3. Connect the Krell CAST cables from your CAST-enabled preamplifier or
source component to the left and right Krell CAST 4-pin bayonet inputs (16)
on the amplifier (1) back panel. For balanced operation, connect the intercon-
nect cable from your preamplifier to the balanced XLR input (15) on the ampli-
fier back panel.
4. Connect the loudspeaker cables to the amplifier binding posts (17), located on
the amplifier back panel. Amplifier binding posts accept spade lugs only.
5. Insert the AC mains power cord plug into the IEC power cord
receptacle (20), on the back panel of the power supply chassis.
6. Turn to Amplifier Operation, on page 22.
Note
If a CAST and balanced source are connected to the amplifier during the initial installa-
tion, the Evolution One amplifier defaults to CAST, when it is powered on. If only one
source is connected, the amplifier will automatically select that source. For more informa-
tion, see
Switching Between CAST and Balanced Inputs, on page 23.
DC Protection Circuitry / Using a Tube Preamplifier
The Evolution amplifier has a built-in DC monitor that continuously monitors the
audio signal at the input. If too high a level of DC is detected, the amplifier auto-
matically mutes the output and engages DC coupling capacitors at the input
stage.
