Palmer RIVER wupper Passive Line Isolation Box

About: Palmer RIVER wupper Passive Line Isolation Box

The more complex the setup, the higher the likelihood of ground loops. The Palmer wupper Line Isolation Box restores peace and quiet, so you can enjoy your sound. No hum or crackling.

• Line isolation for guitar/bass/keyboard, also suitable for hi-fi and car hi-fi.
• Single channel: Jack input and jack output
• Reliably eliminates ground loops and interference signals.
• Galvanic isolation by transformer
• Can also be used to balance signals.
• Unadulterated sound
• Passive operation: simple and reliable
• Sound pressure level resistant up to +6 dBu
• Robust housing made of aluminum and sheet steel
• Includes a rewritable tour label for attachment to the back of the Wupper.
• Engineered in Germany

The Palmer Wupper is an isolation transformer in a robust housing made of aluminum and steel. It separates the ground potentials of two devices, thus preventing equalizing currents and ensuring that only your sound is transmitted – cleanly and without interference.

The Palmer Wupper was developed for guitar and bass applications; however, its brilliant, unadulterated sound is equally suitable for keyboards and hi-fi equipment. The inputs and outputs with jack connectors can be used for balanced or unbalanced connections. This allows the Palmer Wupper to also be used to balance unbalanced signals, enabling longer cable runs without any loss of sound quality. Due to its passive design, the Wupper requires neither batteries nor phantom power, making it extremely reliable.

The Palmer Wupper is a simple, efficient hum killer: You connect it between two devices, and the interference disappears. Sometimes it really can be that easy!

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.
