The pocket transmitter SK 6000 is intermodulation-free, which allows operation in an equidistant frequency grid. The transmission concept thereby permits, even in the toughest frequency ranges, maximum spectral efficiency. In short: more channels, maximum transmission performance at all times and hence outstanding signal stability. The legendary Sennheiser Digital Audio Codec (SeDAC) guarantees clear, artifact-free sound and optimum dynamics. In Link Density mode up to 5 links per 1 MHz bandwidth are possible. The SK 6000 is the high-end solution for guitar bass or as a transmitter for the Sennheiser clip-on microphones MKE 1, MKE 2 and MKE 40, headsets HSP 2, HSP 4 and SL Headmic. The magnesium housing combines the benefits of being inconspicuous in size, a robust design and low weight, while offering reliable protection against moisture. The lithium-ion battery pack BA 61 ensures up to 6.5 hours of operation; there is also the option of operation with batteries using the battery set B 61. The transmitter is likewise compatible with the EK 6042 and the EM 9046 in Long Range mode.
