POWER ON LED - This light will turn on when the amplifier receives a +12V turn on signal from the radio. If the amp is properly wired, but the light does not turn on, there may be a short circuit condition that the amp is protecting itself from.
BASS BOOST - This control provides additional bass in the 45Hz area to give a stronger low end “feel” to the bass. Once switched on, this will also allow the amp to be driven into distortion sooner so the user must be aware.
GAIN CONTROL - The gain control allows for a range of

REMOTE GAIN CIRCUITRY
Should the installer wish to create their own remote gain control, or attempt to daisy chain the gains of multiple amps, refer to the adjacent circuit design for proper connection. This should ONLY be attempted by a very highly qualified installation technician. If improperly done DAMAGE WILL OCCUR to the amplifier and WILL NOT be covered by warranty! (We put this information in this manual because of the interest of our highly skilled Blaupunkt installers - the average consumer should NOT attempt this on their own!)
You should ONLY loop the SIGNAL pin to other amps - DO NOT carry the ground and +12V pin voltages to adjacent amps.
