DV135
E-14
Audio set-up
This section allows you to congure the analogue, digital and HDMI
audio outputs. In particular, the digital output type needs to be set
correctly if you are using an external audio decoder, receiver or D-A
converter.

Digital audio output

This setting congures the digital audio output – coaxial, optical and
HDMI.
S/PDIF
stereo PCM
When the ‘Stereo PCM’ digital output is selected, all audio material played is
down-mixed to stereo and output as stereo PCM. Use this setting if you have an
external D-A converter that supports only 2-channel PCM.
S/PDIF
bitstream
The Bitstream setting supports the following audio standards:
< 2 channel PCM (on CDs or DVDs)
< Dolby Digital
< MPEG multi channel
< DTS multi channel
Use this setting if you have a receiver/decoder that supports Dolby Digital.
HDMI (Auto) Select this item if you are using an HDMI connection between your DV135 and
your receiver or display device.
The audio type will be changed automatically to work with the device attached to
your player.
Do not select this item if your HDMI display device or surround-sound
receiver cannot decode audio over HDMI, or if you are connecting to a
DVI device (since a DVI link cannot carry audio) – choose one of the
other settings instead.

DVD sample rate

This needs to be set correctly if you are using an external audio decoder, receiver or D-A converter
connected to the S/PDIF digital audio output.
Max 96KHz Choose this option if your external audio decoder is able to process digital audio
with a sample rate of up to 96kHz, or if you are not using the digital audio
outputs. This is the maximum sample rate present on DVD-video discs.
Max 48KHz Choose this option if your external audio decoder is unable to process digital
audio with a sample rate of up to 96kHz. This is the normal setting for this
menu item.
Note that this setting is relevant only to the output from DVD-video discs.

Audio compression

This option allows compression of the audio stream to be turned on or off, where ‘On’ is intended for
‘late night’ listening when large volume changes are not desirable.
Turning compression on decreases the volume of the louder passages, i.e., the total dynamic range of
the audio is reduced. Normally, however, this item is set to ‘Off’, to disable compression.
This menu option affects both the analogue and the HDMI outputs (although note that the HDMI output
is affected only when multi-channel uncompressed audio is requested by the receiver, not otherwise).
The co-axial and optical digital audio outputs are never affected by this menu setting.
Compression is available only on Dolby Digital recordings.

VCD mode

Some VCD discs are produced with a dual-mono soundtrack. This means that the left audio channel
carries one language, the right another. In this case it can be useful to listen to just one of the channels.
Stereo The default setting. Choose this option to play the VCD with both channels
audible.
Left channel only Choose this option to play the VCD with only the left channel audible. The audio
from the left channel will be routed to both the left and right speakers.
Right channel
only
Choose this option to play the VCD with only the right channel audible. The audio
from the right channel will be routed to both the left and right speakers.
This setting applies only to VCD discs.

Video post-processing (lip-sync.)

Delay for NTSC (ms)/Delay for PAL (ms)

Modern displays and video scalers often employ digital video processing that can introduce a
signicant 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 DV135 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 DV135 is in use, the player corrects automatically for its
own processing delays and it is unlikely that additional delay will be necessary. Therefore, start
