Fric Epic-urious build thread! People have cried...

Not to belay the obvious, but take the balance one click to the left and call it a day for a while.

If that moves the meat over then use a shallower slope on the door speaker to compensate for the off-axis response.

You are not in a symmetrical environment, no need for symmetrical crossovers. Make sure your absolute phase/polarity remains somewhat constant.

And if you have to go for big over a kliller center.. go for big, you have to drive it, have fun. Make sure your absolute phase/polarity remains somewhat constant.

Well I did click it over 3 notches to the left this morning. The center focal a still pull right of the center a bit. If I fudge the balance much more then the left channel becomes noticeably louder than the right. I believe I'm running the door speakers up to 500 with a 12db slope. When I did that my stage got a lot wider. But the more listening time I get, the more I realize it's not that wide and my stage is from about 11:00-2:00

I'm really enjoying it! I need to get a line driver because the output voltage is kinda low. But other than that, in happy!

Let's work on some gain structure. 2V will do it if you do it right.

I wanted to try them but I run at +4dB in the shop... Did a behringer DCX2496, then swapped it out for a Shure P4800. Both being cheaper than the MiniDSP and the shit to homebrew a balanced +4 output.

And the Shure is 4 in, 8 out.

Well I'm probably not getting 2v with all my eq bands set level on the mini and on the HU. When I first hooked everything up I maxed the gains on the midbass channels and heard no signs of distortion and that was with the Pio HU on 60 of 62. I don't wanna have to crank the HU up that high every time a quiet MP3 plays or when I want to wang out.

Full bore is full bore, get used to a linear volume control, 12dB of overlap over the course of the gain stages will make it right.

You do the math.

I'm not sure what you're getting at, but sounds like you're suggested a broader overlap of frequencies played by multiple channels will give a net gain in volume?

Why not just overlap crossover points and play all my speakers in a whatever bandwidths they are capable and let the eq clean up the mess?

[benny]

nah, he means turn the gain up

[Fricasseekid]

Well hell, they are set @ 3/4! Full gains makes me feel like I'm running out of head room.

Do you have access to an O-scope so you can test the amp at full-tilt?

[Fricasseekid]

Funny pic!


I do and I will!

What's with the new avatar?

[chad]

The gain does not do anything other than determine WHEN the amp makes full power.... If you can do it without sacrificing your noise floor then turn them up.
