The CVM-3 is a powerful bass component. This device is equipped with several / different bass output
selections, if you should need to change the settings, please use the chart below for guidance. We
recommended listen to the factory setting before changing your bass output settings.
Recommended Settings
Setting Amplifier Input Voltage Minimum Speaker Size
2.5 Volts 3.0 Volts or less
8"
5.0 Volts 5.0 Volts or less
10"
7.5 Volts 7.5 Volts or less
12"
10 Volts 10 Volts
15"
The bass response in a system is affected by four factors:
1. The acoustics of the vehicle
2. The location of the speakers
3. The source music
4. Speakers and speaker enclosures
Because of the variations that happen during the recording of music, we developed CVM-3 to restore any low
frequencies lost during the process; however, the acoustics of various environments and recordings are
different. The sweep control allows you to select a center frequency (the frequency most affected) between
27 and 63HZ. The “Wide” control then allows you to control the shape of the filter centered on the sweep
frequency( how “Narrow” or “Wide” you want the boost)
Note: FOR ADVANCED USERS!!
There are jumpers underneath the top panel
located on the top right section of the PCB.
