Base Info and Base Settings only appear when the WDD-LITE is connected to a base station, since they describe and configure the connected base.
Settings
Device-level settings for the WDD-LITE itself. Changes are saved automatically.
| Setting | Type | Options / Range | Description |
|---|---|---|---|
| Brightness | Slider | 10-100% | Display brightness level. Applies immediately as you adjust it. |
| Orientation | Navigation | (sub-menu) | Set the display orientation: Landscape, Landscape Flipped, Portrait, or Portrait Flipped. The display restarts to apply your choice. Default is Landscape. |
| Volume Units | Toggle | dB / % | How volume is shown on the Volume console and the top-bar glance |
| Temp Units | Toggle | °F / °C | Temperature display units. Only visible when connected to a base station that supports temperature probes (WVC-PRO / WVC-PRO 6). |
| Min/Max | Toggle | All-Time / Window | Controls the min/max readout under the Volts view. All-Time shows the lowest and highest values since power-on; Window shows the lowest and highest values currently visible in the trend graph. |
| Auto Swap | Toggle | On / Off | Automatically cycles the main display through the available mode tabs |
| Swap Time | Slider | 2-60s | How long each mode is shown before switching (appears only when Auto Swap is on) |
| Sleep | Toggle | On / Off | Battery-equipped units only. Puts the screen to sleep after a period without touch, to conserve the battery. Sleep applies only while the display is running on its battery: with external power connected the screen stays on. Default On. |
| Sleep After | Enum | 1, 2, 5, 10, 15, 20, 30, 45, 60, 90, or 120 min | How long the display sits untouched before the screen sleeps (appears only when Sleep is on). Default 20 minutes. |
| Colors | Navigation | (sub-menu) | Opens the Colors menu: pick a built-in theme, edit the gradient, or override individual element colors |
| WiFi | Navigation | (sub-menu) | Manage the WiFi networks used for firmware updates. See Firmware Updates |
Orientation
Set which way the display renders in Settings > Orientation. Four options are available: Landscape (the default), Landscape Flipped, Portrait, and Portrait Flipped. Pick the one that matches how the unit is mounted, then confirm; the WDD-LITE restarts to apply it. Your choice is kept when you use Forget Base, and is reset to Landscape by a Factory Reset.
Sleep (Battery-Equipped Units)
On a WDD-LITE fitted with the optional battery, the screen sleeps after the period set in Settings > Sleep After to conserve charge. Tap the screen to wake it; the display comes back to the same view you left it on. Plugging the display in also wakes it.
Sleep is suspended whenever the display is on external power, so a hard-wired or USB-C-powered unit never sleeps. Turn the Sleep toggle off to keep the screen on even when running from the battery.
The Sleep and Sleep After rows appear only on a battery-equipped unit; a standard WDD-LITE never shows them.
Colors
Customize the colors used across the display, audio visualizers, and status icons. Your choices are saved automatically and survive reboots and firmware updates.
| Item | Description |
|---|---|
| Theme Gradient | Edit the two-color gradient that drives the volume groups, channel views, voltage, and temperature probes. The currently active theme's name is shown here. |
| Presets | A list of 16 ready-made themes. LF Audio is the default. Tap one to apply it instantly. The active theme has a bright border around its swatch. |
| Advanced Colors | Override individual element colors one at a time. Every color slot the display uses is listed; an overridden slot is marked with a bright border on its swatch. |
| Reset All Colors | Restores the default LF Audio palette and clears every individual override, after a confirmation step |
Available Presets
All 16 presets ship on every WDD-LITE:
LF Audio (default), Sunset, Ocean, Inferno, Mono Pink, Forest, Neon, Plasma, Lava, Ice, Apex, Bass, Crimson, Royal, Mint, and Vapor.
Using the Color Picker
When you choose a color, a picker appears with a color wheel and a brightness slider:
- Touch the wheel to set the color. The angle sets the hue, and the distance from the center sets how vivid it is.
- Drag the slider to adjust brightness.
- Tap OK to save, or Cancel (or swipe right) to discard.
Base Info

Base Settings
Configuration options for the connected base station. Changes are sent to the base station immediately. Some settings have child options that appear or hide based on the parent value.
IDS Mode (Intelligent Drive System)
Controls how the system responds to abnormal voltage or temperature. For full details on what each mode does, see the Intelligent Drive System (IDS) article.
| Option | Behavior |
|---|---|
| Off | IDS disabled |
| Mute | Sets volume to 0 when triggered. Volume stays at 0 after the condition clears, so turn it back up manually. |
| Rem Off | Drops the Remote Out signal when triggered, turning off any amplifier wired through it. Remote Out restores automatically about 1 second after the condition clears. |
| Mute+Rem | Both sets volume to 0 and drops Remote Out. Remote Out auto-restores; volume must be turned back up manually. |
| Limit Vol | Gradually reduces volume while triggered. Volume stays at the reduced level after the condition clears, so turn it back up manually. |
WVC-LITE options: Off, Mute, Limit Vol (a LITE base has no remote-output wire, so the Rem Off modes do not apply). The WDD-LITE automatically offers only the modes your base station supports.
When IDS Mode is set to anything other than Off, these child settings appear:
- Min Voltage (slider, 6.0-18.0V, step 0.1V): the voltage threshold below which IDS triggers. Most 12 V car audio systems run between 12.0V-14.4V; a typical safe threshold is 11.0V-11.5V.
- Max Temp (WVC-PRO / WVC-PRO 6 only): the temperature threshold above which IDS triggers. The slider range matches your selected Temp Units: 80-240 °F or 27-116 °C. A typical safe threshold for car amplifiers is around 150-160 °F (65-70 °C). This appears only when the connected base station supports temperature probes.
Competition Mode
Controls audio behavior during competition (for example, SPL contests).
| Option | Behavior |
|---|---|
| Off | Normal operation |
| Mute | Mutes all audio output |
| Limit Vol | Limits the maximum volume level |
Remember Vol
When enabled, the base station saves the current volume level and restores it after a power cycle. When this is on:
- Max Startup Vol (slider, 0-100%, step 1%): caps the volume at startup so the system never powers on at full volume. Available on base station firmware 3.5.0 or newer.
RCA Gain
Toggles RCA output gain on or off. The first time you enable it, the WDD-LITE shows a full-screen overvoltage warning that you must accept before gain is applied. On older base stations a Gain Level slider also appears, letting you boost the signal from 0 dB to +31.5 dB in 0.5 dB steps, with a live output-voltage preview.
Important: Gain can drive the RCA outputs to voltages that exceed the rated input of most car amplifiers and can permanently damage equipment if set incorrectly. For the full safety warning, the gain calculator, the safe enable procedure (measuring with a multimeter, power-down ordering, and so on), and the liability disclaimer, see RCA Gain. Do not enable this feature without reading that article.
Volume Curve
Selects the curve that maps the volume knob position to output level. A live graph and a short description of the selected curve are shown.
| Curve | Behavior |
|---|---|
| Natural | Logarithmic response. Most volume change at the low end, feels natural to the ear |
| Linear | Even response: equal volume change per step across the full range |
| Audio Taper | Steep response. Most of the range is concentrated in the upper portion of the knob |
| S-Curve | Smooth at both ends, moderate change in the middle |
| Competition | Very steep: minimal volume until near the top, then a rapid increase |
Volume Curve is only available when connected to base station firmware 3.2.0 or newer.
Volume Floor
Sets the quietest level the system will output at any volume setting above zero, so the lowest usable volume stays controllable instead of dropping to near-silence. Turn Volume Floor on to enable it; when it is on, a Floor Level control appears so you can set how low it goes. The floor is stored on the base station and applies on top of whichever Volume Curve you have selected.
Volume Floor is only available when connected to base station firmware 4.4.0 or newer.
Voltage Drift
A calibration offset applied to the voltage reading (range -5.0V to +5.0V, step 0.05V). Use this if the displayed voltage does not match a known-accurate voltmeter.
Live Voltage
At the bottom of Base Settings, a live Voltage row shows the current vehicle voltage as the base station reads it, updating about every half second. This lets you verify a Voltage Drift adjustment without leaving the screen.
Advanced
The Advanced screen holds firmware updates and the reset actions. Each destructive action requires an inline confirmation.
Update Firmware
Starts an over-the-air firmware update for the WDD-LITE itself. It only installs a version newer than the one already on the device. See Firmware Updates for the full workflow.
Repair Firmware
Installs the latest published firmware even when the WDD-LITE is already up to date (a normal Update Firmware stops and reports "up to date" in that case). It uses the same WiFi and download steps as Update Firmware. Use it to repair an update that was interrupted, or firmware that is misbehaving, or when LF Audio support asks you to. See Firmware Updates.
Update Base
Sends an update request to the connected base station, which then downloads and installs its own update. See Firmware Updates.
If your system is a mesh with more than one base station, this row reads Update All Bases: a single selection updates every base station in the mesh, not just the one the WDD-LITE is connected to.
This option appears only when you are connected to a WVC base station. It does not appear when you are connected to a Smart Signal Analyzer or a Temperature Hub, which are updated from their own screens rather than from the WDD-LITE.
Forget Base
Clears the stored pairing and restarts the WDD-LITE, bringing back the getting-started wizard so you can pair a different base station. Your display preferences, color theme, and saved WiFi networks are kept. You must choose Confirm Forget to proceed.
Factory Reset
Clears all stored settings, display preferences, color theme, and pairing, then restarts the WDD-LITE into the getting-started wizard. You must choose Confirm Reset to proceed.
Factory Reset erases your pairing, display preferences (units, min/max, auto-swap, orientation), color theme, and the saved WiFi networks used for firmware updates, then restarts the WDD-LITE. You will need to re-pair with your base station afterward and re-enter a WiFi network the next time you update. Use Forget Base instead if you only want to re-pair without losing your other settings (Forget Base keeps your preferences, theme, and saved WiFi networks).
Battery
Battery-equipped units only. This screen shows the current charge level as a large reading with the battery voltage beneath it, over a trend graph of the battery voltage so you can see how it has been discharging. While the display is plugged in it shows Charging in place of the charge percentage, because the charger holds the battery voltage up and a percentage read at that moment would be optimistic. A Back item returns you to the menu.
On these units the top bar also carries a battery icon with the charge level next to the signal-strength meter, which changes to a charging symbol while the display is plugged in. A standard WDD-LITE has neither the Battery menu item nor the top-bar battery indicator.
