    Level warnings create an irregular flickering of the respective LEDs. In calibration and low-pass filter selection mode the LEDs flash on and off in a steady pace. Anti-Mode 8033 cinema has yellow LEDs by default. Anti-Mode 8033S-II has blue LEDs by default.

  • Page 6: Quick Setup Guide

    8033 / 8033S-II CINEMA 2. Quick Setup Guide 1. Please read the rest of the manual to get the most out of your system and the Anti- Mode 8033. 2. Connect the subwoofer signal to "LINE IN" (LEFT input on the 8033S-II). 3.

  • Page 7: Before Calibration

    8033 / 8033S-II CINEMA 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.

  • Page 8: After Calibration

    8033 / 8033S-II CINEMA 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).

  • Page 9: Subwoofer Placement

    8033 / 8033S-II CINEMA 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).

  • Page 10: Multiple Subwoofers

    8033 / 8033S-II CINEMA 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.

  • Page 11: Strategy 1, "Compensation Of The Worst Response Point

    8033 / 8033S-II CINEMA 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.

  • Page 12: Basic Operation

    8033 / 8033S-II CINEMA 4. Basic operation 4.1. Bypass mode If you want to compare the corrected and uncorrected operation, press the BYPASS BYPASS button quickly. This will switch between bypass and normal mode. The LIFT 25 LIFT 35 first press will put Anti-Mode into bypass mode, which is also indicated by the BYPASS LED being lit.

  • Page 13: Subsonic Filter Only

    8033 / 8033S-II CINEMA 4.2.4. Subsonic Filter Only A fourth EQ setting activates the digital subsonic filter without any lift. The Subsonic- BYPASS Filter-Only mode is active when the LIFT25 and LIFT35 LEDs are dimly lit. The “flat” LIFT 25 LIFT 35 setting is automatically changed to this setting after the first (main) calibration.

  • Page 14: Output Level Warning

    LED starts to flicker, and you should decrease the Anti-Mode 8033 input level or turn off lift mode. 4.5. Powering Up and Down Anti-Mode 8033 cinema and Anti-Mode 8033S-II have almost no power-on and power-off transients, so you can easily power them on and off using a switchable power cord or the switchable power output from your AVR.
  • Page 15 8033 / 8033S-II CINEMA 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.
