OX8 Specifications

The Radial OX8 is an 8-channel passive microphone splitter. The passive design enables a microphone to feed two or even three consoles at the same time. The transformer coupled output provides isolation to eliminate DC from travelling between mixers, thus reducing noise caused by ground loops. The result is exceptionally low noise in even the most difficult environments. A choice of Jensen or Radial transformer is offered, thus enabling the specifying engineer to select the transformer that best suits performance and budget criteria. The rest of the features are identical.
