소개:
ii3-ESS IP Audio Amplifier module은
Digital Acoustics' paging solution의 중심적인 하드웨어
구성품 입니다..
ii3-ESS는 하나의 8-Ohm speaker를 장착할 수 있으며 병렬로 더 많은 스피커를 장착할
수 있습니다.
With
the addition of a universal 25/70V transformer, a series of speakers can be
powered by a single ii3-ESS, with the quantity of speakers determined by
required output levels.
With a maximum output of 20 watts (8 Ohms), the ii3-ESS
is capable of
driving paging horns with sound pressure levels in excess of 120
db SPL.
For low output applications (<8 watts) the ii3-LESS can use Power of
Ethernet(POE).
For higher output applications (>8 watts) an external power
supply is required.

있습니다.
- 증명된 비용절감(시설 및
유지보수).
- 메인 방송장비없이 네트웍으로
쉽게 확장 전개 할 수 있습니다.
- 인터콤의 추가로 쌍방향
오디오를 전송할 수 있고, 원격지의 오디오 모니터링이
가능합니다.
- 복잡하게 배치된 빌딩을
가진 기업/정부/학교에 가장 적절한 솔루션.
- 쉽게 재난 방송용으로 활용.
Emergency Preparedness
- Provides supplemental reach to overhead paging,
parking, inter-building
and even individual desktop notification.
- Network based system provides integration path to
meet needs and
requirements for notifications to individuals with
disabilities.
- Cost effective means for compliance to Federal
