A GUIDED TOUR OF DQS
1) Inputs: The DQS has six RCA inputs that
need to get their audio signals from the main
source unit. If your source unit only has two or
four outputs, fear not, just use the front or rear
inputs. See the system diagrams in this manual
for some cool system ideas.
2) Input Level: These knobs allow you to
maximize the signal level from your source unit
that goes into your DQS to achieve maximum
signal-to-noise ratio. Keep in mind that despite
what the literature says, most aftermarket source
units produce a relatively low voltage signal when
it comes to playing music at normal levels.
3) Input Maximized Indicators: These
nifty LEDs (Light Emitting Diode if you are curi-
ous) indicate that you are supplying the DQS its
maximum amount of signal voltage. If the LED
indicators never come on, don’t assume that it is
not working (since LEDs rarely break) but you
might consider adding a line driver to your system.
4) Output Level Controls: Although your
DQS has the ability to increase your signal voltage,
your amplifiers may not necessarily accept that
much signal. These controls allow you to regulate
the proper amount of pre-amp signal from the
DQS to the amplifiers.
5) Equalization Overload Indicator: This
convenient LED indicates when the DSP (digital
signal processor) of your DQS is clipping or distort-
ing. The usual cause of this is having the “Input
Level” turned up too high or you have to much
overall boost on the various frequencies of your
equalizer.
6) Select: This button allows you to select one
of the various equalization, display, or memory
modes of your DQS.
7) Navigation Arrows: These multi-func-
tion buttons perform a number of duties, depend-
ing upon which mode your DQS is in. You can do
anything from applying boost or cut to your
equalization filters to changing the display bright-
ness. However, if you get the high score, you
cannot enter your initials!
8) Output Voltage Indicators: These
brightly colored LEDs indicate the level of signal
voltage that is coming out of the various outputs
of your DQS. Use these to assist in level matching
your source unit with your amplifiers.
9) Outputs: These RCA connectors should be
connected to the next component(s) after the
DQS, usually an amplifier. Do not connect any
speakers directly to your DQS or to any home
appliances, like your toaster.
