Impedance????

Seandtaylor99,

In your opinion, what is the consequence of halving the impedance with a Y interconnect in a vertical biamp configuration. Will it change the sound characteristics, or could it even endanger the amplifiers?

Thanks for your advice?

Jim, I highly, highly doubt it could ever damage the amps: there's just not enough power coming out of a preamp to do damage. Perhaps a really terribly designed preamp might fail.

To comment on whether the sound might change I'd have to know the output impedance of the pre, the input impedance of a single power amp, and the capacitance and resistance of the interconnect.

In most cases, with an active preamp, I highly doubt it would affect the sound. With a passive preamp, and/or power amps with input impedances under 10k ohms it might lose dynamics and roll off the high frequencies, but really you'd have to try it.

Thanks for your advice and the education!

Thanks so much for the advice and help Seandtaylor99 , sounds like you have some experience in this. I will post back after the holidays when all is hooked up and let you guys know how it does.

Thanks again
