Using the LX8 to split line levels on stage
Recording live using high quality preamps delivers the
best results. Connect your preamps to the LX8 and split
the signal to the recorder and the PA using the isolation to
eliminate hum & buzz caused by ground loops.
Using the LX8 to feed two different audio systems
Running audio around various environments such as large
venues, multi-function rooms or broadcast facilities can
often lead to noise polluting the audio system. The LX8
eliminates noise problems due to ground loops.

Rear panel chassis screw used
for bonding to technical ground.
The Radial LX8 features an internal grounding option that will be of interest to system engineers when integrating the LX8 into complex
audio-visual systems.
Internal Chassis Ground Lift - All Channels
All connectors are 100% isolated from the steel chassis allowing chassis and signal ground to be kept separate. However, a single
internal switch is provided to connect the pin-1 cable shields to the chassis without modifying the LX8. By default, this switch is factory
set to open or “lifted” allowing the chassis to “float” ungrounded.
Should a specific grounding scheme require the cable shields to be bonded to the chassis simply set this switch to closed (pushed in
position). The switch may be accessed through a small hole in the side of the steel chassis or by removing the top cover. The chassis
ground switch does not effect the isolation provided by the transformer at the ISOLATED output.
On the rear panel a ground screw provides a convenient point to bond the chassis. Use a heavy gauge solid copper wire to bond the
LX8 chassis to your technical ground.
