True to the Music OVERVIEW The KL-8 is a powerful mixing station created with pro keyboard players in mind, with a number of features designed specifically to streamline and enhance any keyboard setup. You can connect up to four keyboards in mono or stereo, each with their own with level controls and LED indicators, along with the ability to bring them in and out of the signal path to keep noisy keyboards muted until they are needed.
3 Radial Engineering Ltd. ON: Activates the input channel. Can be used to keep noisy keyboards out of the signal path until they are needed. INPUTS 1-3: Input channels with individual level control for three mono or stereo keyboards. VU LEDS: Visual indicators to show when signal is present or clipping. PHONES: ¼” TRS headphone outputs with level control. MAIN OUT: Used to set the KL-8 output level to the PA system. ON activates these outputs, MONO sums the left and right channels together.
Radial Engineering Ltd. USB: Redundant USB connections interface with Mac or PC computers for high quality digital audio playback. POWER: Locking connection for external switching power supply. INPUT CH 1-4: Stereo inputs used to connect the analog outputs of your keyboards to the KL-8. AUX SEND/RECEIVE: 1/4” jacks for connecting to an external effects device. INSERT: 1/4” TRS connections allow you to connect a volume pedal or a stereo effects device and have it affect all input channels.
True to the Music 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. Locking XLR power supply included.
True to the Music HEADPHONES AND CUE SWITCHES The headphone outputs and the cue select switches on the KL-8 are designed to allow you to silently monitor your overall mix, or select individual inputs and listen to them without feeding the outputs on stage. This is helpful when testing your connections, checking patch settings on individual keyboards, or adjusting a digital soft synth.
True to the Music AUXILIARY SEND AND RECEIVE The KL-8 is equipped with a stereo AUXILIARY send and return to allow you to share external effects units across all of your connected keyboards. This feature can be used with both mono and stereo effects, as well as with pedals or rackmount equipment. When connecting to mono effects devices, only use the LEFT SEND and RECEIVE connections.
True to the Music DIGITAL CONNECTIONS The KL-8 features two Type-B USB connections, and requires a USB 2.0 cable to connect to your computer or laptop. If using with a Mac, the KL-8 is plug-and-play, with no drivers required. Upon first use, if your audio software does not immediately recognize the KL-8, try restarting your Mac with the KL-8 connected. For users running Windows, please visit www.radialeng.com to download the latest drivers for the KL-8.
True to the Music RECORDING MODE VS. LIVE MODE The KL-8 has two modes, set via the USB ASSIGN switch beside the USB connections on the back of the unit. When this switch is disengaged the KL-8 is set to LIVE mode. This means the USB audio from a connected laptop is treated like any other keyboard input; you can send it to the AUX outputs, blend it with the other keyboard inputs, and control it with an external volume pedal using the stereo insert points.
True to the Music MIDI IN AND OUT The KL-8 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 play back MIDI using a digital audio workstation (DAW) on your computer. The KL-8 doesn’t generate MIDI information on its own, nor can it be controlled via MIDI; it simply transmits the infomation between the 5-pin MIDI and USB connections.
True to the Music LINKING MULTIPLE KL-8 UNITS TOGETHER You can easily expand the KL-8 system using the LINK SEND and RECEIVE jacks, accomodating for larger setups that require more than four keyboards. To link two or more KL-8s, connect a 1/4” TRS cable from the LINK SEND of the first unit to the LINK RECEIVE of the next KL-8. The last KL-8 in the signal chain will act as the master, with all your keyboard signals present at the MAIN and MONITOR outputs.
