Consumer devices, as well as many professional keyboards such as synthesisers and digital pianos as well as some small mixers have unbalanced outputs. In order to connect them to a professional sound system and to avoid interfering noise over long cable runs, balanced signal routing is needed. For this purpose, the Palmer kyll handles the necessary signal balancing.

Due to the galvanic isolation via a transformer, the kyll also eliminates ground loops. To do this, simply engage the ground lift switch. Devices that already have balanced outputs also benefit from this, since noise can occur even here. The Palmer kyll reliably eliminates hum and buzz.

The Palmer kyll is capable of very high levels. Compared to conventional line isolators for media applications, it can process much "hotter" input signals without unwanted distortion being audible: up to + 20 dBu! But the kyll can also process quieter signals without causing any sound alteration or noise, because it works purely passively with large isolating transformers. This makes the Palmer kyll extremely easy to use and fail-safe, as it requires neither batteries nor phantom power. Conveniently, the inputs are designed as combo sockets that accept jack or XLR connectors. Adapters are unnecessary! The balanced outputs are designed as professional XLR sockets.

The kyll line isolation box is a universal problem solver for eliminating humming ground loops. When connecting unbalanced equipment, the signal is simultaneously balanced. Whether at home, at lectures, in the rehearsal room, on stage, in clubs or at large events, the Palmer kyll ensures a clean sound without noise.

High quality, wish it was just a little smaller
Style: Squeaker, Size: Small (2 Pack)
Love these. My dogs would play ball all day if I let them. These are very durable and bouncy. Love that it’s washable. They would chew up the small “tennis” balls to pieces so I love that they can’t destroy these. My only criticism is I wish these were just a little smaller (like the size of the small Kong tennis balls). My dogs can carry it in their tiny mouths but they can’t get their mouth around it enough to chew it to get the squeaker to squeak, which is their favorite thing.

My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball. A great entertainment value. This ball does not squeak.
