quelqu'un connait il les différences matérielles entre les deux Minidsp OpenDRc -DI et DDRC-22D ???
visuellement ils sont identiques , et il semble qu'il utilise la meme puce Shark ADSP21369 !
Minidsp OpenDRc -DI :
Hardware
Analog Devices ADSP21369
32bit Floating point processing
Stereo digital inputs (AES-EBU/
SPDIF/Optical)
Stereo digital output (AES-EBU/
SPDIF/Optical)
ASRC for 20 to 216kHz input
Front panel volume control
IR control with learning feature
Item
Description
Digital Signal Processor
32bit Floating point Analog Devices SHARC ADSP21369 / 333MHz
Control
Driverless USB 2.0 control interface for Windows/Mac OS x environments A computer is only required for the initial configuration.
Digital Audio inputs
Digital audio source selectable from IR remote or Front panel:
- AES-EBU on Neutrik 3pin female XLR / Isolated with digital audio transformer
- SPDIF on RCA connector / Isolated with digital audio transformer
- Toslink on Optical connector
The input signal is processed by a high quality onboard Asynchronous Sample Rate Converter for compatibility with most common sample rate (20-216kHz)
Digital Audio outputs
Processed digital audio output from the DSP is available in all 3 formats:
- AES-EBU on Neutrik 3pin male XLR / Isolated with digital audio transformer - SPDIF on RCA connector / Isolated with digital audio transformer
- Toslink on Optical connector
Sample rate / Resolution
Resolution: 32bit
Sample rate: Depends on selected plug-in. Please consult plug-in datasheet for more information on the operating sample rate of the DSP
Template FIR filter capabilities
(Important note: FIR capabilities are controlled by the plug-in used and not the hardware itself).
Mono signal: FIR filter with up to 12228 taps @48kHz, 6144 @ 96kHz signal: FIR filter with up to 6144 taps/ch @48kHz
Please consult the plug-in specs for more info.
FIR filter storage
FIR taps coefficients & DSP configuration automatically loaded at bootup
USB port
USB port type B for real time control and firmware upgrade
Power supply
5VDC single supply / 600mA @ 5V - 2.1 round plug
Dimensions (H x W x D) mm
52 x 180 x 200mm

oups , il manque une information technique qui m'interesse beaucoup : Stereo signal: FIR filter with up to x taps/ch @96kHz , pour le MiniDsp DDRC 22D ??????
si c'est exactement le meme matériel que le MiniDsp DI , logiquement c'est 3072 (6144 /2) par canal en stéréo à 96khz ????
visuellement ils sont identiques , et il semble qu'il utilise la meme puce Shark ADSP21369 !
