FEATURE UPDATE - INSTALL MARKET July 1, 2021

Information:

JBL DSi2.0 Firmware version 9.0.0.0(Install market specific firmware) now allows customers to use DSI 2.0 amplifiers for a broader range of applications.  This update is a standalone one -time only firmware solution that installs JBL SpeakerTunings forthe Install, PPA and Record and Broadcast range of loudspeakers to be used within the DSI 2.0 amplifiers via Audio Architect as well as the front panel of the Amplifiers.  There will be no other feature firmware updates above version 9.0.0.0 for the install market other than for critical issues.  Cinema market SpeakerTunings are removed as part of this update.

Note: This Firmware update should only be used for non-cinema applications.  Cinema users should continue to use the standard firmware updates available as part of Audio Architect to ensure that they continue to receive cinema specific feature updates.

As part of the update, JBL Speaker Tunings for Install, PA and Record and Broadcast market products within Audio Architect and the front panel UI are now enabled for the JBL DSi2.0 series of amplifiers.  The required files are available within the software package 'DSi2_Install_7_01_21' attached with this document.

This Document only outlines the changes impacted by the new Feature Update and MUST be used in conjunction with the User Manual found at https://jblpro.com/en-US/products/dsi-2-0-series#downloads

HI-Z SYSTEM OPERATION

The JBL DSi2.0 Amplifiers do NOT support Hi-Z operation natively. However, there are ways this can be achieved with some prior planning.
The SA4/SA4-D will support 70V when using the amplifier in bridged mode. Note: The SA4/SA4-D will NOT support 100V operation.
The MA4/MA4-D will support 70V/100V when using the amplifier in bridged mode.
The LA4/LA4-D will support 70V/100V operation on all 4 channels.
Since the amplifiers do not support Hi-Z operation natively, there are a couple of points to adhere to when using the DSI 2.0 for Hi-Z loads.

A High Pass Filter must be engaged to prevent Transformer saturation.  A Butterworth 24dB per octave filter at 35Hz must be used.

A RMS Level Limiter must be set in the Limiter section.  For 70V operation, the RMS Level must be set to 70V and for 100V operation, the RMS Level must be set to 100V.
