能夠提供卓越清晰度體驗的SKM 9000，作為一款世界頂級數字式手持發射機已經做好了迎接任何挑戰的準備。 SKM 9000與革命（evolution）無線系統G3和2000系列的傳聲器極頭完全兼容，其中包括紐曼KK204和KK205傳聲器極頭。三款新推出的極頭——ME 9002、ME 9004和ME 9005——都採用了一種新型的防震設計，以實現性能卓越的低觸碰噪聲，從而具有更低的口噴靈敏度以及固定極化電容傳聲器的聲學透明性。 MD 9235動圈式極頭可以優先選擇作為大聲級現場擴聲系統的使用。 SKM 9000的數字音頻傳輸提供了令人驚異的大動態範圍，並且在與有線傳聲器共同使用的情況下，它也是一種理想的解決方案。沒有乾擾並且沒有壓縮的數字信號傳輸能夠完美地與線纜傳輸的聲音相匹配。可更換的電池單元採用環保式鋰離子技術，在提供所需能量供應的同時，還避免了產品在其使用過程中數以千計的電池消耗。
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).
