344 Appendix E: Updating The PRO1 Host Software
PRO1 Live Audio System
Operator Manual
Using the PRO1 updater
This section shows you how to update your PRO1 Live Audio System. However, before
you begin there are a few things you will need and some things you must do.
What you will need
Before you begin, check that you have the following:
• USB memory stick The USB memory stick (flash drive) must have enough
available memory to store any shows that you will need to backup, plus an additional
150MB of memory for the update package (that is, the file with a .tar extension). It
should also preferably be of USB 2.0 specification.
• Stable mains supply If the power drops at a critical point during the update, it is
possible — although unlikely — that this could cause some of the system
components not to function. A warning window opens before you start the update
procedure to remind you of this.
Preparation
Before you begin, we recommend that you do the following:
• Backup your shows It is likely that any shows will be erased when you power
cycle the PRO1 following an update. We therefore recommend that you backup your
shows onto the USB memory stick (see “Saving your show files to a USB memory
stick” on page 88), and then copy them onto a PC.
• Check that everything is connected Make sure that everything on the system is
correctly connected, configured and functioning properly.
• Switch off speakers During the update procedure the DSP and AES routing may
perform a number of resets during which the audio may not be in a controlled state.
We therefore recommend that you switch off any speakers connected to the system.
• Make sure you have enough time The update procedure may take quite a while
to complete, so make sure you have at least 25 minutes free before you start. We
do not recommend carrying out an update just before a performance!
• Configure the USB memory stick Create a folder at the top level (root directory)
of your USB memory stick called “DL1upgrades”. Then, copy the latest update file
(DL1xxx.tar) into it.
Updating your system
UPGRADING YOUR SYSTEM WILL CAUSE THE CONTROL CENTRE TO LOSE
SYNCHRONISATION, WHICH CAN RESULT IN LOUD NOISES FROM THE
SYSTEM. ALWAYS MUTE THE PA AT THE AMPLIFIER/SPEAKER BEFORE
UPDATING YOUR SYSTEM.
Do not switch off the power to any of the system devices while the PRO1 is
carrying out the installation of the host software.
The installation process is carried out with the PRO1 Control Centre fully powered up
and operational.
