WARNING NOTICE TO USER!
The Radial JDX 500 is not a load box. This means that if you are using it with a guitar
amplifi er it must be connected to a speaker cabinet or some type of load box. Failure
to do so could result in damaging the JDX and your amplifi er which of course would not
be covered under warranty. Always ensure you have proper cables and connections
have been checked. We recommend using high quality 12 gauge speaker cables.
Because the JDX 500 can also be used as a direct input from a guitar, we have
instituted a slow fl ashing LED to let you know when you are in this mode. This safety
measure reminds you that you should not connect a guitar amplifi er output to the JDX
when in guitar mode as this may damage the JDX.
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 is 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.
