Get rid of the bass-masking standing waves with DSP. Calibrate automatically with a single press of a button.
Anti-Mode 8033 is by far the most economical way to improve your audio system.
• Improves bass extension and sonic quality of virtually any subwoofer(s). Note: see info about dual subs further below.
• Affordable and easy
• plug and play: no expertise required to calibrate and use. Connect via RCA interconnects.
A typical listening space has room modes creating unwanted resonates in low frequencies. Because of this, even the best subwoofer may not sound good enough. Much of the audio content gets masked by the frequency peaks introducing unwanted sound characteristics such as "slowness" and "boominess". This problem is most pronounced when a subwoofer is placed close to walls or corners of the room.
The Golden Ear awarded Anti-Mode™ technology eliminates the resonances of the subwoofer in the room by equalizing both amplitude and time domain responses using accurate digital filter structures and anti-phasing technology. This way, the listener can hear clean and smooth bass down to the deepest frequency produced by the subwoofer. Transient response is also drastically improved in the process, making bass sound faster and more controlled.
Anti-Mode 8033 is very simple to use. The calibration process is completely automatic: it generates frequency sweeps to the desired listening position (or multiple positions) and measures, then corrects, for the subwoofer interaction with the room.
Anti-Mode 8033 utilizes regular RCA connectors. Input to the device is taken from the line level subwoofer output of the (pre-)amplifier. Output is connected to the line level input of the subwoofer.
Note: Connecting Dual Subs – there are two outputs from the 8033-SII. One is in phase and one is has inverted phase at 180 degrees. If you have two subwoofers with phase control, set Phase to 0 on the sub connected to the 0 output of the 8033 and set Phase to 180 on the subwoofer connected to the 8033’s 180 output. This way, both subs will be in phase. Otherwise, the 180 output will create bass cancellation. Alternatively, you can use an RCA Y-adapter from the 0 output of the 8033 and then connect your RCA interconnects to this to keep phase correct.
Further Notes: Dual Subs – Anti-Mode corrected dual mono vs stereo - Having multiple subwoofers reproducing the same signal (dual mono) will result in a smoother response in general. Connect the Anti-Mode unit 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 calibration takes this into account, creating a smoother overall response than if the subs were calibrated separately using multiple Anti-Mode units. 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. However, stereo at low frequencies is generally not needed because low frequencies are omnidirectional and predominantly mixed in mono. Any 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.
