[. . . ] 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 g or f to select the Bass Focus mode. Bass Focus mode Time Correction mode *1 3 4 *1 Subwoofer speaker. You cannot change the Time Correction value for the subwoofer, but you can set the subwoofer's apparent position to the front by adjusting the Time Correction value of the front and rear speakers. The sound is not balanced because the distance between the listening position and the various speakers is different. The difference in distance between the front left speaker and the rear right speaker is 1. 75 m (68-7/8"). Here we calculate the time correction value for the front left speaker in the diagram on the above. Press BAND/TEL. to select the speakers to be adjusted (see below). FL RL FR RR FL RL FR RR Front (left-right) speakers Left (front-rear) speakers FL FR RR Conditions: Farthest Speaker ­ listening position : 2. 25 m (88-9/16") Front left speaker ­ listening position : 0. 5 m (19-11/16") Calculation: L = 2. 25 m ­ 0. 5 m = 1. 75 m (68-7/8") Time correction = 1. 75 ÷ 343*2 × 1000 = 5. 1 (ms) FL RL FR RR RL *2 Speed of sound: 343 m/s (765 mph) at 20°C In other words, giving the front left speaker a time correction value of 5. 1 ms makes it seem as if its distance from the listener is the same as the distance to the farthest speaker. Time correction eliminates the differences in the time required for the sound to reach the listening position. The time of the front left speaker is corrected by 5. 1 ms so that its sound reaches the listening position at the same time as the sound of other speakers. Rear (left-right) speakers Right (front-rear) speakers 5 6 7 Turn the Rotary encoder to adjust the delay (see Time Difference Table). Press the Rotary encoder to confirm the adjusted contents. The adjusted contents are not stored if the Rotary encoder is not pressed. 18-EN 8 After setting, press and hold MENU for at least 2 seconds to return to normal mode, or press MENU and select RETURN to return to normal mode.

The time difference is 3. 0 ms*2 for the front left speaker, and 1. 5ms for the left rear speaker, creating the impression of an equal listening between the front left speaker and the other speakers. 25 26 27 28 29 30 31 32 33 34 35 36 3. 0ms 1. 5ms 1. 5ms 37 38 1. 5ms 39 40 41 42 43 44 45 46 47 1. 5ms *1 *1 Subwoofer speaker. Delay (turn the rotary encoder) the audio signal to the front (left and right) speakers to make the apparent position of the subwoofer to be at the front. In doing this, the apparent position between the front (left and right) speakers and subwoofer will appear equal to the driver. After performing the above, you can change the positions of the left and right speakers by delaying the time . *2 Because the time difference was already set to 1. 5ms for the front left speaker to begin with, the additional correction of 1. 5ms makes the total time difference of the front left speaker 3. 0ms. 48 49 50 19-EN Adjusting and Storing the Time Correction Before performing the following procedures, refer to "About Time Correction" (page 18). Setting the MX Mode MX (Media Xpander) makes vocals or instruments sound distinct regardless of the music source. The FM radio, CD, and MP3, will be able to reproduce the music clearly even in cars with a lot of road noise. 1 2 3 4 Press and hold MENU for at least 2 seconds.
