DSP OPTION

LIP SYNC DELAY

DSP Options has the feature "Lip Sync Delay" whose function is to match

any delay that may occur in the picture relative to the audio.

By varying "Lip Sync Delay" from 0ms to 120ms, one can delay the audio

output in order to synchronize it with the video image.

The T 748 has two Tone Control levels – Treble and Bass. Bass and Treble

controls only affect the low bass and high treble leaving the critical

midrange frequencies free of coloration.

These controls allow one to tweak on-the-fly, the frequency response of the

source during playback. The control setting could be adjusted by navigating

through the Tone Controls' OSD menu via a combination of [ ENTER ] and

[ A/S/D/F ]keys.

Maximum and minimum values for all three Tone Control levels are ±10 dB.

"Tone Defeat" gives one the choice of varying or completely bypassing the

tone control section of the T 748. If "Off" is selected, the Tone Control circuits

are active.

Select "On" to bypass the Tone Controls effectively defeating the effect of

the tone control circuits.
