    i finally got my rmx 1450 in and connected everything:
    yamaha pb1 -> rmx1450 -> avatar 212 8ohm (handles 1000watts)
    i have the high and mid on the pb1 at about 7, with the bass at 3. when i turn the gain to 3 o'clock and the volume on the pb1 to about 6 i get clipping when i play the e. i've yet to play with my drummer with the setup, but it doesn't seem like my rig is loud at all, and it clips like crazy. i've searched and found bits and pieces here and there on things similar to this but i'm curious what others put their gain at on the rmx but keep from clipping. oh, i would wait longer to post, but we've gotta a show thursday and we don't have a chance to practice before then so i can't play with the drummer till we play live. thanks for any and all help.

    I just got a new head and was having similar troubles with mine. When i asked most responded by saying to lower the gain control. My head doesnt have a gain control though so I had to fiddle around with how i had things set up. Definatly try lowering the gain, and then mess around with ur EQ to get the same sound
     
  3. The PbI has a very powerful gain section, turn it down and adjust the level via volume and eq section, that might help.
    If you're not doing so, run the 1450 bridged, your cabinet has an 8 ohm impedance and your QSC will only run with 1/2 the power.

    at the risk of sounding unknowledgable, there isn't a 'gain' knob on the pb1...are you talking about the level knob? and according to QSC schematics i have the 1450 set to bridged with the switches on the back, but both signal lights still light up when i play, though the channel two knob doesn't do anything.

    Bridged mono uses both channel outputs, so you should see both signal LEDs light up.
