The Gold Digger 4-Channel Mic Selector from Radial Engineering enables you to quickly compare the sound of 4 different microphones while sharing the same preamp. A straight wire passive circuit design is void of any audio buffers or transformers. This unit uses military-grade gold contact relays to manage the switching process, thus ensuring the mic signal is maintained without introducing color, distortion, or artifacts of any kind.

The Gold Digger features 4 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 48V 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 helps to improve the workflow, but it gives the artist more confidence with the sound of the vocal, resulting in a better overall performance.
