- Balancing and impedance matching for guitar, bass, keyboards & synthesizers
- Eliminates ground loop hum thanks to galvanic transformer isolation
- Extremely fail-safe, no power supply required
- THRU-output for passing the input signal to the amplifier
- THRU-output jack can also be used as second input to sum two input signals
- Pure and unaltered low-noise audio
- Handles even high-level inputs without distortion
- Switchable 30 dB pad for extremely high input levels (e.g. amplifier output)
- Solid casing made of aluminium and steel
- Incl. rewritable tour label for attachment onto the back of the wipper
- Engineered in Germany
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.
