bridging a b&k st202 to mono

Contact B&K directly and ask for Jerry in Technical support. From what i can remember, they don't recommend doing this with any of their earlier amps. Sean

Maybe so, Sean, but its 2 channels can always be paralleled, for double rated maximum power while maintaining its inherent ability to deliver hi current--which DOESN'T happen when bridging 2 channels of a SS amp.
.

Running the channels in parallel to the same voice coil requires massive circuit re-working, much more than the simple circuit required for bridging. Sean

Huh? One simply parallels the 2 inputs and the 2 outputs. No circuitry required, as there is for bridging, wherein one channel runs an inverted signal and then half of each channel's signal is combined at the output. B&K even has this parallel method in their manuals.

Jeffrey: I've never tried doing anything like that nor would i ever recommend such a configuration. I can think of a million different reasons why i wouldn't want to try anything like that, especially given the quality control on this type of product.

If there is any type of difference in output levels due to a channel imbalance in the amp, one channel will see the other channel as a load. The end result could be quite disastrous and very costly let alone a step down in signal purity. This is why i said that one would have to re-work the circuit internally if they wanted to do it both safely and properly.

How old is this info and is it still being included in their latest amplifier manuals? Sean
