    2x QSC 3500 amps no power up?

    I got 2 QSC series 3 3500 amps about 1 month ago and I ended up setting them up for home use connected through a dbx 2 way crossover. One for high and the low frequency. I had a set of speakers that I have been using for quite some time with other amps and have had favorable results no matter...

    How Quiet is Quiet? (power amp fan)

    I picked up another older QSC amp recently. This is is a CX6, and its fan is much louder than those in my USA 900 amps. The CX6 uses a 24 volt 120mm fan, which appears to be fairly common. The problem I'm finding is that I don't know what to look for in a new fan; CFM is one thing, but so is...

    Weekend 'Scores' AKA More Stuff

    Over the weekend, I picked up another QSC USA 900. I like my current one, the price was right, and a backup is always good. While I was there, I helped the seller get rid of more stuff, as he was cleaning out his garage. I'm now the new owner of a couple Pioneer tube receivers, an SAE...

    'New' Pre-amp and Setup

    In my daily scans of Craigslist, I came across a McIntosh C31V fairly local to me for a good price over the weekend and decided to check it out. I was impressed with this 30 year old - it looks 95% new, seem to function perfectly, other than a little noise in the balance control, and included...

    QSC Amp and DBX Crossover

    In the quest to find a way to connect my SVS subwoofer to my Luxman receiver, I decided to try an electronic crossover, if I could find one cheap. A guy had a DBX 223XL for sale. At $25, I figured that qualified as cheap. I went by his house on Saturday, and he had a bunch of his stuff which...

    Hafler XL-280 versus "professional" amplifiers

    I like my Hafler a lot, but my Maggies (MMG) could use a tad more juice. How do the professional amps like the Crown XLS series, Yamaha P series, and QSC pro amps work with a 2 channel music only system? (open to other as well, those just seem to be popular) Are they going to ravage my Halfer in...
