Confusion about TDA7388


TDA7388 has 4 outputs, can you connect 4 in parallel to make one output to increase the power?
Can the 4 pins of 9.5.17.21 be connected in parallel to a speaker with a higher power, and the 4 pins of 7.3.19.23 can be connected in parallel to the other end of the speaker?
What does 4-pin ST-BY mean?
11.12.15.14 Are the 4 input terminals used independently?
Looking forward to ur help!
Thanks.

You can't parallel the outputs for more power no. More power requires more volts. But you can parallel to drive a lower impedance driver and get more power into that. You'd need capacitors to parallel the outputs due to the DC offset.

ST-BY means 'standby' - it puts the amp into a lower power mode.
