Hi Everyone,

I am still around for those who think I have fallen off the planet.

With the PXA-H510 it has parametric eq of 4 bands for the front and rear speakers, and two for the center speaker.

To adjust these "properly" this should be done with a RTA, right? Or does anyone have a better idea? I think I am going deaf and I want the best SQ but also not spend too much on it.

Should I also adjust the Time Correction before doing the parametric eq as well?

Sorry for all the questions, I have never used one of these before, and managed to score one for under $200 but don't know how to set it up properly.

Thanks in advance,

Des.

in theory no man, you should not have to use an rta to tune the processor ... however i would ...

i would also do the time correction first, cause why the rta is usefull in gaining a response curve that you want, the time correction does alter the way speakers image etc, so you could set the system up, and then find it dont sound right once you done time correction

TA should be used as the last resort. set it up as well as you can without using EQ... then find a RTA to use to find out what the freq curve looks like.

then use the parametric eq to flatten any peaks. you shouldn't boost frequencies when using an EQ. can introduce clipping into the line b4 it gets to your amps.

once all that is done then jump in the car and use the TA if you need to. it might be good enough that you don't need to.

An RTA can be useful to help find the lows and highs in the freq range of your car...but who wants to listen to dead flat response?
Everybody hears music differently and every one has different taste,so tuning it flat may not be the best for you.
But it does help to tune it flat and tweek it from there to your liking

As far as time correction goes...measure the distance from each spk to your listening point(ie:drivers headrest)then go to Alpine.com.au Enter the "i-personalise" section, enter in the measurements in the T/A section and it will calculate the settings for you
Have fun
