Tuning The Amplifier - Front or Rear Speakers
WARNING! A distorted signal from the head unit sent to the amplifier can cause
loudspeaker failure at higher listening levels.
6) Input Sensitivity Control (Gain)
Slowly rotate the control clockwise (refer to the diagram on page 3) until
maximum undistorted playing level is heard from the speakers. Listen closely for
bottoming from the speakers. If detected, rotate the input sensitivity control
counterclockwise until it is eliminated.
7) Crossover Controls
To achieve higher undistorted playing levels from the main speakers, the Highpass
crossover must be engaged. Rotate the crossover control fully clockwise (refer to
the diagram on page 3). The highpass crossover point is now set at 200Hz. Q-Tune
should be set to off.
Slowly rotate the input sensitivity control clockwise until maximum undistorted
playing level is heard from the speakers. Listen closely for bottoming from the
speakers. If detected, rotate the input sensitivity control counterclockwise until it is
eliminated. Slowly rotate the highpass crossover control counterclockwise while
listening for bottoming. You are lowering the crossover point, which means that
more bass signal is being sent to the speakers. If bottoming is detected, rotate the
input sensitivity control counterclockwise until it is eliminated and/or rotate the
Highpass crossover control clockwise to raise the crossover point.
8) Q-Tune
™
Control
Q-Tune allows for +6dB boost of bass information centered at 45Hz and is not
typically needed for full range speaker applications.
