Preset Questions
How many presets are in the Vortex?
There are 16 factory presets and 32 user presets for a total of 48 presets. The presets store all the information in the
device including input gains, matrix cross points. Also, each device stores a complete set of text labels of inputs,
outputs, macros, presets, and logic pins.
How do the factory presets work? How are they set up?
The factory presets are stored in an area within the Vortex where they cannot be overwritten by a user. They are
provided to make it easy to get started using the Vortex. The factory presets are common setups that may be sufficient
for many different applications. The factory presets can be used as the basis for user presets, and then modified and
saved.
Does the Vortex come up as a "blank slate"?
The Vortex as shipped from the factory comes up in the default configuration of preset 0 and the power on preset is set
to 0. The Vortex can be configured to power up with any of the factory or user presets and will not come up blank unless
you save a blank preset and have it power up to that preset.
How do I select which preset the device powers up into?
On the presets page within Conference Composer you can select which preset to use when powering up. This can also
be set from the LCD and with RS-232 commands. The default from the factory is to power up into factory preset 0.
What if I make changes? Will the preset still be there?
Presets are stored in non-volatile memory. Once loaded into the Vortex, changes can be made to the settings of the
Vortex. However, unless the changes are saved as a preset (either a new preset or overwriting the existing preset), the
old preset values will be used the next time the device is powered up or reset. The changes are not saved to the non-
volatile memory unless you tell the settings to be saved.
Can I password protect presets?
Yes. There is an optional write-protect password (in addition to the front panel lock out password) that can be used to
prevent users from overwriting presets within the Vortex. When the Vortex is write-protected, the user can change
which preset is running in the device, but cannot save a new preset and cannot change the preset selected upon power-
up.
Software Questions
What type of computer do I need?
The minimum computer configuration for running Conference Composer is a 500 MHz Pentium computer with 128MB of
memory and 50MB of free disk space. The recommended system is a 700MHz or better Pentium with 256MB of memory
and 50MB of available disk space. Windows 2000 or Windows XP is recommended.
Can I work offline?
Yes. With Conference Composer you can work offline, design the system, and save files to disk. You can easily restore
files and upload information into a product when you decide to go online.
What do I need do do to set up my Vortex unit for operation?
In many cases, you don't need to do anything – a Vortex preset will work fine for your application. If you are dealing with
multiple microphones, different types of microphones, multiple loudspeakers and other equipment, we recommend that
you use the InstantDesigner software wizard. When you first open Conference Composer, you will be given the choice to
