DIGI 003R BLA SIGNATURE + MARIAN ADCON = summing problem !HELP! DAW Software
Old 5th September 2011
Here for the gear

Hi fellows!

I'm having a trouble here and I would love if you could help me understand what's going on.

I have a Marian Adcon A/D D/A converter connected in a DIGI 003R Black lion Audio Signature Series Mod ADAT Optical Output. I'm using the ADCON to output + 8 analog channels from the DIGI to my 16 channel passive summing mixer (total: 8+6=14 channels summing).

The problem is, somehow, the audio signals that come from the ADCON have less 17 dB than the ones coming from the DIGI Analog Outputs, but they're both going through the same summing. This way I have all my mixing work messed up by this dB drop, which I have to compensate in the send of the pro tools channels before the output, but the 17 dB compensation looks terrible because I need to send the "good"(digi) channels with a lower gain than I should (to prevent the material to clip digitally in the pro tools mixer), once the fades have only +12 dB option and I need some headroom for some changes I may have in the busses.

I've tried changes all cables, ins, outs and I figured out the difference is between ADCON and DIGI003 analog outs, but I don't know why, nor if it's a defective or a normal issue due to impedance difference or something else.

I need to know the reason. I need to know if changing the ADCON for another brand converter would fix this or it's BLA MOD that have a higher signal and there's nothing I can do about it.

Could somebody please, help me?!
