INTRODUCTION

“MTP40S is an extremely small and light pocket transmitter especially designed for professional
wireless microphone applications”

Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector.

MTP40S benefits also of the latest Wisycom RF technology along with an enhanced robustness
against noise and inter-modulation.

CLICK

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 (MTP40S),

- 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: +00 dB) and high pass filter (i.e. HP:60 Hz)

- “RF 100” or RF 50” or “RF 10” on top right if RF transmission

is active respectively at 100mW or 50mW or 10mW

- On left, battery bar is displayed

MTP40S 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) a star appears on the top­right corner until a save command is executed.

Using <+/-> selector all menus can be accessed in sequence, push <click> to enter edit mode (in the
left side of the display appear the word EDIT and the parameter start blinking):

<+/-> 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, or pushing at the same time both quick channel
setup buttons (<ch> & <gain>).

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 MTP40S 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-Wisy: designed for maximum noise reduction
 ENC-Wisy: 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

This menu can be entered by scrolling selector or using quick gain setup buttons (<gain>).

RF power can be setup to 10mW, 20mW, 50mW or 100mW
(depending on the Power profile).
Use the Battery menu to select the type of battery used.
MTP40S support Alkaline/NiMH/Lithium battery type.
Use the selector to change values (<+/->) and <click> to confirm.

Led Light allows to change the brightness of the front led (0÷16) .

Led Mode:

- None: allows to disable modulation peak LED on front led

(the red light)

- ModPeak: allows to enable modulation peak LED on front led

(become RED when audio get close to saturation when
the limiter is not enable)

- PTT: allows to enable RED color on front led when PTT button

is pushed.

Mode: Following Mic mode can be setup (for LEMO option)

-2 wires: (PTT is possible) for external audio input

-2 wires + bias: (PTT is possible) for most 2 wires MIC

-3 wires: (no PTT) for most 3 wires MIC

-2 wires & pha: to connect a wired mic thru a 48V adapter

(PHA48)

-2 wires+bias & pha: Allow to connect a ‘2 wires + bias’ MIC or a ‘2

wires & phantom’ MIC (with PHA48)

PTT setting defines how and what information the transmitter has to send in normal use or when
the PTT button is pushed.

- Disable: when the PTT button is pushed, nothing happen. (the transmitter sends AF+Tone

squelch)

- Normal: when the PTT button is pushed, the transmitter send a different RF signal. According to

the receiver configuration the audio can be enabled/disable on LINE (and/or COM).

- Muting: the transmitter doesn’t send the audio. The voice is cut, it doesn’t enter to the

microphone

- No Data: the transmitter sends neither tone squelch nor battery data.

Use the selector to change values (<+/->) and <click> to confirm.

In this menu it’s possible to see the frequency set on the device

and the name of the transmitter.

It’s possible to enter on this menu also pressing at the same time

the CH/GAIN buttons ( B + C )
