MTK952 User Manual Dual Transmitter Mono - Stereo - Intercom Modulation SN: ________________ rev.06 (ref. FW 2.0) Date: 10 April 2015 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 2 SAFETY INSTRUCTION  Read this safety instruction and the manual first  Follow all instructions and information.  Do not lose this manual.  Do not use this apparatus under the rain or near the water.  Do not install the apparatus near heaters or in hot environments, do not use outside the operating temperature range.  Mount the apparatus as indicated in the instruction, do not block side grids for air ventilation  ATTENTION: supply the apparatus with a correct mains voltage and with the ground connection. Check the power cord integrity.  The power cord must be protected from damage  Do not install the apparatus near heaters or in hot environments, do not use outside the operating temperature range.  Do not open the apparatus, only qualified service technician are enabled to operate on it. The apparatus needs servicing when it is not properly working or is damaged by liquids, moisture or other objects are fallen in the apparatus.  Use only accessories or replacement parts authorized or specified by the manufacturer.  Clean the apparatus only with dry cloths, do not use liquids.  The ON/OFF is a double pole circuit breaker, but to ensure the complete disconnection of the apparatus, disconnect the power cord.  Report the serial number and the purchasing date in front of the manual. It is needed to have proper replacement parts or accessories from the manufacturer.  When replacement parts are needed, use only replacement parts authorized from the manufacturer. Substitution with not authorized parts could result in electric shock, hazards or fire.  Keep attention on all the labels with warnings or hazards on the apparatus. WARNING! The apparatus is intended for professional use; anyway the manufacturer alerts the user that the headphone output power of the apparatus could exceed the level of 85 dB(A) of sound pressure level and this could be dangerous for the hearings. Do not use the headphone with high power level or for long time. Reduce the power or suspend the hearing in case of any kind of hearing problem. MTK952 User Manual rev.06 3 QUICK START INSTRUCTION 1. Connect to the power outlet using the supplied power cable (see rear panel: connector 1) 2. Attach the antennas to the antenna out BNC connections (N connectors for MTK952N) (see rear panel: connectors 8 and 13) 3. Connect the audio sources to the relative audio input connectors (see rear rear panel: connectors 7 for digital audio sources, connectors 9÷12 for analog audio sources) NOTE: the cascade configuration allows to use the same analog audio input for more transmitter 4. Power on the MTK952 5. Switch off the RF output: a. While the MTK952 is powering on and the progress bar appears, push the 3 rd button at the bottom (see indication “OFF” on the display) b. At the end of MTK952 power on, push the lower button on the right of the displays 6. Enter in the MAIN>Audio source menu and a. configure the input parameter between digital and analog (according to the audio source connected at point 3) b. configure the AF level meter parameter as modulation c. if digital audio source:  leave audio gain left and right parameters to 0dB and adjust the audio level with the mixer  if need change the audio gain left and right parameters d. if analog audio source:  leave audio gain left and right parameters to 0dB and adjust Max audio level parameter. NOTE: this parameters is unique for both the channels (right and left)  if need change the audio gain left and right parameters NOTE: adjust the audio level (thru the mixer and/or Max audio level and/or the audio gain left and right parameters) so that, for the maximum input signal level, the AF level bars show the MAXIMUM NUMBERS OF GREEN LED INDICATORS AND NO YELLOW/RED CLIP LED INDICATORS the MOD. (modulation) b…
