Just setup my Onkyo TX-NR696 receiver (7.1 w/1 sub)  & I noticed all 3 presets for the equalizer are all flat  across the board. DO folks normally just leave it alone or adjust  manually? If you adjust, what are your settings?
Also,  when playing music from my thumb drive via the rear USB port, I noticed  that I can only randomize the play of songs in 1 folder at a time. Is  there a way to set it to play all songs on the entire drive in random  order?
