The SSA can send its live analysis data to an LF Audio wireless display over AuralSync, so you can watch the analyzer from the driver's seat, a trunk panel, or your wrist while the SSA itself stays wherever it is installed. A wireless display is an optional accessory: the SSA works exactly the same on its own touchscreen with no display paired.
Which Displays Can Pair
| Display | What it shows from the SSA |
|---|---|
| WDD-LITE | The spectrum, oscilloscope, and waterfall views |
| AuralSync BassWatch | The spectrum, oscilloscope, and waterfall views |
| RTC | The spectrum, oscilloscope, and waterfall views |
A paired display shows the analysis views only. Volume and temperature views do not appear, because an analyzer has no volume control and no temperature probes. Because the SSA has four channels, the display also gets a channel selector so you can choose which pair of channels it draws.
If you have entered custom channel names on the Custom settings tab, the display picks them up and uses them to label the channels on its oscilloscope and waterfall views instead of generic numbers. Renaming a channel on the SSA updates the paired display without any action on the display.
The SSA never advertises itself for pairing on its own. It only becomes discoverable while you have deliberately put it into pairing mode, using one of the two methods below.
Putting the SSA into Pairing Mode
You can start pairing from the front-panel button or from the touchscreen. Both do the same thing.
From the front-panel button
- Press the front-panel button three times in a row.
- The front indicator light begins to flash. Flashing means pairing mode is live and the analyzer is discoverable. A steady light means it is not.
- The touchscreen shows a Pairing Mode message while it waits.
From the touchscreen
- Open Settings (gear icon), then the System tab.
- Under Display Pairing, press Pair Display and confirm.
- The button changes to Stop Pairing and the front indicator light begins to flash.
Then, on the display
Start pairing on the display itself and select the SSA from the list of LF Audio devices it finds. The SSA touchscreen shows a brief confirmation once the display is paired, and the indicator light returns to steady.
To leave pairing mode without pairing anything, press the front-panel button three times again, or press Stop Pairing on the System tab.
The analyzer is discoverable only while the light is flashing. If the light stops flashing before the display finds it, put the SSA back into pairing mode and try again.
Pairing More Than One Display
You can pair several displays to one SSA. Enter pairing mode again and pair the next display the same way.
Displays that are already paired keep receiving live data throughout the pairing window, and the analyzer does not restart when a new display joins, so adding a display never interrupts a session in progress.
Reviewing Paired Displays
Open Settings, then the Devices tab, for the Paired Displays list. Each paired display gets a row showing:
| Field | What it means |
|---|---|
| Device and address | The display type and the last part of its wireless address, so you can tell two of the same model apart |
| Firmware version | The firmware the display is running |
| Connection | Whether that display is connected right now |
| Signal | Link signal strength for that display |
| Link speed | High Speed or Long Range. Long Range trades throughput for distance and is used when a display cannot run at the faster rate |
| Forget | Removes this display from the analyzer |
If no display has ever been paired, the tab reads No displays paired and points you at Pair Display on the System tab.
Removing a Display
- Remove one display: open Settings > Devices, press Forget on that display's row, and confirm. You will need to pair it again to use it.
- Remove every display: press and hold the front-panel button for about two seconds. This clears all paired displays and restarts the analyzer.
Removing a display from the SSA clears the analyzer's side of the pairing. The display keeps its own stored pairing until you also clear it there (on LF Audio displays this is Advanced > Forget Base). Clear both sides when you want a completely fresh pairing.
Staying Connected
Once paired, a display reconnects to the analyzer on its own whenever both are powered on and in range. If the analyzer is switched off, the display shows a reconnecting status and returns to live data when the analyzer comes back.
Fixed in analyzer firmware 4.8.3: a paired display could occasionally lose its wireless link to the analyzer and stay stuck reconnecting, and the only way back was to clear the pairing on the display and pair again. That fault is fixed at the source, so the workaround is no longer needed. Displays left running on a live analysis view were the most exposed to it, because the problem scaled with how much data the display was requesting, so those sessions are the ones that improve the most. If you are seeing this behavior, update the analyzer to 4.8.3 or newer; see Installation and Wiring for how firmware updates work.
Secured links and older pairings
A display paired while the analyzer is running firmware 4.8.0 or newer uses a secured wireless link. A pairing created on older analyzer firmware stays unsecured until you pair that display again, which has two consequences worth knowing:
- Unsecured pairings were never affected by the reconnecting fault described above, so there is nothing to fix on them.
- Only a display on a secured link can start an analyzer firmware update from its own menu (Advanced > Update Base). If that option does nothing on an older pairing, remove the display and pair it again to move it onto a secured link.
Re-pairing is only ever needed for the reasons above. Updating the analyzer's firmware on its own does not require you to re-pair anything.
Troubleshooting
| Symptom | What to do |
|---|---|
| The display's scan does not list the SSA | The analyzer is only discoverable while its front light is flashing. Put it back into pairing mode and rescan on the display. |
| Pairing mode ends before the display finds it | Start the display's scan first, then put the SSA into pairing mode, so the two windows overlap. |
| Paired, but the display shows no data | Confirm the display appears as connected on Settings > Devices. If it does not, move the display closer and check the signal reading on that row. |
| Display stays on a reconnecting status | Confirm the analyzer is powered on. If it is, and the display never recovers, update the analyzer to firmware 4.8.3 or newer, which fixes a fault that could make this permanent. |
| Update Base on the display does nothing | That option needs a secured link and analyzer firmware 4.8.0 or newer. Update the analyzer, then remove and re-pair the display. The analyzer also needs WiFi credentials saved on its WiFi settings tab to download an update. |
| A display you no longer use still appears in the list | Press Forget on its row in Settings > Devices. |
