H8000FW: Routing ADAT in /out to dspA and dspB separately

[DiacK]

hello, and thank you for your effort in this forum.

i thought i understood, and it is working now, but i do not completely understand why, i had a different routing in my head which did not seem to work.

i want to use the H8000FW as two separate units, each getting stereo in and sending stereo out on there own dedicated channels using ADAT.

this is the routing i use now:

MAIN INPUTS

ADAT in 1 -> IN1 ADAT in 5 -> IN5
ADAT in 2 -> IN2 ADAT in 6 -> IN6
ADAT in 3 -> IN3 ADAT in 7 -> IN7
ADAT in 4 -> IN4 ADAT in 8 -> IN8

---

DSP A i/p routing

ADAT in 1 -> IN1

---

  -> IN5
ADAT in 2 -> IN2

---

  -> IN6
ADAT in 3 -> IN3

---

  -> IN7
ADAT in 4 -> IN4

---

   -> IN8

---

DSP B i/p routing

ADAT in 5 -> IN1

---

  -> IN5

ADAT in 6 -> IN2

---

  -> IN6

ADAT in 7 -> IN3

---

  -> IN7

ADAT in 8 -> IN4

---

   -> IN8

---

MAIN OUTPUTS (Analog)

dsp A out 1 (+) 

---

  -> ANA1
dsp A out 2 (+)  

---

-> ANA2

---

     (+) 

---

  -> ANA3

---

    (+)  

---

-> ANA4

---

MAIN OUTPUTS (Digital)

dsp B out 1 (+)

---

-> DIG1
dsp B out 2 (+)

---

-> DIG2

---

(+)

---

-> DIG3

---

(+)

---

  -> DIG4

---

ADAT Outputs

MAIN out 1 -> OUT1 MAIN out 5 -> OUT5
MAIN out 2 -> OUT2 MAIN out 6 -> OUT6
MAIN out 3 -> OUT3 MAIN out 7 -> OUT7
MAIN out 4 -> OUT4 MAIN out 8 -> OUT8

---

AES Outputs

---

-> OUT1 

---

  -> OUT5

---

-> OUT2 

---

  -> OUT6

---

-> OUT3  

---

> OUT7

---

-> OUT4 

---

-> OUT8

---

FIREWIRE1 Outputs

---

-> OUT1 

---

  -> OUT5

---

-> OUT2 

---

  -> OUT6

---

-> OUT3  

---

> OUT7

---

-> OUT4 

---

-> OUT8

---

FIREWIRE2 Outputs

---

-> OUT1 

---

  -> OUT5

---

-> OUT2 

---

  -> OUT6

---

-> OUT3  

---

> OUT7

---

-> OUT4 

---

-> OUT8

question 1

why do i have to connect the ADATin to the Main in AND the INs of the DSPs ? isn't it enought to connect the ADATin straight and only to the INs of the DSPs ?

question 2

how come that there is in the ADAT outputs menu not the possibility to  go from DSPout to the ADAT output ? wouldn't it be logical to have the DSPout as a possibility ?

question 3

did i connect it right?

thank you

Looks like it should work, although you may have to shuffle the ADAT channels.

To understand the routing you need to study the User Manual. In particular, use of the Factory Routings would have saved you a lot of time. Look at "ADAT 8 Track A,B" on  page 30 of the latest manual – this is essentially what you are trying to do.

To answer your specific questions:

question 1

why do i have to connect the ADATin to the Main in AND the INs of
the DSPs ? isn't it enought to connect the ADATin straight and only to
the INs of the DSPs ?

Basically the unit has a main input block "MAIN INPUTS" to which you have connected the ADAT inputs. The you have to connect the DSP inputs to the main input block. This is similar to the use of what used to be called "binding posts."

question 2

how come that there is in the ADAT outputs menu not the possibility
to  go from DSPout to the ADAT output ? wouldn't it be logical to have
the DSPout as a possibility ?

Again you have a main output block "MAIN OUTPUTS" which is fed by the DSPouts. You then connect this to the other outputs.

question 3

did i connect it right?

I think so – does it work ?
