Q: Can I connect both outputs to a single speaker (bridge) ?

farkasditke73 Not directly as the two outputs are in phase. However, with a bit of DIY it may be possible. All you need to do is invert the signal sent to either input. Take a twin op-amp IC, set their amplification to 1 (connect the output through a small resistor to the inverting input (-), then feed one op-amp through the inverting input (+), the other through the non-inverting input (-). Short the amplifier's electrolytic capacitors at the output if there are any. Make sure that both outputs are on the same potential as they are now DC coupled to the loudspeakers. Alternatively, you can replace them with bipolar electrolytic caps but these are not cheap. A good result can't be guaranteed as at higher frequencies the phase shift of the two channels may not be exactly identical. It's worth a try but remember that double the output voltage means four times the output power.

The seller It depends on different definition and picture resolution.
