orange) will be shown in white as the current values and there will be no values
displayed in orange.

Setup with a Real Time Analyzer (RTA) calibration tool (without Lip Sync Offset)

1. Pick an ideal central location on which all speaker output signals converge.
2. Place the microphone from the RTA at ear level in the convergence location.
3. Play the audio source. This can be an analog source, provided by the RTA, or a
digital source, provided by a test CD.
4. Use the Test Signal Output buttons in the Testing and Trim Tab (see page 5-12)
to select which speakers will be tested and the order in which the speakers will
be tested.
5. Use the RTA to measure the Speaker Distance (in ms) for each channel.
6. In the SSP 7.1 Setup and Control Software Speaker Delay tab, check the
milliseconds (ms) button and enter the values for each speaker (in ms) into the
boxes. The up/down (
7. Repeat steps 4 to 6 until the speaker distance
has been entered for all available speakers.

Compensating for Lip Sync Offset

Lip Sync Offset compensates for a lack of
coordination between the audio and the
accompanying video signal (see page 4-5). Enter
the appropriate value in the Lip Sync Offset box. This delay is added to every
available speaker to resynchronize the video and audio signals.
N The total speaker delay (Compensation Delay + Lip Sync Offset) must not
exceed 100 ms.
