Topic: ADI2 Pro - DSD recording meaning what exactly...?
Hi everyone,
glad I found this forum - have a sort of "long" question. Since there is no extra sub-forum for ADDA converters - I hope I'm right in this section.
I am strongly interested in the ADI2 Pro - looks like a dream came true.
Should serve me as the Pre-Pre-Interface for recording + decent Headphone Amp + USB connector.
Everything in one box - great job guys.
The functionality I am -really- looking for (in a perfect world) is this:
1) 2 ch Analog Source via XLR > ADI Pro 2 analog In || Check
2) Separate channel Input level Control for L / R || ? Not sure... but no showstopper.
3) Adjustable highpass filter for analog Input || Check ?
4) Equalizer stage (channel separated...) > do what I like to the signal or do nothing at all || Check I think
5) Digital output vs. analog... now it gets serious, and here is my main question:
I do own a Tascam DA3000 solid state recorder - would love to use the digital DSD -Inputs- of that machine, after the ADI2 Pro.
Can those two mate -digitally-?
Input Connection on the Tascam is:
SDIF-3 (unsymmetrical)
- Connector: 2 x BNC (L, R)
- Format: SONY SDIF-3/DSD-raw
- Clockfrequency: 44,1 kHz (at 2,8 MHz or 5,6 MHz)
Otherwise the Tascam can record every analog input to DSD 2.8 or 5.6 - no problem.
Generally I found very little info on the DSD "recording" possibilities of the ADI2 Pro in general.
The digital output modes for the ADI2 pro as listed online (in German):
-------------------------
AES/EBU
• 1 x XLR, trafosymmetriert, galvanisch getrennt, nach AES3-1992
• Format Professional nach AES3-1992 Amendment 4
• Single Wire Mode, Samplefrequenz 28 kHz bis 200 kHz
SPDIF coaxial
• 1 x Cinch, nach IEC 60958
• Format Consumer (SPDIF) nach IEC 60958
• Single Wire Mode, Samplefrequenz 28 kHz bis 200 kHz
SPDIF optical
• 1 x optical, according to IEC 60958
• Format Consumer (SPDIF) nach IEC 60958
• Samplefrequenz 28 kHz bis 200 kHz
-------------------------
This looks as if the ADI2 Pro can give DSD recording output "only" as an analog signal, meaning "in the last step" there is a DA-conversion to the output signal.
It follows, that my DA 3000 must do another AD-conversion for the analog Input - which it is capable of of course. My "dream" is to avoid that DA-AD step for the recording device.
Also confused about the "BO968 breakout connector", it gives AES/EBU Input/Output and SPDIF coaxial Input/Output to the DIGI96/8 PRO which is no longer in Production (?) - maximum digital Input configuration for this card is 96/24.
My final conclusion:
The "best possible digital connection" between the ADI2 Pro and the Tascam is a 192 KHz / 24 Bit via the AES output or the SPDIF coax provided with the BO968 (the DA300 could accept 192/32 Bit as max. non DSD rate...)
"DSD recording capabilty" of the ADI2 Pro means that it outputs an "analog DSD-Quality-Signal", not a digital one.
Right or wrong? Or totally confused ...
THX for
Best regards
