DD-1 -5 or 0

[MIKE-2U]

just got my dd-1 and cc-1 combo in today. I noticed 40 hz 0 db and 40 hz -5db . whats the difference and how do i know which one to use. also when i set my highs and mids amp say the max is 34/40 and the sub amp is 36/40, does that make my max volume 34 ?

[MrSkippyJ]

it's a shame they didn't put the instruction manual in your DD-1, it explains all of that there!

[MIKE-2U]

they do . i just read it and couldn't find any of that.

Really? It says in the manual to set it to the lower number.

Use the 0db tracks for the head unit and the -5db track for your amps.

this is the difference

0dB for headunit/least distortion

-5dB for amp gains/sq setting << what i use

-10dB for amp gain/compromise << what most use

-15dB for amp gain/spl setting << too quiet for rap music

max would be volume 34 in this case

"-15 too quiet for rap music"? i find a break in your logic here. tuning with -15dB (track 7) at the head unit and using a dd1, would mean that your turning your amp up higher before getting distortion, so obviously when you play a regular cd it will be louder than if it was tuned with -5 (track 3) or -10 (track 5). what would be too quiet would be tuning with track 3. that is unless your going strictly for quality but i like my shit pounding loud.

You never use -15dB for the headunit, you always use 0dB to get the cleanest highest voltage possible. Rap music bass is louder than -15dB, thus anything louder than the tone used to set the dd-1 on sub amp will push the amp into clipping. Most rap music is between -5dB and -10dB, so using -15dB means most of the time you are +5dB into clipping. There is no break in logic besides yours.

Yes I agree you only use 0dB to find your max volume. when I said "at the head unit" I meant which track I'm playin to set amp gains only. I get what your saying though but in your OP you said -15dB is too quiet for rap - now are we talking about what rap actually plays at or are we talking about setting gains with dd1? If we're talking about setting gains then the -15dB track would cause it to be too loud, as you stated as being +5dB correct?

[Decaf]

Correct, if you play loud rap setting gain with -15dB tone will cause clipping. Using the -15dB tone will have the gain in the closest position to max gain compared to using -5/-10 which are safer and closer to the loudness of the rap music being played
