WL-20L: No Cable Tone Simulation The WL-20L model is functionally identical to the WL-20, with the exception that it eliminates cable tone simulation. This makes it the best choice for instruments where cable capacitance has little or no effect on the tone, such as an acoustic/electric guitar with an onboard preamp, a guitar or bass with active pickups, or a line-level device like a keytar or Roland’s Aerophone digital wind instrument. The WL-20L also works great with passive pickups if you don’t need the subtle treble roll-off provided by cable tone simulation. Plug-and-play wireless systems for guitar, bass, and other electronic instruments No complicated setup required—simply dock the transmitter and receiver together for about 10 seconds to set the optimum wireless connection Newly developed BOSS technology delivers premium audio performance with rock-solid stability, ultra-low latency (2.3 ms), and 50-foot/15-meter range (line-of-sight propagation)* Built-in rechargeable batteries provide up to 12 hours of continuous playing time** Simple charging with a standard USB adaptor (5 V/500 mA or greater) Cable tone simulation reproduces the natural capacitive effect of a 10-foot/3-meter guitar cable (WL-20 model only) Spare WL-T Transmitter available separately * The transmission range may vary due to local conditions. ** A full charge provides 12 hours of time for the transmitter and 10 hours for the receiver. Lightning-Fast BOSS Wireless Technology Equipped with high-performance BOSS wireless technology that debuted in the Katana-Air wireless guitar amp, the WL-20 series delivers exceptional sound quality with wide dynamic range. Working in the 2.4 GHz frequency band, the optimum channel is set automatically to ensure rock-solid audio performance with absolutely no drop-outs. And with ultra-low latency of just 2.3 ms, you’ll always enjoy great playing feel with no lag whatsoever. Up to 14 BOSS wireless systems can be used simultaneously in one space, allowing multiple musicians to enjoy wireless freedom at the same time.* *Environmental conditions may affect the actual number of simultaneous systems available. Automatic Wireless Setup With the WL-20 series, there’s no fiddly channel setup required. Just dock the transmitter and receiver together for about 10 seconds to automatically set the optimum connection. Plug In and Rock A WL-20 system is literally as simple to use as a standard guitar cable. The small transmitter plugs into your instrument, while a matching receiver plugs into a pedal or amp. That’s it! Easy Charging via USB When docked, the built-in batteries in the transmitter and receiver can be charged together with a standard USB adaptor (5 V/500 mA or higher), the same type used with the latest smartphones and tablets. The transmitter and receiver can also be charged separately, and a micro USB cable is included for charging.
