ROLAND WL-20L Low Impedance Wireless System

Description

ROLAND WL-20L Low Impedance Wireless System

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.
