8 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. 1.5ms 5ms *1 ) (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. 1.5ms 1.5m8 1.5ms 1.5ms *1 • Subwoofer speaker. Delay (turn the rotary encoder) the audio signal to thefront (left and right) speakers to make the apparent position of the subwoofer to be at thefront. 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 msfor thefront left speaker to begin with, the additional correction of1.5 ms makes the total time difference of thefront left speaker 3.0 ms.
