    Difference between US Acoustics USA2050h and USA2050

    Just wondering what the difference was between the two? The manual shows the specs as the same, just says something about mixed mono/xover settings as the only real difference.

    Just wondering if any Zed heads would know............

    I think the H stands for high pass on the crossover.

    The standard model only has a lowpass crossover.

    That was on the top of page 4 of my USA 2300 manual.

    The xover settings are the same on both versions.

    Pic of the manual for your 2300?

    The US Acoustics manuals I have on page 4 are the specs for all models of the amps.

    Per page 4, it says only "the H model may be switched for high pass", but never having one I cant say 100%.

    I dont have a scanner, so I'm not sure how to copy it.

    That page of specs you posted is on pages 2/3 of this manual.

    The part I've been talking about is under the title "STEREO OPERATION" (for 2050H, 2050, 2075, 2100, and 2150), and below the 3 instructions for connections it has a section called "NOTE:" where it says that only the 2050H can be set for a high pass operation in addition to the low pass the other models can do.

    I can't wait btw............

    I have one BNIB 2050h atm and all the manuals show the same. I'm hoping the 2300 manual shows something different.

    I'm just wanting to know what the difference is. The boards between the 2050 and 2050h were different but weren't different if that makes sense.

    The 2050h board was actually stamped 2030 (which I have never seen an externally marked USA2030). The xovers pots on each amp was visually different but I have no clue if they held/hold different values or settings. The end caps are marked the same on each amp.

    Re: Difference between US Acoustics USA2050h and USA2050

    I wonder if the 2050H is 2ohm mono stable like the 6300,as the 2050 is only 4ohm stable mono mode?You Might/should be able to send Steve an email @ZedAudio.com,and get a true answer for certain.Im sure one of his engineers,or he himself can give you that information man?
