Apex has been active in manufacturing Pro Audio Signal Processors
since '91. Our goal has always
been to develop original products,
e.g. the innovative Intelli-Q
and the PE series Paragraphic
Equalizer. With the new dBQzero,
Apex offers a high quality graphic
equalizer with excellent specifications and comprehensive features
at a very affordable price.
Potential users : PA-Companies,
Rental Companies, Install Companies, DJ's, musicians, etc.
WHAT MAKES THE DBQ ZERO DIFFERENT ?
- Two channels of 30 band graphic equaliser section on ISO centre frequencies and with
constant Q. Switchable 6dB or 15dB cut or boost via smooth 45mm faders.
- High and Low shelving controls per channel for smooth adjustments of highs and lows.
Will add transparency and warmth to your sound.
- High pass filter with rotary swept frequency control to easily remove unwanted noise
and rumble.
- Two notch filters with a fixed Q factor of 2 and a fixed depth of -30dB. The first has a
frequency selection variable between 20Hz and 1200Hz and the second between 800Hz
and 20kHz. This will enable you to eliminate feedback problems in a very fast way. Both
filters can be switched in or out.
- Complete 9 section LED VU-meter with Clip LED.
- Overall gain control +/- 10dB
- Complete EQ bypass switch and automatic bypass when power failure.

FREQUENCY RESPONSE
+/- 0.5 dB, 20 Hz - 20 kHz, all controls flat
POWER SUPPLY
Auto-detect 110/230 V - 50/60 Hz, switching power supply,
power switch and fuse on the back panel, power LED
on the front panel
