When DTS program material ends and the DTS
bitstream stops, the AV receiver remains in DTS
listening mode and the dts indicator remains on. This
is to prevent noise when you use the pause, fast
forward, or fast reverse function on your player. If
you switch your player from DTS to PCM, you may
not hear any sound because the AV receiver does not
switch formats immediately. In such 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.
