4 Antenna Combiner for IVM4500


SPC4500 is an active wide-band UHF antenna combiner for connecting up to four SST4500 IEM transmitters to create large multichannel systems. It works in an ultra wide frequency range from 500 to 865 MHz. The combiner features a green/orange/red status indicator LED for full control of systems status. Any unused antenna output is automatically terminated to prevent unwanted radio interference noise.

The SPC4500 comes in a rugged half-rack metal housing and works with all passive AKG transmitter antennas.
