■ About DTS signals

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

amalfunction.

■The beginning of audio received by an HDMI IN can’t be heard

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.
