You can download the control app and get a feel for it. I was very intrigued by it, but for its price i decided to go a different route.

Thanks.

I’m intrigued by your choice to go elsewhere based on price - dollar for dollar it seems hard to beat. 5 channels of amplification plus Helix Mini with comparative features is more expensive here. What route did you take?

Not when you choose to go with older class a/b amps and you already have a good dsp. If i were starting from zero it would make sense for me, but I am not.

Hi,
Just recieved this amp.....it's TINY!
manual really sucks though...

It is very unclear if the parallel mode is only for 2ohm loads, or to double up power.
anybody know if you can use he software with a measuring mic?

wonder if you can:


1) go Pioneer 80prs into this unit with 4 outputs summed to 8 channel output on the amp

2) go parralel on 4 of the 8 channels to make the amp a 6 channel amp ,this will gain us 200rms to 2 channels (woofers), 100rms (midrange), 100rms (tweeter)


3) now that we have used all 8 channels on the amp one might think hey we are stuck with just 3 speakers what do we do with the sub?

well since we used only 4 channels out from the 80prs we still have the freedom of 2 channels out from the 80prs.

we also have time alignment aswell as a very detailed eq so everything you need especially for such low frequencies right?



this amp can be found for 650 euros in many european countries and a 80prs for 250 euros total 900 euros which is still a few hundred euros cheaper then the Helix P six not to mention it also offers usb in for free whereas with helix you need hec usb which is also extra.



I would love to see a scanspeak 3 way on this unit with the mentioned configuration

manual, also in english

1) I was confused at first, but now get it 6 way front

2) yes, but max 4 channels can do parallel

3) you want to use the internal amp on the pioneer to power subs?


slightly confused from holland...

For a BMW install I was wondering whether to get this or to go for a Match or Helix which is more expensive but has the Real Center processing.

Even though this alpine does attract I would without a doubt go Match especially if you are talking about the BMW specific model.

It really does perform well worth its price

let me make it more clear, we need Left and Right independent EQ , lots of processing capabilities for a top notch SQ system correct?

this also applies for the Subwoofer channel , maybe not so much the L/R eq but eq on a few frequencies non the less and not just 60 or 80hz like %99 of the head units out there.



now back on topic.


1) this alpine either works 8 channels or 6 channels (without bridging) and you use channels 7-8 as a preout to a second mono amp for a stronger sub


2) In my theory you bridge this amp for more output (200rms to midwoofers), use the remaining 4 channels to power midrange and tweeters.


3) In my theory we are left without more channels to consume on this alpine amp meaning no more channels even with a second mono amp to power or dsp tune a subwoofer correct?


well to overcome that you simply take a Pioneer 80prs take 2 of its outputs into this alpine amp,sum it internally on the alpine for 8 output and leave the extra 2 channels output on the 80prs for a additional mono amp for subs.


this means you can still,

a) time align with 80prs
b) phase align with 80prs
c) eq tune with 80prs from 20hz,31.5,50,80,125 hz so a very detailed eq for subs which cant be found on any regular single,double din



so lets assume the mono is a alpine pdx m12 all in all we have a :


1) 1200rms sub
2) 200rms midwoofer
3) 100rms midrange
4) 100rms tweeter
5) awesome head unit with great DAC's that can read FLAC etc


all this with just 2 amps that fit underseats

I know this is old but I wish this could be made into a sticky for a how thread and review cuz I'm really looking into getting one
