楽器からの音声信号が複数のアンプに同時に送り込まれると、ハムノイズや位相の打ち消し合いが発生してしまいます。効果的な唯一の解決方法は、高性能トランスの使用です。通常のトランスですと、ピックアップ信号のような微弱な高インピーダンス信号用には作られていないため、エレキギターやエレキベースの音色自体が変化してしまいます。しかし、Lehle の LTHZ トランスは、そういった高インピーダンス信号用に開発されているため、楽器とアンプの音色を保ちつつ、不快なハムノイズを抑制します。
Symmetrischer Ausgang
Dieses Gerät ist ausgestattet mit einer Standard-TRS-Buchse und liefert bei Bedarf ein symmetrisches Ausgangssignal.
XLR Eingang
LTHZ トランスを搭載しておらずこのマークの付いたすべての Lehle 製品は、金メッキ接点採用のスイッチもしくはリレーによって、信号のみでなくグラウンドも切り替えられます。そのため、複数の異なる出力を交互に切り替える際も、例え 2 台のアンプを同時にオンにせずとも、不快なハムノイズは発生しません。

• Isolator, Reamplification box and problem solver
• Absolutely no signal loss or hum
• Suitable for balanced or unbalanced signals
• Passive – no need for a power supply

The LEHLE P-ISO XLR TRS combines passive isolation with the highest possible signal fidelity.
Its applications range from isolation and eliminating hum, to balancing and reamplification in recording applications along with any signal routing that requires a clean signal free from noise.
At its core is the high-end LEHLE TRANSFORMER HZ, which galvanically isolates the signal, eliminating any possibility of ground loops. The LEHLE TRANSFORMER HZ was specially designed for use with high-impedance signals but also processes low-impedance signals with uncompromising sound quality.
The classic application for the LEHLE P-ISO XLR TRS is as a reamplification box to eliminate hum noise and unbalancing of the signal. Frequently background noise caused by ground loops occurs when two grounded electronic devices are connected to each other.
The LEHLE P-ISO XLR TRS provides a simple, but extremely effective remedy when installed between the two units. By using the isolator, the devices are galvanically isolated and background noise becomes a thing of the past.
Thanks to its ability to use it in both directions and the choice of balanced or unbalanced processing, the LEHLE P-ISO XLR TRS is eminently suitable for many signal types and in numerous situations.
And just in case you are looking for a power connection: the LEHLE P-ISO XLR TRS performs all its functions without any need for a power supply. And due to its optimised size and low weight, it fits easily below your pedalboard or in any pocket.
