Input Setup
a. Digital Input
This setting tells the TX-DS787 which input source button on the
front panel is connected with which digital input jack on the rear
panel. To perform this setting, you must first select a digital input
source at the front panel and then set the name of the digital input
jack it is connected to here.
For example, if the input source selected at the front panel is CD
and the compact disc player is connected to DIGITAL INPUT
(OPTICAL) 1, then select “OPT1” here. If the input source
selected is not connected to a digital input, then select “----.”
OPT1: Select if connected to DIGITAL INPUT (OPTICAL) 1.
OPT2: Select if connected to DIGITAL INPUT (OPTICAL) 2.
COAX1: Select if connected to DIGITAL INPUT (COAXIAL) 1.
COAX2: Select if connected to DIGITAL INPUT (COAXIAL) 2.
––––: Select if the input source is not from a digital input jack.
Note:
Do not assign a digital input to more than one input source. If you
are making a digital connection that requires you to change the
default settings, be sure to always first cancel the current digital
input setting and then assign the new setting.
b. Digital Format
The default setting is “All.” If “----” is selected for this input
source at the Digital Input setting, then this setting will not appear.
Although you can use this default setting as is, you may change it
as desired depending on the input signal format (e.g., if you know
that you will always be listening to a certain input signal format
from a particular input source).
All: Select for automatic detection of the input signal format. The
input signal format (Dolby Digital, DTS, PCM or Analog)
used by the selected input source is detected automatically to
execute the required 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.
Note:
If “All” 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.”
Notes on DTS:
• If you play a CD or LD that supports DTS when the “PCM”
setting is selected on the TX-DS787, 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 “All” 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 “All” 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-DS787 lights while a DTS
source is played. When playback finishes and the DTS signal
transmission stops, the TX-DS787 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.
• 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-DS787 digitally. This is because the digital
signal has been processed (such as the output level, sampling
frequency, or frequency response) and the TX-DS787 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
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.
• If a compact disc or LD encoded in the DTS format is played
back with “PCM” selected, only noise will be produced.
Always select “All” or “DTS” when playing back DTS-
encoded sources.
c. Multichannel
This sub-menu will not appear if AM or FM is selected at the front
panel for the input source. This setting is normally set to “No,” and
only needs to be changed to “Yes” if a DVD player, MPEG
decoder, or other component that has a multi channel port is
connected to the MULTI CHANNEL INPUT port for 5.1-channel,
6.1-channel, or 7.1-channel audio. For example, if a DVD player is
connected to the MULTI CHANNEL INPUT port, then select
DVD at the front panel as the input source, bring up this sub-menu,
and select “Yes” for the Multichannel setting. You can only select
Multichannel with the AUDIO SELECTOR button when “Yes” is
selected here.
Note:
When playing a device that is actually connected to the MULTI
CHANNEL INPUT terminal, select Multichannel with the
AUDIO SELECTOR button.
