Where`s the Parametric?

Grumble

there are 30 bands of parametric for each output. There are 8 inputs and 10 outputs. You can adjust each output individually- or group them (for front stage, rear fill) and adjust accordingly. Same with the 24db/octave crossovers - so it makes it easy to run all components active.

They're supposed to be shipping a "smaller" version soon (DM-608) which has 6 inputs and 8 outputs with all of the same features.

It's a very cool unit.

After further reading my manual - there are:

The DM-608/DM-810 features a graphic EQ with a few twists: 1. Modes a. 30 band mode: 30 bands of 1/3rd octave EQ b. 10 band mode: 10 bands of 1 octave EQ c. 14 band mode: a mix of 1/3rd octave EQ in the bass region and 1 octave EQ in the midrange and treble regions.

Oh ok and thanks for the info.

Audio Control really needs to improve the owners manual for this unit on their website because they do a really poor job of explaining all of the features of this DSP.

I`m going with the JL TwK and the new PAC piece.

The EQ curve the ACM puts out its not noticeable... I think it helps when you listen at low levels you need a bit more output from the sub and at very high levels you want to tame the highs a bit...

James Cole

I wanted to to do something similar to yours but had some old equipment from my old install that I prefer to save some money and use it...

My first choice was Carbon C8 + C3X front stage, Lucent L6C for rear and C10XL.

Went with Hertz Mille Legend front, Lucent L6C rear and C10XL.

For amps I purchased the Mosconi AS100.4 for active front stage and center, rear and subs is being ran by JL Audio HD900/5

I also have an old audison Bit One but it makes some strange noises some times, next week a Mosconi 8to12 should be installed to take care of that.

Originally we started with the OEM Sony sound system, we reprogrammed for low level output and de-equalization (thanks to LIVNITUP & DanMC85). We did a quick little test with a speaker and were getting all sync 3 voice commands from the low level outputs without any other mods to the wiring, we chose to get the low level outputs from behind of the truck where they went to the OEM Sony amp.

As you can see OEM Amp and sub are completely off the vehicle and not needed anymore, if this could not be done there´s no way in hell I would venture to add a system feeding of the Sony amp it would be terrible.



















The SQ is excellent, all chimes work well (maybe a little lower in volume especially PDC) Noise floor is not audible with vehicle running and it will be lower with the 8to12...

I think the ACM reprogram is the best solution by far because you keep it simple and with less devices on the chain which is always good.

Very happy with the result, normally when taking the OEM signal to a new system is very complicated and the SQ is well... not up there like an aftermarket deck. With this mod I can surely say this is like adding an aftermarket deck without any of the downsides.

There are more OEM EQ options under forscan... maybe we just haven't found the option that is truly flat at all volumes but with the current option selected thanks to Livntup & DanMC85 to me is perfect and not noticeable at all!

That's what I'm thinking as well. A guy on DIYMA was able to post up some measurements from his Ford Escape ACM and I came to mostly the same conclusion. The high end roll off starts at 15K which most people won't be able to hear anyway. The low end though runs up to 100 Hz which could be kinda problematic. It actually doesn't roll off the bass. It attenuates everything from 100 Hz and up by like 30 db at the lowest volume and then as you raise the volume, everything else comes up while 20-100 Hz stays the same so when you're at near max volume, the mids and highs have caught up with the 20-100 Hz range.

80-100 Hz is getting into the boomy part of the sub bass and can be an area that you don't want accented. Every car I've ever tuned, 80 Hz is where I start cutting. I plan on getting back into MECA SQ competitions with this system so that would be a problem for me. All those stand up bass tracks on the judging disc, that 80-100 Hz range would boom like crazy. But that's what the JL Audio Fix should hopefully cure. I figure mounting the remote volume control just behind the gear shifter would be the best place. My arm is resting on the center console 90% of the time and my fingers are dangling right there anyway so it would be just as convenient, actually a little more so than using the steering wheel controls. The only thing I really use them for anyways is the Mute function which would still work.

James Cole

You should definitely try and see, I remember reading a post from someone who did this mod and competed as well for SQ, he used the DRC volume just to be safe when being judged but he said he couldn't really tell a difference from cranking the OEM volume or the DRC volume.

As for the "boomines" its simply not there, maybe the ACM has changed (DIYMA guy did not have Sony) and there is also other Forscan EQs setting I have not experimented with because I see no need. I get clean and tight bass at all volumes and I do tune my systems to around 80hz as well.

_MacLeod_

That's good to know. Maybe once I get everything installed, I'll hold off on permanently installing the DRC and just use the factory remote instead and see how that works. If the Fix isn't having to de-EQ anything, it'll still be valuable for boosting the input signal and sending it out optically to the processor. I don't have first hand knowledge yet but word is, the noise floor is exceptionally low with the Fix. That's the main thing I'm trying to get around, the hiss associated with running speaker level inputs. Way too many quiet tracks on the judging disc for a steady hissssssssssss to be acceptable.

James Cole

My hiss right now is barely and I mean BARELY audible with the truck off inside my garage, truck on is not possible to hear it.

With the 8to12 8v I think I will make it at least 50% less which is truly low, the main reason for using the 8to12 is not the hiss is some other stuff, but right now the hiss to me is not noticeable even when cranking the volume and passing "quiet" parts in a track.

_MacLeod_

OK, I know this Forscan thing has been out there a while but for some reason you've just now piqued my interest in it. I'm trying to find stuff to read about it just now so let me see if I've got this figured out. Buying one of tools, I can use Forscan to turn off the EQ from the ACM? I get the part about turning the stock speaker outputs to low level outputs but we're still back to the hiss issue. What I'm wondering is, according to that thread, you can keep the stock speaker wires as high level and just turn off the EQ, then I could run that to the Fix to boost the signal and send it optically to my Twk processor....right?

If so, I think that might be the best option for me since I already spent the $300 on the Fix. That should theoretically give me a noise free signal to my processor and let me use all the stock volume controls without any variable EQ. If I didn't have the Fix, I think you're right that this is the best option for somebody to go as it only costs the $80 investment on the OBDLink tool which can be used for SO much more down the road. Seems like a no-brainer if it's that easy.

One question, this line from the Fusion forum:
WTF?? OK, I thought all you need was an OBDLink tool and Forscan. Now this post is saying you have to buy some code to enable this option? That makes no sense.
