Manufacturer's Description from Radial

The Key-Largo is a unique and powerful device that combines a multi-channel keyboard mixer with a USB audio interface, while providing the ability to control elements of the performance with footswitch control.

  • Three stereo analog inputs for keyboards

  • Digital USB connection for laptop soft-synths

  • On-board sustain and effects loop footswitches

  • Separate balanced outputs for the PA and stage monitors

 

A mixer for today's gigging keyboard player

Designed for stage use, the Key-Largo allows you to connect up to three stereo keyboards, effects and volume pedals, and a laptop computer via USB, managing all these signals to send a balanced audio feed to a PA system for a seamless performance on stage. Three stereo analog inputs feature individual volume controls to balance levels, and each can be sent to a shared effects loop to add reverb or delay in an instant using a dedicated footswitch. A USB connection allows laptop computers to be integrated into the setup for control of soft-synths, and a built-in sustain footswitch and connections for a stereo volume pedal provide additional ways to control your performance.

 

High headroom, low noise

A switch-mode power supply inside the Key-Largo elevates the rail voltage to 24 volts for extra headroom to handle the most dynamic digital keyboards and the hottest analog synths without fear of overload or distortion. This is paired with 24bit/192kHz digital audio converters for high quality audio over USB when playing soft-synths or pre-recorded tracks. To eliminate noise when connecting multiple devices on stage, the main outputs are transformer-isolated to eliminate hum and buzz from ground loops, and all outputs are equipped with ground lift switches to further reduce noise.

 

Manage a multi-keyboard setup with ease

The Key-Largo effortlessly mixes multiple keyboard outputs down to a stereo feed for the PA system over XLRs. Add more excitement to the performance with a switchable effects loop and master volume pedal.

 

Integrate a soft-synth on stage

The Key-Largo can take the MIDI output from a controller to play a soft-synth on your laptop. High quality digital-to-analog converters give you great sound quality on local monitors and at the PA system.

 

Combine analog and digital on stage

Mix three keyboards together with the output of a laptop soft-synth, making the Key-Largo the center of your performance setup. Connect a ¼” cable to the footswitch input on your main keyboard to utilize the Key-Largo as a sustain pedal, fully implementing the many features of this powerful pedal.

 

The Key-Largo as a recording interface

24bit/192kHz converters provide more than just high quality playback on stage, the Key-Largo can also be used to record pristine tracks using your favorite audio program. This allows you to easily record studio-quality tracks while on the road, or to capture your live performance.
