Share on Facebook It used to be that if you wanted to create a karaoke system in your home, you had to connect regular XLR-type microphones to a high-output amplifier and purchase an expensive disc player to plays CDG karaoke discs. With modern karaoke systems, though, all the hardware needed to sing along to your favorite tunes is inside the microphone. With karaoke mics such as the ones made by Magic Sing, EnterTech and Magic Tech, you can set up the system with your TV and start singing in a matter of minutes. Plug the AC adapter cord for the karaoke mic into the mic base stand and an available electrical outlet. Do not turn on the mic or insert into the base unit yet. Step Connect the yellow, red and white RCA cable that lead from the microphone base to the corresponding input ports on the TV. Note the name of the port on the rear of TV that you use to connect the RCA cables from the microphone base. For instance, the port might have a “Video 1” or “Video In” label. Step Open the base of the karaoke microphone and insert fresh batteries. Also, insert the song chip for the microphone into the slot labeled “Chip” or “Song Card” if you have not already done so.

Power Supplies A constant current source source can supply a fixed current to a load regardless of input voltage or load change. The LM is quite useful as a constant current source, works on a wide input voltage range, from 3V up to 40V. The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation.
With 12 volt DC it will deliver 1 watt RF power.
Coils are 22SWG 7mm air core.
That coax feeds the antenna connector that is mounted into the top of the speaker-microphone. Two points about the straight-cord public safety speaker mics also called PS speaker mics: If the antenna is not there you WILL damage the transmitter. If you have to use one in that fashion then put a piece of black tape over pin 13 on the accessory connector to force the radio to use the antenna on the radio.
They were designed for UHF only, and will provide a rotten match i. The actual antennas that were made for the PS speaker-mic are specifically designed for the UHF speaker-mic application and are more rugged and somewhat shorter i.
What We Offer
I got it partly because I have used Canon Powershot cameras for years and liked them, and also because it has an external microphone jack built in already, so there’s no need for special mods or trying to mix sounds in your PC. All other microphones I saw had to connect to a special input shoe, and that shoe doesn’t work with my camera.
Nobody else seems to sell any other mike or adapter for this camera, and I couldn’t find any info on the pinout of the connector to make one myself. Somebody has got to figure out how to make an adapter and attach a reasonably-priced microphone or two to this camera Add Tip Ask Question Step 1:
The gating circuit must be driven from a signal generator, for example the Neutrik Minirator.
Connecting Basic Computer Mics 1 Examine the jack on the microphone. Generally, most basic computer microphones will have one of two varieties of jack: Both of these jacks have corresponding ports on most computers. If you’re using an XLR microphone, a quarter-inch jack, or some other variety of mic, skip to the next section. Almost all desktop computers will have visible microphone ports on either the front or the back of the tower.
Usually, this port will be colored pink, and have a microphone image over it. If you have an eighth-inch jack, all you’ve got to do is plug it into this port and start testing sound. If you have a USB jack on the end of your microphone, most computers will have two or more USB ports on the side, or the back of the computer. Simply plug the USB jack into one of these ports.
Laptops and some more contemporary computers don’t have microphone ports, because they’re generally outfitted with internal microphones. It’s usually possible to plug into the headphone port on most computers, however, and adjust your sound settings later.

Review The Poll’s Results Variable Impedance This is a feature sometimes found on premium preamps that lets you adjust the electrical impedance of the preamp. The variable impedance feature gives you a range of settings, which may be useful for getting a different response out of your mics. How important is it? The bigger your mic collection, the more you may want this feature.
This is one reason that the connector was moved to the side on the follow-up radio series – the Jedi HT , MT , etc.
I also added a few pointers for constructing a tone-burst signal source and a receiver with microphone and fast peak meter for those of you, who would like to build some versatile acoustic test equipment. I must point out that steady-state frequency response curves – magnitude and phase – present only a limited view of a loudspeaker.
Hidden in them, and often not discernible to the eye, are further linear distortion data. These are better seen in shaped tone-burst measurements in the time domain. Also, non-linear distortion, which adds its own signature via new spectral components, that were not present in the original, must be made visible with single and multi-tone test signals.
Stored energy and non-linear distortion measurements were performed on a variety of drivers and influenced the selection made for the PHOENIX. The tweeter exhibits increased decay times above 12 kHz due to the trapped air between dome apex and plastic cup forming a mechanical spring-mass system. Removing the cup rapidly rolls off the response -8 dB at 20 kHz. Regardless, the metal dome tweeter was initially chosen for this design based on a slight listening preference. I have since gone back to the as the more accurate tweeter.
Frequency response must also be evaluated by how it might generate resonances, reverberation and reflections in the playback venue. And finally, the eye and the ear do not respond in the same way.

How to Connect an External Microphone to a Canon Camcorder
Share on Facebook Adding a microphone and headset to your office computer turns it into a virtual conference center. These devices make it possible for you to conduct remote business meetings and place phone calls if you have the appropriate software installed. In most cases, no drivers are needed; just plug the headset in and go. Before setting up the microphone and headset, decide whether you want to plug them into the front or back of the computer. Most models contain ports on both sides.
Step 1 Plug your headset into the round audio out port.
It is very sensitive if you use good RF power amplifier transistors, trimmers and coils.
Having a good audio configuration is critical for workers who often need to touch base with clients or other business professionals. Headsets allow users to both listen to and talk to others hands-free, but sometimes the mouthpieces attached to a headset aren’t of the best quality. You can connect the speakers on the headset to the computer but hook up a separate microphone to the PC to use instead of the headset’s mouthpiece. Plug the headphone connector on the headset to the green-colored jack on the back of the desktop PC or into the headphone jack on the right or left side of the laptop or netbook.
Connect the microphone to the pink-colored jack on the back of the desktop computer or into the mic jack on the right or left side of the laptop or netbook. You can follow the same instructions in Step 3 to set the default device; simply select the “Recording” tab instead. Some desktops come with front panel audio — often located under the optical drive — to which headsets, mics and other sound devices can be connected.
These sound jacks are not color-coded, however; instead, look for headphone and mic symbols next to the jacks to determine which port is which.

There are several different styles of microphone, ranging from simple stand microphones to professional headset microphones. Skype uses your system’s default microphone when recording sound to use over audio or video calls, though if you have multiple microphones you can change which microphone you want to use in the Skype audio settings.
You can also change your default microphone settings and volume in Windows settings. Determine the type of microphone you have. Your most basic microphone will fit into the 3.
The whip or straight-line antenna can be coiled, wound longitudinally or folded.
The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation. With 12 volt DC it will deliver 1 watt RF power. The most important parts of the oscillator are the transistor Q1 and the tuned circuit, which comprises the inductor Ll and the variable capacitor CV1.
When the battery is first connected, a brief surge of current flows from the collector to the emitter of Q1, causing an oscillating i. An oscillating voltage therefore appears at the junction of Ll and CV1. The frequency of the oscillation depends on the values of Ll and CV1, so that varying the value of CV1 tunes the oscillations to the exact frequency required. In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor.
Transmitter was mounted in metal enclosure and works extremely well. Frequency adjustment is accomplished with MV varactor diode and R7 10K potentiometer. The amplifier chip is an integrated circuit containing multiple transistor stages and all other parts conveniently within a single small package. Boosting your FM transmitter has never been easier and the output signal can also directly drive 2n or 2n transistors for 1W or 5W of RF output power.
It includes multi-level low pass filter and has a high conversion efficiency with strong Yi-wave suppression. With good antena expected transmission coverage is at least 15Km. FM Transmitters The proposed long range transmitter circuit really is very steady, harmonic free design which you can use with standard fm frequencies between 88 and MHz.
