Pop is happening when I go from standby to on or sleep to on, tried all the turn on configurations including a trigger. Just to note, I'm using a McIntosh MX-132 preamp.
Tried making some homemade XLR shorting straps between pins 1 and 3, pop is now gone when I turn on the amp but is now more noticeable when I turn off the amp. It does not fully extend the woofers, though.
I have 6 amps and they all do the same thing, which tells me its something else in my system. Also, since the homemade shorting strap had some effect, I'm hopeful thats the issue and a stock shorting strap might fix the issue.
I'm also hoping to find a XLR preamp or even use the XLR inputs with an RCA to XLR adapter. Let me kniw if anyone in LA has an XLR preamp they would like to part with.
Thanks for all the help,
