960L Version 2.5 Software
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 2.5 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.
This document contains installation instructions for the 960L Version 2.5 Software. It describes
updated and enhanced features of Version 2.5, and discusses items that did not receive full
coverage in the 960L Owner’s Manual. Refer to the owner’s manual, particularly the Version 2.5
addendum, for additional information about the new software.

7) Erase User Registers & Restore Factory Default Settings
REVERTING TO A PREVIOUS SOFTWARE VERSION
To revert to a previous version of 960L software, follow the same procedure outlined on pages 3
to 5 using the release CD for the desired software version. There is one special consideration:
When upgrading to Version 2.5, 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.
1. Using the front panel standby button, power down the 960L, wait a few seconds, then power
up the system again. 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:
Once this 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:
Requesting menu mode from 960L . . .
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), refer to the release notes for the software
version being installed to determine software revisions for the LARC2 and the 960L mainframe.
RELEASE NOTES
• When configuring systems with two DSP cards, there are no longer two soft buttons labeled
CONFIG 1 and CONFIG 2. In Version 2.5, there is one soft button labeled CONFIG v. When
pressed, a menu will appear allowing selection of the desired 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 some
previous releases, –6dB was the maximum.

Installation Instructions & Release Notes
960L Version 2.5 Software
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 the feedback depends on the audio source. To prevent
feedback from occurring, mute the machine before loading the smaller Random Hall
program.
• Occasionally, LARC2 motorized faders may exhibit a "vibrating" characteristic when settling
into a new position as programs are loaded. The 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.
• Input/output routings need to be set after installing Version 2.5. Once set, the input/output
routings are saved with the configuration and will be automatically recalled when that DSP
configuration is loaded.
• Input/output routings saved with each configuration may become invalid if the order of the
input/output cards is changed or if an input/output card is removed from the unit. If this
occurs, simply reset the input/output routings.
• Manual fader adjustment may be prevented when the fader is automatically positioned near
the top or bottom of its physical range, even if the parameter is not set to its maximum or
minimum value. To overcome this anomaly, move the fader in the opposite direction, then to
the desired value.
• The LtRt outputs of the five-output configurations cannot be routed as inputs to the second
optional reverb DSP card.
• The two machine outputs in the five-channel cascades are mixed to allow processed material
from the first machine to simultaneously pass directly to the system output and feed the
second machine. Phasing and comb filtering will occur if dry signal is passed through both
machines.
