For years I've avoided this type of device as I regarded them as just expensive, rack-mount power strips.
But I'd like to try one to see if they actually work.
Seems like the PFR is a power conditioner that is supposed to reduce noise from dirty power?
And the AR is a voltage regulator that is supposed to maintain a constant 120v +/- 5v regardless of mains voltage? But it also has "some" power conditioning/noise reduction?
My priority is noise reduction. But voltage regulation could be nice since my mains runs hot sometimes, like around 125v. And then at night when the power grid gets taxed, it drops down to 120v. BUT... if this thing has a tolerance of +/- 5v is it really gonna do anything?
The noise reduction for each one is listed at:
PFR:
30 dB @ 2kHz
40 dB @ 10kHz
50 dB @ 20kHz
70 DB @ 100KHZ
AR:
10 dB @ 10kHz
40 dB @ 100kHz
50 dB @ 500kHz
Is the PFR really going to reduce line noise better? Seems like the AR filters noise at a higher frequency, but less noise attenuation at 10K - 50K. And the PFR filters down to 2K, but stops at 100K. I have no idea how to interpret this shit lol.
