Setting Up A UHF Wireless System
cheap tiffany jewelryWhat
is a wireless system? In essence it's comprised of a radio transmitter
and receiver. There are many transmitters depending on what you'll be
using it for. This article will hopefully help you on your way to
setting up a UHF system.
1. Transmitters:
The most often used is the transmitter that's inside of the hand-held mic.
The alternate kind of transmitter uses a body-pack where you can plug in different pieces of gear:
Fixed to a piece of clothing, or on a lanyard the lapel mic is hardly noticable.
The next is the headset microphone which is often used in a live performance where the singer is unencumbered and can move around freely.
The 3rd is for, say, a guitar or some other instrument that uses a phone cable.tiffany necklace white gold
2. Receivers:
A receiver is a lot like the radio at home or in your car. It captures a signal and sends to it, which allows you to listen to what that signal is. in essence the receiver takes the radio waves from the transmitter source receives it and demodulates it (turns it into electronic form) so we can plug whatever device we want into it.
It will probably a an amplifier of some sort or a mixer. Body pack systems can also work very well on video cameras.
3. Receiver Antennas:
The UHF system (ultra high frequency) will have two antennas which are connected to two electronic circuits with a switcher between them. Since the antennas are not used both at the same time, the auto-switch chooses the one that gets the most robust signal.
You'll need to place the 2 antennas at a 90 degree angle to eachother (45 degrees from the ground). with this arrangement you'll get the best performance results that you can.tiffany rings
It's desirable that nothing blocks the waves between the receiver antennas and transmitter. Most wireless systems can receive and transmit signals through dense objects but will work better in open spaces. It might take some trial and error to put the receiver in a place where it will pick up the transmitter, especially when using a body pack. You can get a remote antenna set, but that's beyond the scope of this article.
4. Scanning Frequencies:
UHF systems generally can operate at different radio frequencies above normal transmissions such as TV or cell-phones. Prior to setting up the scanner on the receiver, switch off the transmitter. Utilize the screen on the receiver to choose the scan selection. This will probably take a while for the receiver to settle on the available channels but once it does you can choose them from the displayed banks.tiffany bracelet
After this you'll be able to choose the frequency channel. (in the receiver display.) Now turn the transmitter from off to on and find the same channel as the receiver.
5. Varying the Attenuation on the Transmitter:
This is another name for gain or volume. The transmitter will have options for altering the volume to get the the right level of signal. Too high and it could end up sounding distorted; too soft and it will be hard to hear.
6. Setting the Receiver Output:
Step 6 is the last concern in setting up your wireless system. Much like the sensitivity for your transmitter this step determines the final signal sent to the amplifier or mixer. Be in contact with the audio guy and he will tell you when the output is right. That's about it on this matter. Happy music making!tiffany earrings
