Break free from the constraints of traditional cables with the WL-20L wireless system, engineered to give musicians unprecedented freedom without compromising on sound quality. This ultra-compact wireless solution harnesses BOSS's cutting-edge technology to provide premium audio performance with rock-solid stability and an impressively low 2.3ms latency. The plug-and-play design means no complicated setup procedures - simply dock the transmitter and receiver together for 10 seconds and you're ready to perform with complete wireless independence.
The WL-20L stands apart from its sibling model by eliminating cable tone simulation, making it the perfect match for instruments where cable capacitance has minimal tonal impact. This includes acoustic/electric guitars with onboard preamps, instruments fitted with active pickups, and line-level devices such as keytars or Roland's Aerophone digital wind instruments. Musicians using passive pickups who prefer a cleaner signal path without the subtle treble roll-off will also find this model ideal for their needs.
Built with the same high-performance wireless technology that debuted in the Katana-Air wireless guitar amp, the WL-20L operates in the 2.4 GHz frequency band with automatic channel optimisation for consistent, drop-out-free performance. The system offers a practical 15-metre line-of-sight range and boasts rechargeable batteries that provide up to 7 hours of continuous playing time. With support for up to 14 BOSS wireless systems operating simultaneously, entire bands can enjoy wireless freedom together, opening up new possibilities for dynamic live performances and effortless sound checking from anywhere in the venue.
