This patent-pending feature defeats the calibration that would normally be set for the Subwoofer by the external calibration, allowing MultEQ Pro to set the filter for the subwoofer instead. The other surround channels are still able to be calibrated normally by the external calibration method.

THX position, or at 12 o’clock on a conventional level control. Phase controls, if they exist, should be set to 0° . Defeating the lowpass filter in the subwoofer ensures that the MultEQ Pro software has the best possible chance of producing the smoothest response through the crossover region.
The MultEQ Pro Application Overview and Screen Sequence The MultEQ Pro application consists of a series of screens which leads installers through the calibration process. The names of each screen are listed in the left column of the application (A, C) to help track progress.
Product Selection Choose Audyssey Sub Equalizer from the list of Audyssey products and press the ► button to continue. MultEQ Pro supports multiple products from various manufacturers. Many of the MultEQ Pro screens that follow are common to most Audyssey Installer-Ready products. Some screens and elements within may vary so it is important to review the each product’s User Guide.
As part of preparing the Installer Kit, Audyssey measures each microphone individually and stores a unique calibration file on each MultEQ Pro application CD. This file ensures that the MultEQ Pro room correction filters take into account the frequency response variations of each individual microphone used for calibration.
Input the dimensions of the customer’s room by clicking the up/down arrows next to each data field. Select from English or Metric units (feet or meters). The information entered at this screen is stored on the Audyssey Installer Website account and will not affect filters created or saved to the Sub Equalizer.
Equipment Info Enter information about the customer’s audio equipment. The information entered at this screen is stored on the Audyssey Installer Website account and will not affect filters created or saved to the Sub Equalizer. The information is stored for each individual calibration, and zone calibration.
If the AVR or Pre/Pro within the system does not have an Auto EQ feature, uses any type of Audyssey room calibration (2EQ, MultEQ, MultEQ XT, or MultEQ Pro), or you do not plan on using its auto EQ feature, skip this step.
Page 20 Channel Configuration The Audyssey Sub Equalizer has been designed to work within most home theater setups that use one or more powered subwoofers. It is important to understand and consider each of the various ways to configure the Audyssey Sub Equalizer.
3) When level matching the subwoofer pair, some conditions need to be taken into account that are not handled explicitly by the level matching routines. For more information, see Level Matching Subwoofer Groups, page 23. MultEQ Pro User Guide for the Audyssey Sub Equalizer Page 21...
Connections from the Sub Equalizer output to the SAT channel, the subwoofer(s) line level input on the plate amp to the Sub Equalizer, and the Audyssey Professional Microphone to microphone preamplifier and Sub Equalizer should already be in place. If you have not made any of these connections, refer to page 10 for connection steps.
A red color indicates that the current measurement is not within ±3 dB of Reference Level and still requires adjustment. When MultEQ Pro detects that the correct level has been achieved, the next included subwoofer may be selected and measured in the same manner.
Audyssey MultEQ Pro User Guide for the Audyssey Sub Equalizer Page 24 Measurement Before Measurements Review the following guidelines: Some subwoofers have a standby mode. Be sure to turn this function off before measuring (see Before the MultEQ Pro Calibration, page 13) The microphone should be placed in a vertical position (grazing incidence) for all measurements.
It is required to measure a minimum of three positions before continuing. Audyssey strongly recommends measuring at least 8 positions for average-sized rooms. Stagger the height of the microphone by a few inches from one measurement position to the next to account for the varying heights of listeners.
This is due to the delay that the subwoofer low-pass filtering circuitry introduces. Although the physical distance may be shorter, the MultEQ Pro-measured distance is in fact correct because it is measuring the total delay (acoustical and electrical) that the low frequency signal experiences.
