need some help setting up hi fi audio

[543_Dallas]

thanks for the info my west coast friend ill keep messing with it the more i do the better it sounds i do need to pull somemore bass out of it its like mmm at the moment but i want that more fidelity sound like you got but everyone cant be the same every station has that sound that makes them them.. mustang 131 keep on keepin on my friend ill talk to you soon tootall 170 working that tower of power in the keystone

i was thinking of buying a digitec studio s200 for more effects to get that compressed sound but i think a electrovoice re20 would be my next investment buy a good mic and go from there

Turn the bass down around 100hz. Frequencies in that neighborhood will make you sound muddy and boomy.

Be sure you aren't overmodulating or have any clipping on the audio gear. It will cause distortion that a lot of guys have confused as too much bass. They start screwing with the eq and never make any progress.

Try to use the eq to reduce the undesirable frequencies. Don't boost anything in the beginning. Once you get a good sound listen closely and try boosting some frequencies to see if you can make any improvement.

Invest in a dummy load if you don't have one. Ive spent hours talking to myself and no one else had to hear me.

i took care of the problem. he wont be hearing anything. until he finds the tiny transmitter i built. and hid in his culvert. all he will hear is metallica enter sandman..

 

[jon666]

he only uses one channel 6

I wish more people would realize this.

That sounds pretty elaborate. I hate to keep getting this thread off topic but if you want to start another thread with details I'd be interested.

its just a simple fm transmitter. easy to build. he is running around his house trying to find it.
funny to watch. its only good for about 500 feet.
i never give away my secrets. i had the build plans for years.

I heard a rumor that Uncle Charlie recently sent out some warning letters to some malcontents on 40 meters. Haven't seen the letters yet but evidently they got the them and then bitched about them OTA. Wrong idea...

Not sure if the FCC posts warning letters. Maybe only when they are acted upon with citations.

100hz-20,000hz for less than 20 bucks. Let's see who gets this done first......

You're going to drive yourself nuts trying out all the very usable and highly affordable condenser mic elements available on the market. Just pick out a frequency range and response curve you like and go at it. Even Rat Shack had a desirable version for like 2 bucks.

It's not too often you run across the perfect housing with an opening on the front and rear..
I just figured I'd share that in case somebody decided to take on a project.

Without a doubt a perfect housing for a NC project, but w/o looking on EBay, how readily available is that old model Shure?

I would bet that mic would have better voice quality if the impedance was 600 ohms or less since most mic input impedances are around 600 ohms.

When you use a high Z mic into a much lower impedance input its like forcing a 4 inch water line into a 1 inch line. The result will be too much resistance, not letting all the water pass. With mics this will mean many voice quality frequencies will be blocked from being passed. In the pro audio world, this would give a dull and lifeless sound that I doubt any sound engineer would accept unless purposely going for an effect.

Impedances don't have too be matched, but they shouldn't be substantially higher than the input. Many pro mics are around 300 ohms and will pass excellent voice quality audio just like running a 1 inch water line into a 4 inch line, no problem because the all the water will flow into it.

RK 56 mics are high Z mics and while they do have thier own sound, I find it to be dark sounding where as the Astatic 636L is 200 ohms and sounds more open and clear to me.

On CB radio, it is a personal preference.

they seem to be a dime a dozen on eBay

It's really easy to build an Attenuator pad to match the impedance as well as attenuate the signal to whatever amount you need.

That's what I would do. Build a simple project box with a mic in and out and use some impedance transforming resistors to get the impedance down.
