Connectivity & Controls

• Stereo Inputs: Connects your analog keyboard to the Key-Largo
• Effects Send & Receive: Insert jacks used to feed an external effects device
• USB Type-2: High-quality USB I/O for Mac or PC
• Volume Pedal Send & Receive: Stereo TRS insert jacks for a master volume pedal
• Monitor Output: Stereo 1/4'' TRS balanced outputs are used to feed a pair of self-powered speakers for on-stage monitoring
• Main Output: Stereo XLR balanced outputs are used to feed the PA system (transformer-isolated to eliminate ground loops)
• MIDI In & Out: In and Out connections to send and receive MIDI over USB
• Sustain 1/4'': Connect your sustain footswitch to the Key-largo and your keyboard or digital piano
• Level Control (1, 2, 3): Adjusts the input levels of your three analog keyboards
• USB Level Control: Used to adjust the USB audio return from your laptop
• EFX Send: Individual controls on each channel are used to set the desired amount of effect that will be applied to each device
• EFX Return: Master effect return control, used to optimise the effects loop signal path
• Effects Footswitch: Latching footswitch turns the effects loop on or off
• Sustain Footswitch: Momentary footswitch activates the sustain function on a master keyboard or digital piano
• Monitor Out: Adjusts the stage volume for the keyboard monitors
• Main Out: Sets the Key-Largo output level going to the PA system
• Effects Loop Mono: Switches the effects loop from stereo to mono when pushed in
• Sustain Footswitch Polarity: Enables the Key-Largo sustain footswitch function to work with various keyboards
• USB Assign: Configures the Key-Largo for live performance use or as a recording interface
• Monitor/Main Ground Lift: Helps eliminate buzz and hum caused by ground loops
