When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listen-
ing mode and the DTS indicator remains on. This is
to prevent noise when you use the pause, fast for-
ward, or fast reverse function on your player. If you
switch your player from DTS to PCM, because the
AV receiver does not switch formats immediately,
you may not hear any sound, in which case you
should stop your player for about three seconds, and
then resume playback.
—
With some CD and LD players, you won’t be able to
playback DTS material properly even though your
player is connected to a digital input on the AV
receiver. This is usually because the DTS bitstream
has been processed (e.g., output level, sampling rate,
or frequency response changed) and the AV receiver
doesn’t recognize it as a genuine DTS signal. In such
cases, you may hear noise.
—
When playing DTS program material, using the
pause, fast forward, or fast reverse function on your
player may produce a short audible noise. This is not
a malfunction.
—
Since it takes longer to identify the format of an
HDMI signal than it does for other digital audio sig-
nals, audio output may not start immediately.
