rocknwoo Posted May 26, 2010 Report Share Posted May 26, 2010 i have a kenwood ddx812 hu and just set the volume with 1KHz 0dB on my oscope at the RCA. My HU doesnt clip at full volume(35/35), my question is even though it doesnt clip at 35/35, is it wise to set the rest of the system(amp,processor,etc..) and play music at that volume. Even though not clipping ,would s/n rise at that volume? Thank in advance Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted May 26, 2010 Report Share Posted May 26, 2010 check it again at 50hz and 100hz. i havnt tested a hu but i have found that an unclipped signal at 1khz doesnt mean an unclipped signal at a lower frequency, when i scoped an amp. i have a video on here of that if you want to see what im talking about.

rocknwoo Posted May 26, 2010 Author Report Share Posted May 26, 2010 Thanks I will try that but if it doesn't is it still ok to set the rest of the system and play music at that volume Quote Link to comment Share on other sites More sharing options...

skittlesRgood Posted May 26, 2010 Report Share Posted May 26, 2010 ya thats why i added 100hz. incase the hu was crossing over any lows. let me know what happens. if the hu isnt clipping then its all good. only reason i wouldnt do it is if a song comes along that was recorded at a lower volume then you cant turn it up any more. tuning with the volume a little lower could give you room to play around but thats all up to you.

bobonit Posted May 26, 2010 Report Share Posted May 26, 2010 Since you know that you are not clipping at the HU, you need to go to the next item inline (eq,crossover, etc...) and check the signal with the oscope. If you get all the way to your amps with no clipping, then you adjust the gains in your amp until the output clips, then back it down till its unclipped again. Steve has a video tutorial in the videos section where he shows checking the HU, then the amp.

rocknwoo Posted May 26, 2010 Author Report Share Posted May 26, 2010 I got a little busy but I will try it thanks again Quote Link to comment Share on other sites More sharing options...
rocknwoo Posted May 26, 2010 Author Report Share Posted May 26, 2010 Cool I will be doing that but my main question is even though it's not clipping would you get more noise in your system at that volume? Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted May 26, 2010 Report Share Posted May 26, 2010 Cool I will be doing that but my main question is even though it's not clipping would you get more noise in your system at that volume? only you can tell that. some hu's will have static the more you turn it up and some wont. just press pause and turn the volume up, see what happens.

rocknwoo Posted May 26, 2010 Author Report Share Posted May 26, 2010 I see as long as the noise is down at full volume and not clipping it's all good thanks for clearing it up for me SkittlesRgood Quote Link to comment Share on other sites More sharing options...
