SpeakersThe Optimize Phase Speaker sub menu includes tabs for Power Shading, Application, Edit, Input EQ, and Dynamic EQ. Refer to Design Phase - Speakers for details about Power Shading and Application tabs. The Edit, Input EQ, and Dynamic EQ tab features are described below and offer a granular level of control for advanced and specific requirements.
The features detailed below covering the Edit, Input EQ, and Dynamic EQ tabs include a number of EQ panel menus. These menus function similarly to the EQ menus as seen in the Optimize Phase - EQ. The descriptions below detail the unique features of each of these menus and assume a familiarity with the basic use of EQ panel tools, charts, and adjustments.
Follow the links below to jump to the topics covered on this page:
Limiters - Threshold, Side Chain EQ RMS, Side Chain EQ Peak
Use the Edit Profile button on a speaker device to access the advanced speaker options control panel.
Hi Z Options panel is divided into 70 Volts Taps and 100 Volts Taps. This option isn't available when a speaker is in Low Z mode.
Power: Select the first checkbox to unlock the editable text field for Power. Each checkbox and text field becomes available once the line above it has been selected. The Power value of the first line is set automatically but may be edited. Each subsequent line selected will have a power value set to half of the proceeding line. Changing the value of a line will automatically update the value of each line after to half of the selected value but will not change the value of each line before it. Power is displayed in Watts.
Impedance: Once the checkbox is selected for a line the impedance value will be made visible. The text field is not directly editable but will automatically adjust to changes made to the Power text field on the same line or a line above. For Example, editing the Power value of line 3 will update the Power and Impedance for lines 4 and 5 but lines 1 and 2 will remain unchanged. Impedance is displayed in ohms.
Many of the features detailed below overlap with the options available in the Deploy Phase - Impedance action. See that section for additional information on specific options available there.
Per Cabinet Nom.Imp.: Adjust the Per Cabinet Nominal Impedance value to change the average impedance presented to an amplifier (range 2.6 - 999.0 ohms).
