Hy i’m building an amp consisting of 4 k8060’s.
My question is if it is possible to " bridge" two amp’s?
And how i should do this?
Kind regards Jack de jong
Yes it is. But if you don’t know what bridging is and how to do it, I can only suggest to leave it to a more experienced electronics guy. Make a pre-amp with two outputs: one with the original signal and one with the inverted signal. Connect these two outputs to two modules (that share the same ground). The bridged speaker output is available between the two + outputs of the amplifiers.
Oké thanks, you say That i have connect the two amp gnd’s to eachother.
In the situation als it is now i have connectet two amp’s to one toriod trafo, so they share the same gnd.
Is this enough for bridging the two amp,s, our do i have to dis differt?
And where can i find a scheme of à inverter pre amp ?
Ok, if they share the same transformer, they have the same ground.
So this is ok.
Please use Google to find out which pre-amp is best suited for your application / the quality that you want.
Just to be sure: don’t forget that when bridging, your speaker must have an impedance of 8 ohms or more!
Ok thanks, i have build a pair of studio monitors wich are 100wrms @ 8ohm so thats my reason for wanting to bridge these amp’s.
Couse it is 100wrms @ 4ohm so bridged it is 200wrms @ 8 ohm?
Correct me if i’m wrong
As it is 70Wrms in 8 ohms, it will almost double to 140Wrms. In theory this can be more but current from your power supply is limited.
