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.
