The Radial Engineering Key-Largo is a unique device that combines a multi-channel keyboard mixer with the performance attributes of real-time footswitch control and a stereo direct box.

Designed for stage use, the ultra compact design features three dual ¼" analog inputs for standard performance keyboards along with a USB interface to connect a laptop when using a soft-synth. Each stereo input is equipped with an individual level control for quick onstage adjustments along with an effects loop to interface and external multi-effects device. The effects loop can then be turned on or off using the built-in footswitch to activate an echo or reverb when soloing. The effects bus is stereo but may be summed mono when using guitar style pedals. To add even more fun to the performance, a built-in sustain footswitch lets you connect the Key-Largo to your master keyboard or digital piano using a standard guitar cable, eliminating the need to bring a separate sustain footswitch to the gig.

As with all Radial products, the Key-Largo is made tough and sounds great! It features solid 14-gauge steel construction with steel shafted potentiometers and switches to handle the abuse of being on the road. Inside, a switch-mode power supply elevates the rail voltage for extra headroom to handle the most dynamic digital keyboards and fattest analog synths. Separate monitor outputs allow the artist to adjust the level on-stage while the balanced XLR main outputs provide a separate DI connection to the PA system. The main outputs are transformer isolated to eliminate hum and buzz caused by ground loops and all outputs are equipped with a ground lift switch to further abate noise.

With both USB and MIDI connectivity, the Key-Largo easily integrates with all types of keyboard setups. And the high quality 24bit/96kHz converters make it ideal for recording tracks when on the road.
