MTB40S 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 top-

right corner until a save command is executed.

The other 8 configuration presets are user programmable thru the infrared and the PC interface

(using the programmer UPK 300/UPK

Mini

or the receiver MRK950/MRK960).

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 MTB40S configuration.

80Hz/ 120Hz/ 170Hz/ 250Hz/ 400Hz.

The third <AUDIO> menu allows to set the noise reduction and

setup the limiter:

- MTB40S supports 2 different type of “Companding systems”:

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 intervenes, the front led turns blue.

If this parameter is set “Off”, the limiter is disable.

HOW TO USE WISYCOM TX MANAGER

Wisycom TX Manager allows to read, modify and update the configuration of Wisycom transmitters.

It is necessary to

 connected the programmer UPK300E/UPKMini or the receiver MRK950/MRK960 to the PC

thru USB connection

 run the Wisycom TX Manager

 enable the IRDA communication on the transmitter (see IRDA menu)

NOTE: Wisycom IR Programmer doesn’t work whit MRK950/MRK960 if it is connected to the PC

using an Ethernet cable.

The Wisycom IR Programmer’s window is divided in 4 parts (see the image below):

❶Interface and Device panel contains all the major information of the connected device

❷Current Settings panel shows the current configuration. Thanks the PRESET panel, a previous

saved configuration can be chosen and loaded like current setting.

❸Tuning Frequencies panel allows to handle Groups, Channels and Frequencies

❹Presets panel allows to read, change and save different configurations

10 different configurations are available:

• FACTORY configuration is a locked configuration: no parameter can be changed.

 USER configuration is the only configuration that can be saved using the OLED display (see

<PRESET> menu). Note: It is not possible to change the name of this configuration.

 Other 8 configurations where the user can change both the name and the values of all

parameters.

INTERFACE AND DEVICE PANEL (❶)

At the beginning, the program checks which IR devices are detected and they appears on the

Interface panel.

The user has to select the device and push <connect> button in order to open the communication

with the IR device. A picture on the top in the Interface panel help the user in this selection showing

the type of devices detected. During this process the “IR activity” led blinks to indicate that the

program wait connection’s answer from the IR device.

A successful connection is signaled with the “interface connection” green led, while a failed

connection is signaled with the “communication error” led.

Once a supported device is found, the software automatically reads all the data related to the

remote configuration, as well as the frequencies that are pre-programmed.

Firstly, in order to avoid unwanted operation, no parameters can be changes and the EDIT button,

presents on the bottom of Device panel, is yellow and set to LOCKED state. Pushing the EDIT

button, it becomes grey and sets to UNLOCKED state to indicate that the configurations can be

modified.

In this panel it’s possible to assign a name to the TX (not available for FW v.1.22.0F or previous).

Under this parameter, there is a flag to hide the info menu on the TX (not available for FW v.1.22.0F

or previous)

CURRENT SETTINGS PANEL (❷)

In the Current Settings panel the user can

 with Preset panel → load one of the 10 available configurations

 with other panels → modify all the configuration’s parameters (the same that are

changeable in the OLED display). Each parameter can be locked or hidden clicking the

related lock/hidden button, so the set value cannot be changed next or cannot be visible on

the OLED display.

ATTENTION: All the modifies applied to the Current Settings panel are instantaneous: they are

applied directly to the device and save in its memory but no saved in the preset configuration.

MTB40S User Manual

TUNING FREQUENCIES PANEL (❸)

With the Tuning Frequencies panel the user can select a frequencies group (0÷39) and for each one

execute the following operations:

- modify the Group’s Name

- lock and/or hidden the group

- for each channel (0 ÷59) of the selected group: change the frequency value and the related

status (locked/hidden) (in the center grid frequency)

The SAVE button, at the top of the panel, save

the changes of the group selected (name

group, lock/hidden group).

To change a frequency

value for a specific

channel: double click

on the grid frequency

panel (row=channel’s

number), insert the

new frequency value

and press OK button.

To lock/hide a specific channel,

double click on the grid frequency

panel.

NOTE: keeping pressed the CTRL button on the keyboard and clicking the wanted channel/group

shown on the frequencies grid, the tuning process is executed. It is equivalent to configure the

Tuning in the Current Settings panel but it is easier. The device is re-tuned immediately, so be sure

that the RF power is turned off while changing frequencies with other RF systems in use around you!

MTB40S User Manual

If the currently tuned channel is on the same group that is listed on the grid, the background color of

the related cell (channel) on the grid becomes yellow.

Using the LOAD/SAVE button, at the bottom of the panel, it is possible to load/save the frequencies

for the selected group from/to a .wdf file. To save the frequencies of all the groups click to the

related button above. The legacy option save the channels without the hidden/lock info.

If a parameter is “locked”, it cannot be modified by device menu (using OLED display), while if “don’t

care” propriety is active, when the user load the configuration, the parameter’s value doesn’t

changed.

ATTENTION: Changes are applied only after a “save” action.

NOTE: “a trick” In case of the user have a locked parameter and he is in great need for modify it, he

can save the configuration to USER configuration by OLED (see PRESET menu) and then load the

USER configuration (in this way all the parameters have the lock propriety disable and the user can

modify all the parameters).

FILE MENU

Using a file menu at the top left of the

panel it is possible to load/save all the

configuration values of the device

to/from a .wcf file (Wisycom

Configuration File).

Save a .wcf file

With an infrared device correctly connected, select File->Save User Configuration and select the

destination file.

Load a .wcf file

To load a user configuration select File->Load User Configuration and select a previously saved data

file; a form will be shown, where it's possible to select which data has to be restored and which

skipped. This allow the user to load a particular configuration while keeping other data.
