After setting, press MENU to select RETURN.
The unit returns to normal mode.
Pressing and holding MENU for at least 2 seconds will
return to normal mode.
• Any manual time correction adjustments will also affect
corrections made in Bass Focus.
• Bass Focus mode is automatically canceled if no operation is
performed within 15 seconds.
Example setting for steps 4 and 5
(1) Press BAND/TEL. to select the front (left and
right) speakers. Then turn the Rotary encoder to
select 1.5 ms (Delay no. 15 in the table). The time
difference is 1.5 ms for both front (left and right
speakers.
(2) Press BAND/TEL. to select the left (front and rear)
speakers. Then turn the Rotary encoder to select
1.5 ms (Delay no. 15 in the table). 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.
* 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 1.5 ms for the front
left speaker to begin with, the additional correction of 1.5 ms
makes the total time difference of the front left speaker 3.0 ms.
