• Neighborhood events, school events, sports days
• Training sessions, classes, seminars
• Outdoor events, flea markets, street calls
• Quiz nights, game nights, karaoke
ALL YOU NEED
Your usual mic + iPhone + Bluetooth speaker
No amp, no mixer, no computer. Use the wired mic you already own — USB or 3.5 mm.
FEATURES
• Wired mic as the input: a wired mic (USB or 3.5 mm) is selected automatically, and you can also pick the input yourself.
• Mic gain (up to +48 dB): some mics are quiet. Raise the level in the app even if your mic has no volume control.
• Feedback protection: warns you when feedback is detected, then lowers the volume by half or mutes — your choice. Sensitivity is adjustable.
• Noise cut: removes low rumble and quiets the output while you aren't speaking. Adjustable threshold.
• ○ × sound effects: play a "ding-dong" or a "buzzer" with one tap. Great for quizzes, training and games.
• Script page: write your MC script and show it in big text on stage. On iPad, the script and the mute / sound-effect controls sit on one screen, so you can read and operate at the same time. Auto-scroll lets you speak while looking at the page. Your script stays on the device.
• Mute and volume: one screen with big buttons.
• Keeps working with the screen off.
• Languages: Japanese, English, Korean, Simplified Chinese.
PLEASE NOTE
• Because of Bluetooth, there is a delay of about 0.2–0.5 seconds before your voice comes out of the speaker. If you can hear the speaker return your own voice, it may be distracting. Place the speaker away from the person speaking.
• If the mic is close to the speaker, feedback will occur. Feedback protection is an aid — please also mind the volume and placement.
• The iPhone's built-in speaker is not used (to avoid feedback). Choose a Bluetooth speaker or similar.
• Tested devices: tested with UC02 (USB).
• How iPhone recognizes a device differs by mic and adapter. We cannot guarantee operation with every device.
• The 3.5 mm mic jack on some cheap USB hubs may not pick up sound from some mics.
• Pair your Bluetooth speaker in iPhone Settings first.
• There is no recording feature. Audio is only processed on the device — it is never saved or sent.
HOW TO USE
1. Pair your Bluetooth speaker in iPhone Settings.
2. Connect your wired mic to the iPhone (USB or 3.5 mm).
3. Check the input and output in the "Connection" tab.
4. Tap "Start" in the "Play" tab.
