Radial Engineering 8OX-JENSEN
8-Channel Mic/Line Splitter Jensen

The Radial 8ox is a passive 8-channel splitter that enables mic signals to be distributed to various destinations without introducing noise or artifact. To simplify connectivity it is equipped with various connectors making it adaptable for live sound, recording and broadcast. The single space 19" rackmount design is compact yet easily expandable by applying a modular approach. It is ideal for small clubs, churches, concert venues, and more.
 
The Radial 8ox is a full-function mic splitter that has been designed to accommodate remote recording, broadcast and live sound installations. It may be used alone or combined with other 8ox splitters for larger systems. The front panel provides quick access to the XLR connectors for on-the-fly hookup. High-performance glass filled nylon XLRs with oversized nickel-silver contact pins assure long life and excellent connectivity. Next to each input connector is a ground lift switch that lifts pin-1 on the auxiliary output to reduce noise caused by ground loops. A -36dB pad provides an effective means to interface line level devices by providing a preventive measure against transformer overload.

As with all Radial products, the 8ox is designed to withstand the abuse of professional touring. A 12 gauge front panel and welded 14 gauge steel frame provide a rigid platform to ensure the internal electronics are protected.

One of the key attributes built-in to the Radial 8ox is a noise eliminating RF filter on each channel. Noise is further reduced by shortening the input distance in front of the transformer, effectively eliminating the antenna. A dual sided military spec printed surface board increases solder flow to both sides to improve circuit connectivity and part bonding. This is particularly beneficial for large parts such as the transformers. The Jensen transformer extends from 10Hz to 40kHz making it the ultimate choice for ultra-high resolution applications.

To accommodate permanent installations, a series of euro-block (Phoenix -style) connectors have also been added. This makes the 8ox simple to integrate into a sound system such as a church or performance venue while providing easy strip & insert connectivity for field servicing. (note – wire end terminal blocks are sold separately). For concert touring, a custom break-out panel would normally be added that would feature XLR or multipin connectors mounted on a steel plate. This would then be wired to the 8ox rear panel and provide a protective ‘buffer’ in between the more fragile D-subs and the real world.
