The parties in this drama are the owner of a small PA system, loaned to a local club, a friend recently "trained" by the owner to run the system and thus #1 sound man, and me, who had studied the manual and experimented with the system for months before my friend and the owner got involved. It's an amateur situation, so my "demotion" to #2 is only an annoyance, not a career problem. What's important is the sound itself.

The owner insists that the graphic EQs (one for the mains, another for the monitors) should be set to, and remain, a "smiley face," with the curve up about 6 to 10 DB at each end, and #1 insists on complying. That works more-or-less for the mains, but the monitors are very prone to feedback: vocal mics like to squeal with feedback at the high end of the smiley face, and guitars like to boom with feedback at the low end. So I think the "smiley face" EQ for the monitors is just wrong, but the owner has never actually come around in the evening to listen.

The owner and #1 insist the solution to the feedback is to use the channel EQs to compensate for the smiley face: every guitar channel should have the bass turned down, and every vocal channel should have the treble turned down. I think that just gives us two EQs fighting each other in unknown ways, and messes with the main mix to fix the monitor feedback. Absent proper measurement to tune the graphic EQs to the speakers in the room, I think (after a lot of tweaking) that the main graphic EQs should be started out flat, then tweaked a bit by ear, each channel's EQ should be adjusted to sound good in the mains, and the monitor graphic EQ should be adjusted to minimize feedback (a bit of a frown) at some cost to how good the monitors sound. Is there a right and wrong here? Or is it just opinions?

Another problem is that the #1 sound man likes to record off the main mix, and thinks that once the sound check is done the mix shouldn't be touched, since changing things ruins his recording. I think that in an open mic and jam session context the mix needs constant tweaking as players and singers come and go, and if he wants to record he should bring in his own mixer and use the channel inserts -- then he can have a recording mix that is independent of the house mix. Again, is there a right and wrong here?

Reminds me of the improvement in sound I made for one karaoke guy by
(with his consent after I'd described and let him listen to a recording
of the problems) putting the EQ on the backing tracks to flat and a
slight (3dB) smile on the output. Then tweaking the vocal to sound as
good as possible. It got rid of the bass clipping where he had the bass
full up on the backing track input and the bass full down on the output.
He was amazed at the improvement.

There is no single "right" way, but the way that your boss and #1
operator seem to want things set in stone is, IMHO, one of the wrong ways.

A slight smile on FOH will compensate for a long, full room to a degree,
and the smile should be bigger the more people there are in the room,
but the monitors should be set to minimise feedback, with maybe a notch
at the worst frequency, however the settings are unlikely to be those
wanted on the front of house feed.

Feeds for recording should be before EQ if you have no warning about the
performance, as EQ and effects can be easily added post facto. If you
want to give the artistes a quick and dirty mix, then take it off the
FOH feed by all means, but if you have time later to edit, take another
feed off the effects sends if your desk will let you do a track per channel.

Just my two penn'orth....

Others with more experience will be along shortly. :-)

That's what I was doing before I got outvoted. A slight "frown" on the monitors that notched the lowest and highest frequencies and kept the guitars from booming and the vocals from squealing. Got occasional complaints that the monitors had too much midrange, but most folks accepted my explanation that the alternative was painful feedback. (I once watched the "Reverend" Al Green cursing out an incompetent sound crew that couldn't keep his mic from squealing.)

The board has per-channel, pre-EQ, pre-volume feeds that can be sent through #1s own mixer for recording.

Worth more than that, thanks.

As ever. Thats why I'm here, after a too-long absence. Nice to see how many of the wise ones are still here, putting up with our stupid questions.

Well, keep the smiley face, but then when it feeds back, pull down the
slider corresponding with the note that is feeding back and stop the
feedback.

Usually people will do the smiley face thing in an attempt to hide severe
problems somewhere else in the sound chain.

The channel EQs are very wide.... the graphics are narrow. Use the graphics
to control feedback, use the channel strips to alter tone.

In fact, most graphics are pretty damn wide and you are better off with a
proper parametric or digital notch filter to control feedback. But the
graphic is nice in that once you have a good sense of pitch you can just
pull the slider down and stop it.

Feedback is inexcusable.

What is more important, a good recording or good house sound? If you are
being paid to provide good house sound, that should be more important than
the recording. If you're being paid to make a recording, that may be more
important than good house sound. Who is paying the bills and what are they
paying the bills for?

Don't you have a couple prefade auxes you could use for his recording?

Which eliminates the smile, as it's the lowest and highest sliders that need to be pulled down. That's why I found a slight frown more effective than a smile. But #1 and the owner don't want the monitor smile touched, so all the mics have to get their (too-wide) treble controls brought down instead, killing the FOH vocal sparkle in order to kill the monitor feedback, requiring more FOH smile, which makes the guitars too sparkly ...

> > Usually people will do the smiley face thing in an attempt to hide severe

Yep. I'll buy John's experience that the smile can help balance the FOH sound in a large, crowded room, but don't see the point for monitor speakers, which are operating very close to the musicians and microphones.

No kidding. And at circa 10KHz it really hurts.

The house, I'd say. #1 doesn't see the conflict.

Nobody is paying me and #1 anything beyond a free beer or two. We just like having open mics and jam sessions, and don't mind some work to make it happen. I don't know what the arrangement between the owner of the sound system and the owner of the club is. The owner of the club just wants to have people there drinking, and the better the sound the more that happens.

> Don't you have a couple prefade auxes you could use for his recording?

Yes, we have one per channel, pre-almost-everything. #1 just needs to get eight patch cords. He already has an adequate mixer.

Which are the highest and lowest sliders, so no more smile.

I can buy John's notion that the smile can help balance the sound in a large, crowded room, but don't see the point for monitors. Monitors, IMHO, should be as flat as possible, so the musicians get honest feedback on their sound.

Exactly.

And the board lacks parametrics.

And circa 10Kz it hurts.

As far as I'm concerned, the house mix rules, though #1 uses the recordings for marketing.

Me and #1 aren't getting paid beyond a free beer or two, just pitching in to support the local musicians in this tiny mountain town. A surprisingly large number of surprisingly good musicians, at that. I don't know what the arrangement between the equipment owner and the club owner is. But the club owner wants drinking customers which the music helps to draw.

> Don't you have a couple prefade auxes you could use for his recording?

We have pre-almost-everything sends on every channel, and #1 has a good small board. He just needs some patch cords.

Thank's Sean. I agree that the solution is with the people involved. I'm trying here to get clear enough on the tech to be sure of my advice, and have come away more confident, thanks to John and Scott. The equipment owner thinks he knows best how to use his gear, but never shows up for me to discuss things with him, so I was thinking I'd need to convince him.

But a few minutes ago my friend #1 and I decided to set up my own gear, so I'll be the expert, and we won't have to argue it anymore, and he won't feel caught in the middle. One problematic person out of the equation. And maybe, with a bit more gear and practice, we can make some money providing sound to people who appreciate a crew who actually listens.

Right, that's why using broad filters to control EQ is a bad idea.

What you want is a super narrow filter right on the feedback mode, so it
notches it out without affecting the tone audibly at all.

The owner of the sound system, then, gets to decide whether recording or
PA quality is more important, because he's basically paying the bills.
If he wants a good recording and doesn't care about the room sound, that's
his business. Mind you, I'd get rid of him for that, but that's not my
decision.

We live in a world today where very few people are willing to pay for good
sound. Or even barely adequate sound. I get calls asking me to do club
gigs and I tell them what it will cost and they hire some kid with a behringer
instead.

Which is probably the correct thing to do if the cost of hiring you and the
artist means they will make a loss, but stupid if they pay big money for an
artist who draws a big crowd and deserves/can justify the expenditure on
decent sound. One simply cannot expect that the smallest of gigs will rate
the same sound expenditure as stadium concerts!

However a kid with a Behrenger and reasonable speakers, who knows what he's
doing, can still provide acceptable sound in a small room. Or really screw
it up if he doesn't know what he's doing. Likewise many huge concerts with
big budgets and big ticket prices still get screwed badly! :-(

The story I told of Al Green ready to strangle a sound man was at the fairly large Telluride Blues Festival. For what I had paid for tickets they could certainly have afforded competent engineers. But no. For Al it was a 10 KHz squeal that should have had someone immediately grabbing a high treble control, and then more slowly dialing in a precise parametric notch. And of course, the initial setup and later sound check should have caught the problem much earlier. And for a later gospel show in a small theatre they couldn't figure out where the very low feedback was coming from. And I'm thinking, what do you think your 75 Hz rumble filter is for? Do you really think female gospel singers produce any sound that low?
