Members Shamdog Posted January 7, 2010 Members Share Posted January 7, 2010 I have a Crown 800CSL to run my monitors. I want to run 2 daisy chained off of each channel for a total of 4. The question is, the "Monitor " out from my mixer is one 1/4 jack. Don't I need two inputs to the amp (left and right) to use both sides? If so, can I buy a splitter to split the single "monitor" signal into two so that I can use both sides of the amp? Or am I a complete moron?

Members soul-x Posted January 7, 2010 Members Share Posted January 7, 2010 Yes. Do it with a Y-cable. What you DO NOT want to do is to use the "Parallel Mono" setting on your Crown. Crown's idea of what constitutes "Parallel Mono" compared with every other individual on earth is beyond bizarre. I think they were probably heavily drinking when they came up with that bright idea.

Members soul-x Posted January 8, 2010 Members Share Posted January 8, 2010 So, what did they do that is so bizarre? The old crown parallel mono mode doesn't split the input signal into the two sides. It reconfigures the output stage of the amplifier so it can drive as a single channel amp at lower impedance loads. It's actually kind of a neat feature, but it is confusingly named and awkwardly implemented, especially taking into account what users are expecting it to do.

It reconfigures the output stage of the amplifier so it can drive a single channel at lower impedance loads.Actually you have to do the reconfiguration yourself by running a jumper between the two "hot" outputs. I suspect that if you leave off the jumper it would act like any other parallel mono amp? Anybody know? Link to comment Share on other sites More sharing options...

Members jwlussow Posted January 8, 2010 Members Share Posted January 8, 2010 Won't a 1/4" jumper between the two inputs work? Link to comment Share on other sites More sharing options...
Members RoadRanger Posted January 8, 2010 Members Share Posted January 8, 2010 Use the jumper.Does it use a single feedback path or ? Link to comment Share on other sites More sharing options...
Members RoadRanger Posted January 8, 2010 Members Share Posted January 8, 2010 Won't a 1/4" jumper between the two inputs work?You mean a "Y" cord, right? The manual sez the inputs are 1/4" balanced but doesn't specifically say if they are TS or TRS Link to comment Share on other sites More sharing options...

CMS Author Craig Vecchione Posted January 8, 2010 CMS Author Share Posted January 8, 2010 Won't a 1/4" jumper between the two inputs work? Nope, this amp in standard input config only has one TRS input per channel. If his has the MT-XLR aux panel, he can use the TRS as jumpers to connect channels, and use an XLR for his input.

Members RoadRanger Posted January 8, 2010 Members Share Posted January 8, 2010 Balanced TS would be a neat trick.They do have a ground lift for the inputs so you could do balanced (sans ground) with a TS jack. Not probable but it is a weird amp . EDIT> I looked again and they do show a diagram of the input being TRS so all's well with the universe .

Members agedhorse Posted January 8, 2010 Members Share Posted January 8, 2010 Who, me? No, Roadranger. The parallel mono mode must use the jumper for the load to be properly balanced. Otherwise there are additional variables that come into play. This is (one reason) why the feature was abandoned. Link to comment Share on other sites More sharing options...

CMS Author Craig Vecchione Posted January 8, 2010 CMS Author Share Posted January 8, 2010 Nope...maybe that's why I got it for $65 ..or because it's about 20 years old. Not that this is a bad thing, but it does affect price. Link to comment Share on other sites More sharing options...
