Sennheiser Worldwide: EM 1046 MF


General Description
The EM 1046 MF is a large mainframe for housing up to 8 receiver modules. The mainframe features two integral active 1-to-8 antenna splitters. The back panel houses the power supply module, RF input module and AF output module. The Mikroport computer display can be connected via an interface module. Additional antenna splitter modules are available for multiple mainframe systems. 19inch rack mount "ears" supplied.
Features
	The EM 1046 MF mainframe is the heart of the modular Mikroport system. At the front of the mainframe, a maximum of 8 diversity receiver modules can be inserted. At the rear, the RF input module, the AF output module and the power supply module are fitted. Special rear panel components are available for the simple
	connection and monitoring of a number of mainframes. In addition to the module frame, the mainframe includes a mains socket (rear), mains switch, monitor module and an active 1-to-8 antenna splitter. The operating controls at the front are identical for the EM 1046 MF and EM 203 MF and are explained below. The EM 203 MF is the small mainframe for the 1046 system. Up to three diversity receiver modules can be accommodated. In the EM 203 MF, the rear is already completely equipped. An RF input module contains BNC sockets for the two diversity antenna and two passive 1-to-3 antenna splitters for supplying the receiver modules. The EM 203 MF mainframe is not operated with an active RF input module. To achieve the same gain and frequency selectivity as with the large mainframe, an active antenna or an antenna booster should be used. The antenna amplifier must operate selectively within the switching bandwidth of the receiver modules.
