4A. LFE LEVEL
Use this feature to adjust the output level of the LFE (low frequency effect) channel when playing back DTS encoded software. This
setting is effective only when this unit decodes DTS signals. The LFE signal carries the low frequency special effect sound which is only
added to certain scenes.
You can adjust the levels from –10 dB to +10 dB.
Adjust the LFE level according to the capacity of your subwoofer or headphones.
5. SP DELAY TIME
Use this feature to adjust the delay of the Center and the Rear Center channel sounds. This feature works when this unit decodes DTS or
Dolby Digital signals. Ideally, the Center speaker and the Rear Center speaker should be the same distance from the main listening position
as the left and right Main speakers. However, in most home situations, the Center speaker or the Rear Center speaker is placed in line with
the Main speakers or the Rear speakers. By delaying the sound from the Center speaker and the Rear Center speaker, the apparent distance
from the Center speaker and the Rear Center speaker to the main listening position can be adjusted to make it seem the same as the distance
between the left and right Main speaker, and the left and right Rear speakers to the listening position. Adjusting the delay time for the Center
speaker is especially important for giving depth to the dialogue.
You can adjust the delay time from 0 ms to 5 ms for the Center speaker and from 0 ms to 30 ms for the Rear Center
speaker.
Increasing the delay 1 ms simulates moving the speakers about 30 cm (one foot) farther away from the listening position.
6. AUDIO DELAY
Use this feature to adjust the delay time of all channel sounds, when this unit decodes DTS or Dolby Digital signals. Adjusting AUDIO
DELAY is especially important for matching the sounds to screen pictures. Initial settings is “0ms”.
You can adjust the delay time from 0ms to 99ms.
