Radial Engineering Key-Largo

With unmatched features for a compact mixer of its size, Radial Engineering's Key-Largo sports three stereo input channels, software instrument streaming over USB, balanced outputs, and so much more. At its most basic level, Key-Largo can serve as a mixer for three stereo instruments, such as keyboards and synthesizers, with dedicated volume controls and effects send level for each. The onboard effects loop, which may be switched on and off through the dedicated footswitch, is configurable between mono and stereo operation, and there's also a secondary loop for connecting a volume pedal. As four outputs, Key-Largo sports both TRS jacks on the Monitor outs, as well as isolated XLR outputs for PA systems.

Perhaps one of the neatest things about Key-Largo though is its USB connection, which is configurable for streaming audio into the dedicated USB channel on the mixer, or recording your mix of instruments to your DAW. For added convenience, 5-pin MIDI input and output ports allow you to pass notes and control data from your main keyboard to software instruments over the USB connection. Finally, there's also a momentary sustain switch which may be used instead of a traditional damper pedal. Key-Largo is the ideal keyboard mixing solution for modest rigs with a touch of sprawling tendencies.
