Appendix G: Important Information
About LSR4300 Firmware
The LSR4312SP Subwoofer has Firmware Version 2.0 or later installed. If you plan to use the LSR4312SP with an
existing LSR4328P or LSR4326P Studio Monitor, the fi rmware in the LSR4328P and LSR4326P Studio Monitor must
be compatible. LSR4300 Studio Monitors produced prior to September 2006 have Firmware version 1.1 installed.
LSR4300 Studio Monitors produced after September 2006 have fi rmware version 2.0 or later installed. The enclosed
CD ROM includes the required fi les and procedure to update the fi rmware in your LSR4300 speakers to version 2.0
or later.
To determine if the fi rmware in associated LSR4300 speakers require an update, determine the fi rmware version
currently installed in each speaker using this procedure:
o Remove the power cord from the loudspeaker.
o Reconnect the power cord to the loudspeaker.
o Following a brief (2 second) start-up sequence, the front panel display will freeze for approximately 5 seconds
with all button LEDs illuminated and the fi rmware version displayed on the level meter. The fi rmware version
should be read as follows:
o The number of green LEDs to the left of the -15dB mark indicate the 1’s digit of the fi rmware version.
o The number of yellow LEDs to the right of the -15 dB mark indicate the 1/10ths digit of the fi rmware version.
o For example. Firmware v1.1 will be displayed as follows:
o Firmware v2.0 will be displayed as follows:
If your Studio Monitors have fi rmware version 1.1 installed, use the enclosed CD ROM to update each Studio
Monitor to version 2.0 or later. Before proceeding, read the READ-ME fi le on the CD ROM. Copy the contents of
the CD to a Macintosh computer with OS10.3 operating system (or later) or a PC with Windows 2000, XP operating
system (or later) . Click on the Flash Update application for Mac or Windows and follow the prompts.
Notes:
o Using LSR4300 speakers with differing fi rmware versions is not harmful to any of the speakers. However, some
features will not work correctly and system performance may be impaired.
o It is not necessary to update the fi rmware in any speaker unless you plan to use it with the LSR4312SP
Subwoofer and it has an incompatible fi rmware version. If an incorrect fi rmware type has been loaded, ie: if a
subwoofer has been fl ashed with LSR4326P or LSR4328P fi rmware or vice versa, upon power up all LEDs of
the display will fl ash, the LEDs to the left of -15 will be green. The LEDs to the right of the -15 mark will be red,
and all of the button LEDs will fl ash too. To resolve this error, disconnect and reconnect the power cable to the
speaker. Then perform fi rmware update procedure using the correct fi rmware type.
