(refer to the diagram on page 5). 2) Input Sensitivity Control Turn both front and rear controls all the way counterclockwise (minimum position). In this position, the amplifier will be less sensitive to the input signal from the head unit (refer to the diagram on page 5). 3) Highpass & Lowpass Crossover Controls Crossovers should be turned “OFF” during this phase of setup . Move the HIGHPASS and X-OVER switches to the “OFF” position (refer to the diagram on page 5), with these settings, full-range signal is sent to the speaker outputs. Start with the front channels. If over-excursion is detected from speakers, move HIGHPASS switch to “ON” and slowly rotate clockwise until over-excursion is eliminated. Repeat for the rear channels. 4) Head Unit The head unit should have all controls such as bass, treble, balance, and fader set to the flat or centered position. The volume control should be at the minimum setting. If the head unit has any equalization or bass management features such as boost, they should be defeated at this time. Turn head unit on, and verify that the RED status LED (logo) is illuminated on the amplifier. 5) Volume With the chosen musical track playing, turn the head unit volume control up until the maximum level of undistorted signal is heard from the speakers. (For most head units, this will be near the end of the volume control range.) WARNING! A distorted signal from the head unit sent to the amplifier can cause loudspeaker failure at higher listening levels. 4-Channel Highpass Operation Switch Configuration Diagram 8 Tuning The Amplifier - Front and Rear Speakers 6) Input Sensitivity Control Starting with the front channels, slowly rotate the control clockwise (refer to the diagram on page 5) 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. Repeat for the rear channels. 7) Crossover Controls To achieve higher undistorted playing levels from the both the front and rear speakers, the highpass crossover must be engaged. Starting with the front channels, rotate the crossover control fully clockwise (refer to the diagram on page 5). The highpass crossover point is now set at 350Hz. Rotate “Q-Tune™” Control fully counterclockwise (front channels only). Move crossover switch to the right (ON) position. 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. Repeat for the rear channels. 8) Q-Tune™ Control (Front Channels Only) Once the highpass crossover point has been determined, use the Q-Tune™ control (refer to the diagram on page 5) to increase the bass information centered around the crossover point. Setting the Q-Tune™ control is done in conjunction with setting the levels on the input sensitivity and highpass crossover frequency controls. You may find while setting the Q-Tune™ that over-excursion may be detected in the front speakers; lowering the Q-Tune™ input sensitivity or raising the highpass crossover point will eliminate this. Minor adjustments to each setting are required to fine-tune the system. Setting the Q-Tune™ is a subtle process. It is recommended that the Q-Tune™ setting be left in the 0.7 position and adjusted only after the input sensitivity and highpass crossover ranges are known. Small adjustments to the Q-Tune™ setting are all that are required to fine-tune the system. fuse9 4-Channel Operation Wiring Configuration Diagram Tuning - Front and Rear Speakers Tuning - Subwoofers Tuning The Amplifier - Front Speakers and Subwoofer (s) 1) Front Signal Routing Switch If using two sets of RCAs (independent front and rear RCAs), set the switch to DEDICATED FRONT AND REAR INPUTS . If you are using one set of RCAs for both front and rear channels, set the switch to SEND FRONT RCA SIGNAL TO REAR. (refer to the diagram on page 5). 2) Head Unit The head unit should have all controls such as bass, treble, balance, and fader set to the flat or centered position. The volume control should be at the minimum setting. If the head unit has any equalization or bass management features such as boost, they should be deactivated at this time. Turn head unit on, and verify that the RED status LED (logo) is illuminated on the amplifier. 3) Volume With the chosen musical track playing, turn the head unit volume control up until the maximum level of undistorted s...
