D-rack ADDA?
« on: March 28, 2020, 05:58:06 AM »
Hello,

I got this Digico D-rack, its a stagebox 32in, 16out,
that talks to a console over Cat5e.
As far as I can read from the internet it's a proprietary protocol, since I don't have a digico SD9 console I have no use for it.
But of course I had to open it up.
It's modular,
2 switching power supplies,
4x 8-channel ADinput pcbs, PGA2500digi controlled preamps, TI PCM4204 chips
2x 8-ch DA, AKM4393VF, THAT1646line drivers
and a mainboard pcb: Xilinx spartan FPGA, ADSP21371 (mainboard seems to have water damage)

I'm wondering if I can do something with this, if it could be a basis for an ADDA converter?
Maybe over ADAT since for the moment I have an fireface400 interface with Adat ports.
Do we have projects here that could work?
I'm a noob when it comes to digital audio, and have no experience with programming except for some tinkering with an arduino.

You should have a MADI out in the Digico D-rack, no?

As far as I know Digico uses the MADI protocol.

Taking the MADI out and using a RME MADI card you can connect it and record to a computer I just don't know how you could control the Mic Preamps gain

Hi,

The protocol on the RJ45 is an implementation of Madi.

It can do 28x AD + 16x DA at 96K or 32x AD + 16x DA at 48K.

Control of gain/phantom is received via madi channel 57. These parameters can normally only be changed from a DiGiCo console.

Good luck!

If you email DiGiCo, they will send you a "secret" windows program that will let you control gain/pad/phantom as well as some other parameters from a computer via USB.

I haven't actually. I should try it. I'm sure the D-Rack would appreciate being fired up--has been sitting idle for a few months now.
