SAM effects

[f1eng]

Indeed - this would limit options integrating a sub. I actually discovered this for a different reason. I had be loaned a Tom Evans Groove phono stage, which I tried with the Devialet. I noted that I was suffering some minor "environmental feedback", i.e. the bass cones were moving excessively at very, very low frequency. I noticed that this effect could be lessened by walking very gently to and from the turntable, which shows you how sensitive turntables are, and I have a concrete floor. I decided to set a high pass filter in the configurator, say at 10hz, to eliminate this issue. However, all the settings were "greyed out" in the GUI. Removing the SAM from the configurator, and the settings become available again. As a point of note, the cone movement issue is eliminated by the Devialet's own phono stage, which apparently includes a subsonic filter. Curiously, another way to eliminate the cone movement issue when using the Tom Evans phono stage was to crank the volume up! Why, because SAM kicks in and says "no" to what would be too larger cone movement.

Have a look at the configurator of the phono input. Check that you are using the 1976 RIAA curve, not the 1953. The 1976 curve includes a subsonic rolloff to prevent the inevitable subsonic grodge from a turntable getting to the speakers
That will open up the subwoofer and SAM possibilities.
