panion receiver as part of a high reliability
wireless radio frequency transmission
system. The portable transmitter shall
operate within a RF frequency range of
516 – 865 MHz in 20 fixed frequency
banks or 6 user banks with a maximum
of 64 presets with a switching bandwidth
of maximum 75 MHz tunable in 25 kHz
steps; carrier frequencies shall be maxi-
mum 3000. Nominal/peak deviation shall
be ±24 kHz/±48 kHz. Frequency stability
shall be ±15 ppm. RF output power shall
be selectable at 10 mW (Low), 30 mW
(Standard), 50mW (High) and 100 mW
(Maximum, XP version only). A compan-
der feature shall be included and shall be
Sennheiser HDX system with pilot-tone

This lightweight yet extremely rugged bodypack transmitter is a delight
for both the musician and the audience. With an AF frequency response
of 18 to 20,000 Hz, it transmits even the sound of a bass guitar with rich
fundamentals. Three RF output powers (four inclusive the US version)
provide longer transmission ranges or more channels per frequency ran-
ge. The rechargeable batteries of the SK 2000 (optional) can be charged
right in the unit using the external charging contacts.
