initial delay of 0.1 ms for each of the 0 to 99 steps,
audible time correction can be done.

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

Press the BAND button to select the front-rear / left-
right speakers.

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

For setting another channel (speaker), repeat the steps

NOTES

• Any manual time correction adjustments will also affect

corrections made in Bass Focus.

• Time Correction mode is automatically cancelled if no

buttons are pressed within 15 seconds.

Example of Steps 2 and 3 Setting
(1) After entering corrections for the front (left and right)

speakers in STEP 15, the time difference is 1.5 ms for
both front-left and front-right speakers.

(2) After entering corrections for the left (front and rear)

speakers in STEP 15, 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 15 makes the time difference of the
front left speaker 3.0 ms.

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 .
