This screen lets you specify the distance—in feet or meters—between the speakers
and the primary listener location (the so-called “sweet spot”). This is done to ensure
that the sound from all speakers reach the listener’s ears at exactly the same time.
Measure the distances and enter the values to the nearest half-foot (or nearest 0.15
meter); the software will calculate any necessary delays. Enter distances as
accurately as possible.
You may also enter the delays in milliseconds by using a Real Time Analyzer (RTA)
equipped to give a millisecond value from the time the sound was produced to the
time it reaches the listener’s position. One example of such a device is the Audio
Controls Iasys RTA.
Note that the delays are not sent automatically in Realtime Mode. Click on the
Send
button to transfer the delay settings to the device.
Room Calibration
Any listening/viewing area has its own characteristics that can affect the quality of
sound reproduction. The goal is to analyze the room and compensate for any
unwanted effects (such as reflections from hard surfaces, and resonance at particular
frequencies) so the listener hears what was intended when the material was recorded.
During room calibration, this screen lets you set the master volume (e.g., -10dB) and
then modify the gain of each speaker in the system to make the sound of each
speaker heard at the same level. Generally, a calibration level is chosen between
75dB and 85dB when playing Dolby Noise and all speakers are adjusted to the same
level. The zero button to the left of the Front Left slider resets all speaker sliders to
0.00dB; the Master Volume and LFE settings are not affected.
