DV137
E-19
Video post-processing (lip-sync.)
Delay (NTSC/PAL)
Modern displays and video scalers often employ digital video processing that can introduce a
signicant video delay. The ‘Delay’ menu items allow correction of this effect by delaying the audio
soundtrack up to 150 milliseconds. The amount of correction required in a given system is best
determined by experimentation.
<
If the interlaced video outputs of the DV137 are in use and the display is converting the signal to
progressive scan then we recommend a delay of 50–80ms, depending upon the display.
<
If the progressive video output of the DV137 is in use, the player corrects automatically for its
own processing delays and it is unlikely that additional delay will be necessary. Therefore, start
by setting these items to 0ms (no delay).
Trim set-up
The relative sensitivity (volume) of different speakers can lead to some speakers
sounding disproportionately loud or quiet, relative to others in the system. The trims
setting of your DV137 can help to address this inbalance.
This page is relevant only if you are using the analogue audio outputs of the DV137 to
connect to your amplier/receiver. If this is not the case, set all the trims to be 0 dB.
Test Noise
Setting this item to ‘On’ causes pink noise to be generated from the speaker indicated by
the on-screen highlight. The noise is at the volume indicated by the slider for the speaker.
Setting this to ‘On’ may be useful in ensuring that the relative volume for each speaker is
the same.
Note that this setting is set automatically to ‘Off’ on exit from this menu page.
Trims
Trims for all the speakers can be set using the associated sliders. These settings are useful if the
speakers have different sensitivities (and so have different volumes for the same input levels). The trims
can be set in 1dB steps.
Subwoofer/Sub with stereo trims
Both the ‘Subwoofer’ and the ‘Sub with stereo’ trims control the subwoofer trim setting. ‘Subwoofer’ is
the trim used when multi-channel material is being played; ‘Sub with stereo’ is the subwoofer trim used
with 2-channel material.
Completing the set-up
Complete the set-up procedure by pressing SETUP on the remote control. This saves all the data and
closes the set-up menu. You can press SETUP at any time while in a menu to quit from it.
To return to the set-up menu at any time, ensure that there is no disc playing and press the SETUP
button.
