Boss WL-20L Wireless System for Guitars or Line-Level Devices
The BOSS WL-20L is a wireless system for electric guitarists and other electronic musicians. It provides easy operation through its plug-and-play user experience. Simply plug the included WL-T transmitter into your guitar or line-level instrument (keytar, digital wind instrument, etc.), and plug the receiver into your amplifier, first pedal in the chain, or pedalboard input; or if you are using a line level device, plug into a mixer or PA. Now, you are free to roam up to 50' away from your amp without worrying about dragging gear, tripping up your bandmates, or accidentally unplugging yourself.
The receiver automatically finds and sets the optimal wireless connection with the transmitter, selecting among 14 channels to do so, and operating over the carrier frequency of 2.4 GHz. At 2.3 ms, latency shouldn't be an issue. A USB charging cable is included, with which you can charge both the receiver and transmitter. To do this, plug the transmitter into the receiver, connect the charger to the DC-in port, and both units will be charged in around 4 hours. From there, you'll get approximately 10 hours of continues playing time.
This model differs from the WL-20 by not offering cable-tone simulation. Without the high-freqeuncy roll-off that mimics the capacitive effect of 10' guitar cables, the system is well suited for instruments with active pickups and onboard preamps, or line-level devices.
