Part of National's Overture product line, this demo board contains the LM4651 driver chip and LM4652 Class-D output stage. Very nicely made board with Deltron power input & speaker output connections. One is on the top & visible at right side and the other four are on the underside of the PCB. Board is called out as "subwoofer amplifier" and has a single RCA input. I cannot remember if it has a crossover filter built-in or not. It is ready to use.

$50 USPS MO / includes S&H US48, others inquire.
