Conferencing systems in use FAQ

v1. I can use two microphones do
the same frequency can not be accustom. Wireless transmission is not in the air, For instance, two FM radio to send signals on the same frequency, this location is not the circumstance. Because it would lead to muddle, resulting in audio deformation. All in entire, each wireless transmitter receivers should have a divide its peerless frequency.
2. the distinction in the frequency of the wireless microphone in order to avert interference?
It depends on the circumstances, merely at fewest 4MHz. Here we can not explicitly question this answer, because it involves complicated calculations. In general, the cheaper the frequency of the wireless system needs a big breach between the recipient design because they are simple,Cheap Gucci Shoes, fewer choices. This limits the number of channels of its compatible. The higher the amount system, the filter is good, the distance between the recent channel, compatible with a corresponding boost in the channel. If we mention, If you need, amuse adjoin the manufacturer or dealer, they will assist you calculate. Most manufacturers have calculated Shure characteristics of each wireless compatible frequencies, so you do not own these difficult algebraic calculations.
3.UHF better than VHF, right?
because wireless microphone both of these two frequencies the values, has its own failings. This namely a orchestra of users, frequency of physical specifics, and adapt the limits of the band's decision.
The following are several aspects of UHF than VHF:
· UHF band VHF band is not
· amenable UHF frequencies using a wider range.
· UHF functions to invest more compatible system. [Eg, Shure LX and SC (VHF band) system is compatible only provide 12 outlets, meantime Shure's UHF-band system provides more than 100 compatible channels. ]
· UHF system power output than VHF, frequency shift wider dynamic scope and better semaphore to noise percentage is better than VHF.
VHF than UHF in several aspects:
1. VHF system cheaper.
2. VHF transfer power in a specified, the launch larger.
3. VHF signal is transmitted,Gucci Shoes, even via non-metallic materials,Womens Gucci Tall Boots, for well. VHF's longer wavelength, can not lightly be absorbed by the body.
4.UHF system tin be compatible with the VHF system to use it?
can, even if the number of VHF systems for most compatibility, it can too be compatible with UHF. (But can not sink the current UHF VHF `VHF antenna splitter or delivery amplifier VHF antenna joined.)

5. projector conservation
the process of using the projector, the most major publish is to retain agreeable heat exhaustion. Projector has two power switches, a soft switch (POWER key), the additional is a hard switch (power switch SWITCH). After using the projector,Mens Gucci Moccasins, have to press the soft-switch (POWER button) Turn off the projector, in truth, at this period the end of the projector does not truly go in the side of the cooling flare still scampering, for the projector is radiated at work large heat out, so contractors have devised three - 5 minutes of cooling process. If you rotate off the projector at this period so the heat can not be discharged among, alternatively the bulb will flame out the LCD panel. After turning on the fan stopped, etc., can rotate off hard switching. Generally use the projector in a row 4 or five hours afterward, what should be allowed to break out. This extends the life of the lamp and LCD panels. Avoid showing impact when the projector.
6. projector screen colors and display the color appears different
screen appears when the projector is not the same color and the color display, VGA wire could not elect out a good or internal connecting the root of a color line, and different may burn out the LCD panel.
7. projector hurl some characters displayed in the screen when the projector is not fully
provided in some characters above the shade exhibit is not complete, there may be some resolution of the projector is not enough,Gucci Shoes Sale, symbol graphics display is not complete, can dwindle the resolution to discern the calculator will no be displayed entirely, if it were not for, that there was a 3 liquid crystal movie has burnt out.
8. projector arise yellow or dark color is not full
If the projector appears dark yellow, the color is not brilliant time. Lamp life may have to re-change a light bulb (It should be noted that even afterward the change to reset the lamp method time, or a new lamp is effortless to count the time by old age.
