Humming noise through PA even though mics not being used

Using either balanced or unbalanced out puts of the WM200 ( canon or 6-5mm Jack plugs) into the PA (which is a Yamaha EWM66M series PA) I am getting what appears to be a constant hum through the system even though the Mics are not in use.....this noise lessens a little if I take the Mics out of the charger locations on the WM200 but still cannot use the system. Soon as I power up the WM200 unit I get the noise.....

SOURCE: Distortion within a certain frequency range for wireless mics on magic sing 11000

Because of the very wide dynamic range of the human voice, specially when singing, the microphone you use, needs to be smart(usually expensive) to do the job properly. When going cordless, the electronics needs to be even smarter. A windscreen will not solve the problem.
I do not know of ANY low-cost radio mic that would not frustrate you for ever and a day. Rather spend a little more and be happy.
If allowed, I can introduce you to a very budget tipe entry level radio mic, that would work much better: Beyerdynamic OPUS 168 mk2 This mic works on a diversity UHF frequancy that receives a very clear signal for at least 100 feet. It also works with a "compander" , that improves the dynamic range. You will propably pay about $300 for it, but it will last lots of years with much less frustations. Sorry, there is no inexpensive way out on this one. PA Master

Thats because your Rf is powerful on high settings..try taping a AM radio "ferrite bar" to your coax in the back of radio for "RF filtering". Keep your power supply 15 inches away from radio. I recommend unhooking talkback on radios (it always causes feedback). But make sure speaker is good distance from the radio. I'd say 10 feet or so, behind radio. Change external speakers or add one with a long cord.

What is the best way to connect a Yamaha MG102c to a Canon Xha1s?


It could be the type of cables you're using. Are they balanced or unbalanced?

The jacks on the end will tell you what type of cable it is.

If the metal jack (plug) has 2 circles, it's a three-conductor plug (TRS or "tip-ring-sleeve"), which means the cable is balanced. It's meant for stereo connections.

If there's only 1 circle, the plug is two-conductor (TS or "tip-sleeve"), meaning the cable is unbalanced. It's meant for mono.

There's a 3rd kind, (TRRS "tip-ring-ring-sleeve). It has 3 circles, which makes it a four-conductor plug. The extra ring is specifically made for microphone connections in 1/8 in. This is the one you would want to use for a cellphone connection, for normal operation.

But because of what you're doing, the connections and cables have to have to be specific, otherwise you'll end up with lots of noise and interference. It's much easier if you have pictures to look at, that way it won't seem so overwhelming.

This should be able to help. If not, just let me know and I'll do what I can to help you figure it out another way.

Just got shure sm58, plug it into my starsinger on the tele but sounds is very low compared to the crappy mics? i plugged up a mixer box and can get more sound now but should it work fine with the...


The SM58 uses balanced output. If the starsinger uses a 1/4 inch jack, it is unbalanced input and probbly requires a high impedance rather than the low impedance SM58 mic. You can get an impedance transformer to fix that problem.

Using Boss FV 50H between output of Tascam M-216 mixer and church PA (line input of main mixer) with microphones on 1 channel and guitars on other. Problem:Quite a loud "pop" or...


The problem is you have an ILLEGAL connection based on proper electronic design. This pedal has UNBALANCED high impedance interconnects and the output of your mixer and the PA SHOULD be BALANCED low impedance interconnects. This makes the system subject to noise and you may even get static discharge noise. Also verify that the TASCAM and the PA system are ALL powered from the SAME receptacle or power conditioning module. This is a tough design problem to achieve what you want. Essentially you want to make the master gain of the TASCAM on a foot pedal as I understand it. There is one pedal that CLAIMS to have balanced in and out and if I had the schematic I could verify it... but I could not find the schematic in my searches... look at: http://www.sweetwater.com/store/detail/StealthPedal
This one MIGHT do the job right. You MUST use TRS BALANCED cables, NOT TS, from the mixer to this and from this to the PA. Do research on BALANCED and UNBALANCED and TRS and TS and also XLR cables using google to understand the difference and importance of using balanced interconnections in your system. I would try to get one of these pedals on approval with the correct cables and test it.

I have the Phonic powerpod 820. I ordered a Kuston powered floor monitor to add too the system. I know not to hook it up too the speaker outputs on the back of the mixer. So where do I hook up the powered...


You will plug an UNBALANCED 1/4 inplug cable into the MONI jack on the front of the unit. The other end will probably need to be an XLR plug to connect to the Kustom POWERED monitor. Please note that the UNBALANCED output of the Phonic is NOT good engineering practice. The Phonic stuff is normally low-end and they don't do everything correctely, although for a small system it should work. IF you get excessive hum from using a long cable to the Kustom with a "Kludged" unbalanced to balanced cable, you MAY need to use a DI box at the Phonic end to convert the unbalanced Phonic MONI output to a balanced line (XLR to XLR) for a longer run to the Kustom monitor. You might get a 1/4 inch TS to XLR balanced plug that has a transformer in it and use an XLR to XLR cable to the Kustom. Please note that having this plug in the Phonic hangs out and is easily bent over so I would recommend using a right angle connector at the Phonic and plug the 1/4 inch TS to XLR adaoter into that so the yanking of the XLR cable won't break the 1/4 inch adapter off in the Phonic.

My school uses Sennheiser Mic's for it's PA system. Is there an adaptor that would let me connect my CD player to the PA sytem's mic jack via the CD player's 3.5 mm headphone outlet?


The CD is STEREO whereas the MIC is monaural.

One could make an adapter that merges the left and right channels before sending on the balanced XLR input. This involves using an audio transformer or direct input box for the balanced line and is not DIY unless you are elctronically skilled.

The best way to do this is to instead plug the output of the CD into the TAPE inputs that are usually available on the mixer.

One uses usually a 3.5mm stereo splitter cable with RCA plugs for most of them.

Connecting aux send on Tscam 2488 to input of TC Voiceworks


A 1/4 inch short instrument (mono) cable between the AUX unbalanced 2488 and the 1/4 inch of the Voiceworks should work. Operate ALL the equipment from the same power source to avoid ground loops.

You will lose 3 Db since you will only be driving one side of the balanced VW input, but there is plenty of gain. The sleeve of the mono into the VW will ground the - balanced input of the VW. The connection is absolutely safe. Should you encounter noise on the connection, use an isolation device like a DI and use ground lift with the 2488 into the mono jack of the DI and XLR out of DI into the VW. I think you will find this unecessary though in your use.

I am getting some humming from the speakers when I


Yes, use balanced cable to the PA system and use a DI at the computer end.

The DI is known as a "direct box" or "direct input" and converts the UNBALANCED computer output to balanced to send toe the PA system.

I have a low level hum in the MIC like a motorcyle in mt AT 4040


Remember this is a condenser mic that REQUIRES phantom power. There are several failures regarding this phantom power delivery that COULD cause your problem.

A "LEAKY" mic cable that is not a fully balanced cable can cause the problem. Test with another cable to exhonorate your cable.

A failure of the input bypass caps in your amp/preamp can cause the input to become unbalanced and let in hum.

A phantom power that is improperly filtered can also cause this. Test using a different source of phantom power.

Remember that you can easily get feedback that may oscillate like hum if you have a monitor speaker anywhere in "earshot" of the mic. They are very sensitive and intended for studio use.

To connect a mono mic cable into a pabx with audio out what do you do with the earth cable from the mic cable?


your talking about using a balanced cable to hook-up an unbalanced item. no problem, wire pins 1 and 3 together as a ground and pin 2 carries your hot signal.

i'm not sure what a pbax is though! either the rules applies to everything that is pin2 hot.

Disc tray on my playstation2 console


Hi KG45ZY,

 

I am guessing that you are running  a PS2 Blue Disc Game.  Blue colored discs tend to run faster than Silver or gold.  Accepted method for cutting the hum down  is to put a piece of Tape on the label side of the disc. jkeep trying that until the disc gets a good balance.  I just put up with the Hum and do not invest a lot of time in trying to get the hum out.  Thats the solution though, your Blue Disc is unbalanced.
