CONTROLS AND SETUP

TROUBLESHOOTING

SETTING THE

CROSSOVER(S)

Determine your system plans and set the crossover mode switch accordingly. If your system design does not include a subwoofer with the CS60.4, set the crossover mode to FLAT and skip to “Setting Input Sensitivity.”

Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible.

Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. Adjust the crossover frequency to limit bass and provide increased system volume with less distortion.

For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer.

If using the CS60.4 or CS60.2 to drive a subwoofer(s), set the crossover mode to LP (low pass).

SETTING INPUT

SENSITIVITY

1.Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise).

2.Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track.

3.On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard.

NOTE: After the source unit is on, blue LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to “Troubleshooting” guide at right.
