GETTING STARTED
Before connecting to the KL-8, 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.
The KL-8 is powered with a 4-pin locking power supply to prevent accidental disconnection. There is no power
switch on the KL-8, once it is connected to a power source it will be active and ready for use.
Once the KL-8 is powered, begin by connecting your first keyboard to the inputs of CH-1 using standard 1/4”
instrument cables. If using a keyboard with only one output, connect to the left/mono input only, as the KL-8 will
automatically reconfigure this channel to mono.
The outputs of the KL-8 are designed to feed a PA system, recording interface, or a set of powered speakers via
balanced XLR cables. Connect the MAIN OUTPUTS to your primary audio system, and the MONITOR OUTPUTS
to a pair of powered speakers for local playback on stage. Should you encounter noise through the PA or your stage
monitors, engage the ground lift switches on the rear of the KL-8 to help eliminate the problem.
Start with the Main and Monitor outputs set to around 2 o’clock, and the level control on CH-1 turned down to around
9 o’clock. Engage the ON switches to activate the first input and both outputs and slowly turn up the level on CH-1
until you reach the desired output level for your first keyboard. Repeat the process on CH 2-4 with your remaining
keyboards, using the input level controls on each channel to adjust the balance between all four keyboards. Once
you have achieved this balance between your keyboards, you can adjust the Main and Monitor output levels as
needed to control the overall volume on stage or through the PA system.
