Important! If only one sweep signal was generated during the calibration, one of the following

situations occurred: the microphone was not properly connected, the calibration signal was

not detected, or the calibration was aborted. If only two sweeps were generated, perhaps

both buttons on the front panel were not pressed. In any case, the calibration process must

be restarted.

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). Without a sub EQ device, you need to locate

the subwoofer in a place that creates the flattest possible response in your room.

This is not what you want with the Anti-Mode. With the Anti-Mode you do not need to be

concerned about room modes because they are easily and effectively corrected. Instead,

you should concentrate on minimizing the number of nulls, because these cannot be

corrected by a sub EQ device.

If you are not happy with your subwoofer performance in its current location, try locating the

subwoofer in a corner. This causes the room modes to be excited maximally, but reduces the

occurrence of nulls. The boundary reinforcement from the corner walls also allows the sub to

reproduce lower frequencies without using extra power. Run the Anti-Mode calibration after

relocating the subwoofer.

Therefore, what was once considered the worst place to locate a sub is now the best place

when using the Anti-Mode!

2.5. Cross-Over Frequency

The appropriate cross-over frequency to use depends on the capabilities of the subwoofer

and main speakers. For best results, the main speakers should be set to 'small' in the AVR

so only the subwoofer that has its response corrected is reproducing the low frequencies.

With the Anti-Mode the subwoofer integration through the AVR should be more effortless.

You are now able to use a higher cross-over frequency than the standard 80Hz setting

without the sub becoming localizable. We recommend trying 100Hz or 120Hz cross-over

setting but because there are varying differences between individuals, let your ears decide

which setting is best for you.

2.6. Multiple Subwoofers

Having multiple subwoofers reproducing the same signal (dual mono) will result in a

smoother response. The 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. The Anti-Mode takes this into account, creating a smoother overall

response than if the subs were calibrated separately.

If you want to reproduce low frequencies in stereo, you need either two Anti-Mode 8033's or

one Anti-Mode 2.0 Dual Core. Stereo at low frequencies is generally not needed, because

low frequencies are omnidirectional and directional cues are determined from harmonics and

other aural information. It is usually better to use the dual mono arrangement instead of

stereo to get a more even response.
