using I-Ta / DSO 3D /HDEQ tuning on headunit
i picked up a Sony CDX-GT705DX, which has a good amount of options...
some of them are I-Ta ("Sets a pricise delay for sound to reach the listener from the car speaker")
i dont think i will be needing this... has anyone used this feature on their headunits?
the next one is DSO 3D which is the "Heigth, Width, Depth, of your virtual sound stage"... now this option im not to sure of... what would this be used for? do i have any application for it?
next question is the HDEQ... "Adjustable from 63 Hz to 16 kHz in 13 bands" ... i know i will be using a high-pass from 80hz for my components... but im not sure on the rest of the EQ... would i just go through to see which sounds best... is there a usual EQ guide for specific speakers like which range of freq. is best suited for it? or do you always have to go through manually and find it out yourself...
ok last quesiton... i want to be able to use all these features without affecting the substage... does that mean i have to run seperate RCA's from the headunit to each amp? before with my entry/mid level headunits ive just used 1 rca to run back, then used TIFF 4' rca's to connect the amp's together ... i assume if i did this with this headunit , whichever settings i used on the headunit would also affect the substage considering say i used 80hz cutoff, it would also cutoff the sub @ 80hz since its the same "Front" rca output...
