FEATURES AND HIGHLIGHTS
Eight Speaker-Level Inputs: If you are like
many people who like the look and features of
their factory-installed source unit but feel your
system overall is lacking power and bass, we have
good news. The DQL-8 has high-impedance
speaker-level inputs that allow it to accept am
-
plified signals from factory-installed source units
(even Bose) and output a high-quality pre-amp
signal via standard RCA connectors. This will
allow you to add better-quality aftermarket am
-
plifiers, processors and speakers to your system
while keeping the convenience features of your
factory-installed source unit. Unlike inexpensive
speaker-level and line-output converters avail
-
able, the DQL-8 offers the highest sound quality
and can handle the full signal strength of a 400-
watt amplifier.
Auxiliary Input:
Since many car audio
enthusiasts want to listen to multiple source
units, the DQL-8 provides an auxiliary input for
a secondary source. This is ideal for adding an
iPod, satellite radio tuner, or a portable turntable
to your system.
Graphic and Parametric Equalization
Controls: Car interiors vary widely in size and
acoustic make-up. Doors, kick-panels, and rear
decks don’t make the best location for speaker
placement causing your high-performance
speaker system to sound somewhat lackluster.
The DQL-8 offers 130 individual one-third and
one-half octave graphic equalization controls
for your front, rear, and subwoofer channels plus
two parametric bands for each channel. This
precise filtering of the DQL-8 allows you to select
bandwidths as narrow as 1/12 octave!
Internal Channel Summing: The DQL-8
has the unique ability to sum together mul-
tiple input channels (4, 6, or 8) from the factory
source unit into 2 channels. This is handy when
using the DQL-8 with a factory system that has
actively crossed-over signals being sent from the
OEM source unit or amplifier(s). For example, in
some vehicles there is an actively crossed-over
tweeter, midrange, and woofer in the front of the
vehicle. The DQL-8 lets you take all of those sig
-
nals and sum them together to get a high qual-
ity, full-range, pre-amp signal without the use of
any additional cables or hardware.
Dash Control For Master Volume
or Subwoofer Level Control: With the
addition of high performance aftermarket
amplifier(s) and speakers, you may feel the need
to have more control over your system. The
