TOPIC: New plate amplifier, New forum section

@ Snugman,

Unfortunately Acourate is expecting too many taps whenever it's building its FIR structure... We'd have to look at something else that is a bit more "resource" friendly.

AFAIK you can window and truncate the impulse response in Acourate before exporting it. Thus it should probably work. I'd recommend to take a look at rephase too. It's completely "manual" (no automatic inversion of impulse response) but thats the trick

regards, Daniel

@curryman
thanks for the rephase hint. I was not aware so far.

@all
I found out from Uli Brueggeman that acourate can build filters for the DRC series, so there should be a way for the PWR-ICE as well. I will find out once the plugin is ready.

Regards

Hello,

We are testing the ice plate amp for a special project and i have few questions:

- is the 250asx2 version will be available soon?
- what is the most popular solution to seal the enclosure from the module (plateamp is leaking badly)
- let's say i want to use one plateamp per side, how do i connect them if the source is analog (is the daisy chain works?)

Thank you

Jon

I don't know about most popular, but FWIW I built a separate sub-enclosure into the Mini Convertibles - www.hifizine.com/2013/09/the-mini-conver...-loudspeaker-design/

Here's a cross-section to illustrate:



I'm not sure I quite understand. If you are using analog, use a Y-splitter. The daisy chain is for the digital signal.

Hello John,
Thank you for the reply it's well appreciated.

So there is no ''easy'' solution to seal the plate amp, am i right ? No ABS injected mold that is cheap and not volume-consumming

About the daisy chain aes-ebu, i was secretely hoping that would work with the analog input as well (i.e. analog input, then converted in digital, then before any DSP to the aes-ebu output...) but it's not. So it makes things more difficult i guess

finally, any news about the 250asx2 version ?

Hi again,

If you're making the box, it's easy enough to build a sub-enclosure at the same time. Maybe you're trying to do something else, modify something already existing?

?? If your source is analogue just run analogue cables... The digital link makes sense if your source is digital... It's confusing what you are trying to do

Haven't seen anything about it in a while, perhaps devteam will be along to give an update.

i was looking for simple and clean solutions (read: not DIY-ish)

Looks like the 250 one is out. Unfortunately, no news about OSX software or a firmware update for auto on/standby.

@ DS1, we haven't had a chance to look into the OSX version since this is a complete new requirements in terms of connectivity compared to a USB product (supported on Mac/Win). I guess that over time, as we add more IP based product, we indeed plan to put that feature on our todo list!

@ ctrlaudio, the design of the board is as such (Digital link is only for digital input). Not much we can change unfortunately.

devteam - how tough is it to have USP in addition to ethernet? This would solve OSX issues

@ knuckle_head,
Unfortunately, not easy since the hardware board is already done and there is no USB driver solution. The whole firmware/software is also based on IP communication which makes it very hard (i.e. multiconnection) to do something similar with a USB port.

How difficult would it be, then, to swap out a 2x4 balanced kit in place of the on-board processor?

@ knuckle_head,

Icepower amplifier + DSP cards vs miniDSP platforms are VERY different. It just wouldn't be possible technically.

DevTeam

@devteam

Any updates on the stand-by feature and a new firmware for the pwr-ice 125?

Btw - could you please be so kind and update my account to be able to download software as my dealer doesnt really offer much software downloads related to your products.....

Thanks in advance
