To Set the Input Level:
1. Move the switch for the Input Signal Selector to the Hi position (or Hi2, if you are connecting to a factory
system with open-circuit protection).
2. Set the bass, treble, balance and fader controls on your head unit to the center (or flat) positions. Set
loudness to off. Defeat any sound-enhancement (such as DSP, surround sound or EQ) settings.
3. Insert the setup CD into your head unit and verify that the CD is playing.
4. Enter Setup mode by pressing CW and CCW buttons simultaneously for more than three seconds until
the Input Level adjustment icon
cator will show " " in the display).
5. Turn the head unit's volume control all the way up (to maximum output).
6. Using a small screwdriver on the level-adjustment dial next to the Input Signal Selector switch,
adjust the Input-Level Control up or down, while watching the icons on the amplifier's display panel.

is lit.
NOTE: If turning the control fully clockwise doesn't cause the
the Input Signal Selector to the Lo position and try again.
Once the icon is lit, stop adjusting and repeat the procedure to set the input level on the other channels.
When both check marks are lit, the input levels for each channel pair are set properly.
To Enable or Disable Signal-Sensing Turn-On:
7. While in Setup mode, enable/disable signal-sensing turn-on
by turning the rotary controller clockwise or counterclockwise
to select SEn On or SEn OFF in the display. If you have
connected a remote turn-on lead, set to SEn OFF.
8. Turn the volume control on your head unit down and remove the
setup CD. If you miss or circumvent this step, the audio system
will reproduce a loud test signal that could damage speakers when exiting the Setup mode.
9. Press and release the CW and CCW buttons simultaneously to exit Setup mode.
10. Do not adjust the Input-Level Controls further. Use the Output Gain Control to balance the channel levels
and to "tune" the system.
SETTING THE FILTERS (CROSSOVERS)
There are 98 selectable frequencies for the low-pass and high-pass
filter settings. The selectable frequencies are detailed in the table to the
right.
Getting to the Crossover Settings
Press both CCW and CW buttons at the same time for less than three
seconds and release, to activate the controls. Use the CCW and CW
buttons to navigate to the preferred crossover-adjustment parameter.
