Speaker Tunings
Speaker Tunings
The DCi DA amplifiers have a wide variety of onboard digital signal processing (DSP). The HiQnet Audio Architect software is used to adjust DSP settings.
Crown and JBL engineers have designed DriveCore Install DSP settings that are optimized for various JBL loudspeakers. Speaker tunings can be downloaded from
. The speaker tuning system is software library-based rather than device preset-based. This provides the following benefits:
• Organize an unlimited number of tunings into an unlimited number of libraries
• Recall, store, and delete speaker tunings quickly and easily
• Channel/band-specific tunings mean no more managing tunings across channels or amp chassis; this also yields a logical one-to-one correlation of amp output to
transducer/band
• Faster tuning load/store times, making it much easier to compare and run A/B tests on multiple tunings without audio dropouts
• Allows for logical grouping and archiving of similar tunings (e.g., Screen Array Series, VTX Series, etc.)
• Tunings are held within the amp but are de-coupled from device presets, eliminating the concern of accidentally deleting or changing other device parameters
• Speaker tunings only contain the parameters required for speaker tunings, allowing presets to be used for complete device configurations—as intended
• Simpler and faster development of third-party and user tunings and libraries, encouraging more people to develop custom or third-party tunings
• Single-panel access to all required tuning parameters, making it easier and faster to create/modify tunings
Speaker Tuning Panel
To open the Basic Speaker Tuning panel, double-click the
Speaker Tuning
icon for the desired channel from the Configuration panel (see
Figure 32:
Basic Speaker Tuning panel
Recall Button
This button loads the selected tuning from the working library (dropdown list) into the respective channel.
Store Button
This button stores the Speaker Tuning panel settings from the respective channel into the working library with a specified user name. The stored tuning is then available in
the list for any other channel or amp.
Delete Button
This button deletes the selected tuning from the working library.
Speaker Manufacturer Field
This field displays a text description of the respective speaker manufacturer (e.g., JBL, custom, etc.). The data for this parameter is stored within the tuning and also within
the device settings.
Speaker Model Field
This field displays a text description of the respective speaker model (e.g., 3722, 3-Way, etc.). The data for this parameter is stored within the tuning and also
within the device settings.
Output Band Field
This field displays a text description of the respective tuning band (e.g., LF, MF, HF). The data for this parameter is stored within the tuning and also within
the device settings.
Advanced Settings Arrow Button
This button expands the window to display the advanced speaker tuning parameters.
