(1) DSP On/Off Switch
This switch is used to enable or disable
the application controlled DSP. When
set to the OFF position, the frequency
adjustment knob will be active allowing
the user to make manual adjustments.
When enabled, make sure to adjust the
volume control to half level.
(2) Auto/On/Off Mode Switch
This is a 3-way switch. When ON, the
amplifier will remain on regardless of
signal presence. When set to AUTO, the
amplifier will only turn on when audio
signal is detected. Additionally, the am-
plifier will go to sleep/standby if it does
not detect any signal after 15 minutes.
When set to OFF, the amplifier will
remain off regardless of signal pres-
ence. Note that the MAIN POWER
switch must be in the ON position in
order for this feature to work.
(3) DSP LED
This LED indicator reflects the status of
the on board DSP. When the DSP switch
is set to the ON position the blue LED
indicator will illuminate. Please note
that while making any adjustments or
saving presets in the iWoofer
™
mobile
app, you may see flickering from this
LED indicator. This is considered nor-
mal as you are making on-the-fly adjust-
ments to the amplifier.
(4) Power & Signal LED
This LED indicator reflects the main
power status of the amplifier as well as
the state of the MiniMe DSP P63 ampli-
fier (whether the AUTO Sensing is
on/off and whether signal is being fed
to the amplifier). Note that this LED will
only illuminate when the main power
switch is set to the ON position.
(5) Volume Control
This rotating knob allows users to con-
trol the volume of the subwoofer. Al-
ways start at the lowest setting and
slowly increase the volume until the de-
sired subwoofer level is reached. When
DSP is enabled, adjust the volume con-
trol to half level.
(6) Phase Shift Control
This 0–180º switch allows the user to
synchronize the subwoofer to obtain a
better and more precise bass response.
(7) Low Pass Filter
A variable low pass filter from 40–180Hz
is designed to control the cutoff fre-
quency of the subwoofer. Any signals
above the set crossover frequency will
gradually roll off to prevent from inter-
fering with your surround speakers. For
2.1 channel audio systems, Earthquake
recommends that the filter be adjusted
to the 80Hz position. For any other au-
dio systems above 2.1 channels, it is
highly recommended that the filter be
adjusted to the 120Hz position.
