Woofer Speaker Amplifier Circuit Diagram. Bass speaker woofer tda7293 power audio amplifier. Since no ics are used the circuit is very robust and can be easily assembled.

For splitting the signal you can use resistors for basic splitting. If you need exactly 6 you can play a round with the resistance on the input. This is the circuit diagram of a fully transistorized sub woofer amplifier that can produce an output of 100w there are seven transistors including four in the output stage.

On page 5 you ll find typical applications with several circuit diagrams.

The transistors q1 and q2 form the preamplifier stage. Circuit diagram dc dc converter voltage converter sound speaker speakers electronic news electronic schematics audio amplifier. Uhf tv preamplifier circuit diagram. Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal.
