[. . . ] Connect left output of your keyboard to the left input of the KB5/KB4 and connect right output of your keyboard to the right input of the KB5/KB4 5. Adjust the channel level for proper volume 9. ) Caution: Excessive low frequency boost causes greater power consumption and increases the possibility of speaker damage. Controls the high-impedance microphones or other high-level sources equipped with a 1/4" phone plug. Controls the low-impedance microphones or other low-level sources equipped with a male XLR connector. This affects what signal is sent to the headphones. When in the OUT position, only the signal from channel 5 is sent to the headphones. Great when you need to hear a click track or midi/pre-recorded track. When engaged (IN position), the headphones are sent signals from all channels. Keep in mind, this signal is never sent to the Main XLR outs. Controls high-impedance microphones or other high-level sources equipped with a 1/4" phone plug. This sets the level to the headphone jack on the rear panel. To avoid damage to your hearing, make sure to turn the dial fully counter-clockwise before using headphones. Slowly turn the knob clockwise until a comfortable listening level is set. This knob sets the overall level for the unit. Make sure the Master level is completely down (full counterclockwise) before powering up the unit. This does not affect the headphone level. With this switch in the OUT position, a unique circuit senses signal conditions that might overload the amplifier and activates compression to reduce gain and avoid clipping. This technique utilizes every watt available for the amplifier to reproduce the signal, yet minimizes clipping and distortion which reduces the potential for speaker damage. Since this function is "invisible" at levels below the clipping point, it is advised that it be activated at all times.
