[QUOTE="bbeljefe, post: 8213204, member: 655960"] Yes, set the eq points to zero. And the part about the crossovers was obviously not well worded. What I mean it to turn off the crossovers but since a lot of amps don't allow that, I set them as high as possible for low pass filters and as low as possible for high pass filters. Also, that's not really important for DMM setting, because you can't see distortion regardless of what frequency it's at. But the point is that you don't want to cut any frequencies when looking for distortion because there could be some noise on the line that could be attenuated or completely hidden with a crossover turned on. In any event, disregard that part. :-) The reason for disconnecting the speakers during setting is that you don't want any load on the circuit when you're checking output. You want the amp to be sending a true voltage signal and that might not be the case when it's under a load. Not to mention, a 1kHz tone played at high volume for any length of time is enough to drive even the most sober man to drinking, lol. And yeah, if 20 volts is the amp's maximum rms, then 18 volts would be peachy. If you have a bass knob, set gains with it turned all the way up and if you like it, use it. I use them and they don't create problems. As for your last comment, you're technically correct. Unless you have a clipped source. But with a clean source low volumes low volumes can't cause the amp to clip so long as the voltage is equal to or lower than the gain setting. In simple terms.. The gain and volume knobs are essentially the same things. And so is the bass knob. It's just that they're designed for different purposes. And you're welcome. I appreciate the kind words. [/QUOTE]
