EQUALIZER SECTION
16. 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 6) and damage your speakers:
0
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 5).
• 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!
17. Equalizer On/Off. This controls whether your
final output will be routed through the EQ or not.
MONITOR SECTION
18. 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.
19. 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.
20. Power Switch and Power-On LED.
