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.

ME742

When the ME742 is combined with the master station, the ME742 extender unit adds an extra two channels, C and D. These are technically identical to A and B and may be used independently or linked as required. In total, between 1 and 4 intercom circuits may be configured.

As events become more complex, two communication circuits may not be enough. Interfacing the ME742 Master Loudspeaker Station Extender unit with the MS741 Master Loudspeaker Station creates an additional two circuits, C and D, technically identical to A and B. Between 1 and 4 intercom circuits may be configured. 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 Loudspeaker Station Extender can be operated world-wide without the need to change AC power supply settings.

The 'Override' function triggers Tecpro LS200 or LS300 loudspeakers stations to default to pre-set audio levels, independent of the loudspeaker's current volume control setting. The 'Override' button is located on the MS741 Master Loudspeaker Station.

'Announce' mode allows paging to an external PA system directly from the ME742 Master Loudspeaker Station Extender by routing the talk-back mic signal (derived from the MS741 Master Loudspeaker Station) to a dedicated output on the rear panel. The 'Announce' function is independent and separate from the similar function on the Master Loudspeaker Station. This mode can also be triggered externally.

To keep communications clear of background noise and chatter, all Series 2 Tecpro beltpack and user stations on circuits C and D can be silenced remotely from the MS741 Master Loudspeaker Station by the 'Remote Mic Kill' facility*.

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