OPERATING INSTRUCTIONS
FM TUNER - To enable the FM Tuner press the “Mode” button
either on the front panel (page 2 button 12) or on the remote
control (page 3 button 2) until “RAD” appears on the display.
Do not forget to connect the antenna cable for the tuner to
work properly.
Automatic Scanning - Press the Play/Pause Button on the
front panel (page 2 button 15) or the U/SD button on the
remote control to execute an automatic sweep and save the
radio frequencies where a station is present. The MX350 will
assign an ID number to each station which also corresponds
to the memory number. With this process completed, the
MX350 will go back to memory 1.
Browse Stations - Using the front panel buttons
Press once the forward button on the front panel (page 2
button 13) to listen to the radio station memorized on the
next memory position or press once the backwards button
(page 2 button 14) to listen to the one stored at the previous
memory position. Long pressing any of these buttons will
either increase or decrease the sound volume. There is no way
to fast-browse the radio channel memories using the front
panel of the MX350.
Browse Stations - Using the remote control
Press the play/pause button (page 3 button 4) to listen to the
radio station memorized on the next memory position or
press the EQ button to listen to the radio station memorized
on the previous memory position. You can also directly select
a specic channel using the numerical keypad. Just type the
ID number of the memory you want to listen to.
Manual Tuning and Fine Tuning - On the remote control only,
it is possible to manually tune or ne-tune. Pressing the
forward button (page 3 button 5) will increase the tuning
frequency and pressing the backwards button (page 3 button
6) will decrease the tuning frequency.
MP3 PLAYER - The MP3 player is automatically enabled as
soon as you insert a USB stick or SD card. Whatever is playing
is interrupted and the program on the data device will be
reproduced. If the USB Stick or the SD card are already
inserted, press the mode button (page 2 button 12; page 3
button 2) until the display shows USB or SD.
Reproduction - Any present MP3 tracks are played
automatically as soon as a data device is inserted. The MP3
les may be either in the root of the device or in folders. Other
le types will be ignored if they exist. 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 forward button to play next song and
the backwards 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.
Sorting 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.
U/SD function button - On the remote control, press the U/SD
button to cycle between the USB device and the SD card
device, but also allows playing the tracks in both devices as if
they were one.
Pairing Bluetooth Device - Press the “Mode” button either on
the front panel (page 2 button 12) until “bt” appears ashing
on the display. On yor mobile device search for “NEXT MX350”
and type “2020” as password. The “bt” stops ashing.
PRIORITY ANNOUNCEMENTS
The MX350 supports a ducking function where, when a
priority signal is present, the volume of the regular signals is
reduced to improve the message intelligibility. The Mic 1
input and the Chime function are considered as priority
signals. When you press the Chime button or talk to Mic 1, the
other signals are reduced in level. The level values are dened
individually. Both the Chime volume potentiometer and the
Ducking potentiometer are located at the rear panel (page 2).
CONNECTIONS
INPUT CONNECTIONS
In the MX350, the Auxiliary mode disables the Tuner/MP3
module and enables working only with cable connected
equipment such as CD Players, Tuners, Turntables or others.
Press the MODE button (page 2 button 12; page 3 button 2)
until the display shows “AUX”. There are 3 auxiliary RCA
inputs, and 4 microphone jack inputs (not balanced). A signal
output is also available as RCA outputs where a recording
device or an external amplier can be connected.

NEXT Audiocom | MX Series
LOW IMPEDANCE OUTPUT
To use the MX350 as a regular mono low impedance amplier
connect the speakers to the binding posts as shown above. Be
careful not to switch polarities between speakers to minimize
comb ltering and bass cancellation eects due to “out of
phase” speakers. The minimum impedance allowed by the
amplier is 4Ω (two seakers of 8Ω connected in parallel).
100V LINE ZONE OUTPUT
The MX350 allows for the conguration of up to 6 different
zones. These are all 100V outputs for distributed lines. These
require 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.

SERVICE
5NEXT Audiocom | MX Series
The high impedance also allows the use of more speakers as
long as 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 MX350 this means that the sum of the power ratings
of all the speakers connected in all 6 zones cannot be higher
than 350W. 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
instead through excessive heat on the speaker’s coil.
WARNING!
Though the MX350 allows it, never have a low impedance
speaker working at the same time as the Zone distributed
lines for a long period of time.
WARNING!
RISK OF ELECTRIC SHOCK – Never try to connect or disconnect
the 100V distributed lines with the amplier powered on.
Always disconnect the MX350 from the mains before
attempting any changes to the wiring or connections.
