GoldMike MK2
9
Outputs 1/2
The preamplifier signals are fed to these electronically balanced
outputs. Alternatively the GoldMike MK2 can be equipped with
optionally available transformer outputs from Lundahl (see
“Lundahl Transformers” on page 22).
Since the XLR and 1/4 inch TRS connectors are wired in parallel,
an unbalanced connection at one connector will cause unbal-
anced operation in its parallel connector, e.g. if a mono 1/4 inch
plug is inserted into the 1/4 inch jack, the corresponding XLR
socket will also operate unbalanced.
GND Lift
The GND Lift switch separates internal ground from chassis
ground. The switch can be activated to eliminate ground loop
humming which may occur if the GoldMike MK2 is connected to
units with a different ground potential.
The switch should normally be in the GND position to main-
tain the shielding effect of the metal housing for internal
GoldMike MK2 electronics.
Instr. Input 1/2
The Instrument input jack is placed on the front panel for easy
access. It should be used to connect instruments like E-bass,
electric guitars, acoustic guitars with pick-ups etc.
The Instrument input features a 1 MOhm (one Mega Ohm) input
impedance.
IMPORTANT: As long as an instrument is plugged into front
Instrument input, the rear panel Line Input is deactivated.
