C-Fizzy Posted August 13, 2011 Report Share Posted August 13, 2011 I was wondering this too. I just bought a aq1200d and the clipping light comes on but i hear no distortion in the speakers at all it seems like the light comes on too soon not extremely soon but it seems i can get quite a bit louder before it distorts. you can't always hear clipping. just 'cuz it doesn't sound distorted, doesn't mean you aren't killing your subs. Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy? Link to comment Share on other sites More sharing options...
canderton01 Posted August 13, 2011 Report Share Posted August 13, 2011 (edited) It would be really nice for someone with a DD-1 to tune an AQ amp. Make a video and have the DD1 and the bass nob side by side just to put all the theories of how accurate the clip light is to rest.

BeatBox Posted August 13, 2011 Report Share Posted August 13, 2011 They have already been proven to NOT be very accurate, they are signaling way before clipping. Im not sure what they are measuring but Crescendo already decided to stop using them all their new line starting this month i think will have a clip light in the bass knob the ppl who bought the new line of amps(black/copper) but got them before this month will be able to send them back to get it added on if they wish Quote Link to comment Share on other sites More sharing options...
Decaf Posted August 13, 2011 Report Share Posted August 13, 2011 (edited) they detect completely different things DD-1 red light turns on when anything besides 40 or 1000hz is detected... Clip lights on amps DO NOT detect DC voltage on the speaker outputs, they light when rail voltage meets a set point and thats why we trust you with badass, unclipped music (not that this is the thread but im finding out that when i export in audacity with a clean all blue song and import it after there are a few red lines that appear.... just found this out today, ugh. negligable amount but that explains a few people complainin) Edited August 13, 2011 by Decaf Quote Link to comment Share on other sites More sharing options...
kirill007 Posted August 13, 2011 Report Share Posted August 13, 2011 ive also heard that they are acutaly quite accurate.. who knows was jsut curious on that is all According to my TPI440, the AQ clip light is almost spot on.... Now I have a newer 2200d, real new. My older version did vary slightly. I would trust the clip light. Now are you goin to say my oscope is bad because its not a DD1? LOL the TPI was the thing TO HAVE here before the DD1. ... Don't listen to this person.. Don't trust the clip light, except if you have to. But it only detects clipping made by the amp.(by measuring rail voltage like decaf said.) DD1 is not a oscope, DD1 is better since it can detect distortion. The oscope is still good if you know how to use it, and a handheld one isn't the best option. Quote Thinking is the root of all problems... You ALWAYS get what you pay for.

Kush Killer Posted August 13, 2011 Author Report Share Posted August 13, 2011 hmm some good info.. still mixed reviews on its accuracy i see.. i jsut wanted to know what it was measuring.. and rail voltage iskinda what i was thinking but wasnt sure..

The oscope is still good if you know how to use it, and a handheld one isn't the best option. I didn't say the dd1 sucked. I said in my experience, the oscope was close to the aq clip light. I understand how each is measuring different things. And the TPI is very decent, measured nearly the same as my old school bench scope.... The dd1 is an accurate way to measure distortion, but using the clip light still has a use. It's also very nice to monitor the music, as a lot of music has different recording qualities and properties. So even if you set the gain with a dd1, the clip light still has a very good purpose. And from what I read, crescendo is going WITH the clip light.

In reality, the rail voltage does matter. It's not a direct monitor of the audio signal, but it is a good indicator of what output is going to the speaker.

And from what I read, crescendo is going WITH the clip light. TO the red: TPI is very decent, but because it's handheld you can barely see distortion(or not at all), you need a very trained eye. THe big oscopes are better because it's easier to read and is more detailed. Purple= The clip light doesn't detect clipping before the amp. Only clipping made by the amp. SO after setting the gain with DD1 or Oscope you don't need the clip light. Quote Thinking is the root of all problems... You ALWAYS get what you pay for.
