Radial OX8-j Jensen

The Radial OX8-j Jensen is a Passive 3-Way, 8-channel microphone signal splitter, featuring premium Jensen isolation transformers, D-sub / DB25 connectors, XLR, and Euro-Block parallel inputs, together with direct and isolated outputs. Legendary Radial quality and dependability result in some of the best mic-splitters available.

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

The simplicity of a passive design
The OX8's audio circuit follows the time-proven success of Radial's snake systems: it is passive. Now you may ask why passive? The simple answer comes down to control... or more precisely 'who' or 'what' is in control of both the level and the audio quality.

Consider this: If the mic splitter is active, it in other words amplifies the signal. It therefore will replace the mic preamp of your mixing console. This poses a question regarding the quality of the preamp being used... are you sure you want to replace the mic preamp in your $100,000 mixer with one built into a snake? How much are you willing to pay for this second preamp?

What about control? In a live stage environment, where you may have 3 mixing consoles connected at the same time, who should be in charge of the trim control that sets the level coming from the mics? In an active system (and digital system for that matter), you only get one control point for setting the trim while in a passive design, because the microphone feeds each console on its own, you can adjust the input level as needed without interacting with the others. That's the beauty of a transformer. Each engineer can adjust the mic sensitivity to suit. Just imagine if the front of house mixer was in charge of the trim and decided to increase the gain on the lead vocal while the monitor engineer already had the volume up to maximum in the in-ear monitors. Who will lose their job when the lead singer's ears are accidentally blown out?

The Radial OX8 is passive. Simple no headaches literally! Transformer isolation also eliminates buzz & hum caused by ground loops. This means you can be up and running quicker. And in pro touring, getting set up quickly without noise is critical.

What is the difference between Radial mic splitters and others?
Top professionals specify Radial because they depend on a product that is durable and will not fail. Radial uses the very best components to ensure fail-safe use. Others can save you money by being cheaper, but will likely not deliver the same level of quality or performance. Check the specs. If they are not complete, then you will likely end up being surprised.

solid and simple passive splitters October 31, 2011
Reviewer: Morten Brekke Stensland from Oslo, Oslo Norway  
If you need to split signals for recording or for the monitor consoles these radial-boxes do the job. The Jensen-transformers on the isolated-outputs means that you dont need to worry much about distorting the signals on the iso-outs. Still Radial has added a 30-db pad on the iso-out, which comes handy when you dont have pads on your preamp inputs.

I have 4 of these installed in a rack. This gives me 32 channels of split in just 4 rack-spaces. I have output connectors on lk-connectors on a panel in the back of the rack, so that I dont have to plug in and out of the d-sub connectors every time I use the splits. I just hate dealing with d-sub connectors all the time, I only like d-sub for fixed installations, not for everyday plugging. Perphaps Radial could have made a box with larger track-counts and some other multipin-contacts for the output?

Top End Gear November 2, 2010
Reviewer: Anonymous Person  
This is an outstanding splitter with quality to rival anything out there.  Nice size makes it easy to fit in any rack system.  All in all I personally think this is one of the best systems out there for three way mic splits.
