Radial Gold Digger Studio Microphone Selector and Switcher

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.

Gold Digger Applications

Comparing Four Studio Condenser Mics

The Gold Digger lets you quickly compare the sound of four microphones and send the signal to the same preamp. This assures an 'honest' comparison as all mic signals employ the same audio path. Separate 48V on-off switches let you activate phantom as needed.

Comparing Various Direct Boxes

Comparing DI boxes can often lead to surprising results. Often, one will use an active DI like the J48 only to find that a passive one like the JDI could in some instances sound better. Plug in the four DIs just like you would a microphone and you are set to go.

Selecting a wireless system

The Gold Digger can also be used in live touring where you may want to direct as many as four different wireless systems to a single audio input channel in the PA system. This could be 4 mics in a house of worship, 4 wireless guitars, or maybe a couple of mics in a town-hall meeting.
