cable. Connect one end of the linking cable to the connector labeled Out on
the back panel.
3. Connect the other end of the linking cable to the In port on the second
amplifier.
4. To couple three amplifiers, connect a second linking cable to the Out
connector on the second amplifier. Connect the remaining end to the In port
on the third amplifier.
5. Connect additional amplifiers as described in step 4.
6. Point a KRELL remote control at the control amplifier and press the Amp.
Power button. The amplifiers will all power up at the same time.
Notes:
When configured for Remote In / Out operation, each amplifier can be turned
ON/OFF individually from their respective front panels. All amplifiers must be
returned to the identical power state manually in order to maintain remote
synchronization.
The communication cables are standard five pin DIN ~;ables and are commonly
referred to as MIDI cables. Contact your KRELL dealer or KRELL Industries to
obtain remote link cables.
For Use with a Tube Preamplifer
The Full Power Balanced amplifiers feature direct coupted circuitryfrom input to
output. This topology eliminates all coupling capacitorsfrom the audio signal
path. Coupling capacitors are used to blockdamaging direct current (DG) but
have sonic characteristics that impact music negatively. Instead, KRELL uses
non-obtrusive DC servos that strip DC from the signal without corrupting the
music.
Tube preamplifiers, by design, are capacitively coupled. For this reason, the
benefits of a direct coupled amplifier cannot be realized when used with a tube
preamplifier. Additionally, many tube preamplifiers output a great deal of DC.
This DC may exceed the servos of a Full Power Balanced amplifier. Excessive
DC level in a signal can damage amplifiers, speakers, or both.
To combat this potential problem, the Full Power Balanced amplifiers include
internal jumpers that insert coupling capacitors into the signal path. These
capacitors should be engaged when using a tube preamplifier with a Full
