GOLD DIGGER

™

OUTPUT SELECTOR

The Gold Digger is a ‘solid wire’ passive mic selector that enables the studio engineer to compare
the sound of four microphones using the same preamp. This allows the artist to ‘hear herself’
before they record in order to fi nd the most suitable setup to suit her particular voice. Four ‘radio
style’ selector switches ensure only one microphone is active at any one time. 48V phantom
power is generated by the Gold Digger to ensure stable noise-free mic selection. There are no
buffering amplifi ers in between the mic inputs and the output, thus ensuring the signal is 100%
pure and completely free of any form of distortion or coloration. Optimizing the microphone
to best suit the artist not only assures a better sounding track, the fact is: when the artist is
more comfortable with the sound, this usually results in a better performance. This results in a
smoother and more productive work fl ow.

Features

• Four selectable inputs with trim adjusts

• Pure ‘straight wire’ passive signal path

• Gold contact sealed relays do the switching

• Internally generated 48V phantom power

Applications

• Used to compare four microphones

• Increases artist’s confi dence when recording

• Can be used to compare four direct boxes

• May also be used as a 4x1 line level selector

Cool factors

• Super quick and effi cient means to get best audio

• Signifi cantly improves workfl ow in the studio

• Does not introduce color to the signal path

• Helps improve the vocal performance & sound

CHANNEL ON: Radio style push button
mic selection for fast comparison
between microphones.

TRIM ADJUST: Individual trim controls let
you quickly match signal levels between
mics for an honest comparison.

CABLE CLAMP: Locking cable
clamp secures the power cable to
the Gold Digger to prevent acciden­tal disconnection.

RECESSED PANEL: Book end design
creates a protective zone around the
switches and controls.

+48V PHANTOM - recessed on-off switch
lets you activate phantom power for each
input individually.

XLR CONNECTORS: Female XLR
inputs are used to connect microphones.
The male XLR output connects to a
mic-preamp.

COMPARING FOUR STUDIO 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.

15VDC: Like professional mixers,
the power supply is taken out of the
box to reduce noise and ensure the
most transparent signal fl ow.

14-GAUGE STEEL: Heavy-duty construc­tion eliminates stress on the PCB and pro­vides excellent shielding against magnetic
fi elds and RF which could introduce noise.

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 fi nd 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.

PAD: Full bottom no-slip neoprene
foam pad provides electrical insu­lation and mechanical isolation for
plenty of stay-put-ness.

SWITCH WIRELESS MICS ON STAGE

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.
