How to Choose the Best Wireless PA System For Your Business?
A wireless PA system is a tool that can save you hundreds of dollars in wiring and trenching costs in situations where you need to install a PA system in a pre-existing building.
PA systems are very common in auditoriums, churches, malls, construction sites, schools, and many business establishments. The problem is that not all buildings were wired for system and retrofitting the building would be very costly and messy. Also, wiring gets old and may eventually stop working. This article will give you tips in choosing a wireless PA system that is affordable, easy to setup, and install.
Before you purchase your device, spend a few minutes of your time on studying these tips on how to choose the right one for your business.
1. Some wireless PA systems allow you to use your mobile two-way radios to send out voice messages to wireless speakers. These same two way radios can be used to reply to pages. That gives everyone full mobility.
2. If you have an existing wired PA system, you want to look for a system that lets you wirelessly interface to allow two-way radios to make pages over it.
3. Consider the size of your property. If you have a farm or a big hangar, or if you have a large property, make sure that you select a unit that has good range. You can get systems that can reach up to 2 miles away.
4. The loudspeaker of a wireless PA system usually is enough to cover up to 100 feet of space. But if your area is too noisy, or you just want to widen the coverage even more, you should choose a wireless PA system that allows you to install two loudspeakers on a single unit. It instantly doubles your coverage area without having to buy the complete set.
5. If there are obstacles that hinder your PA system from receiving signals, then you should also think about buying a unit that supports use of an external antenna that can instantly increase the receiving range of your unit.
6. Carefully plan where you are going to set up and install the unit. If you need to install a unit outside, look for a unit that has a weatherproof enclosure to protect it from the elements.
7. Since a wireless PA uses publicly available frequencies, you’ll want a unit that lets you program codes to restrict transmission of signals outside of your network. With this additional security feature, only radios with the right coding are allowed access.
8. If your business requires the installation of multiple wireless PA receivers, go for a unit that has zone paging. A zone paging feature allows you to send your message in different locations without having to use multiple frequencies. This is possible because of a distinctive paging code can be set up on each unit. With just a single frequency, you can send your message in just one area or you can send it to all units at once.
9. Feedback is the most common problem if the two-way radio is used in the same area as the PA system. So if you are always mobile and still want to broadcast via the PA system using your two-way radio, then check if the wireless PA system is able to record incoming messages and play them back over the loudspeaker only when the talk button is not being pressed by the announcer. There are commercial PA systems that allow you to record up to 20 seconds for playback after the message is received.
10. If you are going to use the system for emergency purposes, make sure you have one that has battery backup power so it can make pages even when the power is out.
A wireless PA system is a wise investment for any business that requires two-way communication to employees or customers. It is affordable and it can be quickly installed without tearing apart your property. Just follow these 10 simple tips and you are well on your way to buying the perfect wireless PA system for your business.
Paging Systems for Wireless Facility Communication
I don't need to tell you that PowerPoint and Apple's Keynote applications are probably your number one tool for presentations but be aware that what you see on your computer screen is not necessarily what you will see on a video or projection screen. Here are some important techniques and tips to consider when building your presentations for your next meeting, seminar or special event. Let your attendees get the most out of your hard work.
I have worked on countless programs that have used PowerPoint and Keynote as a major focal point for their sales meetings, award show celebrations and other events and I can't tell you how many times I've seen attendees struggle to see what they were invited there to see. Why loose your audience in the back of the room if you don't have to? One or more of them quite possibly could be your next company superstar but they missed your presentation because they simply couldn't see it and decided to play solitaire on their smart phone.
Lets add another layer to the necessity of reaching the attention of your attendees from the front row to the back row. With a phone or laptop, a wireless connection and a little social media at your attendee's fingertips, they may be posting in real time what a bore your presentation is. Not good. You can avoid much of this by following these guidelines when building your program for a projection screen in any venue or meeting space. You may have heard the phrase, "Presentation is everything." Never take this phrase for granted.
*Lets start with font / point size.
Here is a quick test you can try right now. Enter a sentence in your document in 6 different point sizes **(10, 12, 14, 16, 18, 20). Then simply move 4 feet back from your monitor or laptop screen. Without straining or squinting your eyes, which is the smallest point size that is easiest or most comfortable to read? I'm going take a shot and say you chose a point size of 14 or 16. Keep your font size at 14 or higher and you will be on the money every time. If you can't see your text content at this distance, neither can your audience or attendees viewing it on a projection screen regardless of screen size. We call this The 4 Foot Rule. It's a good idea to have satellite plasma screens in exceptionally large venues but you really want to keep your guests focused on the action on your stage.
Understanding Negative Space
For many years I've had discussions with event planners in need of a solution for making very architecturally busy meeting spaces or pre-themed environments disappear and turning giant, daunting spaces into intimate environments with the use of lighting. Understanding the concept of negative space is the key and the same applies to your screen presentations. Direct your viewers eyes where you want them. White backgrounds with black text is not recommended. The white space overpowers your text. You want your presentation to be dynamic. You want to hold the viewers attention. Use dark backgrounds with high contrast text, put borders around your photos and don't clutter your slides. An image with a single line of text or a handful of bullet points is the most effective use of your slide real estate. It draws the viewers eyes to the exact content you want them to see without distractions.
I'm going to cut to the chase here and say there are lots of web sites that discuss color schemes and the use of Primary, Secondary and Tertiary colors but for now, lets focus on what works on a projection screen. Color theory and colorimetry may be a topic for another day here. Take note, what you see here, the color saturation and contrast is not what you will see on a projection screen. **See link below for color image of this chart.
- Blue text will not work on dark or black backgrounds.
- Cyan text will work on dark or black backgrounds.
- Green text will not work on dark or black backgrounds.
- Yellow text will work well on dark or black backgrounds.
- Orange text will work on dark or black backgrounds.
- NEVER use red text on dark or black backgrounds.
- Pink text will work on dark or black backgrounds.
- White text will work best on dark or black backgrounds.
- Here is one last secret for squint proof, easy on the eyes presentation. If you have an extensive program that you can't break up with images or you must have slides containing a paragraph of text, go to your color picker and use a very very light shade of gray.
- Never use graphics that do not pertain to your message. The phrase "Less is more" in this respect is without a doubt, 100% true.
- Stick to one font set in your presentation. Sans Serif fonts are best for projection screens as Serif fonts are meant to be used with more text (Like a paragraph or book).
- Take a look at your favorite news program on TV and keep an eye out for how text is presented. Use it as a visual guideline. You will notice subtle movement such as swipes and fades, bulleted text and very minimal animation.
- Use or create custom key slide / key frame backgrounds or background images. Stay away from using the backgrounds included with the software. Everyone on EARTH has seen them already.
- Use the highest quality / resolution graphics and photos you can find. Don't acquire your images from the internet unless you know how to find high resolution images. Graphics and text decorations online are generally low resolution. Understanding some copyright law on using web images is a good idea as well.
Your presentation is not a stand alone document. If your slides are well crafted, your PowerPoint or Keynote document must require YOU, your narrative to have meaning. It is a tool to emphasize your key points, to add a bit of visual depth and possibly an emotional connection with your viewer to initiate action. It is a tool that ties a visual flow to your words, not the contrary. If it is more than this you have to much content on your screen. Put all of this together and you will have a successful presentation at your next event or meeting. Someone may even Tweet a nice comment about it back at the office.;-)
*The point sizes shown above will vary depending on your monitor or laptop screen resolution.

Wireless Internet Connections for Meeting Rooms
With the increasing use of cell phones and computer text messaging, an in-house paging system is still proven to be the fastest and most reliable way to alert and notify facility personnel. The main benefits of having on-site wireless paging systems are:
• Reliability - Poor RF signal reception is a common cell phone issue within many facilities, especially in heavy structured buildings and sub-level floors. Cell phone reception is as good as the closest cell tower, meaning dropped calls and poor reception can be a constant problem for any facility not near a cell tower. An onsite paging system uses a local radio transmitter designed to provide full RF coverage to an entire facility, which ensures reliable text messaging at any time.
• Speed -Text message transmission timing (the time it takes a message to reach its destination) is fully dependant on the service provider and the communication load, explaining why text messages can take several minutes to be delivered. With an on-site paging system, a message is delivered within 2-3 seconds at all times, regardless if it was sent to a single pager or a large group of pagers.
• Safety - Cell phones are a great connectivity tool, but they present a few unacceptable safety and privacy issues. All cell phone activities are tracked and documented by their service providers - information that can find its way into the wrong hands. Features such as built-in cameras, GPS and microphones present great risks for private meetings, information-sensitive work, secured areas, etc. Having an in-house paging system ensures that you are in control over all of your private information. Another safety issue is cell phone radiation, especially in indoor locations with poor reception. Low reception causes cell phones to use their maximum power to stay in touch with the local cell tower, creating more radiation and a larger threat to the user. An in-house paging system functions as a one-way communication link. Since the pagers are only receiving data, they produce no radiation.
• Control - Using an in-house paging system also means having complete control over your urgent messaging needs, instead of placing an outside company in charge. Rather than paying monthly cell phone charges or renting pagers from an outside provider, an in-house paging system carries no additional costs after the initial system purchase.
Today's modern paging systems offer much more than just text messaging. These systems can control products such as alphanumeric LED displays for public areas, wireless speakers for PA voice messaging and wireless strobe lights for special visual notifications. When used together, these products can improve safety and communication in any facility.
