Get to know them!

The Mackie ShowBox offers live performers a multifaceted, supremely capable battery-powered speaker with all the built-in trimmings needed to put on an attention-grabbing performance. To start, this 400-watt, 6-channel powered speaker houses two hi-Z inputs for acoustic, electric, or bass guitar, two XLR inputs for microphones, and a pair of stereo inputs, ready to project your next solo or small band act with ease. Live performers here at Sweetwater thoroughly enjoy the adaptability of the ShowBox's breakaway mix control, which can be controlled directly from the speaker itself or mounted to a microphone stand for instant access to all parameters. With onboard digital effects, live recording to a microSD card, and streaming options to your favorite smart device, the Mackie ShowBox is your all-in-one solution to make any space on the planet your stage.

A veritable jack of all trades

Mackie designed the ShowBox to tackle any performance. First, it functions principally as a clear, clean acoustic guitar amplifier for busking. Meanwhile, the microphone inputs, two hi-Z instrument inputs for guitar or bass, and line-level inputs offer enough connectivity to be a portable PA for small groups and solo artists. ShowBox offers amp and PA voicings to shape your sound for either application, an outdoor mode, and feedback elimination. Furthermore, the built-in effects allow you to customize your sound with a variety of options, including Fuzz, Distortion, Reverb, Delay, and Chorus, or add your pedalboard with the FX Send and Return. Record your performance to an SD card or record and livestream straight to your smartphone with ShowBox’s built-in USB-C interface.

Convenient performance tools

Getting a Mackie ShowBox up and running is extremely easy. Connect your gear to the mixer, and the Autogain feature ensures you have proper levels. Best of all, the ShowBox comes with a breakaway controller you can mount to a microphone stand. With the breakaway controller, you get hands-on control over every parameter without having to go back to the speaker and make the tweaks. The controller has various knobs for adjusting input levels, effects and EQ, compression, the looper, the onboard tuner, presets, and more.

Connects to your smartphone or computer

Nearly every performer has a smartphone, a nd the ShowBox’s onboard Bluetooth allows you to stream backing tracks or intermission music directly from the smartphone in your pocket. Want to record your upcoming gig? No problem. The ShowBox makes it happen in two ways. First, the microSD card slot offers onboard recording. Second, you can plug your computer into the USB-C port and record straight into your DAW. The USB-C port even gives you the ability to livestream your performance via a compatible streaming device.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.
