EM 1046

Article No. 25321

Key Features
  • Modular multi-channel receiver system for demanding musical and broadcast applications
  • Large mainframe houses up to 8 true diversity receiver modules
  • Small mainframe houses up to 3 true diversity receiver modules
  • Several mainframes can be daisy-chained

General Description

The EM 1046 receiver module is at the heart of any 5000 series receiver system. All functions can be quickly checked via an alphanumeric multi-function display panel, LED bargraphs and individual LEDs. Due to the menu-assisted operation, parameters can quickly and easily be modified.

Accessories

Receiver module

 EM 1046 RX-L

 03246

 Receiver module, frequency range 450 - 790 MHz

Receiver module

 EM 1046 RX-H

 03247

 Receiver module, frequency range 760 - 960 MHz MHz

Output modul

 EM 1046 AO-X

 03249

 The EM 1046 AO-X output module is the interface to the subsequent audio
equipment. In systems with several mainframes, the channels of any mainframe
can be monitored individually via the monitor bus.

Balancing card

 EM 1046 AO-Z

 03597

 By using the EM 1046 AO-Z balancing card, the 25-pin sub-D AF output of the
AO-X output module becomes a fully functional, transformer balanced second
output.

Antenna splitter

 EM 1046 ASP 212

 04341

 The three EM 1046 ASP antenna splitter modules serve to supply several
mainframes with the signals of only two antenna. With an EM 1046 ASP 212, a
16-channel system can be operated with only one pair of antenna.

Blanking plate

 EM 1046 CC-10

 03516

 The EM 1046 CC 10 closes off unused spaces at the front of the EM 1046 MF and
EM 203 MF mainframes.

Blanking plate

 EM 1046 CC-12

 03517

 The EM 1046 CC 12 is used for closing off spaces at the rear
of the EM 1046 MF.
