Bass Focus

The time difference between the front-rear/left-right speakers, can be adjusted at the same time. With an initial delay of 0.3 ms for each of the 0 to 39 steps, audible time correction can be done. For finer adjustment, use the procedure in the previous section "Time Correction," for which the delay steps are 0.1 ms.

1 Press the T.CORR button to select the Bass Focus mode.

Example of Steps 2 and 3 Setting

(1)After entering corrections for the front (left and right) speakers in STEP 5, the time difference is 1.5 ms for both front-left and front-right speakers.

1.5ms1.5ms

(2)After entering corrections for the left (front and rear) speakers in STEP 5, the time difference becomes 3.0 ms* for the front left speaker and 1.5 ms for the left rear speaker.

* Because the time difference was already set to 1.5 ms for the front left speaker in STEP 1, the additional correction in STEP 5 makes the time difference of the front left speaker 3.0 ms.

3 Turn the Rotary encoder to adjust the front-rear / left- right delay.

4 For setting another channel (speaker), repeat the steps

2 and 3.

5 After setting, press the T.CORR to return to the normal mode.

NOTES

Any manual time correction adjustments will also affect corrections made in Bass Focus. However, since the interval of the manual mode is 0.1ms and that of Bass Focus is 1 step (0.3ms), some difference may occur.

Time Correction mode is automatically canceled if no buttons are pressed within 15 seconds.

Tips

*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 above, you can change the positions of left and right speakers by delaying the time .
