14 Krell Full Power Balanced X Series Power Amplifiers
4. Connect the other end of the MIDI cable to
the Krell Link in connector on the next com-
ponent.
To link another component, connect a sec-
ond MIDI cable to the Krell Link out con-
nector on the back panel of the second
component. Connect the remaining end of
the MIDI cable to the Krell Link in connec-
tor on the back panel of a third component.
5. Link additional components, if desired, as
described in Steps 3 and 4.
The components are now ready for operation with
Krell Link.
DC PROTECTION CIRCUITRY
Full Power Balanced amplifiers use unobtrusive
direct current (DC) protection circuitry that
strips DC from the signal without corrupting
sound reproduction. Full Power Balanced
amplifiers feature direct coupled circuitry from
input to output. This topology eliminates all cou-
pling capacitors from the audio signal path.
Coupling capacitors block damaging DC but
have sonic characteristics that corrupt sound
reproduction.
Note
For more information about DC protection cir-
cuitry features, see Amplifier Troubleshooting,
on page 17.
USING A TUBE PREAMPLIFIER
The high DC output of tube preamplifiers may
exceed the DC protection circuitry of Full
Power Balanced amplifiers. Excessive DC
level in a signal can damage amplifiers, speak-
ers, or both. The coupling capacitors in Full
Power Balanced amplifiers must be engaged
when using a tube preamplifier. An authorized
Krell dealer, distributor, or Krell must activate
these capacitors.
Coupling capacitors must be inserted into the
signal path by your authorized Krell dealer, dis-
tributor, or Krell before you can use your Full
Power Balanced amplifier with a tube preampli-
fier.
IMPORTANT
Please read the Warranty, on page 20, to
understand the warranty limitations of Full
Power Balanced amplifiers when used with
tube preamplifiers.
