    Least expensive online place for Mackie or QSC Amps?

    Patrick, congrats on you HT Forum award. I just picked up another amp for my sub system, a QSC USA 900, it has a fan but the next smaller one down does not, the USA 400 200x2@4ohms or 400 bridged I am sure it can be had cheap if you look around. The QSC USA 900's fan is much quieter than...

    Least expensive online place for Mackie or QSC Amps?

    Patrick ,the m-1400 has a fan, its kind of loud about the same as your computer power supply fan. I have mine sitting very low to the ground and after awhile it really is no big deal, youll never hear it at louder volumes, I can't hear mine at anything over 80dB.You'll get used to it after...

    I would personally be less interested in a voltage metering than just a basic nominal output test: 1) Hook you your receiver subwoofer pre-amp output to your mackie amp. 2) Disconnect your sub speakers from the amp [just to be safe]. 3) Set the volume to 50% (high noon if it is an analog...

    Thanks for the informative post Vince, just to let you know my Sony 555ES analog outputs are rated at 2v into 1K ohms, while the Mackie's input is 1.23V into 4ohms, a difference of about 3 tenths of an amp, or the Sony does have a higher voltage but has more resistance. This all means that...
