Shure to discontinue 600MHz Wireless Systems
It's time to stop buying 600MHz wireless systems in most markets. In reaction to impending auctions of broadband wireless spectrum, Shure announced today the discontinuation select frequency bands L4 in FP and SLX Wireless Systems and M1 in ULX-S Wireless Systems. L4 ranges from 638.000-662.000 MHz and M1 ranges from 662-698 MHz, in a move that appears to eliminate its devices in most of the 600Mhz range.
This is the first product discontinuation from any of the major wireless microphone manufacturers, but expect to continue to see similar notices from other manufacturers, as each anticipates what the FCC will do next. With what we understand of the rules established by the FCC with respect to notification and auctions, we have at least 42 months before the 600MHz wireless spectrum will become unavailable (similar to changes related to the 700MHz spectrum that occurred in 2010).
Don't sweat it a lot if you have existing 600MHz systems, but in most parts of the country, it's probably a good idea to look to other parts of the radio spectrum as places to invest your wireless dollars. As you have questions, please watch this page and call us anytime that we can be helpful.
Five Things Every Audio Pro Should Know How to Do
by Alex Milne
These five common concepts and skills separate the skilled audio professional from the beginner.
In our opinion, they are essential to a full understanding and mastery of audio systems.
They are evenly divided between simple overarching concepts that can be applied to any project, and practical skills that can be used to save time and money, or engineer elegant solutions to problems that emerge in the field.
1. How to coil cables right.
Many types of audio-visual cables contain twisted wires inside a sheath. This gives them a natural coil that can easily be disturbed by improper coiling. The wires become tangled inside the sheath, and the natural coil ruined, shortening the cable’s life. Other types of cable, like coaxial cable, have no natural coil. They still benefit from proper handling, which avoids knots, tangles, and crushed insulators.
The right way to coil a cable is by using the “over-under” method, which is better shown than explained. This video from the London School of Sound does an excellent job showing how to coil cables using the over-under technique.
2. How to build cables from scratch.
Many audio cable connector schemes follow a basic blueprint: positive, negative, ground. If you know how to strip and make a connection from raw cable, you can build cables to custom lengths and salvage good portions of damaged cable - which is incredibly useful. Although the specific procedure for soldering a connector varies by type, a soldering station (iron, sponge, solder, helping hands), box cutter, and pliers with wire snips are often all that is required to solder the more common types, like XLR, ¼”, and 3.5mm, during an emergency repair.

Five Wireless Microphone Mistakes That Are as Common as They Are Avoidable
by Alex Milne
They’ve happened to the best of us. After paging through stacks of manuals, phoning and perhaps yelling at manufacturer technical support lines, and checking and re-checking dozens of options on menu screens, we discover the cause of our wireless microphone malfunction is something so breathtaking simply, so glaringly obvious, that we can’t believe we didn’t think of it in the first place.
The following five mistakes are blunders shared by inexperienced and experienced audio pros alike. Do not be ashamed.
1. Dead Battery
The lifeblood of the wireless microphone transmitter, the battery, is a fickle creature.
The useable life of a battery is influenced by a number of factors, which makes it hard to pin down just how many hours you’ll get out of a microphone. The type of battery in use, the brand, the temperature, and - the oft-ignored curveball - the transmitter power (20 mW vs 50 mW, etc), can all dramatically change how long your handheld perseveres.
Some people play the russian roulette game of guessing how much juice they’ve got left on a case by case basis. Others invest in a battery tester or multimeter. The most paranoid users (and the wisest) don’t let a mic go up on stage without fresh batteries. This results in a lot of half-used batteries that go in the battery recycling bin, but it is a heck of a lot better than a mic going dead. You can purchase batteries by the case from your favorite audiovisual retailer. If you do any kind of mission critical work, we encourage you to do the same.
17 seconds to better audio
Listen to for 17 seconds to hear the difference that 17% can make.
Problem: The main worship facility at South Delta Baptist Church of Delta, British Columbia seats approximately 1600 people with both main floor and in the upper balcony. Due to a 4 second reverb/decay time, a large percentage of the congregation was challenged in hearing the message due to a lack of vocal intelligibility - caused by excessive reverberation and echo.
Solution: Primacoustic Broadway panels were placed on only 17% of the wall surface and spread evenly throughout the sanctuary. Since the style of worship incorporates amplified instruments, careful attention was paid to the stage area to control reflections from vocal monitors, guitar amplifiers and drums.
As a result, reverberation was decreased from 4 seconds to just over 1 second, greatly improving intelligibility and enhancing the worship experience for everyone.
