SWIFF AUDIO - WT-09B

The WT‑09B is a next-generation wireless transmission system designed for musicians who want to move freely on stage or in the rehearsal room without sacrificing the tonal quality of their instrument. It's part of the Master Series and is an evolution of the WT‑09A model, designed to offer an immediate user experience for guitarists, bassists, and instrumentalists seeking transparent and natural sound, rapid response, and total reliability. It's particularly suitable for soloists, small ensembles, and live situations where tonal fidelity and connection stability are crucial.

The system consists of a compact, lightweight, and easy-to-use transmitter and receiver. Lossless transmission preserves the instrument's original character, while latency of less than 5.5 ms ensures an immediate response that doesn't alter the playing feel. Operation in the 5.8 GHz band with intelligent frequency selection ensures a stable connection even in crowded environments, automatically choosing the clearest of six available channels. The transmission range is 60 meters, while in open environments free of interference or obstructions, the transmission distance can reach up to 120 meters! The compact body is designed to withstand daily use, with an ergonomic design that easily adapts to any instrument and ensures stability even during dynamic performances.

Automatic power-on and pairing make use extremely simple, with optimized compatibility for instruments with passive pickups and the ability to use up to four systems simultaneously without interference. Built-in RGB indicators allow you to quickly check the device's status even in low-light conditions, making the WT-09 a reliable companion for any situation.
