Audio Set-Up; Digital Audio Output - Arcam DV135 Handbook

Audio set-up

This section allows you to configure 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 configures the digital audio output – coaxial, optical and
HDMI.
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.
Note that this setting is relevant only to the output from DVD-video discs.
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.
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
significant video delay. The 'Delay' menu items allow correction of this effect by delaying the audio
soundtrack up to 150 milli seconds. The amount of correction required in a given system is best
determined by experimentation.

S/PDIF When the 'Stereo PCM' digital output is selected, all audio material played is
stereo PCM 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 The Bitstream setting supports the following audio standards:
bitstream
<
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 cannot decode audio
or if you are connecting to a DVI device (since a DVI link cannot carry
audio) – choose one of the other settings instead.
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.

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 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.

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
by setting these items to 0ms (no delay).
