TOPIC:

According to this diagram www.minidsp.com/applications/subwoofer-tuning/ddrc24-multisub the Computer doesnt actually connect to the AVR

I'm able to get sound going to the sounds throught the DDRC24 but levels are way to low - even at Master Output set to -12.5db, and Mic Gain (Umik1) at 100% the levels i get is something like -30db and i get a too low noise to signal ratio error

The problem with going thru the AVR is that its in way in the back and i dont a long enough HDMI cable lol was hoping i didnt need to use the AVR directly to calibrate the subs

Same with this image www.minidsp.com/applications/subwoofer-t...tuning-multiple-subs

Go to the AVR's channel levels and increase the gain of the sub output.

My guess is that you've got a volume setting on your laptop/PC that is low and affecting the output level. The AVR volume should make no difference if you have things connected as in your first photo.

Answer: Default volume on ddrc was something like -12db :/
