EQUALIZER SECTION
17. 6-Band Stereo Graphic Equalizer (EQ).
EQ compensates for differences in source material
sound quality. In ultra-compact mobile systems this EQ
can be used to tailor the sound to the acoustical
requirements of the room. Center frequencies are
42Hz, 152Hz, 480Hz, 1.5kHz, 4.8kHz and 15.4kHz.
Faders have a center detent for an accurate "flat”
response.
Below is a typical "house" EQ curve. Notice how the
knobs above "0" balance out the knobs below. Start
with this setting if you've never used a graphic EQ
before:
0
Below is an example of a poor EQ curve because it cuts
the output volume down by 6-10dB. You have to
compensate by running the Master output higher:
0
Below is the worst sort of curve to use because you are
using EQ to add volume. With exaggerated boost you
can easily run your power amplifiers into “clipping” (see
page 5) and damage your speakers.

GENERAL EQ HINTS
• Boost the 42Hz band for deep bass tones and solid
kick drum sound. Use sparingly because this
dramatically increases demand on power amplifiers and
could drive them into “clipping” (see page 6).
• Cut slightly at 152Hz and more at 460Hz for extra
clarity. Note: Cutting is preferable to boosting.
• Boost 15kHz for a little "sizzle".
• As a general rule, less equalization is better!
18. Equalizer On/Off. This controls whether your
final output will be routed through the EQ or not.
MONITOR SECTION
19. The Monitor section includes the Program Mix
control, the Headphone Volume control and the
Headphone Jack. Connect headphones with a
standard 1/4" stereo plug. The Cue audio is sent to the
headphone amp using the Cue Assign Pushbutton
and the Pgm Mix control. The Program Mix controls
the amount of program audio in the headphones so that
beats can be matched exactly and segues are smooth
when a song is cued.
20. 12V BNC Connector allows a 12 volt gooseneck
lamp to be connected directly to the mixer. This light is
readily available from your Numark dealer.
21. Power Switch and Power-On LED.
