Clipping mains - need solution; vocal clarity help also needed

#23
Pickles...on another more simplistic experience I found the 835's a little more challenging than others Ive used. Ive had to run up the gain pretty hot to get a decent signal and quickly approach feedback issues... we switched to akg c5's and not an issue as of yet.

I had a question regarding all this. At my church we have a pair of loud speakers and one sub. Right now all of our inputs are going to the loud speakers. The bass guitar and kick drum are going to both the loud speakers and the sub. Is there a way I can get everything below 100hz or so to go just to the sub?

This is the board we're using:

We have the sub sends on an Aux channel.

I would not send the bass DI signal through the FOH in a 50-200 people bar gig, especially if I'd own your Aguilar rig. I'd bet that the kick is not the problem here, but the bass is or, most likely, both (added amplitudes) together. To not have the kick mic'd would not be an option for me, rather cut it's low frequencies a little, and more important: no bass through the PA!

Yes, You should be able to assign a 31 band graphic EQ to each of the outputs. L- R and AUX (?). Then use the graph to roll off everything below 100, or reduce it significantly,on the L - R outs, and the the reverse to the AUX out. Roll off everything above 100. That should do the trick.

ha! you've actually stumbled into a half-assed version of a fairly advanced technique called "aux-fed subs"!

the kick and the bass get sent to the subs, and everything else gets left out of them.

if you want only 100Hz and below to get to the sub (as you should), you need an active 2-way crossover. you can score a used ART, DBX, or something for $100 or less.

the easy, normal way goes:

board==>main EQ==>crossover (xover point around 100Hz)

crossover high out==>tops amp
crossover lows out==>sub amp

if you want to keep the arrangement you've got, then just send that aux out to the crossover, and the crossover's lows out to the sub amp. it'll work just like it does now, except the sub won't have any mids or highs in it, so it will sound better.

I don't yet have a sub, but I would like to mic the kick at next month's bar gig, so I've come up with a temporary solution.

I have one side of the Crown K2 free (ch.1 is feeding the drummer's monitor; ch. 2 is not being used). I also have a spare bass cab -it's an old Peavey 1820 (1x18, 2x10 and a horn). Could I run a direct out (sub, aux, or direct out) on the kick drum channel to the amp to feed this bass cab as a temporary subwoofer? That would solve the clipping mains issue.

it'll work (i don't know how well).

i kinda like the idea of taking the direct-out of the kick channel, putting the box by the drummer and thinking of it as a "kick drum amp" to go with the guitar amp and bass amp, just beefing up stage volume a little and getting the kick out of the vocal boxes.

Exactly my thoughts. As the bassist, I'll certainly play better being able to hear a healthy dose of the down beat. I'll report back on this one (the gig is a few weeks out yet...).

Another noob-ish question: I'd like to daisy chain a pair of Yamaha A15 tops. Each is 8ohms. Each has parallel inputs (one speakon, one 1/4"). My amp has banana plugs and I bought a pair of banana to 1/4" speaker cables. So- check me on this - I run the amp to the 1/4" input of one A15 and then connect its other input (the speakon-which will effectively become an output) to the second speaker's input. Is this correct?

The parallel input teminology is confusing as I believe the second input becomes an output when daisy chaining:help:

This is a pain in the arse

*sigh*

So, if this works out, the amp will see a 4ohm load. Each A15 is rated at 4oo watts continuous and each channel of my Crown pushes 800 watts into 4ohms, so this would seem to be ideal.

Assuming that my bass kick drum amp and daisy chaining scheme will work, the bar-band PA will be as follows:

Mains - Yammie A15 tops daisy chained in mono on amp channel 1 for mains; add one channel of Ashly 31 band eq
Monitors - Mackie Thumps; one for the vocalist (aux send 1), and one for the drummer (aux send 2)
Subwoofer - kick drum as needed via amp channel 2 to 31 band eq to Peavey 1820 bass cab (temporary solution)

This leaves no eq for the monitors, however.

all that looks good; the two tops will give you parallel for 4 ohms no matter how you patch them in to that amp channel, so that's fine.

i'd submit that the vocals are more important than the kick drum; as such, i'd use the other EQ for the vocal monitor, so you can get it sounding OK and loud enough for the singer without feeding back. kill everything below 100 (maybe even 120) on the vocal monitor for best sound.

be careful with the "kick drum amp"; you could blow that cab pretty easy this way, so just crack the amp's volume open until you hear the kick get a little "power" behind it. (if you could knock out everything below like 50 on the cab it would be good.)
