    Battery Backups

    I just had a thought, maybe someone with some more technical knowledge than myself could chime in. I see people saying that battery backups aren't ideal for audio usage because they create a not-so-perfect sine wave AC output.. but I was thinking that since my amps are rectifying AC into DC...

    How in the HECK...

    do I use those connectors that go onto power input modules (Mouser PN: 538-19003-0001)? I had some awhile ago, but couldn't for the life of me figure out how to attach the wires to the connector. Do I need a crimper?

    Balanced CMoy

I will take a quad 132 opamp from TI, specifically the OPA4132UA, and pop it into the standard CMoy circuit, using a browndog adapter. Since I use HD580s and they have higher impedance, should I have to...
