About DTS signals

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.
