The EK 3241 true diversity receiver
The EK 3241 is a miniature true diversity receiver designed
for use with digital ENG camcorders. It can be inserted into
the slot-in facility of e.g. Ikegami, Panasonic, Sony or
Thomson camcorders without any additional connecting
cables being required. The GA 3041-C slot-in housing is

without a slot-in facility. Together with a suitable
Sennheiser bodypack or hand-held transmitter, a highly
reliable radio link can be set up.
The EK 3241 receiver has the following features:
y Extremely compact and robust all-metal housing
y Special protection against the ingress of moisture and
therefore suitable for outdoor applications
y Mounting kits available for all current professional
camcorders
y Power supply via camcorder or GA 3041-B battery
adapter
y User-friendly, menu-assisted operation via LC display
y High operational reliability due to true diversity reception
y HiDyn plus™ noise reduction system
y Up to 32 preset receiving frequencies
y 36 MHz switching bandwidth
y Frequencies tunable in steps of 5 kHz
y Signal-to-noise ratio >110 dB
