The Essentials to Know About the WIPPER Passive DI Box
- Passive DI with impedance matching for guitars, basses, keyboards, and synthesizers, ideal for feeding a console or stagebox with a clean signal.
- Galvanic isolation via transformer to effectively eliminate hum caused by ground loops without degrading the sound.
- Handling of high levels without distortion, with a switchable -30 dB attenuator for very powerful sources (e.g., amplifier output).
- Convenient THRU output to send the signal to an amp, also usable as a second input to combine two sources.

A Passive DI Designed to Secure Audio Connections
On stage as well as in the studio, a direct box is often the simplest solution to secure a connection between an instrument and a sound reinforcement or recording system. The WIPPER fits this logic: a compact, robust, and immediate tool aimed at preserving your instrument's character while making the signal more manageable in demanding audio environments (long cable runs, multicore cables, lighting, backline power supplies, etc.). Its passive design avoids any power requirements and favors quick setup, particularly appreciated in live situations.
Who and When to Use the WIPPER?
The WIPPER is intended for guitarists and bassists who want a more stable output to the console while keeping their amp on stage via the THRU, but also for keyboardists and synthesizer users seeking a clean and silent front-of-house signal. It is also suitable for sound engineers and home studio users facing ground noise, hum, or setups where multiple devices share different power supplies. If you have ever heard a buzz as soon as you connect an instrument to an interface or console, the galvanic isolation of the transformer is typically the right solution.

Questions frequently asked
Does the Palmer WIPPER eliminate ground loop hum?
The galvanic isolation provided by the transformer breaks ground loops that cause hum. This design is suitable for setups with power strips or devices powered from different electrical networks.
Can the amplifier stay connected with this passive DI?
The THRU output sends the input signal to an amplifier while the DI feeds the PA system. The THRU jack can also receive a second source to combine two input signals.
Does the WIPPER accept a powerful amplifier output?
A switchable -30 dB attenuator allows handling extremely high input levels, including those from an amplifier output.
Does the Palmer WIPPER require power?
No power supply is needed, as this direct box operates passively. This makes it suitable for quick live setups.
Is the WIPPER DI robust enough for stage use?
The enclosure combines aluminum and steel to withstand transport and heavy use. A rewritable label on the back facilitates identification in a case or on stage. This unit is not rack-mountable.
