1Ch Microphone splitter with 3 direct / 1 isolated output. Wireworks T-Series Transformer Isolated Microphone Splitters, featuring genuine Jensen Transformers, are compact, uniquely packaged, and easy to use. T-Series splitters are meant to be used wherever a single microphone signal must be fed to more than one input. Each unit provides one channel of microphone splitting, and with T-Series' unique packaging, up to 10 splitters may be rack mounted in one 5.25 space. T-Series Microphone Splitters, like all other Wireworks Microphone splitting products, utilize only the highest quality transformers, providing uncompromising performance in all applications. Each microphone splitter features a 1:1, 1:1:1, or 1:1:1:1 turns ratio bridging transformer with a single primary and one, two, or three secondary windings. Transformers also maintain separate faraday shields and reject common mode noise caused by the voltage differences between the chassis of the multiple mixers. Phantom power can be provided by the mixer which terminates the microphone directly. The splitter is equipped with two switches, one to lift the ground to the isolated output(s) and the other to lift the chassis ground from the direct output for optimum performance. T-Series splitters are ideally suited for applications where the microphone lines have not been incorporated into a large Multicable system, but where quality, reliability, and performance are essential.
