Tecpro

Tecpro는 '두개의 와이어' 혹은, 많은 사람들이 같은 통신에 참여할 수 있게 해주는 '파티라인', '링' 시스템이라고 알려져 있습니다. 모든 사용자는 전화기 시스템처럼 일제히 말할 수 있는 동시에 같은 서킷에서 다른 사용자들의 말을 들을 수 있는 전방향의 대화가 가능하도록 합니다. Tecpro 시스템의 주요 어플리케이션은 극장, 컨퍼런스, 라이브 공연 그리고 방송 시스팀에서 사용됩니다.

MS745

Original Tecpro master stations offered a creditable 650mA per circuit - enough to drive sixteen of our BP511 beltpacks. The new MS745 master station supplies 1.25A per circuit - almost doubling the drive current.

The MS745 Master Headset Station is ideal for applications where a simple two circuit intercom system is required without the need for future expansion. If more facilities and intercom circuits may be required, the MS741 Master Loudspeaker Station and ME742 Master Loudspeaker Station Extender unit should be considered.

Each intercom circuit has its own individual power supply with short-circuit protection. All protection is electronic and automatic and no resetting is necessary following removal of a fault condition.The Master Headset Station can be operated world-wide without the need to change AC power supply settings.

Each intercom circuit (A and B) can power up to 25 Tecpro BP511 beltpacks. Circuit B may be linked to circuit A to form a single circuit supporting up to 50 beltpacks.

The operator listens and talks to other users via a headset and may speak to circuit A, B, or both by pressing the associated circuit select buttons. Both circuits remain independent and cannot communicate with each other (unless linked). External audio sources such as programme feeds, show relay or paging announcements can be mixed to either or both intercom circuits. The amount of auxiliary signal added is set using the 'Aux Level' control.

To keep communications circuits clear of background noise and chatter, due to microphones being left open unnecessarily, Series 2 Tecpro beltpack and user stations can be silenced remotely from the MS745 Master Headset Station by use of the 'Remote Mic Kill' facility.*

*Tecpro Series 2 products are backwards compatible with first generation designs with the exception of 'Remote Mic Kill' which applies to Series 2 products only.
