UFO 2.1 Maximum Gain
04/24/24 at 14:23:54

Hi, I have been looking and cannot find my UFO 2.1 maximum DB gain. I want to use it to bi-amp and would like to know its max DB gain to help choose another amp that matches. I know I have the attenuation knob but if I choose another amp with more db gain it won't help. I would like to start on the same baseline for both amps.

Sorry if it is already in the posts and I missed it. Does anyone know maximum DB gain of my favorite little amp?

Thank you,

Eric

I don't recall ever seeing that number, so if that is what you need you probably should email Steve.

But, as a practical matter, and JMO/FWIW and all that, I think you may be over-thinking this. The gain from the amp is only part of the equation. Between the volume control on your source and the attenuation in your UFO2 you have a huge range of available output from the amp, which is what actually matters (along with the efficiency of the speakers). You can try it yourself (if you haven't already) by connecting the UFO2 to your tweeter and trading off gain from your source with attenuation in the amp. I would be shocked, shocked, if you couldn't find a wide range of settings that worked with any other amp of your choice. I recall a few other posters who have used UFOs in bi- or even tri-amp setups and the idea that the other amp(s) would not be compatible never came up. If it were me I'd be much more interested in finding an amp I "liked" vs. one with the right gain.

Good luck regardless, keep us posted with your journey.

Maybe I'm being dense but I don't see it, and search doesn't find it either.
