![]() ![]() These systems tend to be very user-friendly and cost effective. It is also possible for the audio to transmit around corners, through walls and other obstructions with a great deal of ease. This range falls between 169 – 172 MHz, also known as “traveling frequencies.” This means that within the U.S., you can use these frequencies in many cities across most of the country and run a very low risk of interference from other VHF transmissions.īecause of the length of VHF waveforms, the transmission signal can travel long distances without the need for direct line-of-sight between the transmitter and receiver. ![]() Although most of this frequency range is allocated for other usage, there are a few frequencies open for unlicensed wireless microphone system operation. VHF stands for “very high frequency” and occupies the range of 25 – 300 MHz in the wireless spectrum. Trying to parse out all of this high-tech nomenclature is enough to drive one mad! But before the madness overcomes you and you feel the sudden urge to hunt down and beat up Dan Rather, keep on reading In this article we’ll try to make some sense of the different wireless microphone technologies available in today’s U.S. The operating frequency set of a wireless microphone influences many other considerations, such as operating range, cost, ease-of-use, interference risk and licensing. There are so many systems on the market, operating in various frequency ranges, it can get very confusing as to which system is going to work best and why. What’s not so obvious, though, is choosing the right wireless microphone for your production. ![]() Plus, the wireless mic is always in close proximity to your speaking subject, giving you the best possible signal-to-background-noise ratio. The advantages of using a wireless microphone to capture professional audio is obvious: it gives all members of the production the ability to move around freely without the encumbrance of wires. ![]() There are many audio capture technologies at the disposal of today’s filmmakers, not least of which is the wireless microphone. ![]()
