Radial OX8 and OX8J 8-Channel Mic Splitter
The Radial OX8 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. This makes the Radial OX8 a great choice from small clubs, churches and concert venues alike.
The Radial OX8 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 OX8 splitters for larger systems.
The OX8 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 OX8 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 OX8 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 Radial OX8 comes standard with Radial transformers or may be special ordered with Jensens. Both transformer options feature precision winding and mu-metal outer shield to keep RF and outside electro-magnetic fields from polluting the all-important magnetic bridge. Keep in mind that the audio signal path is bridged passively via the transformer and this is the ‘engine’ that does the work.
The Radial transformer provides a very solid performance from 20hz to 18.5kHz and is ideal for the most demanding live applications and well suited for recording. The Jensen transformer extends from 10Hz to 40kHz making it ‘the ultimate choice’ for ultra-high resolution applications.
During our market research, it was clear that engineers wanted the OX8 to have smallest possible footprint while providing the maximum feature set. To accomplish this task, 25 pin D-Sub connectors were selected as the primary interface. D-Subs have been employed for over a decade by companies such as Tascam and Digidesign. This makes the cables readily accessible and easily replaceable should a failure be encountered in the field. The OX8 employs the Tascam standard 8-channel configuration and pin out.
To accommodate permanent installations, a series of euro-block (Phoenix -style) connectors have also been added. This makes the OX8 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 OX8 rear panel and provide a protective ‘buffer’ in between the more fragile D-subs and the real world.
