The WDD-LITE (Wireless Data Display Lite) is a compact touchscreen display and controller for WVC-PRO, WVC-LITE, and WVC systems. It pairs with your WVC base station over a dedicated wireless link and shows live voltage, volume, temperature, and audio analysis on one bright AMOLED screen, while also letting you adjust the base station's settings from across the vehicle. It is a display and controller, not a standalone measuring device: everything it shows comes from the WVC base station it is paired to.
Navigation is entirely by touch. There is no rotary encoder and no buttons. You swipe, tap, and long-press to move between views and open menus.
Key Features
- 2.41" AMOLED touchscreen: a bright, high-contrast landscape display viewable at wide angles and in varied lighting
- Touch-only control: swipe between views, tap mode tabs, and long-press to open the menu, all with a bare finger
- Wireless connection: communicates with your WVC base station over the AuralSync wireless link (no Bluetooth or phone required for day-to-day use)
- Adaptive mode tab bar: a row of mode tabs along the bottom of the screen that adjusts automatically to what your base station supports (Volts and Volume always; Temperature, FFT, Oscilloscope, and Waterfall appear when the connected base supports them)
- Live monitoring: real-time voltage with a scrolling trend, per-channel-group volume faders, and amplifier temperature with min/max readouts
- Live audio visualization (WVC-PRO / WVC-PRO 6 only): FFT spectrum analyzer, oscilloscope, and a waterfall you can switch between a 3D mountain-range view and a 2D spectrogram (a scrolling spectrograph heatmap of frequency over time)
- Base station control: adjust IDS mode, competition mode, RCA gain, volume curve, voltage calibration, and more, sent straight to your WVC base station
- Over-the-air firmware updates: update both the WDD-LITE and the connected base station wirelessly
- Adjustable brightness: 10-100% display brightness to match your environment
- Customizable colors: 16 built-in themes plus per-element color overrides
- Encrypted communication: AuralSync mesh encryption is negotiated automatically during pairing
- Automatic channel scanning: finds the best wireless channel for a reliable connection
Compatibility
The WDD-LITE works with the following LF Audio base stations. The views and settings it offers adapt automatically to whichever base station it is paired with:
| Base Station | Supported | Available Views |
|---|---|---|
| WVC-PRO | Yes | Volts, Volume, Temperature (1 probe), FFT, Oscilloscope, Waterfall |
| WVC-PRO 6 | Yes | Volts, Volume, Temperature (3 probes), FFT, Oscilloscope, Waterfall |
| WVC | Yes | Volts, Volume |
| WVC-LITE | Yes | Volts, Volume |
| WVC-LITE 6 | Yes | Volts, Volume |
The WDD-LITE pairs with one base station at a time. See First Boot and Pairing for setup, and Display and Navigation for a tour of every view.
What the Mode Tabs Show
The bottom of the main screen carries a row of mode tabs. Which tabs appear depends on the connected base station's capabilities:
| Tab | Shows | Requires |
|---|---|---|
| VOLTS | System voltage as a large reading over a scrolling trend, with a min/max readout | Any WVC base station |
| VOLUME | Per-channel-group volume faders (or a single master fader) | Any WVC base station |
| TEMP | Amplifier temperature for each connected probe over a scrolling trend | A base station with temperature probes (WVC-PRO / WVC-PRO 6) |
| FFT | A real-time frequency spectrum of both channels | WVC-PRO / WVC-PRO 6 |
| SCOPE | A real-time oscilloscope waveform of both channels | WVC-PRO / WVC-PRO 6 |
| WFALL | A side-by-side waterfall of the audio spectrum over time, switchable between a 3D mountain-range and a 2D spectrogram (spectrograph) style | WVC-PRO / WVC-PRO 6 |
How It Differs From the RTC
The WDD-LITE and the RTC (Rotary Touch Controller) both display telemetry from and control a WVC base station, but they differ in form and input:
| WDD-LITE | RTC | |
|---|---|---|
| Screen | 2.41" rectangular AMOLED (landscape) | 1.5" circular AMOLED |
| Input | Touch only (swipe / tap / long-press) | Touch and a rotary encoder with push button |
| Volume control | View per-group volume faders | Turn the encoder to set volume directly |
| Mounting | Flat-panel display | Gauge pod / flat-mount / 52 mm adapter |
Because the WDD-LITE has no encoder, it focuses on displaying and configuring your system rather than turning a knob for volume. Direct touch volume control is planned for a future firmware update.
Specifications
| Display | 2.41" AMOLED capacitive touchscreen (landscape) |
