Key-Largo Keyboard Mixer
The Key-Largo is a keyboard mixer with the performance attributes of a real-time footswitch controller! Designed for stage use, the compact design features three sets of ¼” analog inputs for standard keyboards, along with a USB interface to connect a laptop when using a soft-synth. Each stereo input is equipped with a level control and an effects loop to activate an echo or reverb when soloing. A built-in momentary sustain footswitch lets you connect the Key-Largo to your master keyboard, eliminating the need to bring a separate sustain footswitch to the gig! Outputs are provided over ¼” connectors for powered speakers on stage, as well as transformer-isolated XLR outputs to feed the PA. With both USB and MIDI connectivity, the Key-Largo easily integrates with all types of keyboard setups. High quality 24bit/192kHz converters allow playback of the best sample libraries and soft-synths, and also provide the ability to record over USB with excellent audio quality. This means the Key-Largo can also be used as a robust recording interface, ideal for recording tracks when on the road or capturing your live performance.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.https://www.youtube.com/watch?v=U74v4GR-N94
