Setting up a wireless microphone system can get complex if you want to practice it correctly. With the contempo FCC auction of the 600 MHz (Megahertz) ring of frequencies, users of wireless microphones all across the state are being forced to reconfigure their wireless systems. The age of having the freedom to exit huge gaps between your wireless microphone frequencies is over as the amount of available frequencies has been drastically reduced. Considering of this, it is of import to buy the right equipment and make the correct choices when setting up your new organisation.

How to Prepare a Wireless Microphone Organisation

How do Wireless Microphones Work?

Unlike all of the other popular microphones in the earth, wireless microphones send radio waves but like your FM radio to ship sound signal wirelessly from a microphone to a wireless receiver. Virtually all wireless communications, including LAN, Bluetooth, cellphones and television broadcasts utilize radio waves. Radio waves are measured in frequency with the lowest frequency waves having the ability to travel the furthest and the highest frequency waves the shortest.

Wireless microphones operate in the UHF, or "Ultra High Frequency" range between about 300 and 1000 MHz. This range of frequencies is governed by the FCC, the Federal Communications Commission, where they designate sub-ranges of the UHF range for various functions. For instance, the 225-420 MHz is reserved for regime use, while the 849-851 MHz bands are reserved for commercial aviation systems.

The FCC designates the certain MHz bands for unlicensed use of wireless microphones. That beingness said, these bands of frequencies are not reserved or kept open for the employ of wireless microphones. This space for unlicensed activeness is often a gratis-for-all of point. As such, when yous're setting upward your wireless microphones, it is not uncommon to discover interference across several of your wireless channels. There are however steps yous tin can accept to make sure your organisation can differentiate interference from your desired signal. This guide should assistance you lot to make sure that happens.

Choosing the Correct Wireless Microphone

There are a lot of affordable options out there for wireless handheld or headset microphones and receivers. You're obviously going to desire to make certain that you lot're buying a quality microphone, but for the purposes of this guide you're going to desire to examine the receiver get-go. The ideal receiver touts the more advanced "True Diverseness" applied science as well as outputs for coaxial cables that allow you to connect your receivers to an external attend (nosotros'll get to that afterward).

True Multifariousness receivers accept ii carve up antennas running on ii contained receiver sections. The antennas on contrary ends of the receiver and the receiver constantly compares the signal between the two antennas and captures whichever point is the strongest. This provides a much more than stable connection as the odds of having both antennas driblet signal simultaneously is very low. You'll also want to brand sure that you're purchasing a system where the settings can be adjusted easily on both the handheld microphone or trunk pack as well every bit the receiver rather than merely on the receiver.

Wireless microphone systems come up in a variety of mic and receiver types.

Both Shure and Sennheiser offer some of the highest engineering in terms of microphone quality and receiver reliability. Although we did provide many great options in our 10 best wireless microphones guide that's gained a lot of traffic through out the years, I lean more than towards the Sennheiser models as I find them easier to prepare up.

This Sennheiser EW 100-953 G3 system comes with a very high quality dynamic microphone and a receiver that checks all the boxes in terms of features, ease of use, and reception forcefulness. Here is the handsfree version of the same system.

Choosing the Right Wireless Frequency

Here is where setting upwardly a wireless microphone organisation start to go tricky, and some mistakes may occur. Some receivers have a built-in scanner that volition automatically scan through the frequencies and give you the ones that have the to the lowest degree interference. This is similar to the manner your sometime tv tuner used to be able to browse for available channels on setup. The Sennheiser system above, and many like it, offering instant data on noise coming across that frequency as you scan across your channels. The two bars on the left of the receivers display offer you lot information signal strength and book.

As y'all scroll through each frequency, cease for a moment and observe those two confined. The channels with the least corporeality of activity are the channels that will exist the all-time for setting your microphone. Once yous accept your channel set on the receiver, yous can quickly sync the receiver with your microphone by using the quick sync office that comes with the Sennheiser model. If your model does not have a quick sync function, you'll simply melody your microphone to the same frequency as your receiver.

Finding the right frequency can be catchy, but effective when taken the fourth dimension to do so (Source; YouTube.com).

At present but because you have a signal does not hateful you're washed. Brand sure you're scanning and setting your frequencies in the same infinite where y'all'll be using the microphone. Just because your wireless mic continued flawlessly in your living room does non mean it will work as well when you take your arrangement with you to the location of your gig. Ideally, this process of scanning and selecting frequencies should take identify at every new location.

Now many microphones and receivers come up with the power to quickly change betwixt preset channels similar to the manner you lot tin save 6 radio stations on your automobile radio. If you're constantly using your wireless system in the same spaces, you tin can observe frequencies that piece of work, save them as presets, and switch quickly and easily after the first scan at each location.

Strengthening Your Wireless Microphone Signal

Retrieve when we talked about those external antennas? For annihilation larger than a 50 foot gap between the microphone and the receiver, an "elephant ear" fashion external antenna is going to be an accented must-have. Yous can use any brand of antenna with whatsoever make of microphone, equally long as the frequency range on the antenna is the same equally the frequency range of your microphones. The good news is, you can utilise upwardly to twelve microphones with one pair of antenna!

If you lot're following this guide and using a true variety receiver, you're going to demand two antennas in social club to continue to reap the benefits of true multifariousness technology. To continue things consequent, I'll recommend a pair of these Sennheiser A2003-UHG Directional Antennas (these are ordered one at a fourth dimension so make sure to accept two in your cart at check out).

These antennas conveniently screw into the top of a microphone stand similar a microphone prune. You want to have the face up of the antenna aimed at the general direction where your microphones will be. You can plug a pair of these antennas straight into your microphone receiver using these coaxial cables. If you're going to connect multiple receivers to your antennas, things outset to get a little disruptive.

There are ii ways to plug multiple receivers into one antenna. You can either utilize passive splitters or agile splitters. Passive splitters are exactly what they audio similar, splitters that passively split the signal without whatsoever distension. When using passive splitters, you'll actually lose about 6 decibels of signal for each splitter. If you're only splitting it once or maybe fifty-fifty twice, you can go by with this method. It is far less expensive than using active splitters.

Agile splinters allow you lot to split the signal without any loss of sound. This Sennheiser ASA1 Splitter will work perfectly with the equipment listed above. It even comes with viii coax cables! This unit will too power your receivers so you'll no longer need to use Air conditioning adapters to power each individual receiver, freeing upward lots of space on your power conditioner or ability strip.

Each splitter comes with two antenna slots (1 for each antenna in the true diversity arrangement) and 8 slots for receivers. You'll be connecting 2 cables to each receiver, one for each antenna signal, so this allows you lot to connect 4 receivers to two antenna. Now I know what you're thinking… Yes I did mention earlier that you tin connect upwards to twelve receivers to 1 pair of microphones. This will be costly, but can be achieved by connecting four splitters to one master splitter instead of 4 receivers to one main splitter. Each splitter can and so exist connected to four receivers, assuasive you lot to connect up to xvi receivers to 1 pair of antennas. This is about as many receivers as yous'll want to try to connect to 1 pair of antennas.

Setting upward a wireless microphone organization can exist costly and confusing only like most other audio endeavors, it is worth it to spend more money and do it right the start fourth dimension rather than endeavour to repair something that was done haphazardly down the road.
