APPENDIX C: PRODUCT INTEGRATION
PRODUCT INTEGRATION
Product Integration combines both Delay Integration and Starting Point settings in a single dialog. Using Product Integration
is the first step to complete when optimizing a system. It is not recommended for use when a system has previously been
optimized, as some or all of the output processing filters and settings may be over-written.
By selecting the loudspeaker model in the pop-up window, the Delay and Starting Point drop-down menus are populated
with the available options.
A video describing Product Integration in more detail is available at https://meyersound.com/videos/#support
Delay Integration
Delay Integration aligns the phase responses of different loudspeaker model families to match predefined target curves.
After selecting the product this setting will apply to, choose the desired target phase curve frequency: 55-70, 100, or
125 (Hz). Different products will have different phase curve options available, though PC125 will be available for every
product. Choose the lowest target phase curve that is available for all loudspeaker types in a system.
Some subwoofer Delay Integration settings also implement filters that change the frequency response of the product. This is
necessary to achieve the appropriate phase response to be compatible with the phase curve family.
Starting Points
Starting Points includes two types of settings: the first are filter presets for line array models, the second are delay and
polarity settings for the rear-facing element(s) of gradient subwoofer arrays.
Line Array Models
When certain line array products are chosen, the user can select a Starting Point from the drop-down menu. These presets
use U-Shaping filters that adjust the frequency response to a usable result. For most products, the response will be close to
equal magnitude (flat) for arrays that are 6-8 elements.
Some line array products have presets that are based on the total splay angle between four elements, shown as “Wide,”
“Medium,” or “Narrow.” Choose the setting that best matches the splay angles between the elements this output channel
will be driving.
For example, if an output will be driving four elements of a LYON-M array where there is 3° of splay between every element,
the total splay between four elements is 9°, and the “Medium” preset would be most appropriate.
Some line array products have a single preset that can be used as a starting point in any configuration. If a line array product
does not have an Starting Point preset available, it is designed to be used in Native Mode and does not require a preset. For
more information about Native Mode, consult the User Guide for that product.
Subwoofers
Starting Point settings for some subwoofers provide a choice to select a front- or rear-facing subwoofer. These settings are
designed for subwoofers being used in gradient configurations that produce cardioid coverage patterns. Selecting a
“Front Facing” Starting Point will not implement any processing for most models. Selecting a “Rear Facing” Starting Point
will invert the polarity and implement appropriate delay to synchronize the output of the rear-facing element with the output
behind the array of the front-facing elements. This delay is applicable to subwoofers that are physically reversed in an array
or ground-stack.
