2388.0. "Problem: Yamaha MV802 mixer + pad-less house board" by TALLIS::SEIGEL () Tue Jul 10 1990 19:26

I've run into a problem playing out live at certain clubs.  Not all, just
some.  The problem is real simple: the signal coming out of my mixer
(Yamaha MV802; XLR connectors) is real hot, so at clubs where the main board
does not have pads, I have to cut the levels way back.  So far back that
my amp does not receive very much signal (certainly not enought to hear well
enough live).

The MV802 has 4 outputs: 2 stereo pairs, one pair of XLR connectors, one
pair of phone.  The phone plugs go to my amp, the XLR's to the house board.
The manual clearly states "XLR and 1/4 inch phone plug outputs may be used
simultaneously..."  In fact, I've never seen this problem until I hit
City Limits in Lynn, then again at Jumbo's.

So, what I'd like to do is build a portable 2-in, 2-out pad box, with XLR
connectors, and 1 switch to implement the "standard" db cut (20 db?).  This
way, I could [hopefully] cut the signal to the house without affecting the
signal to the amp.

Anyone out there got plans for such a beasty?

Thanks much...

    	If you were to run mono instead of stereo, you could have
    	an adjustable level for the house feed totally independent
    	of your stage mix. Just pan everything straight up, you take
    	the left Main Out mix, the sound guy gets the right. Most
    	house systems are mono or dual mono anyway and any benefit
    	from a stereo mix is left on the stage.

    It might still be cheaper to build a pad box, but you could always
    hook up a direct box (or two) to the 1/4" outs.  Assuming you use one
    that has a pad (most do), just kick in the pad, run out the XLR to the
    board, run from the 1/4" out of the direct box to your amp.

re: .1

Indeed, the thought has crossed my mind to run in mono live ...

I'm really confused.  Hook up direct boxes to the 1/4" outs, pad them, and
send them to the amp?  The problem is too much signal to the board.  Or, do
you mean send the 1/4" to the direct boxes and then to the main board?   In
either case, can you just buy a direct box?

thanks...

    Most direct boxes take either instrument (guitar) or line level inputs.
    They then have an XLR out and a 1/4" out which is just wired in
    parallel to the input. Most also have a pad, so you can feed 1/4" line
    level in to XLR mike level out, but doesn't affect the 1/4" out.   
    
    So : key mixer 1/4' out to DB 1/4" in; XLR out to house PA, 1/4" out to
    your amp
    
    Obviously, doing the mono thing is cheaper as you don't have to lay out
    any $$.

    Andy,
    
    I also have an MV-802 and when I was playing live I ran it mono.  This had
    a couple of advantages:
    
    1.) Independent control over stage volume and send to PA.  This came in
        very handy at several locations.
    
    2.) Sound engineers at clubs didn't go ballistic on me for asking for
        2 lines for keyboards when they were near the edge on having enough
        inputs the house PA console.

2388.6Mono it is...TALLIS::SEIGELThu Jul 12 1990 11:5113
re: .5

Well, I still have independent control, as my amp has attenuators.  But, as
you say, I've occasionally run into a club soundman who looks at me like I
have 3 heads when I tell him it's stereo.  I mean, they're already totally
confused that I don't need a direct box!

Meanwhile, I'm convinced.  Mono, here I come!

thanks, all...

    well......if you're running stereo you'd need *TWO* direct boxes...
    ...so that doesnt seem real good.
    
    I run MV802 as a sub mixer (synths/guitar). That feeds a
    small board that adds mics...I swear by MV802 for HIGH Quality vs.
    cost ratio line mixer, BTW, for all you cheapo's like me out there...
    
    I think in your situation I'd do the mono route, as was noted...
    one side to 'monitor' and one to house...
    
    One option not mentionned is to create a monitor mix from the
    effects sends. Since you have 3 per channel, just crank each
    up (a bit) to get something outta the send jack....and send THAT
    to the house.....
    
    (yes, it's not affected by foot pedal mix or 'end volume' controls,
    but that CAN be an advantage...)
