Overview

This sub woofer kit amplifies 25 to 200Hz frequency range!
Great for subwoofer experimentation.
With an input sensitivity of 1 Vrms with an impedance of 100 Kohms, and an output power of 48W RMS class AB in 4 or 8 Ohm load.

The input signal is buffered using a small pre-amplifier stage. The left and right inputs are combined to create one mono source.

The second op amp in IC1 is used to create a low pass filter which feeds the final stage of amplification to obtain a 48 watt output.

Requires a power supply capable of delivering 2 amps plus and minus 25 to 35 volts DC. Power supply is not included.

PCB dimensions : 4.6 X 2.5

Here is the transformer you will need: 640-483
