Congratulations on your purchase of the Radial Q4 state-variable class-A equalizer.
Although designed to be intuitive and easy to use, we recommend that you take a minute
to read this short manual to make sure you take full advantage of the many features
that are built in. Should you fi nd yourself asking a question that is not addressed, we
invite you to view the Q4 FAQ page on our web site. This is where we post the latest
hints and of course questions from users. If you still do not fi nd what you are looking
for, feel free to send an email to info@radialeng.com and we will do our very best to
respond to you in short order.
Now get ready to EQ like you have never EQ’d before!
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.
