**** Under normal operating conditions the fuse  rating for 4 ohm loads will suffice for 2 ohm loads. If the amplifier is driven for long periods of time into

2 ohm loads per channel the fuse rating may be increased as shown.

++ Driving amplifiers with continuous sine wave power is very stressful and is not indicative of an 
amplifier’s real world performance. We actually prefer to use PINK NOISE as our test signal as it very 
closely replicates typical music which is what our amplifiers were intended for in the first place. Our 
amplifiers will double the 4 ohm power at 2 ohm when driven with pink noise

 

 

DO NOT OVER FUSE ANY AMPLIFIER.
