This method combines a unique conversion process for IMAX theatrical audio mixes utilizing an enhanced DTS codec technology. The IMAX theatrical audio format with point source surround speakers closely matches the speaker configuration most consumers have in their homes today. Coupled with DTS audio technology, IMAX Enhanced audio products will ensure the best and most accurate audio reproduction over 5.1 or more speaker channels.

Audyssey LFC™ (Low Frequency Containment)

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™

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® XT32 to both subwoofers together for improved deep bass response and detail.
