 ==== Hiss ====
-If you have all settings on the {{PS1}} set straight-up (including the {{R1}}, with nothing connected, it is not unusual to have an audible hiss. The reason: The System is pretty much running wide-open at full power with no input. If you had a microphone or a recorded source playing - the System would be extremely loud. If you were performing at these settings the hiss would be inaudible.
+If you have all settings on the {{PS1}} set straight-up (including the {{R1}}), with nothing connected, you may hear an audible hiss within 6-10 feet.
+The reason: At these settings the System is running wide-open at full power with no input signal. If you use a microphone  or a recorded source playing with these settings - the System would be ''extremely'' loud. Provide an input signal source with appropriate trim settings and and the hiss should be inaudible.
+Solution:
+Use the {{R1}} to lower the Master Level when you have no input signal source.
