Questions and Answers

SECTION SEVEN

Q.Should I leave my Evolution amplifier on at all times?

A.For maximum amplifier performance, leave the back panel power breaker switch on at all times. This places the amplifier in stand-by mode. Evolution amplifiers are designed to be powered on and off from stand-by, using the front panel power button. This eliminates “cold start” degradation. The amplifi- er will operate at full performance within minutes.

Q.When I turn on the amplifier there is a loud hum through the loudspeakers. What should I do?

A.When a new component is introduced, a low frequency hum may occur in one or both loudspeakers. Check all input and output connections and cables, making sure they are of sound construction. See Troubleshooting System Noise, on page 24. If the interconnects and cables are sound, you may be experiencing a ground loop. This can often be easily eliminated. Please con- tact your authorized Krell dealer, distributor, or Krell for suggestions on how to solve this problem.

Q.My loudspeakers are rated for 150 Watts. Are the Evolution models too power- ful for them?

A.No. A loudspeaker seldom is damaged from overdriving. More often, damage occurs when an amplifier that lacks sufficient power is asked to handle heavy demand situations such as high playback levels. These amplifiers may have very high 8 Ohm power ratings, but in heavy demand situations they can be driven into clipping (in which high power, high frequency harmonics go to the loudspeakers, due to loss of amplifier power). Clipping can damage loud- speakers. Avoid damage to your loudspeakers by reviewing your loudspeak- er’s specifications, and exercise caution in heavy demand situations.
