If your source unit has front, rear, and subwoofer RCA line-level outputs, connect them to the three sets of corre- sponding inputs on your DQDX. If the source unit only has one output, the Front to Sub circuitry in your DQDX selectively routes the Front input channels to the subwoofer channels when you have the jumper in the appropriate position.

Subwoofer level. Additionally, if you press and hold the remote down for 4 seconds, the outputs of the DQDX will turn from music to Pink Noise. This will assist in the proper setting of the EQ and Delay. When the DQDX is in Normal mode, pressing the remote momentarily will defeat all process- ing on the DQDX (Equalizer and Signal Delay).

Under the Covers - Internal Jumpers You can optimize your DQDX using most of the controls mounted on the top of the chassis. However, we recognize there are situations where advanced users may have the need to configure the DQDX for specific applications.

DQDX. If your source unit has only front and rear inputs, just connect these to the front and rear inputs on the DQDX and switch this “Sub to Front” jumper to the ON position. Changing this jumper to ON will route the low pass signal (as defined by your crossover selection) to the Sub outputs of the DQDX.

The following steps will guide you in delaying the appropriate speakers for just a few milliseconds, so the DQDX is able to allow the different signals to arrive at the same time, putting the driver in perfect acoustical alignment.

Take a careful look at the “curve” on your analyzer and how one frequency combines with the next. There is no one curve that will satisfy every person, as we all have different tastes.

The key in this area is to have enough speakers and power to produce the amount of bass you desire but don’t use the controls on the DQDX to try and force your speakers to produce sounds they can’t. Too much bass boost creates a condition called “speakerus explodus”, which is not pretty.

Many autosound systems start a gradual decline in this area which is why speaker placement is very important. The DQDX only gives you a few controls in this area because too much boosting can really make a speaker sound un-natural.

The DQDX comes with a 24/dB Octave Linkwitz Riley alignment crossover that lets you select the exact crossover point you need for your system. The crossover frequency markings on your DQDX are for reference purposes only. The exact crossover frequency can be found in...
If you are hearing music, go back to step #2… If you are hearing voices, please go see a doctor! Starting with the DQDX input level controls, adjust the control knob clockwise until the Input Maximized LED just begins to flicker.
Parallel Outputs The DQDX has our unique Front to Sub circuit input that allows the Front input signal to feed the Subwoofer outputs, when no Subwoofer input is available. This allows your DQDX to accept front and rear inputs channels and give you Front, Rear, and Subwoofer output channels.
