YOU’RE DONE. GO PLAY

 
There you have it: a quick and easy process to help you get the perfect tone 
from your Nemesis amplifier. As previously mentioned, it make take a few 
extra minutes the first few times you go through this, especially if you take 
the time to experiment with all the knobs and switches, which we highly 
recommend. 
 
We are confident that the time you spend getting to know your new friend is 
an important investment, one that will pay off immeasurably in 

Great Bass 

Tone

. And, after all, that’s why you bought an Eden, right? 

 

OTHER CONSIDERATIONS 
 
Suggested Speaker Systems 

– Your speaker system should be chosen to 

accommodate the characteristics of your amplifier and your predominant 
application. If you will only be using one cabinet, a 4 Ohm model will draw 
the most current from your amplifier. If you will generally be using two 
cabinets, they should both be 8 Ohm models so their combined impedance 
will be 4 ohms. If you are uncertain about your future needs, always go with 
the 8 Ohm speaker option so that you can add another speaker later if you 
need to. In general, adding more speakers will give you a greater volume 
increase than adding a few more watts. 
 
We have designed our amplifiers to operate safely at 2 Ohms only because 
everyone else is doing it and some users expect it. However, we much prefer 
operating at 8 or 4 Ohms because of the markedly improved quality of tone 
and dynamic response. But if you really want to, you can operate your 
NA650 at 2 Ohms without worry.  
 

Headphone Jack as a Line Driver 

– On some occasions (such as high-

volume or outdoor situations) it may be desirable to use the NA650 along 
with an additional power amplifier and added cabinets. A standard shielded 
instrument cable may be used to connect from the headphone jack of the unit 
to an unbalanced input of a standard power amplifier. This will provide a 
signal that is post-EQ and after the Master Volume control, allowing the 
entire system to be controlled from the NA650. This way, you only have to 
adjust one set of knobs. This is a 

Really Neat Thing

, huh?
