Questions regarding receiver - amplifier and diy SW
I have a Sony STR DN1080 receiver which has an LFE output that, according to the manual, has a voltage of 2V / 1kilo ohm.
Right now I am running the LFE to an ART CLEANBoxPro and after that a a Behringer NU3000DSP and then to 2x Dayton Ultimax UM15-22 subwoofers. Everything OK for now.
The thing is, to de-clutter my TV rack, I am trying to loose the CleanBox Pro and also get a nicer looking amplifier (Behringer NU series are ugly as hell) maybe even getting a 1U unit.
Most Power Amplifiers have balanced, and some also have unbalanced inputs. I.E. the Behringer EUROPOWER EPX3000 has unbalanced inputs with an Input Sensitivity of 1.17V and Input Impedance of 10 kOhms unbalanced.
So what does it means? The STR1080 outputs 2V@1KOhms and the amplifier has a sensitivity of 1.17V@10KOhms, does it mean the amplifier won't register enough signal from the receiver to amplify it?
I am just trying to understand what specs I am looking on an amplifier (and maybe on a receiver if I upgrade later) to have the certainty that the LFE signal will be powerful enough to properly feed a PA amplifier (plate amplifier are out, as I can't get them in my country).
Ideally without using all the LFE gain on the receiver and in the amplifier. Yes, I tried using the STR1080 directly to feed the NU3000DSP but I needed +10 gain on the LFE output and quite a lot of gain on the NU3000DSP to get signal output on the subwoofers, and even then the subwoofers had a weird "hiss" noise.
Finally, does the MiniDSP works as a line level (and unbalanced to balanced) converter like the CleanBox Pro?
Regards and thanks in advance for your help
