JBL MS-8

http://www.audiogroupforum.com/csforum/sho...ead.php?t=63407

It does true 3.1 for cars, plus add on rears and it will do ambience as well. Logic7 DSP......

Gary Biggs smashed everyone else around the court at Finals using this and the Beemer Idrive.

All for only $800 US.

Ladies and Gentlemen, I think we may have found the next stage of technology.

The JBL MS-8 includes a display, a wireless remote control, a binaural microphone, a setup CD
and an eight-channel amplifier/preamplifier that can be connected to any car’s existing head unit
via speaker- or line-level inputs. The DSP provides signal summing and conditioning that can
reconstruct a flat full-bandwidth stereo signal if the radio does not provide one. At the heart of
the MS-8 is a new, proprietary equalization algorithm that makes achieving contest-winning
sound quality a snap.

nice....

still the stereo sound illusion though...

wonder when these might become available?

(cause I want one...)

Nice find Matt, a very interesting read. Soo tiny too.

Welcome to the age surround sound.
This will be a MAJOR step up for most people. It seeks to address the largest issue in a vehicle, the space.
It also uses a decent algorithm to remove information from the centre channel, so the image does not bleed to somewhere between the centre and outers. Finally a monophonic centre which will show case vocals. :clapping:
The other gain will come from possibly obtaining stereo in a vehicle. (Most people have panned monophonic) This is because it has rear channels to increase acoustic crosstalk, which will allow for the front outers to be at a different azimuth. You may finally have the image beyond you pillars and over the bonnet.
The ambient rears will give far more realism than stereo could hope to achieve. You may actually now prefer to listen to music in your car instead of the home.

You could have it now if you use a car computer.

Because I can.

Told you so. nah nah nah.

sounds like someone got interested... here's been a lot of technology available which never makes it out of the PC-plugin stage.

pity about the "no digital inputs" though.

[Brycestro]

Could someone please explain how this differs from say an Alpine PXA-H701 processor?

It does what all other OEM integration tools do and what every other DSP (EQ, Crossover, Time alignment, 7.1) processors do, but it sounds better, is easier to use, is less expensive and is far more advanced in terms of DSP power. Best of all, it's a tool you can be successful with, rather than a whiz-bang collection of filters and adjustment possibilities that require a PhD in acousitcs to use.

any more than that and I have no idea.

sounds very interesting

i'll be keeping an eye out when building my next car, will be a big project lol

[zion187reigneth]

same as RFosgate 3sixty.2 +- features............cors

[RoVer™]

Is it useful for SPL?


Sounds like an awesome unit.

Its not the same, nowhere near being the same. If it was the same, I wouldnt care so much!!!

Things it can do that other processors do: Xovers, Time Alignment, EQ.

Things it can do that other processors CANNOT do (available for car market): It has a unique centre channel, and unique front left and rights. It also has unique rear channels.

The centre channel is unique in that during the processing of the signal, it takes SHARED information from the left and right inputs (seeing as there are only two) and plays them as a center. It then plays the individual left and right channel MINUS this shared information at a level 6dB lower then the center. This is extremely clever, and has never been done on the Car Audio market before. It also operates not as an on/off between channels, but like a balance control, will bleed the signal (depending on weight of content between channels) throughout the range between the center and the extremities.

This will produce a REAL stereo image using stereo inputs that currently cannot be done by standard processors. Center signals for stereo sound (not discrete 5.1) simply use a sum of the Left and Right at the same attenuated levels. This will, when you think about it, skew a smaller stage and bias the resultant image .

The rear channels also work in a unique manner. They take ONLY the OUT OF PHASE information portrayed in the front left and right channels, and play that back only. Standard inphase signals arrive ONLY from the front, out of phase signals arrive out of the rear. This will give the perception of a REAL stage, with ambiance and boundaries outside the vehicle.

And above all, it works in real-time, and the setup is done by the unit itself, not the installer.

Now do you think its cool?!?!

hate to burst bubbles - but Dolby ProLogic has been doing that for years.
It uses vector maths to extract the centre channel from the stereo mix, and then pass-through the non-centre channel info to the other two channels.

out-of-phase info (ambience) is decoded, and either maintains stereo (ProLogic II) or combines to mono (ProLogic I) to make the rear channel info.

the problem is that no car processor has true Pro Logic decoding (which is a pity)

[TEGBOY]

Guys your missing the big picture here. This one unit can do processing and amplication in 1 unit. Imagine the space savings.

Albeit not a great deal of power, but a great start in the right direction.

Mum's McIntosh based Liberty would benifit from this system. I miss her old X5, that had decent system. The Liberty, is no where as good.

I've seen some discussion about this unit on another forum and one of the other advantages is the fact that this unit does it ALL by itself you position the mics it plays it test sounds etc..and its done and you can just fine tune the EQ a bit from there and unlike previous attempts of self tuning setups this one apparently not only works but sounds good aswell, and sure there has been stuff that could do this for years in the HOME but this is a first for a car, and before you mention Carputers, yes there is software that can do this but they can from what i've read take a lot of time (and if you don't know what your doing you have no hope) to get anywhere near as good as what the JBL unit achieves in minutes. Plus a carputer can cost alot to setup plus I imagine software that can do these sort of algorithms would not be cheap either. Put simply the JBL processor is an amazing piece of equipment that is useable and accessible for everyone not just those with the know-how and ability to build and setup a carputer, and is a HUGE step forward for car audio.
