dd1 help

[gabe]

okay i just bought the dd1 a few days ago and i had couple quick questions. When tunning the amp should i use cd test track or downloaded versions on phone via bluetooth. honestly i dont listen to cds im either pluged into aux usb or bluetooth does that mean i should tune my amps while playing the track on my phone using aux usb or bluetooth or does it not matter its all them same???

reason i ask is because aux usb and bluetooth are considerably louder than cd

i have pioneer 4800 bhs

If that's what you use then maybe rip them to your computer as a wma file. That way you can check the distortion of your phone.

do you think playing it from usb bluetooth or aux will make a differnce in where the gain is set? actually dumb question ill figure it out by using volt meter thats how i tuned my system before the dd1 i can check tunning with cd and see volts then tunning with aux and checking volt

[RooTxBeeR]

Yes, there will be differences, or at least should. In the different forms of signal transfer. Which ever you use to play your music the most, tune through that method of signal transfer. I tuned with my aux cable, now I am using bluetooth, everything seems to be a tad louder, as well I can smell my subs every so often now, so I will be retuning with bluetooth.

another question how is track 5 have more bass than track 1 i fee like 0db much more and than -10db

[ShadeTreeMechanic]

The higher track level will cause the distortion point to be found sooner as you adjust the gain, causing a lower gain setting. The lower track level will allow the gain to be turned higher before distortion is found.

This is exactly what I did for the DD-1. I always use my iPod so I put the tones from the CD on it and tuned accordingly.

i still dont see how track 5 which is 40hz @ -10db is louder than track 1 40hz@ 0db track 1 sounds way louder when playing

[MrSkippyJ]

it is louder when playing (0db that is). it's why your gain would be set lower on -10db.

the lower db settings are simulating musical averages. 0db is the loudest recording setting. All the way up. However we all listen to music and know that not everything is recorded at that volume. Sometimes its recorded lower, the lower db settings on the CD are guesses to what that average will be.

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.
