4. Basic operation
4.1. Bypass mode
If you want to compare the corrected and uncorrected operation, press the
BYPASS button quickly. This will switch between bypass and normal mode. The
first press will put the Anti-Mode into bypass mode, which is also indicated by the
BYPASS LED being lit. If the Bypass mode is already active, the unit switches back
to normal mode. In bypass mode no room corrections are active and user selected lifting EQ
is turned off.
4.2. Lifting EQ
The LIFT button switches between the EQ settings of the Anti-Mode 8033. The settings are
stored with a longer press of the LIFT button. A brief sound heard from the subwoofer after
settings have been stored indicates that you should release the LIFT button.
4.2.1. Flat
The first EQ setting is “flat” or no lifting. Neither the LIFT25 nor LIFT35 LED are lit.
In this setting, the target response is flat from 5Hz to 160Hz. This setting is
automatically changed to Subsonic-Filter-Only after the first (main) calibration. You
can override this and save the new setting.
4.2.2. Lifting 15-25Hz
The second EQ setting is LIFT25. When the LIFT25 LED is lit, the Anti-Mode boosts
frequencies between 15 and 25Hz (max. 8dB at 20Hz). This will also activate a
digital infrasonic filter, which will filter out frequencies below 10Hz, which can be
dangerous to ported subs without proper protection.
4.2.3. Lifting 25-35Hz
The third EQ setting is LIFT35. When LIFT35 LED is lit, the Anti-Mode boosts
frequencies between 25-35Hz (max. 8dB at 30Hz). As with LIFT25, the digital
infrasonic filter is also activated.
4.2.4. Subsonic Filter Only
A fourth EQ setting activates the digital subsonic filter without any lift. The
Subsonic-
Filter-Only
mode is active when the LIFT25 and LIFT35 LEDs are dimly lit. The “flat”
setting is automatically changed to this setting after the first (main) calibration.
All lifting modes decrease the overall level of the signal by 3 dB to reduce the risk of
clipping / saturating the output signal. Listening tells you which one of the lifting
settings gives best results. The 'flat' and 'subsonic-filter-only' settings are probably
the best options for music, because they give the most accurate transient response.
