Speaker Tuning Panel
A new “speaker tuning” icon is implemented on the main device panel for each channel of DCi amplifiers. Double-clicking the speaker tuning icon will open the basic
Speaker Tuning Panel (STP).
Basic STP functions are:
Recall
Loads the selected tuning from the working library (drop-down list) into the respective channel.
Store
Stores the STP settings from the respective channel into the working library with specified user name. The stored tuning is then available in the drop-down list for any
other channel or amp.
Delete
Deletes the selected tuning from the working library.
Speaker Manufacturer
This parameter displays a text description of the respective speaker manufacturer (i.e.JBL, Custom, etc.). The data for this parameter is stored within the tuning and also
within the device settings.
Speaker Model
This parameter displays a text description of the respective speaker model (i.e.3722, Three-Way, etc.). The data for this parameter is stored within the tuning and also
within the device settings.
Band
This parameter displays a text description of the respective tuning band (i.e. LF, MF, HF). The data for this parameter is stored within the tuning and also within
the device settings.
Tool Tips
The Mfr, Model and Band text fields are displayed in the tool tip box when the mouse is hovered over the respective channel Speaker Tuning Icon.

Speaker Tunings
Crown and JBL engineers have designed DriveCore Install DSP settings that are optimized for various JBL loudspeakers. Speaker tunings can be downloaded at the
following website: www.jblpro.com. An improved speaker tuning approach has been developed for the DriveCore Install Network Series. The system is software library
based rather than device preset based. The new approach offers significant benefits:
• Unlimited number of tunings organized into an unlimited number of libraries
• Simple and fast drop-down tuning recall/store/delete within device GUI
• Channel/band specific tunings – no more managing tunings across channels or amp chassis. Also yields logical one-to-one correlation of amp output
to transducer/band.
• Faster tuning load/store times – much easier to compare and run A/B tests on multiple tunings without audio dropouts
• Library based – allows logical groupings and archiving of similar tunings (e.g. Screen Array Series or VTX Series, etc.)
• Tunings can be held within but are de-coupled from device presets. Eliminates concern of accidentally deleting or changing other device parameters –
speaker tunings only contain the parameters required for speaker tunings! Now presets can be used for complete device configurations – as intended.
• Simpler and faster third-party and user tunings and libraries development – more people will be willing to develop custom or 3rd party tunings
• Single panel access to all required tuning parameters – easier/faster to create/modify tunings.
