960L Version 2.4 Software

This document contains installation instructions for the 960L Version 2.4 Software. It describes

updated and enhanced features of Version 2.4, 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 2.4 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 5.)

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. The serial number consists of four digits, followed by a dash, followed

by four more digits. It is recommended to note this number before beginning

installation. (The unit will not ask to have the serial number re-entered if this process

was completed during a previous installation.)

• Refer to page 1-5 in the 960L Owner’s Manual for instructions to open the 960L front panel.

• Use the front panel standby button whenever the instructions call for the 960L to be

powered up or down. Do not use the back panel power switch.

• The installation process will take approximately 15 minutes.

1. While the 960L is powered up, insert the Version 2.4 CD. Using the front panel standby

button, power down the system, wait a few seconds, then power up the system again. After

a few minutes, the following message will appear:

These service instructions are for use by qualified personnel only. Do not perform

any servicing other than that contained in these instructions unless qualified to do

so. Refer to safety summary prior to performing any service.

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. Using the front panel standby button, power down the

system, wait a few seconds, then power up the system again. 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 2.4, the unit will not ask to have the serial number re-

entered if this process was completed during a previous installation.

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 2.4R and the mainframe version is 2.4R Build 1.

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.

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 2.4, 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. Using the front panel standby button, 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 3 to 5 using

the release CD for the desired software version. A few messages will differ slightly. When

checking the software version (see Step 7 above), please refer to the release notes of the software

version being installed to determine software revisions for the LARC2 and the 960L mainframe.

Installation Instructions & Release Notes Lexicon

RELEASE NOTES

The list below includes features of the 960L Software Version 2.4 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 2.4, 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 depends 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 2.4

software. To load these programs, upgrade to the 960L Version 2.5 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.

• Input/output routings need to be set after installing Version 2.4. 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.

Installation Instructions & Release Notes

960L Version 2.4 Software

• 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.
