controls). Battery status can be checked on internal OLED display or looking the LED status on front
❷.
BATTERY SUBSTITUTION
Open transmitter cover and insert the battery following polarity indicated.
ANTENNAS
MTP41S is supplied with a couple of antennas. According to the working band, different antenna
models can be supplied. All the models have black cap and a black label with code in white colour.
For more details see the below table.
In order to help the user to connect the correct antenna, the
display shows the antenna code during the switch on of the
transmitter and during the tuning selection after a change of
frequency range. (ex. if the user changes the frequency from 566
to 672 MHz, the display shows Ant. 732)

First one gives information of antenna to be used.
The number displayed is the center-band of the antenna to be
used.
The second menu gives indication on product:
- product id (MTP41),
- the firmware release (ex. 1.30.0A),
- the band in extended format and
- the serial number.
Keep selector pushed to hold this menu!
Major info are displayed:
- Current channel/group (i.e. CH:00 GR:39)
- Current frequency (i.e. 566.000 MHz)
- Mic gain (i.e. AF: +00dB) and high pass filter (i.e. HP:60 Hz)
- If in the top right there is “RF 50” or “RF 10”, the transmission is
active respectively at 50mW or 10mW
- On left side, the battery bar is displayed
MTP41S can recall configuration presets.
“FACTORY” recalls the Wisycom factory configuration.
“USER” recalls the user configuration (the transmitter configuration
is copied into the USER using the “save to” submenu).
All “USER” menus are not locked by default, thus this is quick way to
unlock features!
When the user changes some parameters from the PRESET
configuration (for less than frequency) an asterisk appears on the
top-right corner until a save command is executed.
Using <+/-> selector all menus can be accessed in sequence, push <click> to enter edit mode:
<+/-> to setup field
<click> again to confirm changes and exit.
exit without confirmation if no button is pressed after a few seconds time out.
<START UP> menu
These menus are displayed during power up for few seconds.
<STATUS> menu
This is the first menu displayed after power up.
<PRESET> menu
This menu can be entered by scrolling selector
The other 8 configuration presets are user programmable thru the infrared and the PC interface (using
the programmer UPK 300/UPK
We provide the device with some preset configurations specifically designed for certain types of
microphone or applications (it’s possible to change these presets in any time using the TX manager).
All parameters can be “left unchanged”, “changed” or “changed and lock”, allowing a very flexible way
to pre-program MTP41S configuration.

In this menu current channel/group and frequencies can be setup.
The name of the group is shown on the top right of the display.
Sync group is a quick self-settable channel synchronized by receiver
(with SYNC group, on the top right of the display is shown the name
of the synchronized receiver).
Use the selector to change values (<+/->) and <click> to confirm.
Using quick channel setup buttons (<CH>), it is possible to enter
quickly in the tuning menu. Note that the menu has a different
layout (see the side image)
The sensitivity of the audio input is settable between “AF Gain”
(measured in dB) or “AF Level” (measured in dBu).
To help proper audio gain setting, an audio bar is supplied (with
maximum peak indicator) indicating the headroom to audio peak
(0 dB , nominal deviation 40KHz). Set the gain, with the maximum
input signal, avoiding the peak on the audio bar.
TRY TO SETUP TO HAVE A MAX PEAK HOLD BAR CLOSE TO -6dB.
Using quick gain setup buttons (<GAIN>), it is possible to enter
quickly in the audio gain menu. Note that the menu has a different
layout (see the side image)
The second <AUDIO> menu allows to set:
- Audio phase: 0° or 180°
Note: Since common "2-wires + bias" microphones invert the
phase, when the MIC mode of the transmitter is set to “2wires+
bias”, the phase is automatically inverted and so the complete
system (MTP4x+MIC) has 0° phase (an asterisk appear on the
display near the phase to indicate that the phase was inverted).
- High Pass Filter: applies different audio HP filter: Flat/ 60Hz/
80Hz/ 120Hz/ 170Hz/ 250Hz/ 400Hz.
The third <AUDIO> menu allows to set:
-Noise reduction:
ENR: designed for maximum noise reduction
ENC: designed for maximum audio fidelity (use this in
case of special vocal application or to remote
instruments)
-Limiter: if is set “On”, an input audio signal above the peak
threshold (up to 30 dB above peak) is not cut but attenuate,
without lost quality. The limiter acts as a variable attenuator
(thanks to the feedback system), maintaining a distortion
<3%.
When the limiter intervene, the front led turns blue.
If this parameter is set “Off”, the limiter is disable.
<TUNING> menu
This menu can be entered by scrolling selector or using quick channel setup buttons (<ch>).
<AUDIO> menu
In the AUDIO menu are shown all the audio parameters (this menu can be entered by pushing <+/->).
