The RTC (Rotary Touch Controller) is a wireless remote control and monitoring display for WVC-PRO and WVC-LITE multi-zone audio systems. It gives you full control over your system from anywhere in the vehicle: adjust volume, monitor system health, change settings, and update firmware, all from a compact circular touchscreen with a built-in rotary encoder.
Key Features
- Circular AMOLED touchscreen: vivid, high-contrast display viewable in any lighting condition
- Rotary encoder with push button: precise volume control and menu navigation without looking at the screen
- Dual-input control: use touch, the rotary encoder, or both interchangeably on any screen
- Wireless connection: communicates with your base station over a dedicated wireless link (no Bluetooth or phone required)
- Real-time monitoring: view voltage, temperature, and signal quality at a glance, with min/max readouts that can track historical extremes or the current graph window
- Live audio visualization (WVC Pro / WVC-PRO 6 only): FFT spectrum analyzer, oscilloscope, waterfall, and hi-res FFT views, with an option to show all channels combined or one channel per screen
- Per-channel CLIP indicators (WVC Pro / WVC-PRO 6 only, firmware 3.10.5+): yellow/orange/red CLIP pills appear on each channel of the audio visualizer views the moment that channel starts clipping
- Multi-zone volume control: independent volume adjustment for up to 4 channel groups on the main display (the underlying mesh supports more groups via the AuralSync app, but the RTC's volume ring caps the visualization at 4), with the active group's name shown above its volume reading
- Over-the-air firmware updates: update both the RTC and the base station wirelessly
- Adjustable brightness: 10-100% display brightness to match your environment
- Encrypted communication: always-on AuralSync mesh encryption for secure operation
- Automatic channel scanning: finds the best wireless channel for reliable communication
Compatibility
The RTC works with the following LF Audio base stations:
| Base Station | Supported | Notes |
|---|---|---|
| WVC-PRO | Yes | Full feature set including audio visualization, temperature monitoring, and all IDS modes |
| WVC-PRO 6 | Yes | Full feature set plus daughtercard firmware info |
| WVC | Yes | Core features: volume, voltage monitoring, IDS (Off/Mute/Limit Vol), settings |
| WVC-LITE | Yes | Core features: volume, voltage monitoring, IDS (Off/Mute/Limit Vol), settings |
| WVC-LITE 6 | Yes | Core features across 6 channels: volume, voltage monitoring, IDS (Off/Mute/Limit Vol), settings. No signal analysis or temperature views |

What's in the Box
- RTC (Rotary Touch Controller)
- 3-pin power cable (Ground / +12V / Remote Turn-On)
- Mounting hardware (gauge pod, flat-mount nut and set screw, 52mm gauge adapter)
Pairing
Pairing is a simple, non-destructive flow: put your base station in pairing mode (press its button three times, until the front light flashes), and the RTC finds it. Your base station keeps its existing settings and any other paired controllers, so the same steps work for a brand-new install and for adding an RTC to a system that already has a knob on it.
The RTC always shows a list of the LF Audio devices it finds, so you pick which one to connect to. Besides a base station, it can also pair with an SSA analyzer, a WTH temperature hub, or a High Precision Voltmeter as a source.
See First Boot and Pairing for the full wizard. Multiple RTCs and knobs can co-exist on the same base station, up to the base station's controller limit (typically two).
