This circuit described here uses two cis
tda 7294 for use in stereo (2 x 80Watts) or bridge mode (1x 180 Watts), to configure this setting just four jumpers. To facilitate mounting the circuit has power supply attached.
The power is kind of simple symmetrical with a bridge rectifier 6A, and two large electrolytic capacitors , 10000μF the 22000μF/50v. This Power supply will for the two modules. The processor is recommended 22-0-22 to 28-0-28 / 5A, depending on the quality of the transformer is recommended at least 6 amps of current.
Circuit Amplifier TDA 7294 Stereo
Another application suggestion is the BRIDGE configuration, where two TDA7294 are used, In this application, the value of the load must not be lower than 8 Ohm for dissipation and current
In stereo, all jumpers must be open and the speakers (speakers) are plugged into connectors Lout and Rout and audio input connectors in the Lin and Rin. In the amplifier in bridge mode all jumpers should be closed and the
audio output Lout is (+ the speaker) Rout (- the speaker) and audio input will be Lin, Rin will be shorted to ground via JB2.
