I cant seem to solve the problem of getting a better sound from the singers it sounds tinny. Ive lowered the highs on the mic channel but doesnt seem to help much. I currently use a DFX 12 mixer and shure 58 mics. I do not have an external EQ and the only effects processor I use is on the mixer. Any suggestions on improving the quality of sound on the vocal end as far as the harshness.

Ok how is the rest of the eq (5 band) set & the music channel eq?  You said you had the BBE 882 at one point?  You may want to incorporate that into the mic channels only cutting back on the hi process - not a solution...may help though, at least worth a shot.  You said you set the JBL speakers from the sub to "hi-pass" in another thread, that's fine.  How does the music sound in comparison to the tinny mics?

If all else fails, may be time to upgrade the mixer to one with a sweepable mid control on the mic channel eq.  A good 31 band eq (such as dbx 231) on the mix may be of help as well, cutting back a couple of the harsh frequencies - usually in the 2khz, 4 khz or 8khz range.  May try that first, cheaper & can ALWAYS use a good eq.

What kind of speakers are you using and how high are they off the floor?

JBL EON G2's 15, 6 feet off floor




5 band is set flat & the EQ on the music channel is flat. I only bring down the high on the mic channel

nevermind.....

I dont think I have ever recommended RTA on a forum before it does get technical but I have used this for years when I suspected problems.. I actually put a real dual sweep scope on the inputs and outs run a signal thru and see if it is passing specs.. All Mackies including the  dfx12 passes or exceeds all the specs... I dont remember now but I think you can check the freq response on mics.... I use 58's on a dfx12 with no problems but I never did like the low pre gain although it does pass the specs...

Look's as though Behringer and Roll's are the folks that have the measurement mic's and  preamp devices in this area. Interesting. (at least the affordable spectrum measuring equip).  Can this also be done on a standard Oscilloscope with a microphone ?

Things to try:
Change mic cables:
Drop the speakers closer to the floor and cut some of the bass:
Try dropping the eq at about 2500-3000 Hz down a bit.
Make sure the mixer is well grounded.
Back off the Mic trim and increase the volume.

Hope one of those works....

Based on the equipment described you should have a decent sound-
Double check all your connections - inputs and outputs and make sure all are correct.  I assume the speakers are working properly ?
Try and borrow another mixer ? maybe something just isn't working on the DFX12
You migt have to do a little trial and error to locate the problem ..assuming there is a problem with something

Let's start over....If I remember correctly, your first post involved muddy bass....We discovered you had patched incorrectly into the Sub and was not using the high pass filter input, right?.....So let's start over and remove everything from the signal chain except the player, the mixer and the amp/speakers.

Connect the player to the stereo input on the mixer, then patch from the mixer main outs straight into the speaker "full range" inputs......Twist the mixer EQ knobs all straing up.....place the mic input gain straight up also....increase the mixer master sliders to maybe 2/3'rds it's travel....Then increase player strip slider to music is loud enuff, then increase mic channel slider til mic is loud enuff....Does it still sound tinny?

If you now have decent full range sound, then reinstall the other components one at a time taking care to make certain each is patched in correctly using the proper cables and connections....As each is installed, test the system and take time to fully learn the controls for each device.....

Just go one step at a time till the system is fully reassembled and your sounds quality increases with each device.

If at any step, you lose sound quality, then that device is either faulty or you have it connected or adjusted wrong.

P.S.

Make sure the input selector push button on the EON top cabs is in the proper position!....One position is line level, the other is mic level....It WILL make a BIG difference!

I think the post regarding the bass was in regards to a blown speaker, we just figured out through questions that he also had things hooked up incorrectly through the sub & that he was pushing his bass too high - which might be part of why he thinks it sounds tinny now because he was used to the bass.

Everything else seems to be hooked up correctly & he did state that all his eq's were zero'd out except for the mic in which he dropped the highs.

Yeah, but it was a simple switch out of position that got him last time....That's why he needs to check the input switch fersure.

Those powered cabs are set up to accept a mic straight into them...That's so folks can use it as a speaking PA.

They can also be driven off board outputs.........He needs to be set up for line level input, not mic level.....All he needs to do to check is look at the mic/line switch and see if it is in or out.

This is not a likely cause but, make sure the phantom power is off.

Pretty sure this isn't the cause either.

What do mean by tinny?  That brings to mind a small transistor radio with no base and the extreme highs are distorted.. Is there any distortion at all with a normal speech level  or at a higher level?  If there is no distortion does it seem with ALL frequencys it shifts the phase or does it just doesnt have any lows?..  A high frequency drop off is caused by capacitance to ground essentially filtering to ground.  A low frequency roll off is caused by a capcitance in series or an amp that the coupling impedance is suffering at low freqs ( a capacitor will not pass dc and presents a high impedance to lows)

With all the eqs flat I would turn all the fx off bypass all the procs and listen with cans right out of the mixer. and compare with the mains out.  I run 58's with a dfx12 and outside I can talk to people a block or 2 away in a normal tone of voice and they always say it sounded like you were standing right there... Vocals are in the middle of the spectrum and normally arent affected that much by freq problems (unless they are severe) and  shouldnt sound tinny....
