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.

1.5ms1.5ms

(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*1 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.
