Getting Started
READ THIS PAGE!!
Even if you never read manuals, please
read and digest the safety instructions
on page 2, and this page before you
begin using the Quad EQ. See page 22
also, if you are in the mood.
Connections
If you already know how you want to connect the
Quad EQ, go ahead and connect the inputs and outputs
the way you want them.
The following steps show how to use the Quad EQ in a
simple stereo system using channels A and B:
1. Turn off the power switch on the rear panel.
2. Connect the left main mix output from a mixer into
the channel A input (XLR or TRS connectors on the
rear panel) of the Quad EQ.
3. Connect the right main mix output from a mixer
into the channel B input (XLR or TRS connectors
on the rear panel) of the Quad EQ.
4. Connect the channel A output of the Quad EQ to
the left main input of your powered speakers or
amplifier.
5. Connect the channel B output of the Quad EQ to
the right main input of your powered speakers or
amplifier.
6. Connect the supplied microphone to the MIC input
of the Quad EQ.
7. Plug in the detachable linecord to the Quad EQ,
and connect it to a live AC outlet.
8. Turn on your mixer and the Quad EQ.
9. If you have powered speakers, turn them on. Other-
wise, hook up your speakers to the amp and turn it
on. Adjust your powered speaker or amplifier level
controls to however the manufacturer recommends.
(This is usually all the way up.)
10. Play something into your mixer and adjust the
mixer until your speakers are playing along nicely.
The Quad EQ will have no effect if the EQ filters are
all flat. The sound system will still play, even if the
Quad EQ is off.
Measurement Microphone
1. Position the supplied microphone in a suitable
location. For example, if you want to measure at
the front of house position, set it there on a stand,
equi-distant from the main left and right speakers.
To measure the monitors, set the mic five or six feet
away from individual monitors, or set it up equi-dis-
tant from two or more monitors.
Master Meter and Level
1. Press CHANNEL SELECT A and B at the same time
to link these channels. Now, any changes to the EQ
or levels will affect both channels equally.
2. As your music is playing, you will see the MASTER
LED ladder (the right-most ladder) acting as a
meter in green.
3. To adjust the master level, press the button below
the MASTER LED ladder, and rotate the KNOB. The
level is shown in the DISPLAY, and in the MASTER
LED ladder.
EQ Setting
1. To adjust the EQ, press the buttons beneath any of
the 30 LED ladders. Then adjust the level using the
KNOB and the DISPLAY. A red LED shows the level
in the LED ladders. Be inclined to cut EQ levels
more often than boosting them.
RTA
1. Press RTA, and the LED ladders will show the signal
levels at each filter frequency. This can help you
choose frequencies that may need EQ adjustment.
You can view the RTA analysis (green) and the EQ
settings (red single LED) at the same time. Press
RTA again to turn it off.
NOISE and MIC
1. Press EDIT and NOISE, and adjust the noise level
using the KNOB, until pink noise is playing through
your speakers. Press the KNOB again, or EDIT to
return.
2. Now, if you press NOISE and CHANNEL SELECT A
or B, you will hear this noise in your speakers.
3. Press MIC, and the Quad EQ now receives signals
only from the microphone, not from your mixer.
4. The DISPLAY shows the SPL level.
5. Press EDIT and MIC, and adjust the KNOB until the
mic signals appear in the 30 LED ladders.
6. Adjust the EQ levels to smooth out any bumps or
dips due to room modes, and lessen the chance of
feedback.
7. Turn off NOISE and MIC when you are done, and
your system will be ready for the audience. The
measurements and EQ adjustments will take the
guesswork out of setting up your system, but we
can’t sell you a good set of ears. That’s illegal.
