PAM-5

The Krell PAM-5 Preamplifier is a result of four years of research.
Research not only in electronics, but also in marketing. Krell

has developed sophisticated audio circuitry that meets our own
rigid electrical standards and above all sounds musical. The PAM-5
is so advanced that it will make a statement for years to come.
This instruction manual is intended to enhance the usage and en-
joyment of your PAM-5.

UNPACKING

While unpacking your PAM-5, please inspect the unit carefully for
shipping damage. If all is well, proceed. Position PAM-5 in your
system. Plug in the power supply connectors on the back of your
preamp, lining up the red dots of the connectors with recepticals
on the rear panel and push gently until it snaps into place. Next
plug power supplies into the A.C. wall outlet. The green led on
the preamp and the red leds on the power supplies should light up.
If they do not, stop and contact your dealer or the factory.

HOOK UP

Your PAM-5 comes to you factory set for moving coil operation with
an impedance of 100 ohms. This impedance can be changed by adjust-
ing switches marked S l 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.
