The following steps describe how to connect an Evolution Two preamplifier to
your system:
1.
Connect each power supply chassis and preamplifier chassis with the 12-pin
DC cable provided, using the DC power connectors (47) on the back panels
(1-2).
IMPORTANT
Never connect two power supplies together.
2.
In order to operate the Evolution Two preamplifier in linked mode, connect the
preamplifier channels together with the supplied RJ-45 control cable. In linked
mode, functions including power, volume, balance, phase, record, mute, and
input selections are instantaneously transmitted between linked preamplifier
channels.
When a system with linked Evolution Two preamplifiers is powered on, left/right
orientation is established immediately, with no user intervention. For more
information on linked preamplifiers, see Appendix: CAN Link and Multiple
Evolution Two Preamplifiers, on page 51.
3.
Neatly arrange and organize wiring to and from the Evolution Two preamplifier
and all components. Separate AC wires from audio cables to prevent hum or
other unwanted noise from being introduced into the system.
4.
Connect the outputs of your source equipment to the appropriate CAST (34),
balanced (30), single-ended (31), or tape inputs (32, 33) on the Evolution Two.
5.
Connect the appropriate main outputs (35-41) on the Evolution Two to your
amplifier.
6.
On each preamplifier channel, connect the supplied AC power cord to the IEC
power cord receptacle (48).
7.
On each preamplifier channel, plug the AC power cord into AC power. The
front panel display (15) scrolls through
EVOLUTION 2 SOFTWARE VERSION,
and the
red stand-by LEDs illuminate (4), indicating that the Evolution Two preamplifier
is in stand-by mode. The scrolling stops when the Evolution Two is ready to be
powered on.
Note
Use only the power cord provided with the preamplifier channel to make the connec-
tion to AC power. Operation with a power cord other than the one supplied by Krell
could induce noise, limit current, or otherwise impair the ability of the preamplifier chan-
nel to perform optimally.
