OVERVIEW The Key-Largo is a compact keyboard mixer that also includes the realtime performance attributes of a footswitch controller, allowing you to easily create an exciting and professional performance on stage. The best way to approach the various features of this powerful device is to break each section down into modules before addressing the Key-Largo as a whole.
FEATURES 12 11 1 10 2 9 3 4 5 6 7 8 1. EFFECTS LOOP MONO: Switches the effects loop from stereo to mono when pushed in. 2. EFFECTS FOOTSWITCH: Latching footswitch used to turn on or off the effects loop in order to add echo or reverb when soloing. 3. EFX SEND: Individual controls on each channel are used to set the desired amount of effect that will be applied to each device. 4. LEVEL CONTROL (1, 2, 3): Used to adjust the input levels of your three analog keyboards. 5.

EFFECTS SEND & RECEIVE: Stereo ¼” TRS jacks used to feed an external effects device. 15. MONITOR OUT: Stereo ¼” TRS balanced outputs are used to feed a pair of powered speakers for on-stage monitoring. 16. MAIN OUT: Stereo XLR balanced outputs are used to feed the PA system - transformer isolated to eliminate ground loops. 17.
MAKING CONNECTIONS Before connecting to the Key-Largo, it is always best to turn your audio system levels down in order to prevent plug-in transients that could damage more sensitive components such as high frequency drivers. It is also a good idea to test at low volumes before turning up. This way, should a cable not be properly seated, making a live connection will be safer. The Key-Largo is powered via a 15VDC center-pin positive supply.
USING THE KEY-LARGO There is no power switch on the Key-Largo, as soon as you connect the power supply the ON light on the front of the unit will illuminate and the Key-Largo will be active. Connect your first keyboard to INPUT-1 Left and Right (if using a keyboard with only one output, connect to the Left/Mono input, the KeyLargo will automatically reconfigure this channel for mono), then connect the MAIN OUT to the PA or a set of powered speakers via XLR cables.
GOING DIGITAL The Key-Largo features a Type-B USB connection, and requires a USB 2.0 cable to connect to the port on your computer or laptop. This is a common ‘TYPE A to TYPE B’ cable that is compatible with the majority of printers, hard drives and audio interfaces. TYPE B USB Used to connect to the Key-Largo TYPE A USB Fits most laptops and computers If using with a Mac, the Key-Largo is plug-and-play, with no drivers required.
THE EFFECTS LOOP The Key-Largo is equipped with an effects loop to allow you to share outboard effects units across all of your keyboards. This feature can be used with both mono and stereo effects, as well as with pedals or rackmount equipment. A latching footswitch turns the loop on and off, so you can quickly add in a delay or a chorus and have it affect each keyboard as much or as little as you want. For mono effects, engage the recessed switch on the left side of the KeyLargo.
ADDING SUSTAIN The Key-Largo features a dedicated footswitch to act as a sustain pedal for one of your keyboards. This is a momentary non-latching switch, so it will only apply sustain when you are physically pressing down on the switch. Connect the SUSTAIN OUT to the Key-Largo to the connection on your keyboard for a sustain pedal. Test by playing a note and holding down the sustain footswitch.
USING WITH MIDI The Key-Largo can send and receive MIDI information over USB, allowing you to use a controller to play a soft-synth on your laptop, or record and playback MIDI using your computer’s digital audio workstation (DAW). The Key-Largo doesn’t generate MIDI information on its own, nor can it be controlled via MIDI; it simply transmits the information between the MIDI and USB connections.
RECORDING VS. LIVE MODE The Key-Largo has two modes, set via the USB ASSIGN recessed control on the side of the unit. When this switch is disengaged the Key-Largo is set to LIVE mode. This means the USB audio from the computer is treated like any other keyboard input; you can send it to the effects loop, blend it with the other keyboard inputs, and control it with an external volume pedal.
