The SKM 5200 continues the tradition of the world class SKM 5000. Elements like the award winning design, capsules and the modularity were kept the same. The mechanics, electronis and the user interface were completely redesigned and adapted to the highest requirements of live events.
The SKM 5200 transmitter convinces through robust mechanics, a high frequency agility and a menue driven user interface via the backlit LC-display.
The SKM 5200 is available in three colours: Black, nickel and steel blue (haematite). The handheld transmitter is compatible to all capsules, battery and rechargeable battery compartments of the 5000 series as well as the Neumann microphone heads.
36 MHz switching bandwidth
Jog Dial for easy operation
Tuneable frequencies in 5 kHz steps
3 selectable low cut filter frequencies
Microphone sensitivity adjustable in 1 dB steps
Identification by 8 different coloured markers
8 h operating time for increased safety
It is likely that the noise/static/interference you’re experiencing is being caused by a background RF signal from an external source (ie: broadcast TV or radio stations, other wireless microphones, etc) on the same frequency as your wireless system.
This can be confirmed this by turning off the transmitter and checking the receiver’s display. If there is an RF signal showing on the receiver's display when the transmitter is off that indicates that the receiver is picking up an RF signal from an external source and the receiver is trying to tune this external RF signal which will sound like a broad white noise.
One of the most important steps for proper setup is turning on the receiver first and checking what it sees in the absence of your microphone signal. If the receiver sees an RF signal being generated by an outside source (ie: noise) then you need to retune the system. Depending on which system is being used the exact steps on how to change frequencies will vary. NOTE: When using multiple wireless systems the frequencies need to be co-ordinated together to ensure that they do not interfere with each other.
Once a new frequency is selected get back to the receiver's main display. If there is no RF registering then this new frequency is a "clean" frequency on which to operate.
Keep in mind the RF environment changes from location to location so it is important to always check the receiver for RF levels before turning on the transmitter. It is best practice to always do a frequency scan when using equipment in a new location.
The RF environment is often constantly changing so a frequency scan is really only completely accurate for the exact time that the frequency scan is done (ie: a frequency scan done on Wednesday night could yield different results to a frequency scan done on Sunday morning). Ultimately to ensure a frequency scan is still valid you want to turn on the receivers and leave the microphones off. In this state the receivers should be showing no RF signal to indicate that they are on a clean usable frequency. If you turn on the receivers (with the microphones off) and you are seeing a lot of RF activity that indicates that something in the RF environment has changed and now the frequency which was previously "clean" (and hence usable) is now "dirty" (ie there is an external RF signal on it) and you will need to set the receiver to use a different frequency.
There are no universal rules which govern the use of wireless microphone equipment globally. The rules and regulations regarding which frequencies are allowed for wireless microphones vary widely by country. All Sennheiser products that are sold in the US are congruent to the US rules and regulations as mandated by the FCC.
We can provide information regarding rules and regulations for the US, however because rules and regulations vary from country to country, we cannot advise which frequencies to use outside of the US. Unfortunately there is no universal database that contains all this information.
For information about the rules and regulations for a specific country it is recommended that you directly contact the embassy of the country in question to find out the rules and regulations or contact the Sennheiser subsidiary or partner company in the country in question. You can find contact details for these subsidiaries and partner companies here: (http://en-us.sennheiser.com/service-support-contact-service-partner-worldwide).
In June 2010 the FCC instituted regulations that made it illegal to operate wireless microphones within the 700 MHz frequency range in the United States.
With the transition to digital television TV broadcasters vacated a large section of the UHF spectrum (from 698 to 806 MHz) so the FCC auctioned the 700 MHz band to the highest bidders (including AT&T and Qualcomm) to facilitate the development of wireless broadband Internet service throughout the United States. In addition, the FCC has reserved select frequencies in the 700 MHz band for emergency and national security purposes.
NOTE: The FCC is the Government agency tasked to regulate interstate communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. The FCC sets the guidelines and regulations for all broadcast equipment (including wireless microphones).
