Radial Gold Digger

Studio Microphone Selector and Switcher


About this item



The Radial Gold Digger is a 4-input, 1-output switcher that allows you to seamlessly audition multiple microphones through a single preamp, improving studio efficiency and workflow without altering the tone of each microphone or requiring downtime to re-patch any cables.

  • Audition different microphones with the press of a button
  • Four selectable inputs with trim controls
  • Straight-wire distortion-free signal path
  • Saves time and improves workflow in the studio

Choose the right mic every time

The Gold Digger allows you to record with confidence knowing that you’ve selected the right tool for the job each and every time you record. It provides the ability to instantly A/B between up to four microphones, without introducing any coloration, noise, or distortion. Individual set & forget trim controls let you adjust each mic level so that they produce the same relative output, and 48V phantom is available to power condenser microphones. The Gold Digger makes it easy to audition multiple options while maintaining studio efficiency and ensuring a smooth workflow. When paired with the Radial Cherry Picker™ you can choose between four microphones and four preamps in any combination, giving you the freedom to explore endless sonic possibilities.

The Gold Digger is a switching device that is void any form of buffering while employing the absolute minimum number of passive components in the audio signal path. The result is an exceptionally linear performance at all frequencies, phase and distortion measurements that are below our test equipment capabilities and a resulting signal-to-noise that exceeds 140dB. This confirms the claimed ‘straight wire’ performance and gives complete assurance that the Gold Digger will not add not color, distortion or introduce artifact into the signal path.
