OPERATING UP THE PH3
2.1
REAR PANEL CONTROLS
POWER ON
When first powered on, the preamp will become operative only after approximately two
minutes of warm up. This ensures proper stabilization of the circuitry and avoids any
unwanted noise. After this delay, the output of the preamplifier is connected to the output
connectors.
Note: The GOLDMUND PH3 phono preamplifier should remain connected at all times.
If the power cord is accidentally disconnected, a special safety circuit switches the preamp
to muting, to avoid any disturbance to reach the power amplifier and the speakers, even in
case of a power failure in the building.
It is normal for a slight sound to be heard from the speakers when the Phono Preamplifier is
turned ON or OFF. The PH3 is self-protected and the sound heard is corresponding to the
charging and discharging of the capacitors.
INPUT MM/MC SELECTOR
This front panel switch controls which input is used: the Moving Magnet or the Moving Coil
input.
GAIN
Level adjustment acting simultaneously on both channels for both the moving coil and the
moving magnet sources.
