Both preamplifiers have innovative operational features. The KBL has two
balanced inputs and one set of balanced outputs in addition to four single-
ended inputs and one set of single-ended outputs. This allows one KBL to
accommodate balanced line sources and amplifiers, which Krell believes to
be the standard for high-end audio gear. Therefore, it is only necessary to
purchase a second KBL to achieve dual-mono, fully balanced operation.
The KBL input labeling is a departure from the norm as well. Instead of
the conventional "phono, tuner, tape, aux, etc." we have labeled the inputs
B-l, B-2, S-l, S-2, S-3, S-4. These refer to Balanced Input #1, Balanced Input
#2, Single-ended Input #1, etc. Components in audio systems today are
unpredictable. This input labeling allows KBL Selector can to be set-up or
changed by each user to create the order he desires.
The KBL has front panel adjustments for output gain and absolute phase.
The Gain switch provides a course adjustment to compensate for systems of
different efficiencies and for level differences in source components.
The KPA has inputs for two different cartridges. There is a front panel
switch to adjust between the gains required for moving coil and moving
magnet cartridges. Adjustment for cartridge impedance loading is on the
front panel as well. Perhaps the most interesting features on the KPA are
the front panel adjustments for high and low RIAA trim. These allow you
to tailor the RIAA equalization to specific records in small increments.
Single-ended/Balanced switching are also on the front panel.
