Ambient Noise Controller, Volume Controls
Order No. 17.2280
Ambient noise controller, for automatically
matchingthe signal in case of ambient
noise.
The wanted audio signal is held at a fixed
distance to a second audio signal. The
second audiosignal is usually the ambient
noise which normally appears in shopping
centres, hotels, train stations, airports or
restaurants. The supplied noise detector and
a microphone (available at option)monitor
the ambientnoise and the wanted signal
(e.g. announcement or music) is boosted or
attenuated accordingly. Thus, the signal for
announcements or music is, at the set level,
always at a higher volumethan the distract-
ing ambient noise.
• Supplied with noise detector forthe con-
nectionofan electretmicrophone or a
dynamic microphone with XLR jack or
6.3 mm jack
Matching microphones DM-2500,
ECM-302B/WS, ECM-10/SW or
ECM-10/WS are availableatoption.
•Adjustable limiter for setting the low output
level
•Adjustable Q-factor
•Adjustable band fil
ter for measu
ring
(30-15,000 Hz)
• Bypass switchfor deactivating the noise
detector
•Phantom power can be switched on
additionally via noise detector
•LED display for output level and clipping
• 24 V emergency power supply
