When I turn up the volume (no music not course but to see how quiet it could be) to about +10dB, I can hear some low frequency heart-beat-like noise coming out from my speakers continuously. It will go louder and louder if further turning up the volume.
Did you experience the same OR is it normal?
I use D200.
I experienced this with 7.1 on every input as I got up to +15 dB or so, (with nothing playing, as this would be deafeningly loud)
No issue performing the V8.0 update, but a fresh, new configuration file is needed; which was not clearly mentioned in the update notes. Old saved configuration files were not retrievable from the updated website when I tried.
I've noticed the same problem with my D250 after updating to V8.0: low frequency rumble & intermittent beating noise at high volume setting close to 0dB & above with no input signal; never had this issue before. It used to be dead silent with no input signals even at 0dB & max volume setting.
Also discovered a new problem with SAM 2.0. I use Velodyne DD10+ sub in parallel with my speakers (dual-mode using speaker level inputs to the sub for stereo & LFE from AVR for home theater system). I ran the Velodyne low frequency tone sweep calibration CD after the update, and noticed loud glitches (clipping) from the D250 at the beginning of the tone sweep (from low, subsonic to high). The glitches are gone with SAM disabled. I've never had this problem before V8.0. It appears SAM or SAM woofer protection is causing the glitches (hard amplifier clipping).
