Ground lift
There is a hidden ground lift switch (mini slider) that lets
you lift the ground on the front and rear XLR inputs. As the
Twin-Servo is equipped with an input transformer, you will
likely never need to lift the ground. This should be set in
the upward position. However, a unique situation could arise
where you may incur noise. To lift the ground, you have to
pull the module from your power rack and then move the
slider downwards towards the 15-pin card edge connector.
The ground lift switch does not affect the ¼” guitar input
portion of the Combo jack or the output side of the Twin-
Servo. note that when the ground is lifted, the Twin-Servo
will no longer pass 48V phantom power to your microphone.
Hi-Z input and omniport™
The Twin-Servo has two instrument input options. The
immediately obvious one is on the front panel - as part of the
Neutrik Combo connector. Note that this is a standard hi-Z
¼” instrument input and using a 1/4” TRS connector is not
recommended. The second is via the Omniport™ for those
that are equipped with a Radial 500 series power rack. Both
are connected in parallel but as soon as you engage the
front panel jack, it will automatically switch the rear panel
¼” input off.

Although preventative safety measures have been designed into Radial 500 series
products
we strictly advise against hot-swapping modules
or plugging and
unplugging them when the Workhorse or other 500 series rack are powered on. Hot
swapping can cause connection sparks at the card-edge connector that could send
damaging transients to other equipment. This also greatly reduces the life span of the
contacts. Damage due to hot swapping is not covered under warranty. There are no
user serviceable parts inside.
