Installation Instructions & Release Notes Lexicon
This document contains installation instructions for the 960L Version 2.40 Software. It
describes updated and enhanced features of Version 2.40, and discusses items that did not
receive full coverage in the Owner’s Manual. Please refer to the 960L Owner’s Manual for
additional information.
INSTALLATION INSTRUCTIONS
Note:
Although the installer will preserve user registers, it is recommended to save them to a
floppy disk before making the upgrade. (See the section called Organizing Your Registers
in Chapter 4 of the Owner's Manual.) These saved user registers will be compatible with
the current version of software in the 960L. If necessary, saved user registers can be
loaded from the floppy disk to the Version 2.40 system. However, it is recommended to
save a copy of the current user registers in case it is ever desired to revert the system back
to its current version. (See Reverting to a Previous Software Version on page 6.)
Performing this upgrade is a simple process. But to avoid problems, please follow the
instructions carefully. Pay particular attention to precautions that appear throughout this
document.
Please note the following before proceeding to the steps below:
• The installation process requires the 960L serial number, which is located on the back of
the mainframe. It is recommended to note the serial number before beginning
installation.
• The installation process will take approximately 15 minutes.
1. While the 960L is powered up, insert the Version 2.40 CD. Power down the system, wait
a few seconds, then power back up. After a few minutes, the following message will
appear:
Install disc found in drive — [960L V2.40R BUILD 1]
Update / Install 960L: press ’1’ to install
press ’0’ to continue with no install
Install complete. Please remove CD from drive.
2. Press 1 to begin installation. A number of progress messages will appear. When this
phase of installation is complete (after about one minute), the following message will
appear:

3. Remove the CD from the drive. Power down the system, wait a few seconds, then power
back up. The 960L will take a little longer to boot than normal.
If the LARC2 requires an update, the LARC2 will display the following menu:
4. Press 1 to begin the LARC2 update. This is the longest phase of the process, lasting about
10 minutes. The LARC2 will display a progress indicator. After the LARC2 update is
complete, the following message will appear:
Note:
When reinstalling Version 2.40, the unit will not ask to have the serial number re-
entered if this process was completed during a previous installation.
5. Enter the serial number as it appears on the back panel of the 960L mainframe. Do not
enter the first letter. Enter the numbers and the dash only. Press ENTER when finished. The
following message will appear:
Update needed on Larc2: Press ’1’ to update
Press ’0’ to ignore
Please enter serial number of the 960L from the back panel of
the 960L chassis. Do not use the serial number of the LARC2!
Enter numbers only. Do not enter first letter (shown as x )
Use minus for - : Use left arrow < for backspace : Finish
with ENTER.
x_
Please re-enter serial number for verification . . .

6. Enter the serial number again as it appears on the back panel of the 960L mainframe.
Once again, do not enter the first letter of the serial number. Enter the numbers and the
dash only. Press ENTER when finished and the system will start.
7. After the system has started, verify that the software has been installed properly. To do
this, press the CONTROL button, then the SYSTEM button, and read the version
information on the screen. The LARC2 version is 2.40 and the mainframe version is 2.40.
Once this process is complete, configure the system and continue working. It is
recommended to read the 960L Owner’s Manual to make the most of the 960L.

Installation Instructions & Release Notes Lexicon
REVERTING TO A PREVIOUS SOFTWARE VERSION
To revert to a previous version of 960L software, follow the same procedure outlined above
using the release CD for the desired software version. There is one special consideration:
When upgrading to Version 2.40, the software recognizes prior versions of user registers and
automatically converts them to a compatible format. The 960L software is not able to convert
back from later versions.
Therefore, when performing a "back-rev," erase all user registers before inserting the release
CD. It is recommended to save them first, noting the software version of the user registers.
Next, do a Factory Init.
To do this, follow the instructions below:
1. Power down the system, wait a few seconds, then power back up. As soon as the LARC2
receives power, go to Menu Mode by pressing and holding the PROGRAM and MACHINE
keys at the same time. Hold them until the following message appears:
Requesting menu mode from 960L . . .
7) Erase User Registers & Restore Factory Default Settings
Once the message appears, release the buttons. The 960L will take a little longer to boot
than normal. As soon as it is booted, a menu should appear on the LARC2. Ignore any
messages that concern locking the CD.
2. Select this item from the menu:
Once this process is complete, follow the installation instructions outlined on pages 4 and 5
using the release CD for the desired software version. A few messages will differ slightly.
When checking the software version (see Step 7 on page 5), please refer to the release notes
of the software version being installed to determine software revisions for the LARC2 and the
960L mainframe.

960L Version 2.40 Software
RELEASE NOTES
The list below includes features of the 960L Software Version 2.40 that are not fully covered
in the Owner’s Manual:
• When configuring systems with two DSP cards, there are no longer two soft buttons
labeled CONFIG 1 and CONFIG 2. In Version 2.40, there is one soft button labeled
"CONFIG v." When pressed, a menu will appear allowing selection of the DSP card for
configuration. In systems with one DSP card, there is no change.
• The ability to use double-button presses to access options has been removed in order to
support future functionality.
• Reverb algorithms now allow input levels to be set to a maximum level of 0dB. In
previous releases –6dB was the maximum.
Note:
Setting the input level above –6dB can result in DSP overflows.
• When processing audio, loading a very small Random Hall program while running a large
Random Hall program (i.e. loading Oil Drum while running Large Hall) may generate DSP
feedback. The level and duration of this feedback is dependent on the audio source. To
prevent feedback from occurring, mute the machine before loading the smaller Random
Hall program.
• Parameters with an OFF position in the center of the fader travel can now be set to OFF
by pressing and holding the FINE ADJ button and lightly touching the desired fader.
• Several banks of factory delay programs are visible, but not loadable, in the Version 2.40
software. To load these programs, upgrade to the 960L Version 2.50 software.
• Occasionally, LARC2 motorized faders may exhibit a "vibrating" characteristic when
settling into a new position as programs are loaded. This characteristic may appear to be
inconsistent from fader to fader. This is normal due to the varying characteristics of
individual fader components. The faders will settle into a stable position after a short
adjustment or calibration period.
