Tuning - Front and Rear Speakers
Tuning The Amplifier - Front and Rear Speakers
1) Music
The material chosen for system tuning must be both clear in recording quality and dynamic in amplitude. Many audiophile “test” discs have musical tracks with both of these characteristics and should be used.
2) 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) 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
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.
