bridging a b&k st202 to mono

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

I have several B&K power amps. I tried to find reference to this parallel configuration in the manuals and can't.

The manual of a Parasound HCA1000 I previously owned recommended "Single Stereo" configuration, citing that it's cleaner than bridged mode. This is simply using only one channel of each stereo amp. This allows all of the power supply output to be dedicate to a single channel. The HCA1000 has built in bridging mode with the flip of a switch. The power rating for the HCA1000 is 110 wpc both channels driven; 185 wpc "single stereo"; and 300 wpc bridged mono.

I imagine some more technically skilled folks than I can confirm this, but I assume this single stereo mode may also work with other amps too, though I wonder if dual mono amps like my Reference 4420 gain the same PS benfits.

Wouldn't you know...can't find in now. Will post it when I find it.
