Topic: HDSP 9632 AES to Fireface

@ RME Support
I need a few clarifications please about the AES output pins, I have this scenario:

If one uses that AES output of the HDSP9632 into a Fireface, via a custom cable, no xlrs etc, (following the pinouts in the manual),

without toggling professional in the HDSP settings,:

-doubled output voltage will not be output without this setting correct?
-without this setting, the output will be plain spdif, a mirror of the regular spdif output, with regular spdif voltage ?
-will toggling Professional & using the SPDIF output, output the same doubled output voltage AES as via the AES pins ?
-Is there any Totalmix version that displays this info (other than the professional bit status) ?

Correct.

The 9632 has only one output transmitter and encoder. So yes.

The SPDIF output will double it's voltage too but typically not exceed 1.x volts pp.

TotalMix? You mean DIGICheck?

Re: HDSP 9632 AES to Fireface

Thank you Matthias, Yes I did mean digicheck.

-Is there any Digicheck version that displays this info (other than the professional bit status) ?

-Matthias please help me Clear these issues:

1. So basically, If I need AES out, I can use either THE SPDIF pins or AES pins,
    and get the EXACT SAME VOLTAGE & BIT OUTPUT from BOTH, ?


2. So if it is the same transmitter to both outputs :
    If I Use BOTH OUTPUTS (with toggling Professional) & wire each to a different AES device, to make it a splitter,
   Am I risking overloading the card ?
   
3.Is there ANY difference whatsoever between the spdif pins & aes pins ?

A software can not measure a physical voltage.

No, the SPDIF output has lower voltage.

No, you can do so and usually it will work as most AES inputs start working at below 0.5V pp.

The impedance (minor) and the voltage (major).

-Thanks, So :

Without Professional ticked, Both AES & SPDIF Pins will show the EXACT same voltage if measured or show a difference?

With Profssional ticked, The spdif output will double , but the AES output will measure higher ?

Re: HDSP 9632 AES to Fireface

Output / Consumer / Professional
SPDIF : 0.8V / 1.5V pp
AES : 2.0V / 3.5V pp
