Radial Engineering Ltd. is pleased to announce that the KL-8, a rackmount professional keyboard mixer and digital interface, is now shipping.

Put yourself in control of the mix

The KL-8 is a unique mixing station created with keyboard pros in mind, including a number of features designed specifically to streamline and enhance any keyboard setup. You can connect up to four keyboards in mono or stereo, with level controls, aux sends, and signal/clip LED indicators for each. A stereo aux send/receive channel is available to feed rackmount reverbs, delays, and effects pedals, or it can be used as an additional input for a fifth keyboard.


The KL-8 is a rackmount keyboard mixing station designed to provide complete control over a professional keyboard setup, both on-stage and in the recording studio.

Redundant USB inputs

The KL-8 is also a powerful digital interface with high quality 24bit/192kHz digital audio converters, utilizing MIDI and USB connections that make it easy to control a laptop soft-synth. Redundant USB connections mean that you can have a backup laptop plugged in and ready to go should your primary source fail; this is especially helpful for keyboard players who are also controlling playback for backing tracks during their performance. An optional JR1-L remote footswitch can be employed to switch between the USB inputs at a moment’s notice.

Silent cueing and monitoring via headphones

The output section includes two sets of transformer-isolated outputs to feed the PA system and a pair of powered monitors, with individual level controls and mono sum switches to accommodate for limited channel availability. Dual 1/4″ headphone outputs are also included for local monitoring and testing. A cue system allows any keyboard input to be muted from the overall mix and fed directly to the headphones to silently check patch settings without feeding signal to the audience.

Equally well-suited for a live stage or a professional recording studio, multiple KL-8s can be linked to accommodate even larger keyboard setups. Like all Radial products, the KL-8 is built in Canada and features a transferable 3-year warranty.
