Pick & choose your I/O cards to fit your needs
Similar to how one would buy a PC motherboard and select the PCI cards that best fit his system, miniDSP can be upgraded and configured with different I/O cards. All configurations are done by a software file residing in the plug-in folder. Some of you may want digital inputs while others will need balanced inputs. Put it simply, the perfect audio product is far from a real product for most audio DIYers... No matter how well we try fulfilling your expectations, there will always be someone asking for an odd feature that others may not want to pay for. Our answer to this problem is to let you pick & choose the I/O configuration and plug-in you need for your application.

While these cards are still in prototyping stages and yet to be released in the next few weeks, here is a quick preview of what is to come:

Digital I/O card: The perfect fit to input your SPDIF/Optical signal to your board. Fitted with a Sample Rate Converter (SRC) to process digital audio sources, no matter what type of sampling rate.
Multi-channel low&high power Digital amplifier cards: Targeting a complete all-in-one processed amplifier solution for active speakers, this serie of modules will complement nicely the miniDSP product range.
High Fidelity Input & Output card: For those of you believing their system needs greater dynamic range, this card will be a perfect fit for balanced input, balanced output.
and much more to come...
Stay tuned for an exciting year!

Co je tam za procesor a ADC/DAC? Ultimátní řešení je http://www.lyrtech.com/index.php?act=view&pv=PADK .$1495 bez SW . Ale pro práci je třeba již nějaké know-how (číslicové zpracování signálů, programování DSP)
