ImaNoob Posted March 23, 2014 Report Share Posted March 23, 2014 Ok so i gain matched the other day, When checking the voltage one was higher then the other one was 49.? and the other was 60 ? Everything on deck Flat , Truck off etc..Know how to use the DD1 .Set Gains with dd1 first. Amp A was the lower setting. So set 40hz track CC1 disk. Hooked up probes to amp A+ speaker and Ground distro. Attached other end to CC-1. Pressed and held Off button for a few seconds. Turned on/ entered comp mode. Turned deck up to signal , Read, on to Amp B turned gain down .. Matched. 63 hz track Set freq to 63 amp A and B, turned Subsonic on.....Im i doing something wrong ? Truck was off whole time 12.5 volts at amps constant( Smd Volt Meter) Any Ideas though ?

ROLEXrifleman Posted March 23, 2014 Report Share Posted March 23, 2014 When I gain match I use the DD-1 to gain set, my cc-1 (when needed) to x-over set, and them my DMMto bring the amps down to whatever voltage I want them at. If one is ay at 56 volts and the other at 59 I'll just bring them both down to 55 and call it a wrap. I play everything on the safe side though Quote Rolex you sicken me.

ImaNoob Posted March 23, 2014 Author Report Share Posted March 23, 2014 Ill Probably end up doing that if i cant figure out what im doing wrong. I feel like the CC-1 Should be doing that ya know..

ROLEXrifleman Posted March 23, 2014 Report Share Posted March 23, 2014 I'm with you man. I don't use my CC-1 to its full potential that's why I do that part with the DMM. Maybe someone else will chime in with the answer for ya. I'm gonna spend some time on the bench with the cc-1 when I can to learn all it's uses. Down and dirty though, bust out the dmm if you have too. Quote Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
tacomaguy1 Posted March 23, 2014 Report Share Posted March 23, 2014 Dmm to gain match is easy Try that Quote Team Flex Issues Link to comment Share on other sites More sharing options...
audiofanaticz Posted March 23, 2014 Report Share Posted March 23, 2014 Since amps are nearly never the same, look at Rockfords that come with a birth sheet for example. You have one bdcp2500 that does 2900wrms @ 1ohm, and you have another bdcp2500 that does 3300wrms @ 1ohm. They are the same amps, but yet one is more powerful. So when using the gain matching feature on the CC-1 it is gain matching your amplifier by wattage, not A/C voltage (like your Digital MultiMeter is). When you are volt matching by voltage via dmm and you have 2 of the same amps and one is slightly stronger, one amp at say 50volts is going to be louder then the other amp at 50volts meaning your amps ARE NOT VOLT MATCHED.

I'm sick today man, so that might be why I'm not getting this part. say that one more time? Quote Rolex you sicken me.

ImaNoob Posted March 23, 2014 Author Report Share Posted March 23, 2014 Yeah only reason i checked With DMM is because in Steves video. When he was done he checked with dmm and all amps were the same voltage ...So just run em as IS.. Thats what your saying ?

audiofanaticz Posted March 23, 2014 Report Share Posted March 23, 2014 Hard to explain what im trying to say. But the DMM and the CC-1 are going about matching the gains slightly different from my understanding. if you where to dyno the mismatched amp that requires more voltage to make the same power on the cc1 you would see the wattage would come out the same as the first amp, where as if you volt matched with a dmm as the first amp your dyno results would be different even tho they are reading the same voltage. however I guess it will matter how much farther you turn the screwdriver after the light turns on..

I'm not sure how the CC-1 does it either. I just use it to set x-over points, never got around to using it for gain matching if you where to dyno the mismatched amp that requires more voltage to make the same power on the cc1 you would see the wattage would come out the same as the first amp, where as if you volt matched with a dmm as the first amp your dyno results would be different even tho they are reading the same voltage Ok, heres where I'm loosing it. I'm reading this as even though the voltage output is the same there will be a difference in wattage? I know it's tuff to explain. It's tuff to understand for me right now!! lol Quote Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
