  1. Thanks I now see that the amp looks at the load as half the connected impeadance on each side not the total load on the output in general. Two 4 ohm speakers across the bridged out put looks like a 1 ohm load to each side of the amp not a 2 ohm load. Everyone was great help. Thanks
  2. One creates the interesting effect of a soundman running back and forth between the board and the amp every time the thermal protection kicks in and the other allows the two output transformers to carry their loads properly. I have never seen a solid-state amplifier that will handle a 2 ohm bridge-mono load. Bridging an amplifier is tying both the outputs together so as far as the amplifier is concerned, a 4 Ohm speaker load is seen as a 2 Ohms load when bridged. Therefore a 2 ohm load would be seen as 1 Ohm or worse, as the Speaker specs are for a nominal Ohm reading. Most 8 ohm nominal speakers are actually 6 ohms or less dependant on frequency. That is why 2ohms bridged is never normally supported by any pro amplifiers as it is effectively a short on the output. "Safe with all types of load' could mean that if you drive the amplifier into a short, it will protect itself from overheating, etc. Rob I guess there is somthing I'm missing. Is two 4 Ohm speakers paralleled accross a bridged output 2 ohms?
  3. I don't know. That's why I asked. A 2 ohm load is a 2 ohm load. What is the difference in running a two ohm load on each side of the amp, and running 2 ohm on a bridged output. I would suspect it would have something to do with the dampening factor in cable lengths. However I propose to us no more than 5 feet of #8 cable and want to know if it can be done without damage to speakers or amps. Maybe a Crown Rep could clear this up for me. As always I thank you for your Knowledge.

  5. I noticed in my manual a phrase " safe with all loads", however in the specs there is nothing stating what the bridged output would be at 2 ohms. Does this mean you don't recommend running the bridged mode lower than 4 ohms? Thanks in advance Greg Fortner
