Anybody tried using both sets of the Nady DKW-Duo mics in the same room? Are they working together without interfering with each other?

I have been using the B/D set for Karaoke. I needed more Mics, so I ordered the P/R and they won't work together with the B/D, they interfere with each other. Nady says they should work fine, so I'm not sure whether to send them back and try another set. It may just be a bad set.....

I know, here come the 'Expensive Mic Snobs', and I really don't want to hear it. The Nady DKW-Duo is GREAT for Karaoke Singers, they sound about as good as a Shure SM58, and they're CHEAP! Not a big deal if someone drops one......

Just needing to know if anyone is using both sets together without interference?

Thanks.

That's sure the right attitude to try and ellicit help. Insult the experienced folks on this board by calling them snobs. Nice.

I'm not an expensive mic snob, I'm a quality snob so I'll help you out here. There is a good chance that the interference you're running into may be related to the environment you're using the mics in. There's this cool thing called inter-modulation interference where two devices broadcasting on separate frequencies can interfere with each other. There are actually equations for figuring this out. Now where intermod gets really hairy is that two devices interfering with each other through intermod interference can actually have a cumulative effect on a third device operating on yet another frequency. Let me explain. So you've got a microphone that operates on a single specific frequency. Alone it works fine and with no other RF in the area may work fine with a second mic operating on a different frequency. However, if there is other RF in the area (say a television station), the first mic may not have an issue with it, but if the second does, the cumulative intermodulation of that second mic and the TV station could result in intermodulation interference with the frequency of the first mic. This stuff get's really crazy fast, as you can tell.

So this is why a frequency agile system is such a huge advantage (frequency agaility being a feature of more expensive mics). With your mics locked into one frequency each as is the case with the Nady system you have, if there is environmental interference, you're stuck. My guess is that this is what is going on. I seriously doubt that it's a defect with the units you have, just a design limitation.

So before you go insulting people for having more expensive mics, I would recommend that you seriously consider why they may have them. Frequency agility, multiple balanced outputs, coil isolation, diversity receivers - all of which are features of more expensive mics that have nothing to do with tone but make a huge difference in application. It isn't always just about sound quality, although you'll never get me to believe a Nady microphone can sound anything like an SM58.

You can talk about how much you like your Nady as much as you want, but don't expect people to stay silent when you say utter rubbish like "they sound about as good as an SM58". No they don't.

If you say "they are good enough for me", fine. Or "I think they are pretty good". Knock yourself out. But don't expect me to be silent when you say "they are good enough for karaoke". They aren't. They are good enough for people who don't care how they sound, or perhaps more accurately how their singers sound. I hear this attitude all the time from tenor and female singers who think that just because they have eq-ed the mic so they sound good, that everyone will sound good. (I suppose there are cases where baritones eq so that females sound bad, but I haven't heard of it.)

I have stayed silent about the VocoPro 5800 because I sing through them weekly and they seem like they might be fairly acceptable if equalized properly. Unfortunately, the same ears that think Nady and VocoPro sound great are also equalizing the mics, which means they are usually off.

letitrip, simmer down fella. You are choosing to be insulted when you don't need to be. Don't like his comment? Click to the next thread.

I totally understand what he meant. There IS snobbery regarding certain equipment and especially microphones. He asked a specific question about a specific product looking for people who have first hand knowledge of that particular make and model, not a general question. He wasn't asking about SM58s or Vocopro.

I own and use corded Sennheiser e835s, Audio Technica wireless, Samson wireless, and the Nady DKW-Duo. I get paid to sing. I've done 16 one hour singing/seminar gigs for a corporate customer in the last few months. I entertain several times per month. Nine out of ten times I use the Nady DKW-Duo because they work great, they work every time and they sound just fine. They are the perfect Karaoke mic. Cheap, reliable and decent sounding. I wish I had an answer to the OP's question, but I only own one set.

The microphone that consistently makes my voice sound it's best is my least expensive microphone, the Nady SP-1 corded. My second favorite is my Sennheiser e816s tied with the $100 e835s. I also have a CAD GXL-2400 large diaphragm condenser mic that I would use at my shows, but it's prone to feedback and it's not shaped to fit comfortably in the hand. It's a studio mic. It makes my voice sound great, I paid $45 for it on ebay.

Funny, I expected it might be a losing question either way I worded it, and I was correct!! I was trying to find someone using the Nady Duo, without the lecture about cheap mics....Yeah, I could have worded it nicer.

How is what I said more offensive than bashing and lecturing anyone using a cheaper mic for Karaoke gigs? I do get sick and tired of reading the aloof comments when anyone asks about a cheaper brand..... Most Karaoke singers wouldn't hardly know the difference in ANY mics, and I'd rather them drop a $50 one than a $500 one.

Should have expected I would have got the lecture either way...

Simmer down, I didn't think I was fired up? I'm not insulted, but I'm sure people here are. My point was if you're asking for help, why start by insulting people? I'm not an expensive gear snob, I look for a good deal as much as anyone. I also have certain features I like and am willing to pay for. My point was don't assume that folks are snobs just because they buy expensive gear. I know there are those that think price is the determining indicator for quality, and I don't agree with them either. But understand that many folks have legit reasons for spending more and I pointed those out.

As far as a lecture, the only lecture I see that I gave was on wireless technologies and how interference occurs, sorry I thought that would be useful information in this discussion.

Letitrip: I just wanted to thank you for taking the time to post an excellent educational answer. The original poster of this thread may not have appreciated the value of what you posted, but I want you to know that others do. thank-you.

The OP wasn't asking for an education, he wasn't asking for information about other products, he wasn't asking for a commentary about the mics he was using. He was asking a specific question about a specific wireless microphone system.

He knew, just like I know that people love to promote the products that they use and they feel like their choice of product is superior. Sennheiser people think their mic is better than Shure, and EV and Shure people think their mics are better than any other mics out there. Many of these people wouldn't even think of trying a less expensive product because they're convinced that it can't possibly be any good. I've used LOTS of different mics over the last few years and I've had several surprises.

I compare different mics regularly. I know that the more expensive mics are almost all excellent sounding and high quality. I also know that there are other brands and models that aren't as well known that perform well and in some cases the difference between the expensive models and the inexpensive models isn't that great.

The answer given by Letitrip directly related to the question asked.
He gave a technical explanation as to why the poster's wireless mics may not work together in the same room. This is very useful for troubleshooting issues when using different wireless mics. Giving the principles behind why something may not work helps in all situations and where noone may have actually used the specific mics in question together. Even if someone posted "ya they work fine for me" or "no they don't work for me", the question still remains: why not for the poster? An answer based on technical principles is the best answer, in my opinion, because invariably, the next question would be *why* are 2 sets of mics that are supposed to work in the same room not working.

Also you might try turning the gain down on the mics. It may be case of the mic picking up room reverbs and not at the point of feedback.Does the interference vary in different parts of the room? When mics are held close together that can cause problems too. Does the receiver have a squelch adjustment for each channel?


The system I started out with in no way compares to the one I have now but it paid for it.
