Thank you for purchasing the Cadence Model CEQ-777 4 Band Parametric Equalizer. With proper installation and care the CEQ-777
will provide you with years of performance and reliability.
The CEQ-777 is intended for those who value the acoustic benefits of a multi-band parametric equalizer coupled with the power of
controlling four amplifier channels and two independent sub woofer channels directly from the automobile dash board.
The CEQ-777 is a passive pre-amp equalizer requiring external amplification to power speakers. It provides 2 channels of front
output, 2 channels of rear output, and 2 channels of subwoofer output.
PARAGRAPHIC GRAPHIC EQUALIZATION
Every car interior produces at least one sharp peak or dip in the frequency response that results in highly unnatural sound reduc-
tion. But the exact frequency and its level of intensity depend on unpredictable factors such as the size and volume of the interior,
type of material used for the interior (cloth, leather, vinyl), whether a window is open or how many passengers are onboard.
Because of these variables, even a multi-band graphic equalizer will not be able to control a particular frequency without unneces-
sarily affecting others. The listener is therefore faced with either unwanted alterations of frequencies or having unnatural peaks and
dips, which might result in boomy bass, muddied vocal range or harsh treble response.
This unit is the first production pre-amplifier to incorporate a specific bandwidth parametric equalizer with 12dB boost or cut on its
seven bands. It can compensate for the seven acoustic anomalies unique to the automotive environment. This unit easily becomes
the “mission control center” of any high end automotive sound system.
When increasing the boost of any frequency you are actually increasing the output voltage of the equalizer to the amplifier. Please
be sure that your amplifier has enough “head room” and is capable of handling the source increase with out clipping. It is also
important that your speakers are capable of reproducing the frequency range which you have chosen to boost without being over
driven. For example, do not attempt to boost a 60Hz signal to a small midrange driver, this will only cause the midrange to burn
out. The proper procedure for a successful installation is to incorporate either an electronic crossover or passive crossovers to help
control which frequencies will actually reach the proper speakers.
For basic installations in a vehicle with larger speakers in the rear and smaller speakers in the front, utilize the fader control to
adjust the amount of power reaching the speakers. By turning the fader more to the rear position, more power will be distributed
to the rear speakers, thereby protecting the smaller speakers in the front of the vehicle.
