Palmer Wipper Passive DI Box – Rugged Direct Injection Solution

Description

If you need to pick up the pure sound of your guitar, bass or keyboard, you need a high-quality DI box which does not alter the natural sound or add any noise.
The Palmer wipper is a single channel passive DI box with a high-quality transformer, which also handles high levels without distorting or losing the pure sound of your instrument. With a ratio of 10:1, it can be used for optimal impedance and level adjustment to connect instrument signals from guitars, bass, keyboards or synthesisers to a balanced microphone input. At the same time galvanic isolation prevents ground loop hum, so that the signal remains pure, clear and ultra-low noise, without any interference. Thanks to a switchable 30 dB pre-attenuation, the wipper can also be looped in between amplifier output and the loudspeaker.
The Palmer wipper is an easy-to-use problem solver. Its passive construction means it does not need any batteries or a phantom power. This makes it extremely fail-safe and also virtually indestructible thanks to its aluminum and steel casing. With its ability to retain the natural sound of your instrument, it also cuts a fine figure studio and live environments. This way you can simply be true to your sound.
