FAQ

1.If the conference has hundreds of participants, can the number of receivers be increased indefinitely?
Yes. The L7 system supports unlimited receivers paired with one transmitter, and we can provide batch customization based on the conference scale (no signal attenuation even with large quantities).
2.Will the device be interfered with by the conference's existing audio equipment (e.g., wireless microphones)?
No. The L7 uses a 2.4GHz high-frequency band that is different from the frequency of common conference audio equipment, effectively avoiding signal interference.
3.Can the battery last for a full-day conference (about 8 hours)?
Yes. The receiver's battery life is ≥8 hours, and the transmitter's is ≥20 hours. We also provide portable charging boxes for emergency charging during long conferences.
4.Is the receiver easy to distribute and collect after the conference?
Yes. The receiver is lightweight and small, and can be stored in a dedicated storage box (e.g., HM-50S aluminum storage box holds 50 receivers) for unified distribution and collection.
