 2 button 12; page 3
button 2) until the display shows USB. The MP3 les may be
either in the root of the device or in folders. Other le types
will be ignored if they exist.
Reproduction - Any present MP3 tracks are played
automatically as soon as a USB data device is inserted. Press
play/pause button on the front panel (page 2 button 15) or
the remote control (page 3 button 4) to interrupt the
reproduction and press again to resume. Press the Next
button to play next song and the Previous button to play the
previous song. You can also directly input the number
correspondent to the track you want to listen. Just type the
track ID number.
Ordering MP3 Tracks
You may want to play your tracks in a specic order. Change
the name of the tracks inserting the number correspondent to
the order you wish followed by a dot. Ex.: 1.track_x.mp3,
2.track_y.mp3, etc.
Repeat
The repeat function can be activated only on the remote
control. Press the repeat button (page 3 button 12) once to
repeat the current song. Press again to repeat all songs like a
playlist.
BLUETOOTH - To enable the Bluetooth mode of operation,
press the Mode button until the words “bt” appear on the
screen followed by an intermittent dot. This intermittent dot
signies that the MX120 is waiting for pairing to be
completed. On your smartphone or tablet enter the Bluetooth
menu and search the available devices for “NEXT MX120”. If a
password is requested write “2020”. When pairing is
successful, the intermittent dot on the MX120 disappears. The
MX120 is also moved to the paired devices list.
AUXILIARY MODE - In the MX120, the Auxiliary mode disables
the MP3/Bluetooth module and enables working only with
cable connected equipment such as CD Players, Tuners, or
others. Press the MODE button (page 2 button 12; page 3
button 2) until the display shows “AUX”.

CONNECTIONS
INPUT CONNECTIONS
The MX120 provides 2 microphone inputs and 2 auxiliary line
inputs. Mic2 and Aux1 inputs share the same channel. To
select which will be the active input, use the selector switch
on the back (page 2 number 4). Mic2 input is also phantom
power capable and is also selectable through the same
switch.
When phantom power is enabled, be careful to choose the
right cable for your microphone. It must be a balanced type
cable to provide phantom power eectively.
On the other hand, the Mic1 input must be an unbalanced
XLR to TS ¼” cable. It is also important to use a microphone
that can be switched on and o.
PRIORITY INPUTS
The MX120 supports a priority function where when a priority
signal is present, the volume of the regular signals is cut down
to improve the message intelligibility. The level values are
dened individually. In addition to Mic1 input, the MX120 also
has two more inputs that are managed as priority inputs.
These are intended to provide a means to connect an already
existing system, like an announcement or a security system.
HANDS-ON
4
NEXT Audiocom | MX Series
The MX120 is prepared to accomplish this in one of two ways.
If the existing system has a “Line Out” output, it can be
connected to the priority line input connector on the back of
the MX120. If this is not possible, the MX120 still has the
possibility of connecting the 100V output of this system to the
100V priority input next to the line input. The rear priority
inputs volume is dened on a potentiometer on the back
panel.
ATTENTION! – Only one of these methods can be used. Do
not use both the line input signal and the 100V signal at the
same time.
100V DISTRIBUTED LINE OUTPUT
The MX120 is designed as a 100V output amplier for
distributed lines. This requires the use of speakers designed
specically for this kind of output. These speakers will have a
transformer as the input, normally with more than one power
tap. The 100V distributed line is the best method when you
need to deploy many speakers over a wide area. The higher
voltage allows for a lower current at the same power rating,
which in turn allows the use of longer and thinner cables with
little loss.
On the table below you can nd the maximum distance a
cable can deliver the amplier full power.
The high impedance also allows the use of more speakers if
the total sum of the power ratings congured in those
speakers is not higher than the power rating of the amplier.
For the MX120 this means that the sum of the power ratings
of all the speakers connected cannot be higher than 120W.
For a safe use we recommend it to be 10 to 20% lower to allow
for a little headroom to handle peaks from the music program.
Using more than this will likely damage the amplier, or at the
minimum cause unpleasant distorted sound that given
enough time, will damage the speakers through excessive
heat on the speaker’s coil.
