The Radial Engineering OX8 is a high-performance 8-channel microphone splitter that lets you send a microphone signal to as many as three consoles at the same time. Each channel is configured with a balanced input, a direct out which also serves as a return path for 48V phantom power, a thru-put with ground lift switch and a transformer isolated output.

The OX8 is particularly well suited for live recording by delivering a transformer isolated audio signal path to the recording system while providing direct feeds to the front of house and monitor consoles. Transformer isolation eliminates hum and buzz cause by ground loops for ultra quiet results.
For maximum flexibility, several connector options are available. Inputs may be accessed via the front panel, using standard XLRs, or the rear panel, with a choice of either 25 pin D-subs (wired to the Tascam standard) or Euro screw-down terminal connectors (Note: Wire-end terminal blocks are sold separately). Outputs include D-subs and Euro connectors, which are also located on the rear panel. These make it easy to connect to popular multi-track recording systems while providing easy termination for permanent installations.

Although primarily designed for mic signals, the OX8 is equipped with a -36dB pad to accommodate line level sources, making the OX8 highly adaptable for all types of signal splitting. Several connector options are available to enhance flexibility. Inputs may be accessed via the front panel using standard XLRs, or via the rear panel with a choice of either 25 pin D-subs wired to the ProTools standard or screw-down Phoenix/Euro terminals which are commonly used in permanent installations.

Because the OX8 is 100% passive, it does not require any power whatsoever to make it work. You simply plug in and the transformers do all the work. The OX8 comes standard with Eclipse ET-MS10 mic bridging transformers or may be special ordered with premium transformers for the ultimate purist. Each channel is further advantaged with an ultra-short signal path and built in RF filters to ensure absolute quiet performance even in the most noise-prone environments.

The Radial Engineering OX8 is a professional recording tool that is equally at home in live touring, permanent installations or broadcast.
