Evolution DC Protection Circuitry/Using Tube Preamplifiers
The high DC output of tube preamplifiers may exceed the active DC protection circuitry of the Evolution amplifiers. Excessive DC level in a signal can damage amplifiers, loudspeakers, or both. The
Connection Steps
Position the amplifier where you intend to use it in your system.
The following steps describe how to connect an Evolution amplifier to your sys- tem:
1.Turn off all power sources and components before connecting inputs and out- puts.
2.Neatly arrange and organize wiring to and from the Evolution amplifier and all components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being introduced into the system.
3.Connect the outputs of your preamplifier to the appropriate CAST (4), balanced (6), or

4.Connect the loudspeaker cables to the loudspeaker binding posts (7) on the Evolution amplifier. The binding posts accept spade lugs only. Take care to observe the correct polarity when making connections: The positive (+) output connects to the positive input of the loudspeaker. The negative
5.Connect the supplied AC power cord to the AC power cord receptacle (9).
6.Plug the AC power cord into AC power.
Note
Use only the power cord provided with the Evolution amplifier to make the connection 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 amplifier to perform optimally.
