Velodyne Acoustics SPL-1200R - Manual (Page 11)

POWER
This button forces your SPL-R unit into standby mode. The
woofer will not play and the LED will turn off. The unit will remain
in this mode until the POWER button is pressed again. To fully
deactivate (i.e. power down) the unit, turn off the power switch on
the back panel.
MUTE
This button mutes the subwoofer. The light on the subwoofer will
blink slowly if the unit is muted. To unmute the subwoofer, press
the MUTE button again.
EQ
This button automatically EQs the subwoofer using a 6-band
internal graphic equalizer. To use this feature, first plug in the
supplied microphone into the Mic In jack on the back panel of the
subwoofer and place the mic in your preferred listening position.
Then, by pressing EQ on the remote, the subwoofer emits 12
“sweep tones” that cover the frequencies between 20 and 150
Hz. After the sweeps are complete, the unit saves its EQ settings
and returns to normal operation. In order to avoid accidentally
activating the EQ feature, you will need to hold down the EQ
button for 1 to 2 seconds before the EQ sweep tones activate.
NOTE: Each time the EQ feature is utilized, the EQ settings for the
SPL-R are reset. If the microphone is not plugged in, the SPL-R
will emit a single sweep tone then cease the EQ operation. In this
case, the previous EQ settings will be preserved.
PHASE
These buttons allow you to optimize the subwoofer performance
for the location and your listening position. Select the switch
position at which you hear the most bass. The light will blink
according to the following schedule:
0 degrees 1 blink
90 degrees 2 blinks
180 degrees 3 blinks
270 degrees 4 blinks
LIGHT
If you wish, you can deactivate the blue front panel light on your
SPL-R unit. To do this, press the LIGHT button on your remote.
The light will turn off. To reactivate the light, press the LIGHT
button again.
