Speaker Distances
The Speaker Distance settings help the sound from each speaker
arrive at the listening seat at the same time. This provides a much
more believable and immersive sound environment. Accurately
measure the distance from the center of each speaker to the
seated ear position of the main listening seat. Write each of these
distances down (select Imperial or Metric) and enter them into the
Concert XR series using this menu. Speakers not present (as you
entered in the Speaker Types menu) will be greyed out. If the Dirac
Live application has been used, the speaker distances can still be
entered and edited in this menu.
Speaker Levels
It is critical to properly match the levels from each speaker to achieve a correct
sound stage. The realism is totally lost if the footprints of a person walking
across the screen change in volume as they move from left to center to right.
We strongly recommend using a audio analyzer such as our SA-4100i for this
calibration. The levels are nearly impossible to judge by ear alone. Though not
as accurate as using the SA-4100i, you can use a sound level meter for this
adjustment.
With the internal test noise generator of the Concert XR series, adjust each
speaker for a sound pressure level (SPL) of 75 dB using a “slow” response time
on the SPL meter, placed at the main listening position at ear height.
You can use an External Test Tone from the currently selected HDMI input if
you prefer.
