This difference in the distances from the speakers to the listener creates a shift in the sounds image and frequency characteristics. This is caused by the time delay between the sound reaching the listener's right versus the left ear. To correct this, the CDA-9831R/CDA-9830R is able to delay the audio signal to the speakers closest to the listener. This effectively creates a perception of increased distance for those speakers. The listener can be placed at an equal distance between the left and right speakers for optimum staging. The adjustment will be made for each speaker in 0. 1 ms steps. Example 2. Listening Position: All Seats Adjust the time correction level of each speaker to almost the same level. 1 2 3 Sit in the listening position (driver's seat, etc. ) and measure the distance (in meters) between your head and the various speakers. Calculate the difference between the distance to the farthest speaker and the other speakers. L = (distance to farthest speaker) ­ (distance to other speakers) Example 1. Listening Position: Front Left Seat Adjust the time correction level of the front left speaker to a high value and the rear right to zero or a low value. Divide the distances calculated for the speakers by the speed of sound (343 m/s (765 mph) at 20°C). These values are the time correction values for the different speakers. Bass Focus The time difference between the front-rear/left-right speakers, can be adjusted at the same time. With an initial delay of 0. 1 ms for each of the 0 to 99 steps, audible time correction can be done. 5. 1ms 0. 5m 2. 25m 1 2 *1 Press and hold MENU for at least 2 seconds. Press MENU to select T.
