For purchasing information

Zaxcom's MicPlexer 2 is a RF distribution amplifier designed to eliminate noise and distortion while boosting the signal strength of up to four diversity receivers (or more through the use of a splitter). It comes standard with a 35MHz filter window that rejects any unwanted and undesireable RF that is not in the selected range. The unit is easily tuned to any block within the 512-702 MHZ range.

The MicPlexer 2 uses a Switchcraft 761K locking connector, accepts 8 to 18 volts DC, and has a power draw of 90mA at 12 volts. 

Signal is received through the two SMA connectors on the top of the MicPlexer2.  The MicPlexer 2 has 8 SMA connectors on the bottom of the unit: 4 SMA connectors that distribute the signal for antenna 1 and 4 SMA connectors for antenna 2.  Three overload warning LEDs for each antenna input h>elp determine if the MicPlexer 2 is receiving too much RF signal. 

The MicPlexer 2 has a frequency select dial on the front of the unit to change the front end filter on the MicPlexer 2 so that only radio frequencies (RF) in the desired frequency range will be received while undesirable RF is rejected.  Seven standard presets, block 20-26, are included and two custom settings can be set the 35MHz filter to any frequency desired.

When connecting the MicPlexer 2 to receivers, use 50 Ohm low loss coax cable with 50 Ohm SMA connectors and keep the length of the cable as short as possible

N.B.: The MixPlexer 2 contains no power distribution and is not compatible with active antennas.
