BRIEF DESCRIPTION
MTK952 is a versatile dual transmitter capable of working in a huge UHF bandwidth and of
generating any kind of narrow-band modulations, with very high quality and low spurious
emissions.
Main features:
330 MHz Bandwidth (470 MHz 800 MHz)
2400 user-defined frequencies (40 group by 60 freq.)
Stereo, mono, intercom audio modulation
Output power up to 2 Watt (/W option)
Analogue & digital input (AES3)
Redundant power supply 230/110 Vac & 12 VDC
DSP audio processing (40bit floating point / 2Gflops) with multi-companding
Direct Digital Synthesis (DDS) of signal for the highest flexibility and quality (> 70 dB
stereo separation) SWR (Stationary Wave Ratio) sensing on antenna outputs
Above a schematic with the functional diagram of one transmitter of MTK952.
MTK952 use extreme technologies like:
Direct Digital Synthesizer (DDS)
DDS is a type of frequency synthesizer used for creating arbitrary waveforms from a single,
fixed-frequency reference clock. A DDS has many advantages over its analog counterpart, the
phase-locked loop (PLL), including much better frequency agility, improved phase noise, and
precise control of the output phase across frequency switching transitions.
The Direct Digital Synthesis (DDS) technology can generate virtually any kind of modulation
while keeping an absolute phase accuracy.
Double conversion stage
Using a double conversion and saw filter at IFs (intermediate frequencies) we can achieve a
very low spurious emission and a great bandwidth agility (330 MHz).
Intermodulation cancelling power amplifiers
PA module (power amplifiers) is designed with an exclusive circuitry that reduce the
intermodulation generated by external carriers using a wideband phase cancelling design.
Digital audio with Shark™ DSP 40bit floating point & 2 Gflops power from Analog Device
A very powerful Analog Design Shark DSP processor manages the audio with very low delay
(< 1 ms) and emulates by software all companding and pre-emphasis effects.

MAIN MENU
The first item on the menu tree is “MAIN”.
Ch-Gr
The CHANNEL-GROUP item enables the user to edit channel, channel group and frequency of the
selected item. Change, rotating the knob, the channel or the group of channels and confirm or exit
with the buttons. To edit the frequency of selected channel, press the middle button and change it
with the knob. Press the knob to move between MHz and KHz. Confirm or exit with the buttons.
As shown in the above picture, the display area has 3 rows with:
1) Channel number (0 to 60) and Channel frequency (in 5kHz step)
2) Number (1 to 40) and Group name (8 char.)
3) Group description (30 char.)
The MTK952 has 40 groups of 60 channels each. Normally this is too much for wireless
microphones applications.
Connecting with computer with WISYCOM Rack MANAGER software, it is possible to hide single
channels or even complete groups of channels: once hidden those items are not shown anymore
on the channels or groups selection. To show channels or groups hidden use again the WISYCOM
Rack MANAGER software.
Using this software it is also possible to lock channels or groups. When a channel is locked, it is not
possible to change the frequency from the front panel of the transmitter. Locking a group means
that all channels are locked. When a channel or a group are locked, at the left of the group name in
the Chan-Group menu will appear a lock icon . When the lock picture is shown, the central
button is not displayed, thus changing frequency is not possible.
Group name
The second item on the Main menu is GROUP NAME; with this function is possible to assign or
change a name to a group of channel. This short name (8 character) is displayed at the right of the
group number in the main display view. First chose the group and then press the knob. You will be
able to edit any character of the group name rotating the knob. Push the knob to edit the next
character. Confirm or exit with the buttons.
NOTE: when the Group name is SYNC (see synchronization) it is not possible to change it.
Mode
The MODE menu allows to assign a Mode setting at the transmitter. Rotating the knob it is possible
to change current mode among the modes available (for more detail see MODE menu).

TX on air at startup
This menu allows to decide if turn ON or turn OFF the RF power of the transmitter while the
MTK952 is powering on.
If set to No: while the MTK952 is powering on, the RF output remains mute. The Status Screen on
the display shows “TX OFF “ and the set Group, Channel and frequency.
NOTE: When the RF power of the transmitter is OFF, all the led and the bars remain turned off.
Pushing the rotatory knob (at the right of the display) it is possible to activate the led and bars
(keeping the RF power OFF) and enter on the menu.
In order to activate the RF output press the 3
rd
button
at the bottom (see indication “ON” on the display).
If set to Yes: during the MTK952 power on, the
progress bar appears for 10 seconds.
During this interval (10 sec.) it is possible to switch off
the RF output. If no button is pushed, at the end of the
timer the RF output is enabled automatically.
TX power
This menu allows to set the power of the transmitter. Rotating the knob it is possible to change
current TX power setting among 10/20/50/100/200 mW (2W only for MTK952 with 2W option).
Push the SAVE button to confirm. In the same screen is showed the reflected power and the SWR
(Stationary Wave Ratio) sensing on antenna outputs.
The set TX power and the measured SWR are always
showed at the bottom of the display.

TX configuration (only for MTK952N with option MS)
This parameter permits to use the transmitter in Master or Slave configuration.
When the MTK952N is in Master configuration, the signal is transmitted as a normal MTK952N
(without MS option) but at the same time, the signal is sent also in the M-S I/O BNC connector at
0dBm (without amplification).
When the MTK952N is in Slave configuration, everything that is before the power stage is excluded
and the device take as input the signal that enter in the M-S I/O BNC connector, amplifies the
signal (at the power set on the MTK952N-Slave) and transmits it.
MTK952N is able to detect a signal in the range -6dBm ÷ +6dBm (than the 0dBm sent from the
MTK952 Master).

The second item on the menu tree is “MODE”. It allows to manage several modes.
Each mode is a setup saved in an external memory that allows to customized the transmission
changing some parameters of the DSP. There are 2 types of modes:
PRESET mode: it allows to change only some parameters (the other are fixed). See
compatibility table at the end of the manual for more detail
USER mode: it allows to change all the parameters. Currently 8 USER modes are available
The menu Select for edit allows to select the MODE to edit. Push the knob to select the mode and
push the button LOAD to load the previously saved parameters. It is possible to change the

Synchronization
The SYNC function is useful to tune a transmitter on the same frequency of the receiver via the IR
interface.
Enable the IRDA on the receiver and place the IR windows of the receiver in front of the
IR interface of the transmitter as indicate in the below image.
Press the SYNC button on the transmitter: the following message is showed on
both the displays
Using the membrane buttons of the desired transmitter (TX1 or TX2) select:
TX->RX to set the receiver at the same frequency of the transmitter:
the transmitter will send to the receiver some parameters (frequency, channel,
group and transmitter’s name) and after synchronization, the receiver shows the
name of the transmitter
RX->TX to set the transmitter at the same frequency of the receiver:
the receiver will send to the transmitter some parameters (frequency, channel,
group and receiver’s name) and after synchronization, the transmitter shows the
name of the receiver (ex. SINGER_1)
If the operation is not possible, (i.e. the frequency range of the transmitter is not compatible with
the frequency of the receiver or vice versa), the display shows an error message.
If the synchronization is successful, the display of the devices shows number of channel and group
or SYNC channel according to the frequency plan memorized on the Wisycom product:
