Parts Express HPSA1000 and HPSA500

boostick4 · 17th February 2006, 03:42 AM

I've read that the Parts Express HPSA1000 and HPSA500 have a rumble filter set at 18Hz but can't seem to find this information on their website. I've also read that the HPSA500 does NOT have the rumble filter. Can some one please advise me on which information is correct? Does the HPSA1000 have a rumble filter and can it be defeated? Also, does the HPSA500 have a rumble filter and can it be defeated? Thanks

Given how similar the 2 are, I would have to imagine that both have the same rumble filter, which is 3rd Order @ ~18Hz from what I understand.

Here's a good page that describes it and some mods to the preamp board.

Hope this helps!!
