■ 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.
