Step 2: Try some equalization

Play some signal into the unit
While learning the unit, you should play a CD or a multitrack
source into the equalizer. Choose a song or musical passage with a
fairly consistent level, so you can take your time experimenting
with the different features.
1. Put the mixer's main faders all the way down so you don't
distort the unit by sending it too much signal.
2. Select program 00 on the DEQ224. The fastest way to do this
is to press the [DOWN] and [UP] buttons at the same time.
This will call up a program with all frequencies set to 0 dB,
which will allow you to hear the changes you make to the
audio more easily.
3. Begin playing your source material. Bring the mixer's main
faders up gradually until the green LED over the words
SIGNAL A
the mixer's output level until the green LEDs are lit most of
the time. If the red LEDs light up at all, back the mixer's
output level down until they stop lighting up. This is
important, because the red LEDs indicate that the signal is
clipping on that channel.
4. Press one of the [BAND SELECT] buttons to select a
frequency. One of the LEDs above that button will begin to
blink.
5. Use the [DOWN] and [UP] buttons on either side of the
[POWER] switch to decrease or increase the chosen
frequency. If desired, select another frequency and repeat this
process.
6. Press the [BYPASS] button to hear the signal without the
equalization effect. Press it again to return to the EQ'd signal.

Step 3: Try a filtering effect

The answering machine
A popular vocal effect is to filter the voice to a limited frequency
range. This "telephone" effect is also called "futzing," and can be
used on any instrument or mix. Here's how to get that sound on
the DEQ224:
1. Follow the instructions for items 1 and 2 from Step 2.
2. Press all of the [BAND SELECT] buttons in the ranges
from 25 Hz to 607 Hz and from 6.1 kHz to 19 kHz on the
channel you are using.

and begin to light up. Carefully increase
SIGNAL B
Remember: if one or both of the
red LEDs light up, that means
the signal is clipping. To
prevent this, reduce the level
being sent to the proper
channel.
