Designed to be the hub of a wired intercom system, the compact MS741 Master Loudspeaker Station satisfies common installation and operational demands.

The MS741 Master Loudspeaker Station has two independent intercom circuits, A and B, which can be addressed separately or together by the operator. Each circuit 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.

Designed to be the hub of a wired intercom system, the new compact MS745 is 1U high and is compatible with existing Tecpro products. It offers two independent intercom circuits which can be addressed separately or together by the operator and has the same universal power supply as the flagship MS741 Master Station. The feature set has been carefully chosen to suit the majority of touring and fixed installation applications.

The MS745 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 will be required, the MS741 Master Station and ME742 Master Station Extender unit should be considered.

More information...

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.

Currently in development, the TW403 connects to a Tecpro wired intercom circuit, and acts as a bridge between the wired and wireless intercoms. While reducing the number of full-duplex beltpacks available to five, since the interface becomes one of the six nodes in the group, it extends communication between the wireless users to all the users available on the wired system.

By using more than one wireless interface and selecting different frequencies, up to three wireless communication groups can be created, for example riggers, floor manager and a lighting crew, each one requiring a separate wireless interface and Tecpro Series 2 channel.

Constructed in an extruded aluminium housing, the interface has connectors for connection to the intercom circuit and for the included external TW413 whip antenna.

Included accessories: TW413 whip antenna, data sheet. Optional accessories: The TW412 dipole antenna can offer increased range and performance. See below for details.

The TW403 is expected to become available in Spring 2010. Contact Technical Support for assistance.
