Troubleshooting System Noise

When you mix and match high-performance audio components, each with its own ground potential, a low frequency hum may occur in one or both loudspeakers.

If this happens when you place the Evolution Two preamplifier into your system, follow these simple troubleshooting steps.

1.Check that all input and output connections are of sound construction.

2.With the preamplifier channel off, remove the interconnect cables, the turn the preamplifier channel on. If the hum disappears, turn the preamplifier channel off and reinsert one of the interconnect cables. Turn the preamplifier channel back on. Repeat this process for each cable.

3.If the hum reappears with one or both interconnect cables reinserted, the cable needs to be replaced.

4.If the interconnect cables are sound, you may be experiencing a ground loop. Please contact your authorized Krell dealer, distributor, or Krell for suggestions on how to eliminate the ground loop.
