We had enough clients with this humm problem and others like; distorted audio, static noise.
Unresolved by REL we recently traced out and examined the schematic and found several simple mistakes.
About the humm. The balanced speaker level input is simply miss designed. As a result it does not reject noise or hum. Solved
If using the high level input, there is distortion at anything above watt. A second design flaw, solved.
At high levels using any input the sub sounds like the amp is clipping or the woofer is bad. It can even sound like a flimsy cabinet. A third design flaw limits undistorted ouput to few watts. Again solved.
The woofer, amp and enclosure are fabulous. Once the electronics are overhauled the sound is too.
