Consumer devices, along with many professional keyboards such as synthesizers, digital pianos, and some small mixers, have unbalanced outputs. To connect them to a professional sound system and prevent noise interference over long cable runs, balanced signal routing is essential. The Palmer Kyll is designed for this task, ensuring necessary signal balancing.

The Kyll also provides galvanic isolation through a transformer, eliminating ground loops. Simply activating the ground lift switch achieves this. Even devices with balanced outputs can benefit, as they are not immune to noise. The Palmer Kyll effectively removes hums and buzzes.

Capable of handling very high levels, the Palmer Kyll can process significantly "hotter" input signals than typical line isolators used in media applications, up to +20 dBu, without audible distortion. It can also handle quieter signals without altering the sound or introducing noise, thanks to its passive operation with large isolating transformers. This makes the Kyll exceptionally user-friendly and reliable, requiring no batteries or phantom power. The inputs are combo sockets, accommodating both jack and XLR connectors, making adapters redundant. The balanced outputs are professional XLR sockets.

As a universal solution for eliminating humming ground loops, the Kyll line isolation box also balances the signal when connecting unbalanced equipment. It ensures a clean, noise-free sound whether used at home, during lectures, in rehearsal spaces, on stage, in clubs, or at large events.
