Note 1:
If the balanced option is
installed, the transformer wires are
connected. If no option is installed, 3
jumpers per channel are plugged.
Note 2:
Jumper ST6, do not remove
in any case.
Burn–in Period
With the NAGRA PL–L a period of
about 250 ~ 300 hours of use will
allow all components within the
circuits to reach a level of operating
equilibrium. At the end of this period,
the mechanical and sonic
performance of the PL–L will have
had an opportunity to reach its full
performance potential. Serious
audition and permanent installation
options should only be evaluated after
a complete burn–in has occurred.
