VM9021TS
AUDIO Menu
The VM9021TS has a built-in Pink Noise generator to help
set the relative speaker levels for multi-channel audio
playback.
NOTE: When Down Sampling is ON, the audio output
signal will be converted to 48kHz. When Down Sampling
is OFF, the original sampling frequency is preserved.
SPK CONFIG Menu
To change speaker settings for 2-channel mode, use the >>
or
<< buttons (14, 22) on the remote control or the /\ or V
buttons (6, 7) on the joystick to select “DownMix”. To change
speaker settings for 6-channel mode, select “Full 6CH”.
After
selecting 2 or 6-channel mode, use the >>| button (19) on
remote control or the > button on the joystick (9) to move to
the speaker settings on the right.
Speaker Selection
Selecting LARGE for the multi-channel speaker option will
give a full range output. Selecting SMALL for the multi-
channel speaker option will activate a high pass filter whose
crossover is dependent upon the sub-woofer low pass filter
frequency. For example, if the subwoofer low pass filter is set
to 80Hz, then the high pass SMALL speaker crossover will be
set to 90Hz.
Low pass High pass
80Hz 90Hz
120Hz 135Hz
160Hz 180Hz
Refer to Table 16 when selecting speaker options for each
mode.
Surround Sound
Dolby Digital
Dolby Digital is the reigning standard for surround sound
technology in general and 5.1-channel surround sound in
particular.
Dolby Digital is a highly sophisticated and versatile audio
encoding/decoding technology. Dolby Digital technology can
transmit mono, stereo (two-channel), or up to 5.1-channel
surround sound.
Pro-Logic II
Pro-Logic II is a dramatically improved matrix surround
system based on the original Dolby Pro Logic system. Pro-
Logic II offers two full-range stereo surround channels, more
sophisticated steering logic, high channel separation and an
exceptionally stable sound field. Dolby Pro-Logic II uses
simple servo circuits used to derive the five audio channels.
Unlike other "Surround Effects" found in other consumer
equipment, Dolby Pro-Logic II does not introduce unwanted
delays, echoes, reverberations or tonal colorations.
