Title: L pad
Post by: jplaudio on March 24, 2004, 10:34:47 AM
L- pads can work as an attenuator for your amp, just be sure to overrate the L-pad for the wattage. I have used a RS 50watt L-pad for my DR but they get very HOT. A 100watt should handle a 35-40 watt amp but not a 100 watt amp. You may be able to find 150 watt ones.

yes. I was planing on geting the stereoversion, and stack the two pots to get 16 ohms with 2 separate speakerjacks ( isolated and separated grounds ) . that would give a total of 200watts wich is enough to take my amp...alternatively I guess they coulp be parralleled for 4ohms for 200watt...

actually it is! A high power one.

Only the 100W might be a bit optimistic......
