Menus and Settings

The RTC provides a hierarchical menu system for accessing device settings, base station configuration, system information, and advanced functions. Open the menu with a long-press on the touchscreen or encoder button from any screen.

Menu Navigation

You can navigate the menu using either the touchscreen or the rotary encoder:

• Swipe up/down or rotate the encoder to move between menu items
• Tap or press the encoder button to activate the selected item
• The menu wraps around: scrolling past the last item returns to the first
• When you return from a sub-screen, the menu remembers your previous position

Each menu item displays an icon for easier identification. "Advanced" displays with a ">" indicator to show it opens a sub-menu. "Factory Reset" requires a confirmation step: selecting it opens a confirmation screen where you must choose "Confirm Reset" to proceed.

Navigating Settings Screens

All settings screens (Settings, Base Info, Base Settings, and System Info) share the same consistent layout and navigation:

• The screen title stays fixed at the top with a separator line below it. Tap the title to go back.
• Swipe up/down, drag vertically, or rotate the encoder to move between items. All items are selectable, including read-only information fields.
• Swipe right from any settings screen to go back to the menu.
• Tap or press the encoder button to activate the focused item. This toggles a switch, enters edit mode on a slider, cycles an option, or navigates to a sub-screen.
• A scroll indicator arc on the right edge shows your position in long lists.
• Editable items display a chevron indicator (›) to distinguish them from read-only fields.
• When editing a slider value, rotate the encoder to adjust, then press the encoder button to confirm.

Settings

Device-level settings for the RTC itself.

Setting	Type	Options / Range	Description
Brightness	Slider	10-100%	Display brightness level
Volume Units	Toggle	dB / %	How volume is displayed on the main screen
Volume Mode	Option	Normal / Vibration Guard / Locked	Controls how the encoder changes volume. Normal (default): turning the encoder changes volume as usual. Vibration Guard: requires a deliberate run of turns in the same direction before volume starts changing, so heavy bass or vibration in a loud install cannot change the volume on its own. Once you are deliberately turning, the encoder tracks normally; if you stop for about three-quarters of a second it re-arms so a fresh deliberate turn is needed to start changing again. The first step after it engages is gentle, then it speeds up if you keep turning, so the volume never jumps. Locked: the encoder does not change volume at all until you switch back to Normal or Vibration Guard.
Temp Units	Toggle	°F / °C	Temperature display units (only visible when connected to a PRO base station)
Channel View	Toggle	Combined / Single	How the Equalizer and Oscilloscope display channels. Combined (default) shows all channels in one screen. Single gives each channel its own Equalizer and Oscilloscope screen and you tap the canvas to advance to the next channel. See Display and Navigation for details.
Min/Max	Toggle	All-Time / Window	Controls the Min/Max readouts on the Voltage and Temperature graph screens. All-Time shows the lowest and highest values observed since the RTC was powered on. Window shows the lowest and highest values currently visible in the graph's rolling window.
Auto Swap	Toggle	On / Off	Automatically cycles between display views (PRO only)
Swap Time	Slider	1-60s	How long each view is shown before switching (child of Auto Swap)
O-Scope	Toggle	Show / Hide	Include Oscilloscope in the auto-swap cycle (child of Auto Swap)
Equalizer	Toggle	Show / Hide	Include Equalizer in the auto-swap cycle (child of Auto Swap)
Temperature	Toggle	Show / Hide	Include Temperature graph in the auto-swap cycle (child of Auto Swap)
WiFi	Navigation	(sub-menu)	Opens the WiFi settings screen for managing saved OTA update networks
Colors	Navigation	(sub-menu)	Opens the Colors menu: pick a built-in theme, design your own gradient, or override individual element colors

Colors

Customize the colors used on the main display, the audio visualizers, and the system 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. Tap Start or End to open the color picker.
Presets	A list of 16 ready-made themes. LF Audio is the default. Tap one to apply it instantly: the preset defines every color and any previous Advanced Color overrides are cleared. The active theme has a bright white border around its swatch.
Advanced Colors	Override any single element's color individually. A single Left Channel / Right Channel pair drives the channel colors across every Channel view (Equalizer, Oscilloscope, Waterfall, and Hi-Res Equalizer), so changing them updates all four views at once. The list only shows rows that apply to your setup: Left Channel, Right Channel, and Temp rows are hidden when your base station doesn't support those views, and Group 2 / 3 / 4 rows are hidden when your unit has fewer groups. If you've renamed your voltage or temperature probes from the LF Audio AuralSync app (firmware 3.10.0+), your custom names appear here in place of Voltage / Temp 1 / Temp 2 / Temp 3, so you can pick the color for the named probe directly. Overridden items show a bright white border around the swatch.
Reset All Colors	Restores the default LF Audio palette and clears every individual override. Asks for confirmation.

Available presets

All 16 presets ship on every RTC. They define both the main theme gradient and every per-element color in one tap:

Preset	Style
LF Audio	The default LF Audio brand palette
Sunset	Hot pink to gold
Ocean	Cyan to deep blue
Inferno	Gold to deep red
Mono Pink	Soft single-hue pink
Forest	Green to teal
Neon	High-saturation neon brights
Plasma	Purple to magenta
Lava	Orange to dark red
Ice	Cool white to pale blue
Apex	Lime to racing green
Bass	Hot pink to deep purple
Crimson	Rich red palette
Royal	Sky blue to deep royal indigo
Mint	Soft green to mint
Vapor	Vaporwave pinks and cyans

Using the color picker

The picker shows a 2D color wheel with a value slider beneath it.

• Touch the wheel to pick the color directly. Angle sets the hue, distance from the center sets how vivid it is.
• Drag the slider at the bottom to adjust brightness.
• Rotate the encoder to scroll the hue around the wheel.
• Tap the screen (anywhere outside the wheel/slider) or press the encoder to save the color.
• Swipe right or long-press to cancel without saving.

While you adjust, the main display previews the change live behind the picker.

Base Info

Read-only information about the connected base station. Values update automatically while this screen is open.

Field	Description
Model	Base station model (e.g., WVC-PRO, WVC-PRO 6, WVC-LITE)
Hardware	Base station hardware version
Daughtercard HW	Daughtercard hardware version (WVC-PRO 6 only)
CPU1 FW	Main processor firmware version

CPU3 FW	Daughtercard firmware version (WVC-PRO 6 only)
Built	Base station manufacture date
Uptime	Time since the base station was last powered on
Name	Bluetooth device name of the base station
UUID	Unique device identifier
BT Pin	Bluetooth pairing PIN
Home Mode	Home Mode WiFi state: "Off", "Connecting…", "Connected", "Reconnecting…", or "Failed" (only shown when connected to base station firmware 3.9.0 or newer)
Home Name	Name of the smart home this base station is commissioned to via Matter (only shown when commissioned)

Base Settings

Configuration options for the connected base station. Changes are sent to the base station immediately when you adjust a value. 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 conditions. For full details on what each mode does (including recovery behavior), see the Intelligent Drive System (IDS) article.

WVC-PRO options:

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 is restored 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 by about 2% per second 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

When IDS Mode is set to anything other than Off, these child settings appear:

• Min Voltage (slider, 6.0V-18.0V, step 0.1V): the voltage threshold below which IDS triggers. Most 12V car audio systems operate between 12.0V-14.4V; a typical safe threshold is 11.0V-11.5V. The on-device WVC-PRO 6 UI and the AuralSync app extend this slider to 22.0V.
• Max Temp: the temperature threshold above which IDS triggers (PRO only). The slider range and units match your selected Temp Units: 80-240 °F in 5 °F steps when Fahrenheit is selected, or 27-116 °C in 3 °C steps when Celsius is selected. A typical safe threshold for car amplifiers is around 150-160 °F (65-70 °C).

Competition Mode

Controls audio behavior during competition (e.g., SPL contests).

Option	Behavior
Off	Normal operation
Mute	Mutes all audio output
Limit Volume	Limits 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 turned on:

• Max Startup Vol (slider, 0-100%, step 1%): caps the volume level at startup to prevent the system from powering on at full volume. Only available on base station firmware 3.5.0 or newer.

RCA Gain

Toggles RCA output gain on or off. When on, a Gain Level slider (or per-channel rows on multi-unit mesh systems) lets you boost the signal from 0 dB to +31.5 dB in 0.5 dB steps. The first time you enable it in a session, the RTC shows a confirmation screen that you must explicitly accept.

On a multi-unit mesh system, the single Gain Level slider is replaced by per-channel gain rows. Each row is labeled with the unit (Unit 1, Unit 2 ...) and the channel within that unit (Chan 1 gain ... Chan 6 gain). The current calculated output voltage for that channel is shown in a small preview next to the row (for example, 1.78v out), so you can dial each channel to a target voltage individually. If you've renamed channels from the LF Audio AuralSync app (firmware 3.10.0+), the per-channel rows use your custom names so you know exactly which channel you are adjusting.

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 boost curves at different source voltages, the safe enable procedure (DMM measurement, power-down ordering, etc.), and the liability disclaimer, see RCA Gain. Do not enable this feature without reading that article.

Volume Curve

Selects the volume curve profile that determines how the volume knob position maps to output level. A live visualization of the selected curve is shown below the selector.

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 volume range is concentrated in the upper portion of the knob
S-Curve	Smooth start and finish: gradual changes at both ends, moderate changes in the middle
Competition	Very steep: minimal volume until near the top of the range, then rapid increase

Voltage Drift

A calibration offset applied to the voltage reading (range: -5.0V to +5.0V, step 0.01V). Use this if the displayed voltage does not match a known-accurate voltmeter reading.

Live Voltage (read-only)

At the bottom of Base Settings, a live Voltage row shows the current vehicle voltage as the base station is reading it right now, updating about every 2 seconds. This is the same number you would see on the Voltage view, surfaced here so you can verify the Voltage Drift calibration result without leaving the settings screen.

Advanced Menu

The Advanced sub-menu contains firmware update tools, mesh configuration, and factory reset. Select "Advanced" from the main menu to enter this sub-menu, and select "Back" to return.

FW Update

Starts an over-the-air firmware update for the RTC itself. When connected to a base station, the update uses the base station's WiFi credentials. When not connected, the RTC tries cached base WiFi, then saved custom networks, then opens a WiFi discovery wizard if needed. See Firmware Updates for the full workflow.

Update Base

Sends a firmware update request to the connected base station. The base station will then download and install its own update. Only available when connected. See Firmware Updates for details.

Pair WVC

Opens a step-by-step wizard for adding a secondary WVC base station to your mesh network. Use this when you have multiple WVC amplifiers and want them all to respond to the same RTC. The wizard walks you through putting the secondary WVC into pairing mode and linking it to the primary base station.

Channel Groups

Opens a configuration screen where you can assign individual amplifier channels to volume groups. Channel groups let you control multiple channels together as a single zone. For example, group front and rear speakers so they share one volume level, while a subwoofer channel has its own independent volume.

Each group can also be renamed in this screen. Select a group, then choose the rename option to open the on-device keyboard: rotate the encoder or swipe through the character wheel to enter each character, press the encoder or tap to confirm, and select Done when finished. Group names appear above each zone's volume reading on the main screen and on the per-channel gain rows under RCA Gain.

Pair Knob

Opens a wizard for adding another RTC or knob controller to the mesh network. Use this when you want multiple controllers (for example, one in the driver's area and one in the passenger area) that can both control the same system.

Smart Home

Opens the Smart Home screen, showing the base station's Home Mode WiFi connection state and Matter smart home pairing state. From this screen you can:

• Turn Home Mode on or off: Home Mode connects your base station to your home WiFi network so it can be controlled by smart home apps.
• Retry the WiFi connection if it failed.
• Decommission the base station from your smart home: removes it from Google Home, Amazon Alexa, or Apple Home.
• Re-pair: when the base station is in a Matter state that allows re-commissioning, this action decommissions the current pairing and starts fresh so you can add the base station back. Re-pair is only offered when the on-device Smart Home screen detects that state, not on every Matter state.

Each action opens a confirmation screen first. Destructive actions (Disable, Decommission, Re-pair) default to Cancel so you have to explicitly confirm. After confirming, a waiting spinner is shown while the base station applies the change.

When Home Mode WiFi fails to connect, an Issue row appears at the top of the Smart Home screen with a short reason: Set WiFi in app, Network not found, Wrong password, Connection timed out, or Unknown. Use this to decide whether to retry from the RTC or fix the WiFi credentials in the LF Audio AuralSync app first.

When the base station is awaiting Matter commissioning, a Pairing Code row appears showing the 11-digit Matter pairing code. Enter this code in your smart-home app (Google Home, Amazon Alexa, or Apple Home) when it prompts you for a numeric pairing code. The code is regenerated each time you start the commissioning flow.

WiFi Settings (sub-screen)

The WiFi entry in the Settings menu opens a sub-screen for managing the networks the RTC uses for over-the-air updates:

• A list of your saved custom networks, with the most recent at the top. Each entry shows the SSID; select one and choose Forget to remove it.
• An Add Network entry that opens the same character-wheel keyboard used by the WiFi discovery wizard, so you can pre-populate a network without going through the update flow.
• The Cached Base Station WiFi entry, which can be cleared if you change the base station's WiFi network.

See Firmware Updates for how each of these networks is used during an update.

Factory Reset

Clears all saved settings and pairing information, then restarts the RTC. After a factory reset, the RTC will show the Getting Started Wizard to pair with a base station as if it were brand new.

Selecting Factory Reset opens a confirmation screen. You must choose "Confirm Reset" to proceed; this prevents accidental resets.
