RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH
HAS BEEN DESIGNED TO GUARANTEE RELIABILITY AND HIGH
PERFORMANCE.
BM 3022 is a pre-amplified desk-top paging microphone with an electret capsule.
Its output audio signal level (balanced and adjustable through a trimmer) allows
its connection to “line” inputs of mixer-amplifiers, even for long distances
(up to 1 km / c. 3300 ft) through CAT5 cable.
Every paging microphone has an automatic gain control (AGC), a compressor /
limiter that (if enabled) normalizes the microphone signal level, regardless of the
voice intensity.
Up to 30 BM 3022 paging microphones can be linked in series (‘daisy-chain’, in
a single line) and used either in mixing (more microphones activated at the same
time) or in interlocking (only a single microphone activated at a time).
One or more paging microphones can have priority and be activated at any time,
disabling all other paging microphones without priority.
When activating a microphone, the announcement can be preceded by a chime.
A
RCF
AC AD2405
adapter (24 V dc) is included. This can be used a power
supply unit for max. 4 BM 3022 paging microphones.
Before connecting each BM 3022 paging microphone, it is necessary to set its
internal dip-switches (according to the chosen operation and options).
Unscrew the 6 fixing screws of the rear cover to open the paging microphone
and access the 8 dip-switches.
