HDMI Audio
Two options are available: PCM Stereo and Follow SPDIF.
When HDMI Audio is set to ‘PCM Stereo’, the HDMI output will always be 16/44.1 for
CDs and 24/48 stereo or stereo downmix for DVD.
When the DV30 is connected directly to a TV set which can receive stereo audio over
HDMI, PCM Stereo is the best setting to use. Your TV set will then always receive a
two-channel downmix from CDs or DVDs.
When HDMI Audio is set to ‘Follow SPDIF’, the HDMI output will follow exactly the SPDIF
output as per the previous section and table. When the DV30 is connected to an AV
receiver by HDMI, there are two possibilities depending on whether the receiver
accepts HDMI audio directly or switches HDMI video and uses SPDIF for digital audio
reception:
1. For AV receivers that can receive HDMI audio, set the HDMI Output to ‘Follow SPDIF’.
Now set the SPDIF Output to ‘Raw/Bitstream’. The AV receiver can now decode the
bitstream over HDMI into the formats it supports. The TV itself will then not receive
any audio (unless the receiver has the capability of making a stereo downmix and
outputting it over HDMI).
2. For AV receivers that switch HDMI and use SPDIF for audio reception, set the HDMI
output to ‘PCM Stereo’ and set SPDIF Output to ‘Raw/Bitstream’. The AV receiver
now receives and decodes surround-sound via the SPDIF connection. The TV will
always also receive a two-channel downmix directly from the DVD player over HDMI
which can be used if desired.

Dynamic
Dolby Digital encoded discs allow for the dynamic range (the difference between loud
and quiet passages) to be compressed (i.e. for late night listening). The options are:
Full, 7/8, 3/4, 5/8, 1/2, 3/8, 1/4, 1/8, Off
When ‘Full’ is selected, the peak-to-peak value of the audio signal is compressed by
the maximum amount. When ‘Off’ is selected, no compression is applied.
