I have bought myny modules from soundimport! Very fast shipping they ship the day you bought if it is before 16 hour.
Absolut no problems so far .But all modules are working i can not sy how good is the warranty!But i think a lot better as from the italien man.
He told me after a module died they must be a peice of copper that makes a short cut.(but i solder not with installked mnodules)
I think he is a liar.I send him the broken module i was sure it was not my fold he said icepower say the problems most comes from outside...
Thanks for the info,
it is evident that some problem has occurred, because to burn a power mosfet in the area that is highlighted in the photo, in my opinion the problem is not due to the power supply, but more likely a problem of another kind has occurred ..
Unfortunately, I do not have the right to decide if the module can be replaced .. if you want I can put you in contact with the ICEPOWER ITALIA product manager; more than that I just don't know how to help you
Looking forward to your further info
Best regards

Forgotten to mark the photo.
(26/42
The speaker outputs are fully overload and short circuit protected. In case of an overload or short circuit event, the module will limit the output power and eventually shut down and resume operation when the overload or short circuit has been removed.
Due to the balanced operation, it is not possible to connect one of the outputs to ground. The module is protected against such an event.
On the 1200AS1, only channel 1 speaker output is mounted.
11.3 AC Mains Input
ICEpower1200AS has a universal mains input operating on all common mains supplies. No switching between low and high mains is required. Additionally, the power supply includes Power Factor Correction complying with international standards.
When power is applied to the 1200AS, the module will after a short initialization read the control inputs and start operating accordingly. If the module controls are left unconnected, the module will start normal operation without further action.
The power up and power down timing is shown in Figure 18 and specific timing values are available in Section 8.4.
Figure 18: Power up timing
The 1200AS is fitted with a fuse on the mains input. In case of a burned fuse, the module is defective and must be replaced.)
And this is what i found in the manual.
It says if the main fuse breaks the module is defective?
But it not says why .....
On the photo you can see the crack of the chip underneath the module in the black circle?
I don,t know this part .For me it seems like a Fet with only 2 legs?
Perhaps somebody has the answer which is the couse of the crack.

In any case, I can start asking if you can contact the ICEPOWER ITALIA manager
As soon as I have information, I'll contact you

Hi Mario,
Let's forget the rumors about the problems that can happen regarding the amplifiers, each amplifier has its own story and how for men it can be lucky or not ..
Having said that, as far as the repair of your module is concerned, I believe that the broken part can be replaced, the problem is that if we do not find the cause it is very likely that the part will continue to break.
What I can do is send it to the company for the necessary checks, and if they authorize me, I can replace the form for you for free (you just have to pay the shipping costs ..)
Let me know what you decide to do
Best regards

Hi Mario,
OK Do not worry..
You can send the form to the following address: STELLA ROBERTO
Via Roma 22
CAO 28844 - Villadossola - VB
ITALY
As soon as I receive it I will try to get a quick assistance, but I warn you that we are in a period of holidays and COVID, therefore I have no idea of the necessary times ..
Best regards
RS
Hi Mario,
Yes, the form has arrived and has already been delivered to my contact person who takes care of ICEPOWER,
We are waiting for an answer ..
As soon as I receive information, I will notify you
Best regards
RS
Hi Mario,
Finally I received an answer from ICEPOWER and I am very sorry to inform you that after their careful analysis, I found that the failure occurred for reasons not deriving from the module (external reasons) for this reason they do not recognize the free replacement.
What I have been able to do is ask for a new module at half price and I am waiting for their response
I hope they agree to this solution to try and help you ..
As soon as I have news, I'll contact you
Best regards
RS
Hi Mario,
Difficult to have all the answers ..
The things I can tell you are the following,
As for the module problem, I think it is due to a power surge in the network that somehow created a power failure, and since there were 2 modules, probably one of the 2 saved himself by sacrificing the other ..
As for the temperature, the operation of these modules generates temperatures that are not related to the power supplied, but are a function of the switching of the power supply, in fact most of the heat is due to the power supply but not to the power supply, in fact once you reach the operating temperature of about 40-50 degrees, the heat remains constant even without asking for a lot of power (but even at maximum power the temperature varies a little ..)
The listening differences of the different modules is not recognizable in quality, but rather in dynamics, given the difference in power, the dynamics of a 300asc and a 700as1-2 or a 1200as1-2 is in dynamics (with the same speakers. )
I can tell you that during some tests, we also found that for example the 1200as2 module had a more pleasant result than the "dual mono" which used 2 1200as1 modules ..
As I have already written to you, I asked to be able to give you a 1200as1 module at half the price, and in this regard I have confirmed that I agree.
This means that with around 220 € you can have a new 1200as1 module
You must confirm your willingness to proceed with this formula
Otherwise you could get a considerable discount if you decide to buy a different module (700as1-2 etc.)
Waiting for your reply, thank you for your cooperation.
Best regards

Ok understand.Is there an idea what can be this external reason?To avoid them for future?
I have the idea the 1200 AS1 is an Diva.... not very robust at all .
Seems the 700 and 300 modules are imun to this external reasons .And the pascal modules are imun too.
Could it bee problems with the 230 Volt?or problems with the ground earthing?
it should be protectetd. but i heard last not all protection features on some modules are 100 % fail safe ?
I read an 300 ASc will crack if one speakeroutput is be shortetd to ground.but ists not sure it will crack.
replaycing broken part on the module is not possible?Or are there more parts broken?
if not asking for rabatt is good idea thanks.
On the other side im thinking of using on my other speakers 300 and 700 or 125 asx2(btl) where i do not need so much power.(of course this one 1200 i think is have to replace with an 1200)
On hifi speaker at all i dont think i must use more 1200 modules than nessecary.
But i read they would sound much more better than 300 or 700 modules......
But i can hear no difference ? on situations i only need 50 or 100 watt .
For example i tried an 300 ASC on Klipsch RP6000 (for sourround) .one ASC module for one RP6000 not ASC AS combi power sharing.
I found that even at full power the 300 ASc never took more than 50 Watt out of the wall power.And at idle the 300 only needs 11 watt.
At this time i use on pascal S-pro 2 on the RP6000 , but one module for both speakers.normaly i go mono but i dont hear a difference...
https://www.amazon.de/gp/product/B00J8LB3ZI/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
inside the sta1000 is only one s-pro 2 .cheap and no problems with warranty but very very ugly . and if you open the warranty is gone i think.
there seems no way for buying pascal modules .....
But what i will say , i hear no difference.
so what i will say it seems using much more power than will be needed seems not to make sense.
The big modules get hotter and need much more idle power and the benefit is?
An 300 ASc has an continius power 100 watt at 25 degree.
The Rp6000 needs 3Amp and 10 Volt for 106 db (its the max db ....) .
So i am not sure if i bee on the right way....
Speakers with bad sensitive of course need more power .
