Front High-Pass Crossover Frequency Adjustment
- Adjusts the crossover
to match your speaker system. The crossover frequency can be adjusted from
32Hz - 400Hz or from 640Hz - 8kHz with the crossover frequency multiplier
switch.
•
Rear High-Pass Crossover Frequency Adjustment
- Adjusts the crossover
to match speaker your system. The crossover frequency can be adjusted from
32Hz - 400Hz.
•
Subwoofer Crossover Frequency Adjustment
- Adjusts the crossover to
match your speaker system. The crossover frequency can be adjusted from
45Hz - 250Hz.
• Frequency Multiplier
Switch
- When engaged, this switch increases the
crossover frequency by a factor of 15. Example: If the frequency is set for
70Hz, moving the frequency multiplier switch to X15 changes the setting to
1.05kHz.
•
Output Level Controls
- Seperate Front, Rear and Subwoofer Output Level
Controls allow you to set the nominal operating level of the crossover. The
crossover’s output level ranges can accommodate virtually any brand of
amplifier.
•
Subwoofer
Boost Control
- The crossover also features a “high-Q” (i.e.
narrow frequency band) Bass Boost circuit. It acts much like an equalizer,
with adjustable gain (from 0 - +18dB) with a center frequency adjustable from
25Hz- 100Hz. Use this feature to tune low-frequency audio response to
compensate for a less than ideal subwoofer enclosure design. The added
boost produces rich, full bass tones that are normally difficult to reproduce in
the car audio environment. Use the Freq dial to set the Boost Freq and the
Sub Boost Level dial to set the amount of boost. Note: If Bass Boost is
undesired, set the Sub Boost Level to 0dB.
•
Phase Switch
- When set to 180 degrees, this switch reverses the phase of
the subwoofer output signal. This is used for fine tuning the bass response
after the installation is complete.
•
Power Indicator
- The power indicator will light up when the crossover is on.
•
Front/Rear
Input Switch
- This switch allows use of a 2 channel input to
drive both the front and rear inputs.
•
Sub Input Switch
- This switch allows the signal from the front and rear
channels to be directed to the sub input when a dedicated sub input is not
available.
•
Remote Sub Level Control
- When the remote sub level control is plugged
into the QA3X, the sub output level control on the QA3X will be defeated.
Instead the remote sub level control will set the sub output level.
