| Post subject: | Marian Seraph MKII sound card driver setting |
Marian has recently updated their Seraph sound cards. By default, they now have a slightly flatter frequency response, but that comes at a cost in phase response. When testing the new cards we found that we got up to 10% overshoots in our MPX signal. We have contacted Marian about this and they have created a new driver that has a setting to get the old/normal behavior back. So, if you have an MKII card, please perform the following steps:
We will add a setting in Stereo Tool soon to make the response completely flat (with these settings you loose about 0.3 dB at 57 kHz, similar to what the MKI cards had - since we know that the filter is phase linear we can easily compensate for it, so look out for a "Seraph MKII" checkbox in the near future). |

Hans you remember the MPX Passthrough thing? Do you think you can make it pass a complete 192khz signal into the FM Output? The calibration from the FM Output section is outstanding with my realtek soundcard.

Is this also the case with the (new) Clara soundcards? I've recently bought a Marian Clara B soundcard and am planning to install it soon.We have contacted Marian about this and they have created a new driver that has a setting to get the old/normal behavior back. So, if you have an MKII card, please perform the following steps:
Do I also need to set DAC to "Linear Phase, Slow Roll-Off"? And is the setting you mentioned already in ST l? I haven't really checked yet. |

Marian has updated their driver default settings after we told them about this, so this isn't necessary anymore! At least not if you buy a new card and (only) use the latest driver version. ST setting isn't there yet, and we're planning to check the Clara card soon. |
