Beskrivelse
The PA821A antenna combiner is the ulitmate problem solver for products that are dependent on the simultaneous operation of many PSM and wireless microphone routes at a venue. As an active broadband antenna combiner with 8 inputs and output of the PA821A provides a significant improvement in reception quality and up to eight wireless transmitters can be combined in a single antenna. This will reduce intermodulation distortion and also avoid dropouts due to multipath interference.
The PA821A is compatible with the wireless personal monitors Shure PSM 400, PSM 600, PSM 700, PSM 900 and PSM 1000. It can also be used with all other in-ear monitoring transmitter and/ or antenna combiners of the intergrated passive combiner with two inputs and one output can be connected.
Combines up to eight PSM transmitters to a single antenna set for improved RF networking & reduced rack clutter
