Howdy João!!
Welcome to the Voodoo Forum!!
Glad to have ya here.

We have heard allot of TS-2000's that sound just excellent.
Especially with the EQ mod from N3GX.
You shouldn't have a problem with that rig.

The mic is also a good one with a great choice in the mic preamp.
That should work very well for you.
The FBQ-2496 is also another great unit.
With all of this equipment you should be able to make some very, very nice audio.

Now to try and answer your question...
That is probably the hardest thing to do, to try and help someone set up there EQ without ever hearing there voice.
It is almost impossible.
We can try and give you some starting points, but in the end, it will be totally up to you to tune the EQ to your voice for it to sound the best.

This is where most give up.
They will try and try and get fed up with it and quit before they even have given it a chance.
Were going to tell you, We have spent 100's of hours TX'ing into a dummy load trying to learn how to set up my EQ.
Then once you learn how to set it, then you spend another 100 hours tweaking it to were it sounds the best.
THEN when you think you have spend even more time tweaking your tweaks to sound even better!!!!
Ha ha ha ha ha!!! It's a vicious cycle!!

But truly, its all in the ears.
You must listen to it.
Then learn what you have to change by hearing the sounds.
If it sounds bad at a certain frequency....find it and change or shape it.
These are the 2 most important things to learn.

#1 - Learn how to adjust your equipment and what each control is used for. Study it. There is allot of information on the internet to do just this. We have spent countless hours reading and researching this so I could learn how to do it. The information is out there.

#2 - Learn to LISTEN to your audio. Allot of people use Spectrum Analyzers, which is a very useful tool; BUT you must also learn to use your ears. This is one of the most important things.

OK with all that said, The best place to start will be with some general settings.
First of all you must go threw your rack and be sure all the gain levels from unit to unit are good.
Be sure that none of the INPUT meter peaks are over -3db in INPUT Gain.
Especially into the FBQ-2496.

OK set the EQ into PEQ mode (parametric eq).
We'll give you the following settings for a basic starting point.
It should sound good when it is in there, but as we said earlier, it will require you to tweak it for optimum sound.
This is almost impossible to do without actually hearing it over the air.
We'll give you the settings in Frequency, Bandwidth then Gain.
Here we go......

Frequency = 90cps
Bandwidth = .75 octave (3/4 octave)
Gain = +4

Frequency = 160cps
Bandwidth = .5 octave
Gain = -15

Frequency = 320cps
Bandwidth = .75 octave
Gain = -3

Frequency = 520cps
Bandwidth = .75 octave
Gain = -6

Frequency = 900cps
Bandwidth = .75 octave
Gain = +4

Frequency = 1.8kc
Bandwidth = .5 octave
Gain = -6

Frequency = 3.2kc
Bandwidth = .5 octave
Gain = +4

Frequency = 4kc
Bandwidth = .5 octave
Gain = +8

Give these a try and see how it sounds.
If you have a real bassy voice then you might have to reduce the 90cps frequency to 80cps or 70cps and perhaps reduce the gain.

If you have allot of midrange in your voice, then you might have to reduce the 320cps or 520cps Filters some more in gain.

The Highs will be the hardest to set. You want to push enough to get some brilliance and clarity, but without having a Compressor, you won't be able to push allot of them with out "Tearing" on sibulance.
The secret here is to keep the bandwidth narrow, and just adjust the gains.
The Frequencies should be perfect for you on the highs.

The 1.8kc filter is for Brittleness reduction.
It should be good is set up as shown.

The 160cps filter is for boomyness and boxiness.
It should also be good as shown, if your voice Fundamentals are from 100cps to 200cps, maybe reduce the gain another -5db to a total of -20db.

Also, as We don't know your voice, Watch the 900cps filter. If it sounds too Nasally, then reduce this filter gain to 0 and see if it goes away.....if it helps then reduce it to -4db.

You can see how you must adjust to your voice.
All We can do is give you a starting point but you must do the finish work.
Good luck João!!
Let us know how it works!
Take Care,

> thanks for nice help
> about how it sounds now..., i must say it sounds better!!!!
> but i want to get perfection...hhiihihihihi.
> My voice have a little bass, so i have low freqs on it , my changes are: reduce the 90cls filter to 70 cls and 900cls filter gain to -4
> and now sounds much better, but i believe i can improuve the quality.
> At first contact with your configurations it sounds strange, nasality but with your tips , now is starting sound great , i must say that i don,t have amplifier only 100watts , but now, i want to send you a recording of my audio but i don,t know how to do it, can you help again ?

Ohye!! Recordings!

No problem on the help João,
It's what were here for. He He!!

Spreading that Voodoo Audio like a Virus!!!!

We're glad you are getting it to sound good.
Thats whats its all about.

MMMM, about the recording.
You might have a problem with that.
Especially trying to do it yourself.
These are the 3 ways that recordings usually get made:

1) Someone else with a good flat receiver (like a TS-870) could make a MP3 recording of you on the air.
Then this person could email it to you.
Of course he would have to be set up for this.
Having an audio input from his receiver to the sound card of his computer.
This is the easiest way.

2) You use a second flat Receiver (like a TS-870) and make a MP3 recording of yourself to the computer.
This is the best way, that way you don't have to ask all the time.

3) Use your rigs TX Monitor to make a MP3 recording of yourself to the computer.
This unfortunately is NOT usually a good representation of your Transmitted audio.
Reason being is that most Transceivers TX monitors are not flat.
The High and Low Frequencies are usually attenuated in the Monitor, in other words they do not pass threw into the Headphones.
The TS-870 and the Flex are the only 2 rigs We know to be True.
The TS-2000 unfortunately is not.

Well other then these 3 options we know of, no other ways to get a good recording of your Transmitted Audio.

OK João....Keep Spreadin that Voooooodooooooo!!!
Take Care,

Well only if there is extensive modding done to the radios to get a flat RX. I'm not sure about the TS-2000 since I've heard guys talk about firmware updates. Also the '2000 LE owners are claiming it's receiver rivals the '870--jury is still out on that. :roll:

I'm still having orgasms from listening to Steve [KB8GFF] last night on his TS-2000. If you've heard Greg [UDX] then you see what I'm talking about... :twisted: It proves the '2000 has the capability--has already been proven by Alex [N3GX] years ago.

Howdy N6AQ,
Welcome to the Forum!!!

To answer your question,
Each separate frequency is a different filter.
So in the case of the above base start-up settings, that would be 8ea parametric filters.
