Low Latency Wireless Guitar System: This system uses advanced technology for low latency. The effective transmission range of the guitar system is within 30 meters (Note: up to 30m when facing the transmitter/receiver, and up to 15m when facing away).
No Interference: Supports 1-to-1 mode to prevent interference with each other. Uncompressed, high-quality wireless signal transmission maintains pure sound effects during performance, providing a reliable and stable signal for guitars and other electronic instruments. Long-lasting Operation: Built-in large-capacity rechargeable battery provides over 6 hours of use on a full charge.
The included Type-C cable can charge two devices simultaneously, taking about 4 hours for a full charge. (Note: The transmitter consumes more power than the receiver as it needs to receive signals and transmit the source simultaneously.)
Wide Applicability: The electric guitar amplifier is designed with a 280° rotatable 6.35mm mono audio plug, allowing for free adjustment of its position. Suitable for acoustic-electric guitars, electric basses, drums, electric pianos, and other instruments. Multi-functionality: Six sets of wireless systems can be used simultaneously in the same environment.
Additionally, one transmitter can be paired with up to six receivers simultaneously (products of the same model). How to Use: For the first connection, press and hold the pairing key on both the transmitter and receiver for 3 seconds simultaneously to enter pairing mode. The lights will flash, and they will automatically connect in about 3 seconds.
