Radial Engineering KL-8 Rackmount Keyboard Mixer

Overview

The KL-8 is a powerful mixing station created with keyboard pros 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, with level controls, aux sends, and LED indicators for each. A stereo aux send/receive is available to feed rackmount reverbs and delays and effects pedals, or it can be used as an additional input for a fifth keyboard. MIDI and USB connections make it easy to control a laptop soft-synth, utilizing high quality 24bit/192kHz digital audio converters. The KL-8 also features multiple output options, with transformer-isolated XLR main outputs to feed the PA, monitor outputs for a set of speakers on stage, and dual headphone output for local monitoring and testing.

Features:

- Four stereo analog inputs for keyboards
- Redundant USB connections for laptop soft-synths
- Stereo Aux Send/Receive with optional footswitch control
- Headphone outputs and cue switches for silent monitoring
- Link multiple KL-8s for larger setups

Redundant USB Inputs
When you can't afford to have a break in the performance due to laptop failure, the KL-8 allows you to set up redundant laptop systems and seamlessly transition from one to another. A secondary USB input on the KL-8 allows you to keep your backup laptop at the ready - when failure occurs simply hit the USB select switch on the front panel or use the optional JR-1L remote footswitch to instantly switch to the backup… read more system.

Silent Cueing and Monitoring via Headphones
A built in headphone amp and dual 1/4" TRS outputs give you the option to practice and record silently, or cue up individual inputs on stage without feeding signal out to the audience over the PA system. Each input channel on the KL-8 is accompanied by a Cue switch that will remove that input from the main and monitor outputs and reroute it directly to the headphones, so you can easily adjust patch settings and test playback over USB without affecting the performance.
