Description

The Gold Digger is a 4-channel mic selector that enables the engineer to quickly compare the sound of four different microphones while sharing the same preamp. A 'straight wire' passive circuit design is void of any audio buffers or transformers. Instead, the Gold Digger employs military grade gold contact relays to manage the switching process, thus ensuring the pristine mic signal is maintained without introducing color, distortion or artefact of any kind.

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.

The Gold Digger - A tool designed to get the very best out of each and every performance.
