How to set gains with DD-1 when a MS-8 is thrown in the mix?

[_Nomad_]

I just got my new DD-1 and I have to admit, I'm a total noob with it.

I'll give you my setup so you have all the info for my question.

I have a Kenwood DNX890HD head unit that goes to a JBL MS-8 signal processor which goes to a JL Audio HD900/5 amp.

Now, I "think" I understand how to set the HU and amp, with emphasis on the word, think. But how do I set the gain with the JBL MS-8? I know you have to gain set every component in line from the HU to the amp. I saw the video on setting gains on a line driver, but that is different from a MS-8.

Any help would be appreciated. Thanks.

Ms8 is a max output voltage of 2.8v

So set h/u with dd1 then do the jbl setup then sent the amps gain do jbl setup again to make sure

And set gains one more time for adjustment

That's how I would do it

-0db tone on HU. Then -0db tone on processor. Then whatever track you need for the sub amp

So I would set the HU with the DD-1.

Then do a MS-8 system setup without the gains set on the amp yet.

Then I would set the gains on the amp with the DD-1.

Do another MS-8 system setup.

Then use the DD-1 to set the gains on the HU and amp again?

Is that right?

Ok, so I use the -0db tone for HU, but how do I use it on the MS-8? It has no gain knobs or anything.

See, I told ya I was a noob.

The ms8 will basically do its own setup

So u just have it do its thing then set the gain on the amp do it again so it gets the right measurements then set gain again

Ok, I think I get it. So once again I just do this?

I set the HU with the DD-1.

Then do a MS-8 system setup without the gains set on the amp yet.

Do another MS-8 system setup.

Then use the DD-1 to set the gains on the HU and amp again one last time?

Ya

That is probably the right way

I have one more question. On the instructions of the DD-1 it says to turn the gains all the way down and the crossovers all the way up in order to perform the gain settings. If I'm using the MS-8, do I just disable the crossovers on the amp since the MS-8 will be handling that job, or do I still enable the crossovers on the amp and proceed the way the instructions said to?

Thanks for this help guys!

For my 3Sixty, I turned off all xovers.
