Interested to see what ppls opinions are on these
the obvious i can see is that 31 band vs 30(EQT),
Time Correction on H700 and dolby etc.
the Alpine does front/rear/sub for eq and phase control as opposed to the EQT only being a left/right with crossover out for sub.
one thing i don't know is the EQT has this constant Q does the alpine have that ?
if you have read the PDF on them (i can email if you like) what it does is went in boosts or cuts a freq it doesn't do a wide cut/boost but fairly narrow... if you get what i mean
also for the price difference does anyone have any arguments as to the audiocontrol being $200 more plus it must be installed by a qualified installer that knows how to read the RTA as audiocontrol would want them to... again if you understand what i mean
more and more i like the alpine unit

they are very different beasts.
the alpine is digital, the audiocontrol analogue. some purists prefer analogue.
the alpine includes dolby digital and 8-channel output with TA on all channels.
the alpine can be used as either 31-band (narrow Q) graphic EQ or as a selectable-Q parametric EQ. i personally prefer parametric EQs, which are easier to tune by ear.
the alpine is designed to mount the control face in the dash for easy adjustment from the seat. the audiocontrol is a set and forget EQ that is usually mounted in the boot, but could be placed anywhere it fits.
the alpine allows digital inputs if you have a matching alpine HU with digital output.
the alpine has full xover adjustment.
there's other differences too.
personally, i love the flexibility and functionality of the alpine. however, you are paying for heaps of features...which may be superfluous for you. so if it's an audiophile EQ you're after, the audiocontrol EQTs are excellent...but you'll need 2 of them.

I understand you can take a optic output from say a 7998 and that goes into the H700. then from that does it go to the control box back to RCAs to the amps or what?
i see what you mean about them being totally different
just downloaded the PDF on the H700
very nice indeed!

i presume the H700 is much the same as other PXA processors.
the 'display' will be a glorified hardwired remote, and probably only a thin unit that fits in your dash. then it will be wired to the main processor unit which can be hidden away.
it's the main unit that has all the terminals/inputs/outputs. so it will have all the digital input terminals, plus all the RCA outputs.
if you place the main unit in the boot, that allows you to use very short RCAs, which is always a good thing in terms of minimising signal loss and degradation.
as i haven't physically seen or used the H700, i only presume the above is the case. the installation .pdf no doubt would shed some light.

i believe RRP is $1499. i haven't visited an alpine dealer in the past few months to know if they're available yet.
hehe how does it benefit sq with one of these EQ's ?
don't some of the higher model Alpine HU's already have Time alignment, crossovers and Eq's ?

the HUs have a more basic setup with fewer adjustments.
the PXA processors offer far more adjustments and more comprehensive features, plus they also use different DACs which are arguably better.
still, the current crop of HUs are pretty good. the ones with 'bass engine pro' have a decent EQ in them, but still a little limited compared with the PXA's.

well i can tell you they have been out for a fair while now and yes rrp $1499.
you would never see these in my local alpine dealer though cos they don't bother getting much if any of that stuff in at all, you would have to pre order it.
thats the problem us tassie guys have we can't just go for a stroll into a one of the local car audio shops and audition whatever we want. cos the fact is we only have got 1 car audio store per city here.. one in burnie, hobart, launceston... besides autobarn you got to an electrical store and get pioneer stuff.
makes decisions pretty hard

download the PDF from www.alpine.com.au
i have never see so many adjustments in one little unit.
stuff paying money for a 7998, may aswell just get a IVA-C800E (incase you don't know its alpines lcd display with all the bells and whistles) pitty it doesn't have optical out from what i can tell

AudioControl also make the DQT:
a DIGITAL 30 band EQ (L/R separately adjustable)
+ 2 parametric settings.
you can also save your settings in one of the 8 user memory slots.
will have an option of dash control coming out in winter...
i had a look at the pxa700 and was told that it introduces a lot of noise into the signal. if money is no object check out the audiocontrol dqt or rockford symmetry epx2 (with 28band eq expansion card) and whack on a rockford surround processor.
i was told even though the pxa700 would work fine with non-alpine headunits, that its real power lies with ainet. which i prefer not to go into.
the dqt cost me 1200.

I have had a real good look into this comparison EQL (Audio Control's digital gadget) vs PXA-H700 which from a Alpine HU-user seems just the ticket.
Can't find that .pdf file on the Alpine website tho for the life of me and I WANT ONE!!
For me the control of the thing in the dash and Alpine system auto-compatibilty (even looks the same as the HU) as opposed to the boot of the car where the AudioControl thing would end up is the clincher.
Both seem excellent devices. Orion's DQT thing also looks a good product and looks sexy too.
As for availability, I still haven't found anyone who has a H700.....my understanding was that May is release month ?????

Yes they were officially released but never made it out of the factory...
They had to be re-chipped for the Dolby Pro logicII as it was putting out subsonic frequencies that were unacceptable in the world of Car Audio(fine for home gear)
Dolby labratories had to design a chip specifically for Alpine with new filters

I just checked the Alpine site at
www.alpine1.com and the PXA-H700 specs and owners manual are now available there, under processors....it appears that signal to noise with digital optical input is 110 dB, but there is no mention of what it will be with regular rca analogue in...haven't DL'd the manual yet maybe it says in there..

Well the Alpine U.S. site says release is set for June 2003.
Thanks islandphile, got the .pdf file there, haven't really looked at it tho yet.
Looks a MAD product

Be sure you really NEED any EQ before adding one.
$1500 can buy awesome speakers!
I see it all the time, guys with $1500 processors and $500 speakers, it doesn't make sense.
Over the years I've built many SQ show winners, one of my favourite systems had a Dynaudio 3 way front, made up out of a 220 (5 and tweet) along with a pair of MW170s. The mids and tweets were in the kicks, with the midbass in the door. Sub bass came from a pair of MTX Black Gold 10s in 0.5 cube sealed fibreglass boxes in the rear quarter panels (next to the back seats). A pair of Black Gold 15s were in the boot floor.
The mid/tweets were actively highpassed at 400hz, the midbass ran 50-400, the 10s ran 40-80 and the 15s were lowpassed at 55Hz.
That car had the best midbass I've ever heard and the sub-bass was strongly focused in the front.
It scored a 37 on the RTA, all without any EQ. Careful crossover selection and level matching, added to excellent speakers meant it didn't need one.
I've yet to be impressed by any of the "wizz bang" digital devices. They tend to be used to cover over problems rather than fix them.
I can't say it often enough, speakers, speakers, speakers it's all about speakers and their install/locations.
