Connect your powered-on AudioLai speaker using a USB data cable, then select it in the browser window.
Connect the speaker to read all settings.
Playback controls
Status not readCurrent volume
Volume is shown in dB. A lower value means a quieter level. 0 dB is a reference level, not silence. Use Mute to silence the speaker. The large value is the last volume read from the speaker.
Changing the volume can turn the audio back on, even while Mute is active.
The slider prepares a value. Press Apply volume to send it.
Active preset
P1, P2 and P3 recall the listening configurations already stored in your speaker. Switching presets activates the saved sound settings and the input assigned to that preset.
Choose the input connected to your audio source. Auto searches for an input with a signal. Press Apply input to save your choice for the active preset. Only use inputs fitted to your speaker.
While selecting or searching for an input, the speaker may mute the audio. Refresh status to read its current state.
The selected input is assigned to the active preset. Auto searches for a signal. Choose an input fitted to your speaker.
Signal levels
Digital signal levels reported by the speaker, not room loudness.
Connect your speaker to read its status and use the controls.
For standby and power on, use your speaker’s remote. These controls are not available in the app yet.
Power and standby settings
Not read from speakerChoose how your speaker starts and responds when the audio signal stops or returns.
The fields show settings read from the speaker. Different choices are local drafts only: saving these settings to the speaker is not available yet.
Connect the speaker to read its current advanced settings.
Enter a start-up volume between −96 and +18 dB.
A fixed value sets the level at each start-up. “Use the last listening volume” recalls the level used before switching off.
Choose whether the speaker starts immediately when mains power returns, or waits for a wake-up command.
Automatic standby and wake-up
Signal detection combines automatic standby after silence with wake-up when audio returns. The mains power setting above is separate.
Enter a whole number of minutes from 1 to 180.
From 1 to 180 minutes without a detected signal.
Level 1 is the most sensitive, level 4 the least. Keep OFF at or below ON. Digital wake-up uses a fixed detection threshold.
Choose ON and OFF from 1 to 4, with OFF less than or equal to ON.
Listening and lighting
Local draftCurrent settings are shown when available. Changes stay in a local draft; saving to the speaker is not available yet.
Digital channel and preset levels
On speaker: not read
Choose which channel of a digital stereo signal this speaker uses.

Adjust the relative level of each preset from −24 to +24 dB. This is separate from the listening volume.
Speaker LEDs
Set the standby LED brightness. The active LED has a fixed hardware brightness on these speakers.
On speaker: not read
The speaker firmware does not provide a separate active LED brightness control.
No listening or lighting draft prepared. Nothing has been sent to the speaker.
Input equalizer
Speaker saving is currently unavailable. You can read supported settings and prepare local changes; editing alone does not change the sound.
Speaker EQ not read
Reading details
Shape the sound with nine bands for each preset.
Choose which preset to read or edit. The playing preset stays the same.
Connect the speaker to read its saved EQ.
Connect the speaker to load its EQ, or prepare a local curve.
Some speaker values cannot be edited here. Available values are kept unchanged.
Band 1
Use 20–20,000 Hz, −15.9 to +15.9 dB and Q 0.1–20. Frequency accepts two decimal places; gain and Q accept three. Invalid edits keep the last valid curve.
Frequency chooses the area to adjust; Gain boosts or cuts it; Q controls its width. A higher Q makes a bell band narrower. You can also drag a point on the graph.
EQ files and browser copy
Save this preset’s EQ in a named file on your computer. Loading a file replaces the selected preset’s local curve; it does not change the speaker.
To use this EQ on a slave, connect that speaker, read its settings, then save the selected preset.
Keep a separate copy in this browser. This does not save it in the speaker.
Frequency response
First version · to validateMeasure your speaker in your room. Compare up to three curves at the same microphone position.
Relative response only: this is not a calibrated sound-pressure meter. For reference, compare the first measurements against REW.
The speaker’s USB port carries controls, not test audio. Connect the computer’s audio output to an audio input on the speaker. USB speaker control is optional for this measurement.
1Microphone and calibration
Allow microphone access, then choose your UMIK-1. Recordings are processed on this computer and are not uploaded.
Load the file for your microphone’s serial number and the selected orientation. The app cannot verify that they match your physical microphone.
No calibration loaded.
Select the DAC or audio interface connected to your speaker. Measure one speaker at a time.
2Check the level
Start with a low speaker volume. dBFS is the digital test level, not the loudness in the room. Turn off audio enhancements in the computer’s sound settings.
Microphone off.
Complete a level check before measuring.
3Measure and compare
Stay quiet and keep the microphone still. A six-second sweep is followed by three seconds to capture the room decay. Sound stops when you leave this page.
Ready when microphone, calibration and level check are complete.
The curve includes the room, speaker and audio path. Gaps mark frequencies too close to the background noise. Curves show tonal differences, not absolute loudness differences.
Curves stay in this page until it is reloaded. Export them to keep a copy. Measurement does not change the speaker’s EQ.
