The Triple-Stereo Mega Looper!
With loop mania sweeping the globe, BOSS proudly announces the most powerful Loop Station ever brought to the market — the RC-300. The new flagship looper features three synchronized stereo tracks with dedicated volume knobs and transport-control footswitches for each track. It’s also equipped with pro effects, a master Expression pedal, and a deluxe, ultra-wide control panel for the ultimate in live-performance manipulation. Plug in your guitar, bass, keyboard, or instrument of choice and create amazing loops in real time. An XLR input is also provided, complete with phantom power, so singers, percussionists, violinists, beatboxers, or anyone with a mic’d instrument can get in on the act, too. The RC-300 lets you record for up to three hours directly to its internal memory, adding effects as you go. The USB port lets you save your loops externally, as well as import/export WAV files. Step into the most powerful and inspiring Loop Station in BOSS history. It’s the creative powerhouse that musicians have been dreaming of!
Create, stack, and manipulate multi-layered loops with the RC-300’s three stereo tracks — each track being independently controllable. The “Auto Recording” feature starts recording the moment you begin playing your instrument, or as soon as you start a connected audio player. Count-In mode gives you one-bar of rhythm before recording starts. You can Undo/Redo as you go. The sky’s the limit with three hours of recording time!
The RC-300’s ultra-wide pedalboard is equipped with an Expression pedal (which can be assigned to a variety of parameters) and enlarged footswitches for controlling REC/PLAY and STOP for each track. There’s also a master ALL START/STOP footswitch onboard. Additionally, three independent faders provide immediate control of each track’s output volume. And if that’s not enough control under your hands and feet, you can also connect external Expression pedals and footswitches (sold separately).
Process your tracks and external-input signals with the RC-300’s expressive onboard effects, including Transpose, Flanger, Phaser, Modulator, vocal effects, and more. A dedicated LOOP FX footswitch is provided for instant activation of the onboard effects. Control the effects parameters in real time with the Expression pedal for hands-free creativity onstage. You can apply the effects to any single track as well as to the entire mix, expanding your creativity and musical expression.
To keep your loops tight and in time, you can play along with one of the cool rhythm patterns in the RC-300’s onboard library as you record; the Loop Quantize feature helps you having your recordings looped in time. Dozens of rhythm types are onboard, including rock, pop, shuffle, Latin, and more. A dedicated knob lets you adjust the volume of the rhythm, and you can set the tempo incrementally or via tap tempo. You can also specify the time signature. When you save a phrase, the rhythm type and time signature will also be saved. To get you up and running right away, the RC-300 comes preloaded with audio backing tracks (including bass tracks, piano tracks, etc.) for instant play-along performance and fun.
Connect the RC-300 to your computer via a standard USB cable, and back up your phrases externally for safekeeping. You can import and export WAV files between your computer and the RC-300; 16-bit/44.1kHz WAV files of up to 1.7GB in size can be imported.
