Auto: Select for automatic detection of the input signal format.
The input signal format (Dolby Digital, DTS, MPEG, PCM or
Analog) used by the selected input source is detected
automatically to execute the required decoding process. If no
digital signal is input, the input signals to the analog input
jacks will be played.
AC-3RF: Select if a LD player with an AC-3RF terminal is
connected to the AC-3RF input on the TX-DS989. AC-3RF
can only be selected if VIDEO 4 is selected as the input source.
Digital: Select for automatic detection of a digital input signal
format. The input digital signal format (Dolby Digital, DTS,
MPEG, or PCM) used by the selected digital input source is
detected automatically to execute the necessary decoding
process.
DTS: Select for DTS signal processing. The decoding process is
executed only when DTS signals are input.
PCM: Select for PCM signal processing. The decoding process is
executed only when PCM signals are input.
Analog: Regardless of whether the component is also digitally
connected, the audio signals input from the component
through the analog input jacks are played.
Notes:
• If “Auto” or “Digital” is selected and a compact disc or LD is
fast-forwarded during playback, decoded PCM signals may
produce a skipping sound. In such cases, change the setting to
“PCM.”
• If a compact disc or LD encoded in the DTS format is played
back with “PCM” selected, only noise will be produced.
Always select “Auto,” “Digital,” or “DTS” when playing back
DTS-encoded sources.
Notes on DTS:
• If you play a CD or LD that supports DTS when the “PCM”
setting is selected on the TX-DS989, the DTS encoded signal
will not be decoded and noise will be output. This noise could
damage the amplifier and speakers. Therefore, be sure to
selected “Auto,” “Digital,” or “DTS” and use the digital input
jacks (OPTICAL or COAXIAL) to connect the DTS source.
• If you play a CD or LD that supports DTS when the “Auto” or
“Digital” setting is selected, you may hear a noise for a short
while until the DTS decoder recognizes the DTS-encoded
signal and starts operating. This is not a malfunction.
• If you press the PAUSE or SKIP button on the player while
playing a DTS source, a short noise may be heard. This is not a
malfunction. In such cases, try playing the source in the “DTS”
selected.
• The DTS indicator on the TX-DS989 lights while a DTS
source is played. When playback finishes and the DTS signal
transmission stops, the TX-DS989 remains in DTS mode and
the DTS indicator remains lit. This prevents noise when you
operate the PAUSE or SKIP button on the player. Therefore, if
the source is immediately switched from DTS to PCM, the
PCM signal may not be played. In this case, stop the playback
of the source on the player for about three seconds and then
resume playback.
Input Setup
• You may not be able to play some DTS source signals from
certain CD players and LD players even if you connect the
player to the TX-DS989 digitally. This is because the digital
signal has been processed (such as the output level, sampling
frequency, or frequency response) and the TX-DS989 cannot
recognize the signal as DTS data. Therefore you may hear
noise when you play a DTS source while processing the signal.
• The outputs for the VIDEO 1 OUT, VIDEO 2 OUT, TAPE 1
OUT, and TAPE 2 OUT output analog audio signals. Do not
record from CDs or LDs that support DTS using these outputs.
If you do, the DTS-encoded signal will be recorded as noise.
