PAM-3

The Krell PAM-3 Preamplifier is a result if two years of
research. Research not only in electronics, but also in
marketing. Krell has developed sophisticated audio circuitry
that meets our own rigid electrical standard and above all
sounds musical. The PAM-3 is so advanced that it will make a
statement for years to come. This instruction manual is
intended to enhance the usage and enjoyment of your PAM-3.

UNPACKING

While unpacking your PAM-3, please inspect the unit carefully
for shipping damage. If all is well, proceed. Position

PAM-3 in your system. Plug in the power supply connectors

on the back of your preamp, linig up the red dots of the
connectors with recepticals on the rear panel and push

gently until it snaps into place. Next plug in power supplies
into the A.C. wall outlet. The green leds on the preamp and
the two power supplies should light up. If they do not, stop
and contact your dealeer or the factory.

HOOK UP

Your PAM-3 comes to you factory set for moving coil operation
with an impedance of 100 ohms. This impedance can be changed
by adjusting switches marked S 1 and S 3. To do so remove
the cover of the preamp with the supplied allen key and refer
to figure 1 and the following table.

TABLE OF MOVING COIL ADJUSTMENTS

all switches in the open position = 47,000 ohms
all switches open except switch 8 on = 1,000 ohms
all switches open except switch 7 on = 800 ohms
all switches open except switch 6 on = 470 ohms
all switches open except switch 5 on = 250 ohms
all switches open except switch 4 on = 100 ohms
all switches open except switch 3 on = 47 ohms
all switches open except switch 2 on = 25 ohms
all switches open except switch 1 on = 5 ohms

To change moving coil to rixed coil (moving magnet),

adjust S 2; refer to switch direction in figure 1.

S 2 switch levers should point to the right side fer moving
coil and to the left for moving magnet.
