ELAC SUB 2090 Bedienungsanleitung Seite 25

7. DELAY
The "DELAY" parameter allows you to set a delay time for the music signal before it is
played back through the subwoofer. This feature is particularly useful, for example, if the
subwoofer has to be placed nearer to the listening position than the main loudspeakers.
Increasing the delay time by 1 millisecond ("msec") will have the same effect as moving
the subwoofer approximately 33 cm further away from the listening position. Conse-
quently, a setting of 20 milliseconds would be equivalent to increasing this distance by
approximately 6.6 meters.
If you are using a surround-sound amplifier equipped with an automatic calibration
function, it will automatically set the delay time internally. In this case, you should set the
delay for the subwoofer to minimum.
8. AUTO EQ
Your subwoofer is equipped with an automatic calibration function. This activates the
subwoofer via the APP and instructs it to play back the measurement signals and uses
the built-in microphone in your smartphone to record the measurement curve.
Automatic room calibration is performed in 2 steps, the first of which involves calibrat-
ing the measurement environment, i.e., the microphone and the sound reproduction
chain. In step 2, the actual room frequency response is measured.
Follow the instructions in the APP to carry out a successful measurement.
