Lip Sync (STR-DA5000ES and DA9000ES)
Today's advanced televisions and video projectors often incorporate
sophisticated video signal processing to optimize the image quality. Often, these
circuits require buffer memories that result in a slight delay of the video signal.
Unfortunately, this can result in a mismatch, where the television picture lags
behind the sound from the speakers by some fraction of a second. As you can
imagine, the effect can be unnatural and annoying.
That's why Sony provided the STR-DA5000ES and DA9000ES with Lip
Sync. This circuit enables you to correct time misalignments between the audio
and video signals by up to 200 milliseconds, in 10 millisecond increments. This
brings your television and your home theater speakers back into alignment. This
Lip Sync is performed uniformly on stereo, 7.1-channel and even digital audio
inputs.
The STR-DA5000ES performs Lip Sync with another Sony Large Scale
Integrated circuit, the CXD9722.
9.1-Channel Operation (STR-DA9000ES)
The STR-DA9000ES offers an ingenious arrangement of the A and B
speaker terminals. The speaker selector switch includes positions for A, B and A
+ B. In the A + B position, the receiver can drive two Surround Left and two
Surround Right speakers, in addition to a Surround Back pair. Of course, this 9.1
configuration is closer to the array of surround speakers used in a commercial
movie theater. It's also exactly the same as the 9.1-channel configuration of
Hollywood dubbing theaters!
