Bass Focus
The time difference between the front-rear/left-right
speakers, can be adjusted at the same time. With an
initial delay of 0.1 ms for each of the 0 to 99 steps,
audible time correction can be done.
1 Press the T.CORR button to select the Bass Focus
mode.
2 Press the BAND button to select the front-rear / left-
right speakers.
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 and hold the T.CORR button for at
least 3 seconds to return to the normal mode.
NOTES
• Any manual time correction adjustments will also affect
corrections made in Bass Focus.
• Bass Focus mode is automatically cancelled if no buttons
are pressed within 15 seconds.
• When the ALPINE Digital Audio Processor is connected to
the Digital Output Connector, the Equalizer, Crossover, Bass
Focus, Time Correction and MX (Media Xpander) functions
cannot be used in the built-in CD mode.
The functions on the connected Digital Audio Processor side
take preference.
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 .
