Description
The JBL(r) 4-channel amplifier is crafted with fully-marinized circuit boards to keep salt and corrosion away from the critical circuit path. The on-board 12dB electronic crossovers provide tuning options for systems of any size, and the variable bass-boost circuit provides additional bass tuning to optimize performance, regardless of location.
