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.
