The preamplifier of the KRELL of the 3rd work
developed as a stereo preamplifier of No. 1 which can control the thought of the
tone-quality investigation by the simple design put into practice by PAM-2 or
KRS-1 in one volume as it is.
While reviewing the state of the signal
path in a stereo machine, careful selection of the using element and part which
can be said also as the extreme has completed the in-use cage and the quality
Moreover, the power-source part carried out the separation to
the main unit like PAM-2, and has adopted the form of a right-and-left
The tape-out selector and the balancer of a 1dB step in
which dubbing between two tapeses is also possible, and MC amplifier which can
use MC cartridge direct are carried.
A phone input is changed to man month
and MC with the switchpoint on a substrate, and also nine steps of
correspondences are possible for it to 5ohm-1kohm to MC.
In order to
realize high-definition compact-disk input, the scheme which divides with other
high-level inputs and is received with exclusive buffer amplifier is adopted.
Furthermore, the special phase compensator is carried in PAM-3.
the influence of the filter inside a CD player, is what noted that the phase
between frequencies in an audio frequency band was disturbed, and has rectified
the phase of the compact disk player connected by changing eight switchpoints
per channel which it had on the substrate.
