BOSS Gigcaster 5-Channel Audio Streaming Mixer

All-in-One Audio Hub for Streaming Musicians
Gigcaster 5 is a powerful all-in-one audio command center purpose-built for musicians who livestream and create audio and video content. It provides a host of advanced features in a space-saving desktop interface, including premium audio connectivity and live operation via hands-on controls and a vivid color touchscreen.

Plug in a guitar or bass and play with flagship-level GT amps and effects. Connect mics and shape voices with studio-grade processing from the VE series. And bring in another instrument using the stereo line input. You can mix up to five sources as you stream, including background music and sound from a remote guest or student. Adding in customizable features, external control support, and more, Gigcaster 5 is an essential partner for music performers, remote educators, podcasters, and anyone creating music-focused media.

Killer Guitar and Bass Sounds, No External Gear Needed
With Gigcaster 5, you can stream and jam with impressive guitar and bass tones without the need for external processing. Just plug into the front-panel jack and start rocking with premium amps and effects ported from the top-line GT-1000. Versatile preset patches provide 100 ready-to-play sounds, while 200 user locations are available for storing parameter tweaks and custom-built setups. A built-in tuner is always at hand, a vital tool for every session. And with extensive control support via footswitches, expression pedals, and the GA-FC or GA-FC EX, you can operate your rig hands-free as you perform.

Perform with Mics and Other Instruments
Gigcaster 5 also features inputs for additional gear and playing along with other musicians. Tap into broadcast-quality XLR mic sounds with two low-noise preamps, wide dynamic range, and phantom power support. And use the stereo line input for an instrument such as a keyboard or drum machine. Dedicated vocal effects from the popular VE series allow you to sing with effects like compression, pitch correction, delay, and reverb, and you can even dial up harmonies that automatically follow a set key. Effects are also available for speaking-including fun transformer effects that change the sound of your voice-along with console effects to enhance the sounds of connected sources.

Pro Multichannel Audio Mixing
Gigcaster 5 puts a deep array of mixing and audio routing features at your fingertips. Along with the three analog input channels, there are dedicated stereo channels for Bluetooth® and USB audio, and each mixer channel includes a variety of sound-shaping options for pro mixing on the fly. Gigcaster 5 can also communicate with multiple computer audio channels over USB, providing lots of flexibility for different streaming applications and working with remote guests, DAW music tracks, game audio, and more.

Compact Streaming Power
The compact Gigcaster 5 delivers a host of real-time creative tools while taking up minimal desktop space. You can play music from a mobile device via Bluetooth, and there's a ducking function to automatically reduce the volume as you speak over it. When connected with the Gigcaster 5 App, it's possible to trigger theme songs, sound effects, sample loops, and backing tracks with touches on the display as you stream. Eight pads and eight pad banks provide a total of 64 on-demand sounds, which you can easily configure and organize into libraries within the app.

Grab-and-Go Control
With the color touch display and intuitive panel controls, you can operate Gigcaster 5 using nothing but the hardware. Mix sources with the faders and mute buttons, view signal levels on screen, quickly access and edit effects, and apply noise suppression, de-essing, and other tools for a polished sound. You can go even further with the Gigcaster 5 App, tweaking various parameters on your computer's screen as you work.

Customize Your Workflow
Gigcaster 5 offers many configurable features to suit any streaming style. Eight onscreen effect padsconfigured in eight banksgive you 64 command sources for quick sound changes from the touch display. Up to four effects controls can be assigned to each pad, including preset selection, bypass, and more. It's also possible to control pad assignments via external footswitches for hands-free access. MIDI over USB is supported as well, providing advanced control of music, video, and streaming applications that respond to MIDI commands.

(Model# GCS-5)


Awesome music shop! Very clean, not crowded. Lots of guitars for everyone's musical taste. The staff is super nice, and very informative. I can't say enough good things about Picker's Alley! Thank you so much for serving Southwestern Ontario with such awesome service!!

Pat P

Great music store. Messaged them about a sale item and they put the last one aside for me until I could get there to purchase.

Tim Clements

Tony is by far the best customer service rep around, He knows his stuff, and is always willing to go above and beyond, I only go to pickers alley, for all my musical needs!!

Ryan Mathews

Excellent service, in one word they know what they are doing just tell them your requirement and budget. Don't worry about price if you see it online it's the same price here in offline too. Best thing is the owner's humour and focus on your requirement more than the sales of the store.

Very very happy and satisfied and will be back for additional requirements.

Adhish Prasai

What a great selection of guitars and amps. Staff is very knowledgeable and friendly. If they don't have what you need chances are they can source it for you. Prices are as competitive as big box music stores so there is no need to look elsewhere. I will continue to support local when I can.
