Product Highlights

Product Description

Enabling audio engineers to quickly compare the sound of four different microphones through the same preamp, the Radial Gold Digger Passive Microphone Selector uses a 'straight wire' passive circuit design without signal reducing audio buffers or transformers. The Gold Digger employs military grade gold contact relays to manage the switching process, thus ensuring the pristine mic signal without unwanted color, distortion or artifacting.

Radial Gold Digger Passive Microphone Selector Features
  • Four selectable inputs with trim adjusts
  • Straight wire distortion-free signal path
  • Will not introduce color or artifact
  • Increases artist's confidence when recording
Features include four rear-mounted XLR-F mic inputs plus an XLR-m output to feed the preamp. To eliminate bleed between microphones, each channel is equipped with a 'radio style' selector switch that ensures only one mic is on at a time.

The external supply provides power for the LED indicators, charges the relays and enables the Gold Digger to generate 48 volt phantom which can be turned on or off for each mic as needed. To ensure an 'honest' comparison between microphones, individual 'set & forget' trim controls let you adjust each mic level so that they produce the same relative output.

Once set up, the Gold Digger not only improves workflow, but also gives the artist more confidence with the sound of the vocal, resulting in a better overall performance.
