  1. keep in mind that the DD1 is measuring audio signal. just because you are hearing distortion doesn't necessarily mean you have a distorted audio signal. your speakers may be creating the distortion. also keep in mind that setting your gains with the DD1 is getting the most power out of your amp without distortion. example, if you set your gain to 34 without the red light but it comes on at 35. if you boost a frequency, it's like turning the volume up to 35 on that one frequency.
  2. wish I was going. apparently whatever it is the guys at HC were stoked about everything about what they did. When you are going to be the guest at one of those classes? you're next on my list.
  3. the AMM1 is measuring live, so if there is no load there's no measurement. if you have a resistor pack you could use the AMM1 to help set gains. resistors with a high wattage rating become very expensive very quickly. i'd just fork over the money for a DD1 or DD1+. now if you can get a measurement without a load, that's beyond me of how you could make that happen without a resistor of some sort.
  4. no matter what information actually get put out there, people will still buy CCA wire. 2 main reasons, 1 is money and 2 is ignorance (whether it be willing or unwilling). too many people use the excuse of "i'm not good at math" as a reason to be stupid when it comes to anything that has a number. same applies here. companies that make CCA wire are more at fault than the consumers. they advertise fluff numbers to push product.
  5. even if your amp did create a dirty signal at .5 ohms compared to 1 ohm, you can't get rid of that. that's an amp issue. the DD1 is helping you get the gain matched to the signal output from your source with overlap if desired.
  6. resistors oppose current flow not voltage. you'd have to use a substantial value of resistance to lower voltage. example would be using a resistor to get rid of amp turn on pop in Ford vehicles. to alter voltage with resistors you'd have to use it in a voltage dividing network type of scenario.
  7. it's not louder. it's lower in volume by 10db from the original 0 db recording. so when you set the gain with a 0 db tone it'll be at x location, then when you go back to set a 10 db overlap your amp's gain will be set to play 10 db louder to equal the original 0 db tone. test, play tone and set amp with a 0 db test tone then meter it on that tone. then play -10 db tone then set amp gain then play test tone and meter it again. those numbers should be equal to one another. so when you play music which is usually recorded at -3 db to -7 db, it'll still be clean power b/c if it does distort or clip it'll be in such minimal intervals that it won't or should damage anything.
  8. i'd isolate the yellow top, resting voltage is 13.1 on those.
