[QUOTE="squeak9798, post: 1483606, member: 555320"] Yes, but the only possible thing you will gain there is a better SNR (signal to noise ratio). If you had no audible noise with a 2V signal, going to 4V will not gain you anything. No. 1kw is 1kw, no way around it. Not really. The amplifier is still producing 1kw. The same amount of power is still flowing through the amplifier. Most amplifiers were designed to safely produce rated power output with as little as .2V I know this is a total oversimplification....but essentially what you are doing with the gain is decreasing the level of the input signal so that the amplifier will produce rated output power, but yet not clip while attempting to do so. With a higher preamp input voltage, you need to decrease it more. That's all. [/QUOTE]
