Krell Full Power Balanced X Series Power Amplifiers
Krell Trigger remote out/in connectors (17) on the back panel of the
Full Power Balanced amplifier (labeled
KRELL LINK
) allow you to syn-
chronize remote control operation for systems that include multiple
amplifiers and associated components. When the Krell Trigger
remote out/in connectors are used, the remote capabilities of the
linked components are controlled from one amplifier or preamplifier,
called the control component. The linked components respond to
stand-by and operational mode commands from the control compo-
nent via MIDI cables.
Krell Trigger uses standard five pin MIDI communication cables, sometimes
referred to as MIDI Plus cables. MIDI cables can be purchased from your
authorized distributor or dealer, or from an audio supply store.
1.
Turn all components off, using the back panel power breaker
switch. This ensures that the components are synchronized when
the MIDI cable is connected.
2.
Select the component to be the control component. The control
component must be in plain view for proper remote control oper-
ation.
3.
Connect one end of the MIDI cable to the Krell Trigger out con-
nector (17) on the back panel of the component.
4. Connect the other end of the MIDI cable to the Krell Trigger in
connector on the next component.
To link another component, connect a second MIDI cable to the
Krell Trigger out connector on the back panel of the second com-
ponent. Connect the remaining end of the MIDI cable to the Krell
Trigger in connector on the back panel of a third component.
5. To link additional components, if desired, see Steps 3 and 4.
The components are now ready for operation with Krell Trigger.
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
coupling capacitors from the audio signal path. Coupling capacitors
block damaging DC but have sonic characteristics that corrupt sound
reproduction.
