5. Topic Guide
5.1 Starting up, shutting down,
and firmware updates
We recommend switching the X32 on before any active sound reinforcement
system is connected. The function called “Safe Main Levels”, located in the
Setup/General Preferences screen, automatically turns down the main LRC bus
levels when booting the console, and also prevents any scene loading actions
from affecting (specifically turning up) the main levels.
Synchronization and Sample Rate settings can also be adjusted on the
Setup/Config page, but please note that changing the sample rate will require a
console reboot.
◊ Please Note: Settings under ‘Link Preferences’, ‘Panning Mode’,
and ‘DCA groups’ are stored with the Scene data while all other settings
made on the Setup/Config page are not stored in any preset and will
not be initialized either. Please verify before using the X32 that the
sample rate is set correctly and if the synchronization source is selected
appropriately. If set to external synchronization via one of the two
AES50 ports, while no clock source is actually connected or switched on,
then the corresponding small square icon in the main display’s top row
would be red rather than green. In normal state you should only see
1-4 green squares in the top section depending on the units connected.
Note that if the X32 console has previously been in use by somebody else, and you
feel unsure about its actual status, you can reset it to default settings in either of
two convenient ways:
1. While the console is booting up and the “X32” logo appears on the screen,
press and hold the “Scenes / UNDO” button, keeping it depressed until the
console is fully operational and the Home screen is displayed. The console
will now be in the exact same state as it was when first shipped from the
factory. However, you can immediately revert back to the status the console
was in before being switched off by pressing the Scenes/UNDO button.
2. You can also reset the console any time after booting by pressing
“Setup/Config” -> “Initialize”.
The X32 regularly stores the console’s status to its onboard flash memory,
so there is usually nothing wrong with switching it off, and you do not have to
explicitly save the current status. However, when a large number of parameters
have been recently changed, storing all of them to flash can take up to 1 minute,
in a “worst-case” scenario. In order to prevent any errors by losing power during
this type of storage operation, we recommend using the “Safe Shutdown”
function from the Setup/Global page, an operation similar to un-mounting a
USB thumb-drive from your PC.
Updates:
The X32 firmware can easily be updated by plugging a USB stick into the top
panel USB connector after a firmware update file has been downloaded and
stored on the root level of the attached drive. Simply insert the USB drive while
the console is turned off, then power on the console. While booting, the X32 will
run a fully automatic firmware update, which might take 2-3 minutes longer than
the regular boot sequence.
The USB socket is not suitable for other non-memory USB devices like keyboards,
mice, lamps, etc.
5.2 Default setup for connecting to monitoring
and P.A. systems
The X32 comes pre-configured with the local XLR inputs connected to input
channels 1-32, and XLR outputs 1-14 connected to the mix bus masters 1-14.
Bus masters 13-16 are connected to the effects inputs FX1-4. The Main LR (stereo)
signal is normally put out on XLR outputs 15/16.
The Monitoring outputs on ¼" and XLR connectors, and the two Phones outputs
(in the side-cap handles) always carry either the Monitor Source signal or any solo
signal, whenever a solo button is active. Press the View button in the Monitor
section to check or change the solo and monitoring preferences.
1. Power up the X32 console first, before any connected power amps or
speakers are switched on.
2. Connect cables to XLR outputs 15 and 16 on the rear panel, connecting the
other ends of the cables to the inputs of your P.A. system. These normally
carry the main stereo bus left and right.
3. All buses or input channels that are to be put out on the main PA system
must have their Stereo Bus switches on. Use the selected channel’s pan
control to place the signal within the main stereo field, and the channel’s
fader to set the volume.
4. Use the rear panel Monitoring outputs to connect monitor speakers or, if you
prefer, use the ¼" outputs in the sidecaps to connect your head phones.
You will either hear the monitor source signal, which is Main Stereo by
default, or any channel with its solo button being active.
5.3 How do I connect a microphone, process its
signal and send it out to the P.A. system?
1. Press the Select button of a desired input channel (for example, channel 1 on
the “Channels 1-16” input layer) and make sure the channel fader is down.
2. In the channel processing section in the upper left hand corner, make sure
the phantom power is switched off.
3. Connect a microphone to XLR input 1 on the X32’s rear panel.
4. Press the 48V button to switch phantom power on for channel 1
(if the microphone requires it, such as a condenser microphone).
5. Use the Gain control to adjust the gain level as necessary, using the input
meter as a guide.
6. Switch on and adjust the Low Cut filter as needed to remove rumble or
wind noise.
7. Adjust the channel equalizer controls to sculpt the sound quality of the
microphone signal.
8. Adjust the channel Gate and Compressor controls as desired. Note that by
pressing the “view” button in the compressor or gate section, the main
screen will switch to the compressor or gate display for the selected channel,
offering additional compressor or gate controls beyond the dedicated
top-panel controls.
9. Turn on the “Stereo Bus” switch in order to route the selected signal to
the main LR, then adjust the Pan control to place the signal within the
stereo field.
10. Adjust the Channel 1 fader to the 0 dB region, then slowly turn up the main
LR fader until you hear the mic signal amplified through your P.A. system.
