Ambient noise controller,
for automatically matching the signal in case of ambient noise.
The wanted audio signal is held at a fixed distance to a second audio signal. The second audio signal 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 ambient noise 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 volume than the distracting ambient noise.
- Supplied with noise detector for connection of an electret microphone or a dynamic microphone with XLR jack or 6.3 mm jack
- Adjustable limiter for setting the low output level
- Adjustable Q-factor
- Adjustable band filter for measuring (30-15,000 Hz)
- Bypass switch for deactivating the noise detector
- Phantom power can be activated as required via noise detector
- LED indication for output level and clipping
- 24 V emergency power supply
Matching microphones DM-2500, ECM-302B/WS, ECM-10/SW or ECM-10/WS are available at option.
