Palmer wipper Single-Channel Passive DI Box

Developed for professional applications in the fields of studio recording, stage performance, TV/broadcast, and live event, the Palmer wipper is a single-channel DI box used to preserve audio quality when connecting the unbalanced output of an instrument to the balanced input of a mixing desk or PA. Featuring a passive design that requires no battery or phantom power, the wipper is particularly well suited for active instruments, often recognizable in that they have a battery compartment (such as active electric/acoustic guitars, electric guitars, and electric basses) or are mains-powered (such as a keyboard). It can also be used to connect speaker outputs from guitar amplifiers to balanced mixer inputs or audio interfaces.
