Features and Specifications
TDA7294 power amplifier board 100W 1.0 subwoofer preamp 5532 kits (not installed)
TDA7294 subwoofer parts/ amplifier kit , uses the original STMicroelectronics (ST brand) TDA7294 audio power amplifier, low frequency processing circuit using the Texas Instruments (TI brand) NE5532, maximum output power of the circuit up to 100W. PCB layout is reasonable, no noise, cost-effective.

As long as the replacement of circuit capacity C5 *, you can change the output frequency, capacitance , with selection of range 103,223,323, 473,683,104. If need full-range output, remove C5 * . (Note: If you prefer to lower frequency, it can be replaced 224 of C4 to 474, 22k of R10 to 47K, as long as your subwoofer can withstand such frequency.)
Can be used alone as 1.0 power amplifier, and also be combined into two plates full frequency power 2.0WG application; if your existing 2.0 lack of full range output low frequency, the subwoofer can be increased all the way to three channels are combined into 2.1 applications.
Power supply transformer Range: AC double 11V ~ 25V, dual DC power supply range: ±35V. (Remark: use a DC power supply V + GND V- three lines output(make sure 3 lins is correct connect) , and can not use a single connection, such as a laptop power supply is a single one). Power minimum 50W, the greater the input of electrical power, the more of the output power amplifier, which need heasink which is not inlcuding
