Sounds good but what effects did you use?????

Bit of EQ, compression and a Reverb with a bit of pre-delay on it.. Nothing too drastic.

i am going to go out on a limb here and recommend that you get a condenser microphone. and get a gemini dj mixer.

http://www.8thstreet.com/product.asp?ProductCode=1542&Category=Microphones

I have that mic, and for the price I really like it. But if he gets it, then he's going to need phantom power, which means a pre or new mixer. Then he's going to need something else, and he'll be fucked with GAS just like all the rest of us. :)
Better for him to use and enjoy what he's already got I think.
 
oh shitska!

ok then he should get the mic and an audiobuddy!

the output of the audiobuddy can go into the input of the r/s mixer at unity gain!

rapper: the audiobuddy is a nice inexpensive mic preamp with phantom power!

you can get the sound you want with this stuff!

now is this rapper a bona fide or is he a wannabe? i mean is he more vanilla ice or is he more ice t? i mean is he an inner city minority or a white suburban?

Here's the cord you need to go from the mic/transformer to the mixer.

Your clip sounded ok to me - I think you can get good results with what you have now - upgrade when you know what you need.

Thanks "Crazydoc" & to whoeva else dat helped me :). I just have to start testin' out different equipment to see what will satisfy me. I'll probably buy me an audio buddy & see what'll happen then.

Pe:)ce :):):)
 
You're welcome, rapper. Glad we could help. :)

One caveat with the audio buddy - I have one, and it works fine with my condenser mics - quiet and clean, despite its low (about 40v) phantom power voltage. However, I think my SM58 sounds sort of dull through it as compared to my other pre, JoeMeek MQ3. If you get a condenser mic you should be fine, but I don't know how you'll like the SM57 thru it.
 
uh oh...

How do you hook the cable to the mic? Doesn't the mic have a 3 prong connector on the end?

If it's a cable with an XLR plug on one end for the mic, and a 1/4" plug on the other for the mixer, that's probably the whole problem right there.

(participant's eyes bug out as something dawns on him... puts tail between legs... whimpers some...)

:o :o :o

So very ashamed to admit, this may be the cause of the shtty sound I got from my Sm57 two days ago (see related post in "Guitars and Basses"). Oh god, I feel so dirty :(

:eek: :p

(sheepishly goes and hooks everything up with an XLR/XLR cable this time... :p )

hey!

maybe harvey can tell us all about microphone impedance and why some mics have 1/4" plugs and some have xlr at both ends of the cable and why cant they be interchanged freely and where does time go!

No jeap,

I think I'll leave that to you this time.
 
I'm sure Harvey will give a better explanation, but I'll give it a try until he chimes in.

First, the connectors. Most devices connected by XLR are low impedance, and most connected by 1/4" phone connectors are high impedance. So if you just hook one type connector on one end of a cable, and the other type on the other end, you'll likely have an impedance mismatch and the signal will be degraded.

Impedance
I like to think of it as a sort of resistance to energy transfer between two electronic devices- the output from one device has to be matched to the input of the other. If not, the right amount and kind of energy won't get from one to the other.

If you're riding a bicycle, you want to transfer energy from your legs to the wheels. You do this through the pedals and the gears. If you're going uphill and you're in a high gear, you have an impedance mismatch and you can hardly make the pedals go around. If you're going downhill and you're in a low gear, you have another impedance mismatch - you can spin the pedals fast without any resistance but you can't make the bike go fast (unless gravity takes over.) The trick is to be in the right gear for the given resistance to forward progress.

It's the same with electronic devices - you want the impedance of the accepting device to match that of the donating device. If not, it will not be able to tranfer enough energy, or will overload by trying to tranfer too much. In either case, the signal will be altered to its detriment.

Time
Time doesn't go anywhere. We are at the juncture of two eternities - the past and the future - which is precisely the present moment (to paraphrase Thoreau.)
 
Jeap,

Don't bag on Harvey, man. He knows his stuff and has been recording for more years than many of us have been alive. You could learn a lot from him. ;)
 
Looks like Harvey chimed in while I was writing my post - guess it'll have to do for now. :)
 
how is that bagging on him?

why would i try to get information from him if i didnt think he had lots to offer?

the mics from radio shack often say "low z" but have 1/4" plugs which (as crazydoc pointed out) are associated with high z.

z being impedence which is electrical resistance which is measured in ohms.

harvey could splain it. he is a fountain of information!
 
My bad, I must have been reading into from your previous posts. This internet thing is not always the most precise means of communication.
 
Well, not that it matters...

...but switching in an XLR/XLR cable didn't help much... a little.

Finally got a *decent* sound out of the SM57 using the PreSonus DigiTUBE (little bro of the BlueTube) and ditching the ART all together. Miked it just below the center of the speaker, pointed at the cone's axis. A guitar tone question remains... but that'll have to go in the other forum :( :confused:

:p

ps: Still no idea why rapmaster2000 couldn't get a decent sound ;)

It gets a little complicated to explain, but see if this makes some sense to everybody:

The advantages of balanced, low impedance signals are very little loss over long distances, double the signal strength (the - signal is inverted at the other end and added to the + signal), and relative immunity to induced interference and hum over the length of the cable run. After the signal is summed in the mixer or preamp, it's no longer balanced.

Low impedance, balanced mic cables are good for runs of a 1,000 ft. or more without significant loss. If you happen to be recording 1,000 feet away from the mic, you don't want the mic cable falling out, at either end, so a locking connector like an XLR system makes a lot of sense.

For short runs of 20 feet and under, there's not a whole hell of a lot of difference in the sound between balanced and unbalanced mic system. XLR connectors are a lot more expensive than 1/4" plugs and in many cases, manufacturers have opted to accept unbalanced, low impedance signals on 1/4" plugs.

Many of the 4 track cassette recorders with built-in mixers will use 1/4" plugs for low-impedance signals. Why spend a lot of money on plugs and circuitry that will only improve things if the mic cable run is super long?

1/4" unbalanced plugs are certainly acceptable for short runs and the manufacturers who make lower end equipment understand that it can be a significant savings without affecting the performance drastically.
 
You're a rapper, shouldn't you being using the Shure U Series cordless system with a beta87a? Hold the mic by the windscreen, and sorta wave your fingers in the air?
 
so the cables are interchangable????

we can use the cable with the 1/4" plug with an sm57?

we can use xlr to xlr with our radio shack mics?

and theres no probs?

why do ppls always recommend the transformer things as if you HAVE to have them to convert 1/4" to xlr and vice versa?

why?


tyler of course is right again! you have to go cordless and hold the mic upside down by the windscreen and wave your fingers just right. but that for performance only isnt it? in the studio rappers must have the best condensers to capture their nuances right?
 
jeap said:

With low impedance mics into low impedance mixers, yes, the cables are interchangable, as long as the pre doesn't care whether the signal is balanced (with an XLR or sometimes a 1/4" TRS plug) or unbalanced 1/4".

we can use the cable with the 1/4" plug with an sm57?

Into preamps that are designed to accept low impedance, "unbalanced" 1/4" mic level signals, yup, you betcha.

we can use xlr to xlr with our radio shack mics?

With R/S mics that have low impedance, balanced mic outputs on XLRs, into preamps that can accept low impedance, balanced signals thru XLRs, yup, you betcha.

and theres no probs?

With unbalanced signals, there's more chance of hum pickup and induced noise, slightly lower output, and you're limited to shorter cable runs (under 50 feet), but in most home studios, there won't be any problems.

why do ppls always recommend the transformer things as if you HAVE to have them to convert 1/4" to xlr and vice versa?

why?

Because a lot of "ppls" don't understand how this stuff really works. Some mixers and recorders are designed for use with high impedance sources.

To plug a low impedance mic into a high impedance input, you need to convert the mic's low impedance to high impedance with a transformer to get a proper transfer.

You read the mic specs to find out the mic's impedance; low impedance is usually any number under 1,000 ohms. High impedance is around 10,000 ohms or higher.

You also read the specs on your recorder and mixer. If it says low impedance input (and it's a 1/4" input jack), you don't need a transformer. In fact, a lo to hi transformer will seriously degrade the performance in that situation.

Understanding how the signal moves thru the various pieces of gear and "gain staging" (figuring out where to set the knobs for highest output, with the lowest noise and distortion) is one of the hardest concepts for new recordists to grasp. Set the levels too low, and you're giving noise a free ride; set the level too high and you distort on the loud stuff and bring up room noise on the soft stuff. Setting the gain too high too early in the chain can cause distortion in all the rest of the gain stages. Most of the "my sound is crap and I'm not pegging the meters" problems happen because the first stage amplification is too high, and turning the signal down later won't reduce the distortion.

Hold the phone - I was wrong about my suggestion on the impedance matching transformer yesterday. I went deeper into the RS website and read the specs on your mixer - it does have a low impedance input (600 ohms) so this is not the problem. Sorry about that. I still don't know why your SM57 sounds like garbage.

Harvey
Thanks for straightening me out on this. I had remembered that RS sold a lot of high impedance mics in the past and erroneously assumed (making an ass out of me) that the inputs on their equipment was high impedance also. I guess the mics were for plugging into guitar amps and the like.
Learning from mistakes is a great way to learn, especially public mistakes.:)
