We began todays reviews with an exemplary wireless microphone model from Shure — their legendary SM58, this is a full system version as opposed to the just the microphone itself. The wireless S58 microphone is perfectly tailored for vocals and known for its bright mid-range frequency response and bass roll-off.Welcome to the Wireless Headset Microphones Store, where you'll find great prices on a wide range of different wireless headset microphones.

Headset microphones are great if you want to move about on stage or in a venue without worrying about how your voice will sound. Typically, these headset microphones consist of a microphone, an earpiece, and a power pack that also transmits to a receiver.

The biggest issue with any microphone is the amount of noise that is picked up by the mic. You want it to pick up your voice; what you don't want it to pick up is the noise of the drum or the noise of other people. The very last thing you want it to pick up is the noise of the amplifier itself, as this will create a feedback loop.

You have two main types of headset microphone to consider: directional and omnidirectional. When you're on stage with a band or with other participants, you want to have a directional mic, as this will reduce the amount of noise that isn't yours getting into the mic. However, these tend to be pricier, and they need to be pointed in the right direction in order to work properly. If they're not, these headset microphones won't pick up your voice as well.

Omnidirectional headset microphones can pick up noises from all directions, which makes them ideal when you're talking without any background noise. They can also be exchanged easily between people with little fuss, which is perfect when you need swift changeovers such as in a church or in a hall.

However, they are prone to picking up other noises that you don't want coming through the speakers, and they're notorious for producing feedback. So whether you're going for an OSP or JVC directional microphone or omnidirectional Samson headset microphones, choose the right one for your venue, and you'll get great sound every time.

Yes you can, using a 3. The lav mic included is a different microphone, and does not have a removable adaptor but rather a fixed 3. While both are broadcast-grade in performance, the Lavalier supports the MiCon adaptor system for a wide range of compatibility with popular audio devices. The more 2. In a very busy 2. Signal travelling distance is also another possible factor. An unobstructed line of sight between the two devices will provide the shortest possible signal travelling distance, therefore the strongest signal.

If the signal needs to travel through, or around walls and other objects, this lengthens your signal travelling distance, reducing overall signal strength. For more information on the 2. It is important to note that the more kits you have operating simultaneously, the more likely you are to experience a decrease in their useable range.

This is also relative to the environment you are operating in and depending on the amount of 2. This only needs to be a minimum of cm and typically will only affect usage in congested RF environments as well as when larger transmitting distances are required.

Always make sure that your receivers Rx are orientated so that the antennas are forward facing when using the Rx-CAM this will occur naturally if the kits are mounted via the provided cold shoe mount and the display is facing the camera operator. Of course, there is technology that can help with the background noise.We have searched the web to help you find quick design ideas. We make every effort to link to original material posted by the designer.

The circuit is completely passive and will work on dynamic and electret type microphones. Circuit by David A. Johnson P. This was necessitated after the number of E-Mail questions posed by people who were confused by the layout of the project s.

I do however, receive many requests for a higher powered circuit and better microphone sensitivity. This has been achieved by adding an RF amplifier buffer with 10dB gain and an AF preamplifier to boost the modulation a little. Not much to tell here.

This circuit was experimental and so has no real purpose other than tinkering. Despite its small component count and a 3V operating voltage it will easily penetrate over three floors of an apartment building. This FM transmitter Bug is very easy to build. The size of the circuit board is ONLY 22mm x 10mm.

Now I can introduce the new FM Wireless Microphone, which also has a better frequency stability, over 1Km range under ideal conditions and is good on microphone sensitivity. Got Designs? Custom Search. Schematics Index.

Imagineering Ezine.The FM transmitter is designed to run from a 9-volt battery and is made from readily available parts. The primary use of this simple FM transmitter is as a baby monitor. It is very sensitive, and easily capable of picking up a conversation in any part of a room.

The dimensions and values given here will allow static-free reception within the perimeter of most homes. No license is required for this small transmitter according to FCC. Audio is picked up from the room by an electret microphone and amplified by Q1. The amplified AC voltage from Q1 is routed to the base of Q2. Transistor Q2 and associated circuitry C5 and the inductor form an oscillator that operates in the MHz range.

The oscillator is modulated by the audio voltage that is applied to the base of Q2. Resistor R6 limits the input to the RF section, and its value can be adjusted as necessary to limit the volume of the input. That will help control the amount of distortion you have on very loud inputs.

Resistors R7-R9 set the DC-operating bias of Q2, another 2N that's used as the oscillator and modulator of the transmitter. Capacitor C5 is a pF trimmer capacitor that's used to tune the oscillator tank circuit, and C4 routes the RF from the oscillator to ground to prevent unstable operation.

The FM transmitter prototype is built on a piece of perforated construction board with 0. Component spacing is not critical, but placement is. Generally, you must make the transmitter as small as possible. A piece of perfboard that is 12 holes wide and 30 holes long, will give you plenty of room to work with, but still produce a small unit. During assembling make sure that the ground lead of the microphone is soldered to the ground.

The inductor is made by winding a gauge wire aprox. The C7 capacitor must be placed as close as possible across the L1 -Q2, R9, to reduce the amount of RF feedback you'll get into the rest of the circuit. The antenna 24gauge wire should be soldered to the coil you made, about 2 turns up from the transistor side, and should be about inches long.

To use the transmitter, set up a radio in the area at least 10 feet from the project. Find an unused frequency and turn the radio up so you can hear the static. Connect a 9-volt battery to the transmitter and listen to the radio. Slowly adjust the tank capacitor C5 until you "quiet" the receiver; this is the tuned spot. Note that when you remove your hands from the transmitter, you will detune the circuit somewhat. It is usually best to leave it detuned, and tune the radio in to get the best reception.

If you cannot get the tuning range you desire, you can squeeze the coils in the tank circuit closer together to lower the frequency, or pull them apart just a little bit to raise it. The circuit works best when powered by a battery, but if a wall derived supply is needed, make certain that the ripple voltage is as low as possible, or you will get hum in the receiver. Simple FM Wireless Microphone. No vote. The add to cart button will appear once you select the values above.

The Circuit Audio is picked up from the room by an electret microphone and amplified by Q1. How to build it The FM transmitter prototype is built on a piece of perforated construction board with 0. Operation To use the transmitter, set up a radio in the area at least 10 feet from the project.
