Room electronic acoustic correction Samson D-1500 RTA and Samson D-2500 EQ AUTO-EQ system

there was not a single video documenting how marvelous and easy is to callibrate audio systems with this hidden gems by Samson Tech using the auto EQ mode. I am using the Samson D1500 Real Time Analizer and the D2500 Digital Equalizer for calibrating a pair of M-Audio LX4 and Presonus Eris4.5 the prm1 measuring mic goes straight into the RTA, and the AT2020 is intended for your listening pleasure. i toggle between the rta and the graphic eq mode on the d1500. check how the frequencies are flattened overtime. there is a deep rumble at 65 Hz, but this is because lower frequencies are treated with another processor. that is why it does not do anything below 85 Hz. we have a filter on it.
