Declaration of Conformity

Determine your system plans and set the crossover mode switch accordingly. If you plan to use the CS50.4 to drive full- range speakers, set the crossover mode to FLAT and skip to “Setting Input Sensi- tivity.”

Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least per- ceived 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 CS50.4 to drive a subwoofer(s), set the crossover mode to LP (low pass).

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 vol- ume 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, indicat- ing the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to “Troubleshooting” guide below.
