Palmer kyll Passive 2-Channel Line Isolation Box

Palmer kyll Passive 2-Channel Line Isolation Box

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

Due to the galvanic isolation viaa transformer, the kyll also eliminates ground loops. To do this, simply engagethe ground lift switch. Devices that already have balanced outputs also benefitfrom this, since noise can occur even here. The Palmer kyll reliably eliminateshum and buzz.

The Palmer kyll is capable of veryhigh levels. Compared to conventional line isolators for media applications, itcan process much “hotter” input signals without unwanted distortionbeing audible: up to + 20 dBu! But the kyll can also process quieter signalswithout causing any sound alteration or noise, because it works purelypassively with large isolating transformers. This makes the Palmer kyllextremely easy to use and fail-safe, as it requires neither batteries norphantom power. Conveniently, the inputs are designed as combo sockets thataccept jack or XLR connectors. Adapters are unnecessary! The balanced outputsare designed as professional XLR sockets.

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