Topic: Low output level on MADI FX card

Hi there

I changed my system from a RME Fireface 400 to a RME MADI FX card. The analog stereo OUT of the MADI FX card goes into my monitor controller. I have the impression that the output level of the MADI FX card's stereo output is much lower than my previous Fireface 400. I have to turn up the volume knob of my monitor controller around 25% more to reach the same loudness. Is there somewhere a setting where I can adjust the output level of MADI FX card's analog output?

regards
Nico

Re: Low output level on MADI FX card

This information you can find in the manual and by reading the product specification.

Then you will see that the FF400's balanced line outputs were switchable between different reference levels up to +19 dBu @0 dBFS.

The analog monitoring port on the HDSPe FX card is mainly being used as phones port (TRS, unbalanced), but can also be used as unbalanced line output. It has no switchable reference levels and has a lower max output level of +13 dBu @0 dBFS, which is +6 dB lower compared to ref level "High Gain" on FF400 which delivers up to +19 dBu @0dBFS.

"Analog Monitoring Output
The HDSPe MADI FX provides an analog stereo output in reference quality with RME's proven low-latency converter technology. The output is ideally suited for high- and low-impedance headphones.
Thanks to the powerful monitoring features of TotalMix, any input channel, recorded tracks, or complex sub-mixes can be selected for listening. An advanced Cue function allows each of the 98 possible stereo sub-mixes to be monitored with just a single mouse click.

Re: Low output level on MADI FX card

Thanks a lot, ramses.
I did check the manual but somehow overread this section. I searched for "analog output", not monitor output.
So, if this single stereo out is more for headphones, I will use my A/D's analog Out to connect to my SPL monitor controller.
Thanks, again.
