GETTING STARTED
Making connections
Before making any connections, start by turning off your audio system and turning all
volume levels down. This helps protect equipment from turn-on transients that could damage
loudspeakers and other sensitive equipment. We recommend using a power bar with a
switch as this makes it easy to turn on and off the 500 series rack, monitors and so on, using
a single switch. Carefully plug the Q3 into your 500 series rack avoiding stress on the card
edge connector. Screw the module in to ensure it does not accidentally become dislodged.
Connections between the Q3 and the recording or PA system are made at the rear panel of
your 500 series rack. Most 500 series racks are equipped with XLR connectors. When you
plug the Q3 module into your 500 series rack, it will automatically route the card-slot input
and output XLR jacks to the module. With the Radial Workhorse 500 series rack the I/O is
augmented with ¼” TRS connectors, D-Subs and the Mix Buss signal to feed the Workhorse
mixer section.
Start by setting up the controls as follows:
1. Set all HIGH, MID and BASS frequency band controls to the OFF position.
2. Make sure all three ‘SHIFT’ switches are pushed to the left (bold effect).
This will help you to choose a preset curve that works best for the instrument at hand.
Once selected the effect can be pulled back by toggling the SHIFT switch to the right.
3. Set the HIGH PASS FILTER to off (outward position).
4. Set the GAIN control to the 12 o’clock position.
5. Set the ON switch to bypass (EQ circuit out).
The Q3 is a line level device. In other words, it is designed to take the output from a mic
preamplifi er or pre-recorded track and process the signal before sending it along to a
dynamic processor, effects device or back to the recorder.

GAIN
It is important to note that the GAIN control is always active. In other words, when you hit the
bypass switch, you are actually bypassing the coil EQ circuits. This enables you to switch the
EQ in and out to compare the effect at the same gain settings.
Connect the source to the Q3, connect the output from the Q3 to your recording system...
turn it on. Listen. You should hear audio. If not, check your connections. To check the power
going to the Q3, depress the EQ IN switch. The LED will illuminate if power is present in your
500 series rack. Now familiarize yourself with the GAIN control to check sound levels. If all is
good, return it to the 12 o’clock start position.
