Misschien ook een plan voor ZBA? We staan altijd open voor suggesties...
bij deze dus!
even wat citaten uit t DIYAudio topic alvast:
op DIYAudio, sek schreef:In an integrated module (as in fully equipped) I don't look for much more than the anticipated [url="http://www.hypex.nl/docs/PSC2.400.pdf"]PSC2.400[/url], as I'm advocating balanced signal handling as well as professional connectivity. I'll have to criticize the panel size, though, as the mounting dimensions are way too large in order to fit into a compact stage speaker box or monitor - at least according to my taste.
The lineup would indeed have to be completed by an accompanying subwoofer module, though. I can see this coming as soon as Hypex managed to finish their higher power SMPS products.
A module with a three way configuration for full range speakers would be nice, too. But Hypex already knows this from many DIYers...
As far as my requirements go, it's the DSP module development that bugs me here. Hypex already has got a well done implementation of a dedicated audio DSP (with reduced computing power and fixed audio firmware) integrated into ready made products like the [url="http://www.hypex.nl/docs/AS2.100/Manual%20AS2.100%20V1.2.pdf"]AS2.100[/url], but has no plans to release this one as a separate product.
I can see an opportunity missed here. I would buy it. Many speakers don't require full-fledged six-channel universal processing. OTOH, many speakers require their own built-in module, though.
A six-channel board couldn't go into an active speaker (or subwoofer), as this wouldn't make a lot of sense when it comes to signal routing and cabling. Thus, it would be a product for a preamp or an integrated multi-channel amplifier.
So, basically, I foresee a gap in the lineup. Speaking of me, I won't buy the AS2.100 for hifi speakers, as I'm never going to use a two-way setup without a woofer - either as a third crossover way in the box or in a separate subwoofer enclosure. OTOH, just buying many AS2.100 can't be the solution for DIY hifi, as this would be way more complicated (and less DIY) than just buying ready-made amplifiers and buying the DSP unit(s) from another manufacturer.
I'd wish for the small two-channel DSP module (and the accompanying digital I/O module) to be released separately.
op DIYAudio, qusp schreef:I for one would also be interested in a small 3 way board to be mounted in small monitors, that will be my next project whether it is hypex or another (perhaps a bit more DIY) solution. the hypex stuff does indeed sound and work great (not an owner, but friend of one) but I like to have more to do with something than just wire it up, but thats just me.
op DIYAudio, Henkjan schreef:my wish-list for the perfect stand alone DSP module:
- full preamp replacement, so volume and source selection, plenty analog and digital inputs, the latter in all available formats (CD, SACD, DVD-A) and connections (coax, optical, USB, hdmi, etc) analog balanced and unbalanced, all high quality connectors enabling the use of high quality cables
- a few presets (like audiophile, movie, party) for the DSP part selectable with the remote, with the chosen one remembered for each input
- in the DSP a delay large enough to also use it with a corner woofer sat/sub system, so some 1 or 2m difference in location between channels
- remote trigger for powering on the amps, an (optional) relais switched power strip would be nice for this, or something in the other Hypex products to communicate with the DSP
- expandable to a 7.1 (7.2) system for HT, accepting digital in from DVD or BR and able to decode the usual suspects as Dolby D, DTS, etc
- the software has either a built in measurement module, and/or a good interface with e.g. Arta is possible, and/or good importing of measurement data (not only impulse, but also FRD). possibility to use averages of multiple measurements.
op DIYAudio, sergiof schreef:adding to the wishlist, it should have a digital out. that would give us at least two big advantages:
- the chance of using a digital amp
- the chance of using the ADC (backing up our LP/analog tape collection).
op DIYAudio, Henkjan schreef:on the 7.1: how about 5.1 then? what I mean is that is is able to decode movie sound from a DVD...
op DIYAudio, Colin schreef:As I've moved from my old hi-fi, I realise that all my input requirements are now digital. My wish-list is therefore very simple - a straightforward, two-channel preamp which accepts 3 or 4 digital inputs. has a remote control volume and a line output. If it has more outputs, that's fine. If extra outputs can be routed off to provide two-channel outputs to a poweramp in other rooms, even better.
op DIYAudio, sek schreef:As an example for how to offer a better product than the competition (and your former lineup), here's an important lack in Hypex' approach so far: multi platform compatibility! You shouldn't make the mistake to force your customers into using Windows 2000 style software any longer. Serving the Mac OS platform is one of today's requirements in a multimedia home, studio or broadcast environment. Serving the linux platform is one of today's requirements for integrated/embedded devices. Thus more OEM products aimed at the (semi-) professional or high end market would be possible.
Recommendation: make it platform independent. Use only (open) standards, a well thought out software architecture and develop separate UIs for different operating systems. With today's software development techniques this is easier than you might guess. Just think of the OEM (end user) market. People will have to use an interface (either hardware or software) in their everyday life.
Digital output should at least not be prevented. Some DIYers (like me) might want to daisy chain (and interconnect) digital stages, AES/EBU might be necessary for this.
en dan de antwoorden van Matthijs:
op DIYAudio, Matthijs_Hypex schreef:Thanks, that's one thing we are searching for. The perfect solution to use the "same" board also as 2 two and 4 channel. And besides this we will also have to look for a good solution to make the board compatible/configurable with all of our other products, UcDxxxST/UcDxxxHG/ and OEM series together with either a linear or a switched mode power supply.
We do want to take some time for this so we won't have to disappoint some first buyers for missing features on they product.
op DIYAudio, Matthijs_Hypex schreef:Preamp replacement: We want to set up the board in blocks, on block is the DSP (2/4/6 channels) to which other universal boards can be connected to. For example a input routing board, for example one board with 1x Analogue and 1x AES inputs. And maybe an other board with 4x Analogue (balanced and unbalanced) in and 4xAES in etc. With this setup the user can even make his own dedicated input boards.
This should also be done for the other parts, compatibility with our SMPS-es, and control boards, with display or not, and different sizes.
Because we use an other DSP we are also able to increase the delay so that won't be a problem.

it should have a digital out > I'm sorry but I don't think we will go for this option, at least not for now
op DIYAudio, Matthijs_Hypex schreef:Oke there are two kinds of digital outputs:
1 digital throughloop, meaning that the digital signal that goes in also comes out, without any processing, delay or channel selection.
This is the digital out that IS available on the new 6-channel DSP
2 You could also include a digital out after the DSP. But this means you also need the converters for this (one digital standard to AES/EBU standard) and you need processing for this.
This is the digital output that will NOT be available on out hardware
