Device Settings

basic

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 (editable on the DEVICE > Common subtab).
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.
Note

Some fields only appear for specific device models. For example, CPU2 firmware only shows on devices with a secondary processor (the WVC family).


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.
Tip

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 uses an icon-bar to switch between subtabs. The exact subtabs available depend on firmware version:

Subtab Icon Available when Contents
Common display_settings Always Device name
Measurement straighten 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 wifi Always WiFi credentials for OTA updates. See Firmware Updates.
Mesh Network hub Always (on WVC family) View and pair additional WVC units. See Multi-Unit Mesh Management.
Channel Groups tune Firmware 3.8.0+ Create and assign volume groups across channels. See Channel Groups.
Knob Management settings_remote Firmware 3.6.0+ View, pair, and update wireless knobs. See Knob Management.
Smart Home home Firmware 3.9.0+ Connect the WVC to your home WiFi and a Matter smart home hub. See Smart Home Mode.
Note

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.
Competition Mode Bypasses voltage-based shutdown for competition use.
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+.
Warning

Changing Competition Mode disables important safety protections. Only enable this for supervised competition use.

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.

Tip

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 GATT cache and the Android-side Bluetooth bond, 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.
