Palmer wipper Passive DI Box
If you need to pick up the pure sound of your guitar, bassor keyboard, you need a high-quality DI-Box which does not alter the naturalsound or add any noise.
The Palmer wipper is a single channel passive DI box with ahigh-quality transformer, which also handles high levels without distorting orlosing the pure sound of your instrument. With a ratio of 10:1, it can be usedfor optimal impedance and level adjustment to connect instrument signals fromguitars, bass, keyboards or synthesizers to a balanced microphone input. At thesame time galvanic isolation prevents ground loop hum, so that the signalremains pure, clear and ultra-low noise, without any interference. Thanks to aswitchable 30 dB pre-attenuation, the wipper can also be looped in betweenamplifier output and the loudspeaker.
The Palmer wipper is an easy-to-use problem solver. Itspassive construction means it does not need any batteries or a phantom power.This makes it extremely fail-safe and also virtually indestructible thanks toits aluminum and steel casing. With its ability to retain the natural sound ofyour instrument, it also cuts a fine figure studio and live environments. Thisway you can simply be true to your sound.
