    Perfection in sound can only be achieved through the mastery in the art of room acoustics! We have worked hard to ensure that the Anti-Mode 2.0 Dual Core is not only powerful and versatile but also intuitive and easy to use. However, it is a good idea to read this manual in whole before operating the unit.

    2.0 D WNER ANUAL EXAMPLE: Adding a -3dB treble tilt-down above 5 kHz Background: Some recordings seem too bright or 'toppy' in their tonal balance. To compensate this the high frequencies can be toned down using a subtle high frequency attenuation filter. How to do it step-by-step: ➢Open main menu by pressing the MENU button.

  • Page 15: High/Lowpass Filters

    ANUAL High/Lowpass filters The Anti-Mode 2.0 Dual Core features fully customizable highpass and lowpass filters. These filters can be used to control the pass-band of the speaker or subwoofer. For example, with a custom lowpass, it is easy to implement a more precise digital cross- over filter for a subwoofer.

  • Page 17 2.0 D WNER ANUAL EXAMPLE: Adding a psycho-acoustic 3 kHz dip Background: The idea behind making a 3 kHz dip originates from the human auditory system and diffuse field characteristics. The human hearing is less sensitive to diffuse fields in the neighborhood of 3 kHz. Because of a flat microphone response, compared to the original listening situation for example in a concert hall, many recordings have too much energy around 3 kHz.

  • Page 18: Digital Headroom (Advanced)

    2.0 D WNER ANUAL Digital Headroom (Advanced) All internal digital processing is performed with 32- or 40-bit accuracy with the appropriate number of bits reserved for headroom. However, if emphasizing (raising) filters are used, some input signals could cause saturation / clipping at the output. The unit automatically calculates the best headroom setting from the gains of the active filters.

    By selecting “PC Link”, you can export the measurements of the currently selected profile to a PC or Macintosh computer via USB. Anti-Mode 2.0 Dual Core will appear as a removable disk and you can copy the measurements as text files that can be imported to popular PC / MAC measurement programs.

  • Page 20: Using Sound Profiles

    ANUAL 5.Using Sound Profiles Anti-Mode 2.0 Dual Core supports up to four independent sound profiles. A sound profile includes everything that affects the sound: the room correction filters and all possible custom filters (highpass/lowpass filters, house curve etc.) Also all room measurements are stored in the profile.

    2.0 D WNER ANUAL 6.Advanced Calibration Advanced calibration gives the user more control over the calibration parameters. The procedure is similar to the typical calibration, but with some additional steps. Refer to ”Typical Calibration” section of this manual for an overview of the basic process. To perform the advanced calibration, choose the Advanced Calibration option at the Calibration menu.

    ✗”Clipping Detected”: this warning is displayed at the home screen in two cases. 1.”Clipping Detected” is shown when Anti-Mode 2.0 Dual Core detects that the analog input signal has reached the maximum input voltage level, causing the input to be clipped.
  • Page 26 WNER ANUAL Check the output settings of the device you have connected to the Anti-Mode 2.0 Dual Core analog inputs. If you can not reduce its output level, check that the input sensitivity is set to low in the ”Audio Settings” menu. If this does not help, you can try using the RCA inputs instead of XLR inputs.
