MAKING CONNECTIONS

Before making audio connections, always ensure volumes levels are turned down or off. This
prevents turn-on transients which could harm more sensitive components such as tweeters.
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 traffi c area, you may
want to use the power supply cable clamp for an extra secure power connection.
With the power connected, follow these steps to set up the Gold Digger controls. First, make
sure each of the four Gold Digger mic inputs has the +48V phantom power switch in the off
position (outward, LEDs off). Also turn off the phantom power feature on your mic preamp.
For best results, the Gold Digger should be the only source of phantom power. Next, set the
four TRIM controls to maximum (fully clockwise). Use a guitar pick or small screw driver to
make adjusting the TRIM controls easy.
Take a moment to notice how the mic input ON buttons work. When pressed, the switch will
simultaneously turn-on the mic input while also turning-off whatever mic is currently active.
This switching method allows only one mic signal to pass through the Gold Digger at a time.
Connect your microphones to the Gold Digger mic inputs using standard XLR cables.
Determine if +48V phantom power is needed depending on the type of microphone. Most
condenser microphones can be powered by the Gold Digger's onboard phantom power.
Dynamic or ribbon mics do not need it and phantom can be left off for those mic inputs.
Simply use a small screw driver to access the recessed +48V switch if phantom is needed.
An illuminated LED indicated the phantom power is active for that mic input.
Connect the Gold Digger's male XLR output to your preamp or mixer and use a low gain
setting for testing. Select input-1 (LED will illuminate) and monitor the mic signal as you
slowly turn up the volume on your audio system. It is always best to test all four mics at low
volumes as this reduces opportunity for feedback or noise due to bad cables or improper
connections. Move on and repeat the signal check process for the rest of the mics connected
to the Gold Digger inputs. Once all four mics are tested and working you can set the front
panel TRIM controls to balance the outputs of the microphones.
