MTK952 User Manual rev.06   1  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)s 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.

MTK952 User Manual rev.06   9  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).
MTK952 User Manual rev.06    10 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 3rd 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.  EXT ATT compens. For future uses.

MTK952 User Manual rev.06   11  Equalizer This menu allows to  of adjusting the gain between frequency components (bass, mid and treble)  within the audio signal. There are 4 windows in cascade: bass windows: allows to change gain and frequency of low frequencies mid windows: allows to change gain and frequency of middle frequencies treble windows: allows to change gain and frequency of high frequencies eq windows: allows to save the equalization parameter or exit without save Each window shows the following information:   ❶ windows name ❷parameter to set (gain or frequency) ❸ graphic equalizer: frequency on horizontal axis, gain on the vertical axis ❼ HP filter set in the mode menu  ❻ LP filter set in the mode menu ❺ set frequency ❹ set gain  For each window it is showed the graphic equalizer which help to see the set parameters. Push the rotatory knob to change the parameter between gain and frequency (the respective letter  G or Fr is highlighted during the setting phase) and            rotate it to change the value of the parameter. The set value is showed on the bottom of the windows (see points  ❹ and ❺ on the above image).  Push the lower membrane button to go on the next windows. The following table recaps the settable values on the 3 windows:  Fr (frequency) G (gain) Q (Q factor) bass 40/80/160 Hz -12÷12dB (1dB step) - mid 1.5/2.2/2.8kHz 0.7/1.0/2.0 treble 5/7/10kHz - NOTE: High Q factor means narrow bandwidth. Low Q factor means wide bandwidth.

MTK952 User Manual rev.06   13  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).        Example of configurations:  iso-frequency  areas       MTK952N Master conf.
