Designed to interface with the MS741 Master Loudspeaker Station this extender unit is not intended for standalone operation. The compact ME742 Master Loudspeaker Station Extender is 1U high and has been developed from the highly successful original Tecpro designs.

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.
