Palmer RIVER kyll Passive 2-Channel Line Isolation Box

About: Palmer RIVER kyll Passive 2-Channel Line Isolation Box

Consumer devices, as well as many professional keyboards such as synthesizers and digital pianos, and some small mixing consoles, have unbalanced outputs. To connect them to a sound system and to bridge longer cable runs without interference, balanced signal transmission is necessary. The Palmer Kyll performs the required signal balancing.

• For connecting devices with unbalanced or balanced outputs to sound reinforcement systems
• Reliably eliminates ground loops and interference signals.
• Galvanic isolation by transformer
• Dual channel for stereo or two independent signals
• Inputs as combo jacks, usable with XLR or jack plugs
• 2 balanced XLR outputs
• Sound pressure resistant up to +20 dBu
• No power supply required
• Robust housing made of aluminum and sheet steel
• Includes a rewritable tour label for attachment to the back of the Kyll
• Engineered in Germany

Thanks to galvanic isolation via a transformer, the kyll simultaneously eliminates ground loops; a ground lift switch is also integrated. This benefits devices that already have balanced outputs, as these can also be susceptible to interference. The Palmer kyll reliably eliminates hum and crackling.

The Palmer kyll is extremely robust. Compared to typical line isolators for media applications, it can handle significantly higher input signals without any audible distortion: up to +20 dBu! The kyll can also process quieter signals without any loss of sound or noise, thanks to its purely passive design with generously sized isolation transformers. This makes the Palmer kyll extremely easy to use and highly reliable, as it requires neither batteries nor phantom power. Conveniently, the inputs are combo jacks that accept either TRS or XLR connectors. No adapters needed! The balanced outputs are professional XLR connectors.

The kyll line isolation box is a universal solution for eliminating ground loops. When connecting unbalanced equipment, the signal is simultaneously balanced. Whether at home, during lectures, in the rehearsal room, on stage, in nightclubs, or at large events, the Palmer kyll ensures clean, noise-free sound everywhere.

Tough and Durable New Design

We know that the demands of stage and studio require equipment that is not only high performing, but also rugged and durable. The River Series represents a new design philosophy that combines form and function to create audio tools that are as rugged as they are stunning. These units are built to last, with rugged metal chassis and reinforced connectors. We've tested them in the harshest conditions, so you can count on the River Series to deliver, gig after gig, session after session, year after year.

Rewritable Tour Labels

In the world of professional audio, organisation is king. Misplaced or incorrectly connected equipment can turn a flawless performance into an unforgettable disaster. That's why the River Series introduces an innovative feature: rewritable tour labels. These color coded handy labels let you customize your di-boxes, line isolators splitters & mergers, ensuring each piece is in the right place, every time whether in the busy backstage area of a rock concert or the tangled web of cables in a recording studio.
