RF Wireless Systems
| 3000 Series Miniature Receivers
General Description
The new EK 3241 has a switching bandwidth of 36 MHz and frequen-
cies that can be tuned in steps of 5 kHz, making the true-diversity re-
ceiver the perfect partner for Sennheiser’s current transmitter models
SKM 5200 and SK 5212. Frequency-agile products are in greater de-
mand than ever as frequency resources become increa-singly scarce.
We have therefore developed a new tuner module for this true-diver-
sity camera receiver and given the lightweight EK 3241 (200 g/7.05
oz) the capacity for reliable, flexible RF wireless transmission: 32 cus-
tom frequencies have already been programmed within the switching
bandwidth of 36 MHz; in addition the user is free to program and store
another 20 frequencies in steps of 5 kHz into the user bank. The receiv-
er can be easily and intuitively operated with a completely new user
interface, which is similar to that of the SK 5212 bodypack transmit-
ter. For a high operational reliability the EK 3241 displays the battery
status of the transmitter in detail. The receiver is extremely reliable; its
full-metal case is weatherproof and robust.
