Description

OX8™ by Radial Engineering is an 8-channel passive microphone splitter in a 19'' rack format, designed to send the outputs of multiple microphones to three different destinations at once. It features an isolated transformer and a "Ground Lift" device to eliminate hum and buzz caused by ground loops.

Main Features:

    
• 8-channel balanced microphone signal splitter
    
• Highest audio quality without distortion
    
• Choice between Jensen or Eclipse transformers
    
• Eliminates hum and buzz caused by ground loops

Microphone Splitter

Radial OX8 is a professional audio device, equally at home on a live stage or in a television broadcast studio. It can split the signal of 8 microphones to multiple destinations simultaneously, all without noise or distortion, eliminating common ground loop noises such as hum or buzz. 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 a "Ground Lift" selector, and a fully transformer-isolated output. The OX8 can be ordered with the renowned Jensen JT-MB-CPC transformers, or, as an alternative, with the more affordable Eclipse ET-MS10. Each channel also benefits from a very short signal path and built-in RF filters that ensure silent performance, even in the most noise-prone environments.

    
• XLR microphone input: Standard 600Ω balanced, input connected in parallel with the rear panel D-Sub.
    
• Channel identification label: area for writing with a wax pencil to immediately identify the channel in the instrument's configuration.
    
• -36db attenuation pad: reduces input sensitivity to properly connect even line signals without distortion.
    
• Ground Lift: Helps eliminate ground loops

Using OX8 to record a live show

The OX8 is ideal for recording live shows. Simply connect the microphones on stage to the OX8 and send their split signal to the recording system and the PA System. The transformers isolate the recording system and eliminate hum and buzz caused by ground loops.

Using OX8 live with a PA System

There's nothing more annoying than the hum and buzz that can come from stage monitors. The OX8 is easily configurable to isolate the FOH mixer and monitor mixer to ensure complete noise elimination. Multiple units can be used for 16 or more channels.

Using OX8 for Live Event Broadcasting

The auxiliary output can feed the monitors, while the isolated output provides the signal to a broadcast truck. The OX8's exceptional sound quality provides a distortion-free feed to the broadcaster, allowing the PA system to operate independently.
