Yzf7steve Posted March 24, 2014 Report Share Posted March 24, 2014 So a few years ago I borrowed a friends O-scope from the lab. Found my max volume on my Pioneer 5900 to be 52, 53 squared the wave off. I then set my gains with everything flat with a 40hz 0db track and 1000hz 0db track. A couple of months ago I purchased the DD-1 and got right to trying it out. I plugged it in to the RCA's from the deck made sure all crossovers were all the way up again and all eq's and boosts were flat and off. The pioneer maxes out at 62 on the volume. The DD-1 didn't even detect signal until I was in the mid 30's and when I turned up the volume it went all the way to 62 with no distortion light. Suspicious that the light might not be functioning I turned the EQ up until finally it did come on. So on both the 40hz 0db and 1000hz 0db tracks the DD-1 showed not even a flicker all the way up to 62. So I'm a little concerned as I said the O-scope showed clipping at 52 but DD-1 is saying I'm good to go up to 62. How is that possible? Any help or advise on this would be great! I mean if it's good to 62, which is where I have everything set now, then I'm cool with that but in all the videos I've seen comparing the DD-1 to an O-scope when the wave on the scope squares off the DD-1 is lighting up. So just confused and concerned. Thanks in advance for any help or advise.

boostin302 Posted March 24, 2014 Report Share Posted March 24, 2014 where you using the same 40hz and 1k hz 0db tracks as you did a few years ago? or the one supplied with the DD-1? Its possiable that the tracks you used a few years ago, weren't true to what they were suppose to be. ( correct me if i'm wrong) also, Could the headunit slowly lose its preformance over time?

Yzf7steve Posted March 24, 2014 Author Report Share Posted March 24, 2014 They were different tones. Never thought there would be a difference but that could account for it. I don't have access to the scope anymore to compare with the DD-1 Tracks.

soundstream15 Posted March 25, 2014 Report Share Posted March 25, 2014 Just go by the dd-1 and don't worry, those tracks you used where off or something. Quote Link to comment Share on other sites More sharing options...
will77530 Posted March 25, 2014 Report Share Posted March 25, 2014 we have done dd-1 and o-scope side by side test probably 10 times an every single time it has been right on Quote Link to comment Share on other sites More sharing options...
mothra Posted March 25, 2014 Report Share Posted March 25, 2014 Try connecting to a different channel. I constantly run into an issue with the DD1 being temperamental about which channel I have it on or if I use the RCA instead of the harness. I have seen it not do anything on channel one but work just fine on channel two.

Yzf7steve Posted March 25, 2014 Author Report Share Posted March 25, 2014 When the weather warms up here again I will run it again just to be sure. I mean it sounds fantastic and I've read other guys with pioneers getting full volume without distortion. I was just curious how the 0-scope and the dd-1 could be so far off. But yeah I think the tracks I used originally I got from like a THX sound cd that had a tone of tones on it.

But, I know you never know what level of stupid your dealing with when people are asking questions. :-) Quote 2005 Ford Five Hundred 1 EMF Banhammer 15" Orion XTR 4000.1 Alpine MRP-F300 4 channel Pioneer AVH-X3800BT Link to comment Share on other sites More sharing options...
