ANTI-MODE 8033 CINEMA / 8033S-II 2. Quick Setup Guide 1. Please read the rest of the manual to get the most out of your system and the AntiMode 8033. 2. Connect the subwoofer signal to "LINE IN" (LEFT input on the 8033S-II). 3. Connect the active subwoofer to “LINE OUT” (or OUT 0°) output. 4. Connect the microphone plug to the "MIC" jack and place and fix the microphone as close to the listening position (head of the listener) as possible. Use of a microphone stand helps with correct microphone placement.
ANTI-MODE 8033 CINEMA / 8033S-II 2.1. Before Calibration If you have a small reflex subwoofer, decrease its volume before calibration. If the subwoofer has a built-in low-pass or other type of filter, it should be deactivated before the calibration process and re-activated after calibration. Cross-over and low-pass filters in the AVR do not affect calibration since they take place before the Anti-Mode 8033 in the signal chain.
ANTI-MODE 8033 CINEMA / 8033S-II If you initiate the calibration process by mistake, you can abort it by pressing either the LIFT or BYPASS buttons. This will restore your saved settings, including the lift settings (and other filter settings for the Anti-Mode 8033S-II). Calibration is automatically aborted after one sweep if the microphone is not connected properly, is faulty, or the calibration signal is not detected (for example, the subwoofer is not turned on).
ANTI-MODE 8033 CINEMA / 8033S-II Whenever the placement of the subwoofer or listening position changes (or the dipole correction has changed in Anti-Mode 8033S-II), the initial calibration should be performed again to ensure an optimal result. 2.4. Subwoofer Placement There are several opinions available on how to determine the best place for your subwoofer. Due to room reflections creating resonances, some frequencies are amplified (room modes / peaks) and some are attenuated (nulls / dips).
ANTI-MODE 8033 CINEMA / 8033S-II 2.6. Multiple Subwoofers Having multiple subwoofers reproducing the same signal (dual mono) will result in a smoother response. Anti-Mode can be used with any system allowing you to use corner placement of your subs. Connect the Anti-Mode to the signal going into each sub, and calibrate them together. When calibrated together, the nulls created by one sub are filled in by the other sub.
ANTI-MODE 8033 CINEMA / 8033S-II 3.1. Strategy 1, “Compensation of the worst response point” When the first (main) calibration is performed at the primary listening position or at the center of the listening area, you can then evaluate the result by listening at different positions around the room. If the result is not adequate at some location, that location can be used as a secondary calibration point. Also any location between the secondary point and the first point can lead to good results.
ANTI-MODE 8033 CINEMA / 8033S-II 4. Basic operation 4.1. Bypass mode PWR BYPASS LIFT 25 LIFT 35 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 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.
ANTI-MODE 8033 CINEMA / 8033S-II 4.2.4. Subsonic Filter Only PWR BYPASS LIFT 25 LIFT 35 A fourth EQ setting activates the digital subsonic filter without any lift. The SubsonicFilter-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. 4.2.5. Lifting 20-30Hz (Anti-Mode 8033S-II) PWR BYPASS LIFT 25 LIFT 35 The Anti-Mode 8033S-II has an additional EQ setting.
ANTI-MODE 8033 CINEMA / 8033S-II The level warning is also active during calibration. During calibration the output level is decreased automatically if needed (microphone is saturated). The LIFT25 LED flashes to indicate the progress of calibration. 4.4. Output Level Warning The new Anti-Mode correction will raise the overall level of the output depending on how drastic corrections were applied.
ANTI-MODE 8033 CINEMA / 8033S-II The filter selection mode is activated as follows. Activate bypass mode by pressing the BYPASS button. 1. Keep the LIFT button pressed until the power LED starts to flash, indicating filter selection mode. 2. A quick press of the LIFT button selects between the neutral mode and one of the 7 filter modes. The selected filter is immediately activated. 3. Keep the LIFT button pressed to save the filter selection.

ANTI-MODE 8033 CINEMA / 8033S-II 5. Connection Examples In a basic home cinema configuration, the Anti-Mode 8033 cinema or the 8033S-II is connected between the AVR / pre-amplifier and the subwoofer using line-level connections. The dual line inputs of Anti-Mode 8033S-II are used when connecting into a 2.1 stereo system which has only stereo preouts available (no dedicated LFE or sub output). Anti-Mode 8033 cinema can be used, but it requires an additional stereo to mono converter cable.
