Global settings, EQ and time alignment
 
Google translator used

Hello

When I installed my Pioneer avh-z9200dab, I did not do any tinkering on the time alignment.

The scene of a quality system is the one that identifies the voice in the center of the dashboard and the rest of the instruments placed each one in the part that corresponds to it according to the recording.

I would like to know of those of you who have an aftermarket radio unit, what has been your time alignment configuration, what parameters, what cuts and frequencies you have used.
It is just for reference.

I will also receive the Pioneer cd-mc20 automatic calibration microphone shortly, so I can compare.

My intention is to achieve a sound as faithful as possible.

My doors are soundproof.

I am currently using 2 French brand amplifiers: Blam ra754d and Blam ra251d.

Thank you

Unfortunately, there is no "one size fits all" setting in car audio. Every system is different and you have to deal with every variable by making adjustments which will affect each other in numerous ways. What works for a 2020 Hakone Edition 86 with stock speakers will not work the same on a 2013 BRZ with aftermarket components and two 10 inch subwoofers.

I would recommend you start here and read all of the articles that Andy Wehmeyer has written on his several subjects that he discusses.

These are very informative and well written articles.

Thanks.

Here anyway if there was someone who has done a configuration with the radio to get the voice centered it would be appreciated. As a guide I can do tests based on the configurations that some users have set.

First thing to do is make sure all of your speakers are in phase with each other, meaning that they all push out and pull in at the same time. Correct any wiring mistakes now before you continue reading. If just one of your speakers is out of phase (with the occasional exception of a tweeter) it will mess everything up.

Next thing to do is answer the questions below:

1) How many speakers are you using in this system?

2) What types of speakers are you using in this system?

3) Where are each of the above speakers placed in the vehicle?

4) Are you wanting to use the head units' Standard Mode or its Network Mode?

Answer those questions and I'll try to get back with you as soon as possible.

Hi

1 2tweeter + 2 woofer, 2 woofer 4" rear OEM panels, 1 subwoofer.

2 set of OEM audio +, 1" tweeter, 6,5" woofer, 4" rear, 8" sub.

3 OEM and sub in a OEM audio + box.

4 I'm using standard.

So, you have speakers in all of the OEM locations plus a subwoofer. Got it. In Standard Mode, the speakers are set up as front left and right, rear left and right, and subwoofer left and right. Keep that in mind.

Couple more questions:

1) Are you using the factory amplifier for the door speakers?

2) How many channels of amplification will you be using in your system?

3) Are you planning to use the head unit to power any of your speakers?

EDIT: I can already see that you're going to have problems trying to get the time alignment to work properly.

thanks for your time.

I don't think you understood me, maybe because of the translations.

my speaker system is OEM audio plus, but the amplifiers are blam brand, both amplifiers connected by RCA / low, all this connected to my Pioneer, there is no speaker powered by the amplifier of the radio. so all the front, rear and subwoofer channels are separated.

front cut-off: 100Hz -24db
cut back: 125Hz -24db
subwoofer cutoff: 100Hz
-24db

EQ

80Hz +1
125Hz +2
200Hz +1
315Hz +1
1.25k -1
2k -1
3.15k -1
12.5k +1

sound improve: lvl1

he's saying that to do time alignment correctly, you would need to separate all of the speakers. right now, the tweeters and 6.5" woofers are connected together, which makes it impossible to do any accurate time alignment

Ah ok. So but this functions work with standard mode.

Yes, what @soundman98 said.

However, you might get it to work if you use Network Mode instead, and lose the rear speakers from the system by running the high channels of the Pioneer head unit to feed the signal to the amp for the dash speakers, the low channels of the head unit to feed the signal to the amp for the door speakers, and the sub channels of the head unit to feed the signal to the amp that runs your subwoofer.

Your rear speakers in this case will drastically hurt the sound quality of the front stage that you are trying to create.

So why does OEM audio plus prefer to use the rear speakers? in fact when I had it working the scene was well executed.

Because the stock BRZ/86 system is what the people who designed the OEM Audio+ system were given to work with. Pioneer doesn’t know what you’re installing their head unit into, but they DO know how their DSP works. Trust me on this, if you’re going for sound quality, the fewer speakers, the better.

Oem audio expects you to use the factory radio, use their amp, and contact them for any further tuning.

Once you ditched the factory radio, you're on your own as far as tuning goes, and you're even further on your own once you selected a different brand of amp.
