First of all, I am not an engineer (in fact i am a lawyer) so please understand that I am not that technical, and I will not properly understand a highly technical reply.

So, to the question...

My DSP has an output sensitivity of 0.9Vrms and my amplifier has an input sensitivity between 0 - 1.42Vrms (according to spec sheet), so I think I will be OK, as the DSP output is enough to drive the amp normally, maybe not up to clipping it, but enough.

The thing is, what happens when I want to change the amp to a one requiring more Vrms (less sensitive) and balanced input??

Can I solve my problems installing between the DSP and the amp, an unbalanced to balanced converter with a +6dB gain?

I understand a dB value is a ratio of something, and citing this site:

http://eaw.com/docs/6_Technical_Information/StudyHall_and_TechNotes/dB_calculations.pdf

"If you simply state something in dB then you are only stating the ratio in between one thing and another. So you might say

the difference in two voltages is 6 dB but that only means one voltage is twice the other (6 dB = 2 times

voltage). It doesn't tell you anything about the actual voltages."

So, does it mean that if the unbalanced to balanced converter has a +6db gain means it will double the voltage of my DSP?? meaning it will output close to 1.8Vrms or 7.32dBu??

Thanks in advance!
