Tap the gear icon on any device's monitoring screen to open its settings. The settings screen uses tabs across the top. The exact tabs you see depend on your device model and whether you are signed in:
| Tab | Always shown? | Notes |
|---|---|---|
| INFO | Yes | Read-only device facts. |
| APP | Most devices | Per-device app-side display preferences (varies by model). |
| DEVICE | Most devices | Settings stored on the device itself. Subtabs depend on model + firmware. |
| SESSIONS | Only when signed in | Per-device recording history. See Recording Sessions. |
INFO Tab
Displays read-only information about your connected device:
| Field | Description |
|---|---|
| Device Name | Current device name. To change it, open the DEVICE tab. On a WVC or HPVM, its first tab shows Device Name. |
| Model | Hardware model (for example, WVC-PRO, HPVM-24). |
| Hardware Version | Circuit board revision. |
| Firmware | Current firmware version(s). For multi-processor devices like WVC, both CPU1 and CPU2 are shown; on WVC-PRO-6 the daughtercard firmware is also shown. |
| Manufactured | Date the device was manufactured. |
| UUID | Unique identifier for the device. Tap the row to copy it to your clipboard. |
| Status | Mesh-pairing state (Normal, Pairing Mode, Awaiting First Knob). WVC family only. |
Some fields only appear for specific device models. For example, CPU2 firmware only shows on devices with a secondary processor (the WVC family).
To rename a WVC base station, use the app. Open the DEVICE tab. Its first tab shows Device Name. Edit the name there. A name can be up to 15 characters. You can also rename it from a knob or display, in Base Info > Name. The base station needs CPU1 4.12.2 or newer and CPU2 4.13.1 or newer. Update your knob or display to its latest firmware too. A knob or display renames the base station shown in its Base Info. To rename any other base station, use the app. See Firmware Updates.
APP Tab
Controls how the app displays data for this device. Most settings here are stored on your phone.
The available controls depend on your device model. Examples:
- WVC family: a single Use Graph for Volume toggle that switches the volume readout between a numeric display and a graph.
- HPVM family: screen orientation, gauge color ranges, decimal places, and gauge min/max voltage for the on-device display.
App-wide preferences that affect every device (temperature units, decimal places, screen-on behavior) live in the main Settings tab at the bottom of the app, not here.
Channel Naming (lives on the graph, not in Settings)
To rename a channel (the voltage probe, individual temperature probes, or per-channel labels on a 6-channel WVC), tap the channel's name on the graph in the main monitoring view. An Edit Channel dialog opens where you can set a custom name and (where applicable) a value range. Starting with firmware 3.10.0, channel names for the voltage probe and each temperature probe sync down to the device itself, so the new name appears everywhere: the WVC, the daughtercard touchscreen, the RTC, and connected knobs.
DEVICE Tab
Controls settings stored on the device itself. Changes here are sent to the device and persist across power cycles.
On the WVC family, the DEVICE tab has a row of small subtabs. They show icons, not names. The names below are only for this guide. The subtabs you see depend on firmware version:
| Subtab | Icon | Available when | Contents |
|---|---|---|---|
| Device Name (first subtab) | A screen | Always | Device name |
| Measurement | A ruler | Always | Probe drift, IDS mode and thresholds, competition mode, max startup volume, volume curve, Remember Volume, Temperature Unit (WVC-PRO only), Clip Detection (firmware 4.1.0+) |
| WiFi | The WiFi symbol | Always | WiFi credentials for OTA updates. See Firmware Updates. |
| Mesh Network | Connected dots | Always (on WVC family) | View and pair additional WVC units. See Multi-Unit Mesh Management. |
| Channel Groups | Sliders | Firmware 3.8.0+ | Create and assign volume groups across channels. See Channel Groups. |
| Knob Management | A remote control | Firmware 3.6.0+ | View, pair, and update wireless knobs. See Knob Management. |
| Smart Home | A house | Firmware 3.9.0+ | Connect the WVC to your home WiFi and a Matter smart home hub. See Smart Home Mode. |
If a subtab you expect to see is missing, your device may need a firmware update. See Firmware Updates.
Measurement subtab: what each control does
| Control | Description |
|---|---|
| Probe Voltage Drift | Calibration offset to compensate for voltage drop along the probe wire. Numeric entry; no enforced -5V to +5V cap. |
| Gain Level | Output gain from 0 dB to +31.5 dB in 0.5 dB steps. Only appears after you turn on the 'Enable Gain' toggle (which surfaces a DMM-measurement safety warning). On multi-group systems, per-channel gain is edited in the separate Channel Groups subtab, not here. See RCA Gain for the safety warning, gain calculator, and required DMM-measurement procedure before enabling. |
| IDS Mode | Amplifier-protection action (Off, Mute, Turn off REM pin, Mute and turn off REM pin, Limit Volume). The two REM-pin modes appear only on WVC-PRO. See Intelligent Drive System. |
| Min Voltage | The voltage threshold below which IDS triggers. |
| Max Temperature | Temperature threshold above which IDS triggers. Shown on WVC-PRO and WVC-PRO-6 only, and only when IDS is enabled. |
| Enable Competition Mode | What the base station does when no paired knob or display has been heard for about 6 seconds. Off: nothing. Mute: sets every channel group to 0 at once. Limit Volume: slowly turns every channel group down. It goes from full volume to 0 in about 10 seconds. It stops if a knob or display connects again. In both modes, the volume does not come back up by itself. One exception is a linked base station that lost the main one. It plays again once it hears the main base station. See Competition Mode. |
| Max Startup Volume | Safety cap on volume at power-on (0-100%). Firmware 3.5.0+. |
| Volume Curve | Choose how the knob position maps to output level. Five fixed presets (Natural, Linear, Audio Taper, S-Curve, Competition) with a live preview of the curve. Firmware 3.5.0+. |
Competition Mode is meant for SPL competition runs. While it is on, keep a knob, the RTC, or a display connected. A BassWatch running on battery drops its link when its screen turns off, so it does not keep your system playing. A WVC Dual PRO Knob or WVC Quad PRO Knob keeps its link with its screen off only on firmware 4.12.3 or newer. If nothing stays connected, your system mutes, or its volume slowly drops to 0. With linked base stations, update every base station to firmware 4.12.1 or newer. See Linked Base Stations.
Turn Competition Mode on while your PRO knob's screen is on. If its screen is off, the knob misses the change. If nothing else is connected, your system then mutes or turns down. Turn or press an encoder to wake the knob. Then turn the volume back up. See Competition Mode.
WiFi subtab
WVC devices can connect to a WiFi network for firmware updates and to support Smart Home Mode. Enter your WiFi network name (SSID) and password here. The app can also scan for nearby networks. The device stores these credentials and uses them when you trigger an OTA update or enable Home Mode.
WiFi-based firmware updates are significantly faster than Bluetooth-based updates. If you can provision WiFi credentials once, future updates will install in a fraction of the time.
Bluetooth Pairing Problems
If the app fails to maintain a stable Bluetooth connection to the device, a Connection Problem dialog surfaces after repeated reconnect attempts. The dialog offers two actions:
- Remove & Re-pair: clears the stale Bluetooth pairing data your phone is holding for the device, then prompts the device to re-pair from scratch. This is the "clear bonds" path most users need.
- Open Bluetooth Settings: jumps to the phone's native Bluetooth settings so you can forget the device manually if the in-app option does not resolve it.
There is no separate "Clear Bluetooth Bonds" button on the DEVICE tab; the dialog above is the supported recovery path.
SESSIONS Tab
When you are signed in, a SESSIONS tab appears showing every recording session for this device. Tap any session to open its playback view with the full chart and channel toggles. See Recording Sessions for the full workflow, plus how to view your sessions on app.lf-audio.com.
If the SESSIONS tab is missing, you are not signed in. Sign in from the main Settings tab. See Account and Sign-In.
HPVM Settings
HPVM devices have a simpler settings layout: the INFO tab shows the same kinds of fields as WVC, the APP tab covers display orientation and per-gauge color ranges, and the DEVICE tab covers probe calibration. There is no Mesh, Channel Groups, Knob Management, or Smart Home subtab for HPVM.
