Audyssey LFC™ (Low Frequency Containment) (v p. 185)
0
Audyssey LFC™ solves the problem of low frequency sounds
disturbing people in neighboring rooms or apartments. Audyssey
LFC™ dynamically monitors the audio content and removes the low
frequencies that pass through walls, floors and ceilings. It then applies
psychoacoustic processing to restore the perception of low bass for
listeners in the room. The result is great sound that no longer disturbs
the neighbors.
Discrete subwoofers and Audyssey Sub EQ HT™ (v p. 210)
0
The unit has two subwoofer output capability and can adjust the level
and delay for each subwoofer individually.
Audyssey Sub EQ HT™ makes the integration seamless by first
compensating for any level and delay differences between the two
subwoofers and then applying Audyssey MultEQ
subwoofers together for improved deep bass response and detail.
