== Noisy Volume Controls ==

On {{S1 nl}} channels 1 and 2: When you rotate the volume controls back and forth within 10 seconds of turning on the unit, you may hear a scratchy sound.

This is not a symptom of a hardware issue with the volume controls that warrants concern.

The noise is related to a start-up process within the unit, not the volume controls. The noise you hear is not the result of a physical problem with the volume controls.

When you turn on the unit and rapidly turn one of the volume controls back and forth you may hear a noise. This can happen on either channel, 1 or 2.

After several seconds, the sound stops. At this point, the volume controls on both channels 1 and 2 should work as expected, quietly.

If you cycle the power off and back on, you can get the same result on the other channel, 1 or 2.

If you turn on the unit and let it sit for 20 seconds, the volume controls are quiet. That doesn't mean you have to wait for 20 seconds before you can use the unit. You just have to wait for 20 seconds if you don't want to hear the noise when you rotate the volume controls quickly.

On {{S1 nl}} channels 1 and 2: When you rotate the volume controls back and forth within 10 seconds of turning on the unit, you may hear a scratchy sound. This does not indicate a fault. The noise should stop happening once the {{S1 nl}} has completed its internal start-up routine (5-10 seconds).
