Members BenBroChill Posted December 31, 2009 Members Share Posted December 31, 2009 Ok could someone explain to me what the differences are? I understand that Bridge Mono is Balanced and Parallel is not, but I have a Crown Power Tech 3 and in the manual it says that Bridge is rated for 8-16 ohm load and Parallel is rated for 2-4 ohm load. I'm not saying I will be doing either I would just like to understand this. Link to comment Share on other sites More sharing options...
Members agedhorse Posted December 31, 2009 Members Share Posted December 31, 2009 Crown is the exception to the rule on what parallel mono MAY mean. There ae two possible meanings and Crown used them interchangably. Crown is/was the ONLY manufacturer that reconfigured the output stage for the different parallel mono mode. This is a CRITICAL detail. You need to read the manual for your specific model to determine this. Link to comment Share on other sites More sharing options...
Members BenBroChill Posted December 31, 2009 Author Members Share Posted December 31, 2009 I talked to crown tech support and figured everything out. I do appreciate the continuous help within this forum though.Thanks Link to comment Share on other sites More sharing options...
Members agedhorse Posted January 1, 2010 Members Share Posted January 1, 2010 No problem. Crown really confused everything with their dual use of an opertating mode depending on which product line you are talking about. Does your amp use the input signal routing method or the output stage reconfiguration method? I don't recall. Link to comment Share on other sites More sharing options...
Members Coaster Posted January 1, 2010 Members Share Posted January 1, 2010 so besides routing input 1 to both channel 1 and 2, what is the other possible parallel mono you speak of? Link to comment Share on other sites More sharing options...
Members agedhorse Posted January 1, 2010 Members Share Posted January 1, 2010 so besides routing input 1 to both channel 1 and 2, what is the other possible parallel mono you speak of? Reconfiguring the way the output stage operates, essentially paralleling the output stage to increase current capability and output stage dissipation capacity. Here's the data from the Crown CT series: CT-200 OUTPUT POWER110W/Ch 8 Ohms155W/Ch 4 Ohms305W Bridged Mono 8 Ohms225W Parallel Mono 4 Ohms315W Parallel Mono 2 Ohms Note that the amp is rated at 155 watts/chan in stereo mode at 4 ohms, no 2 ohm rating BUT in parallel mono, it delivers one channel of 315 watts into 2 ohms. That's the giveaway that something is different internally. Link to comment Share on other sites More sharing options...

Simple and understandable after he told me, but man thats a bit of a pain when you can't find anything about it in any manuals or tech specs.

This is why I am very careful when I make my recommendations, suggestions and comments. There are a lot of details accumulated over 25+ years of doing this.
