Gold Digger™ Using & Applications

The following page discusses how to use the Gold Digger. As you will soon realize, it is very easy to use.


The Gold Digger is a 4 input, 1 output mic selector that has been designed to provide an honest comparison between four microphones to find the most suitable one for a given artist. This process involves the artist right from the beginning which usually results in a more comfortable and confident recording. This improves workflow for the studio. Mic selection is done using front panel 'radio-style' switches that activate the desired mic and automatically turn off the others to eliminate bleed and crosstalk.

Making connections

Before making audio connections, always make sure volume levels are turned down or off. This helps eliminate turn-on transients which could harm more sensitive components such as tweeters from being damaged. There is no power switch on the Gold Digger. As soon as you connect the power supply, it will turn on. If you are using the Gold Digger in a mobile studio or in a high traffic area, you may want to use the power supply cable clamp as extra security.

To start, make sure all of the 48V phantom power switches are in the off position (out) – LEDs off and set the TRIM controls fully clockwise (max) so that there is no attenuation on any of the mic inputs. Connect your microphones to the Gold Digger using standard XLR cables. Depending on what type of microphone you have will determine if phantom power is needed. Most condenser microphone employ phantom. Dynamic mics or ribbon mics do not. Simply push in the 48V switch if needed.

Connect the male XLR out to your preamp. Select channel-1 on the Gold Digger. Talk into the mic as you turn up the volume on your preamp and recording system. It is always best to test at low volumes as this reduces opportunity for feedback or damage due to bad cables or improper connections. Once you have this working, switch to channel-2 and repeat. Once all 4 mics are tested and working, locate the mic with the lowest output level. Using a tweaker or small screwdriver, match each of the other three mics so that the relative output is the same. This will ensure a fair and honest evaluation. Once all of the mic levels have been matched, you are now set to test and record.

Try comparing mics on vocals, guitars, snare drum, kick drum… you can sometimes be surprised at how well one mic may work in a given situation and how the same mic may not in another. You can also compare direct boxes following the same procedure. You would be surprised at how different each DI can sound. In fact you may be surprised to find that just like microphones DIs all have different personalities that can truly flatter certain instruments or render them listless… Have fun.

For even more fun, try a Radial Cherry Picker! This lets you compare various preamps to find the best one for a given vocal. Using the Gold Digger with a Cherry Picker lets you find the best mic-preamp combination.
