Audio Engineering Webinar For Houses Of Worship (HOW)
A free Audio Engineering webinar organized by Shure and Electronics & Engineering Pte. Ltd walks through current topics relevant for Houses of Worship (HOW) applications.
Specially designed for Houses of Worship, we have invited Robert Soo as our key speaker for this webinar. Robert Soo has been in the industry since the '80s. A proficient worship leader, he had served as both Technical Director and Worship Pastor. He then moved on to developing professional microphones, audio devices & communication systems for an American MNC. In 2011, he started Cogent Acoustics, a consultancy firm that provides AV & Acoustics Systems Design and Training Services.
Incorporating the Shure Digital Revolution program, trade in your existing wireless systems for a rebate with the purchase of any participating Shure Digital Wireless Solution.
Topics for the webinar will include:
IMDA Regulations
Wireless Systems
Proper Placement/Positioning
Antenna Distribution and Combiner Systems
Batteries for Wireless Systems

Webinar Q&A
Robert Soo, Cogent Acoustics:
Placing receivers in a rack (a) obstructs the RF signal, (b) causes bunching of antennas and (c) not allow the antennas to be oriented properly. A recipe for causing RF dropouts. Thus for optimum RF performance, it would be best to implement an antenna distribution system and to properly position the remote antennas for an obstruction free path to the transmitters. Remember to choose the right type of antennas for your applications.
Robert Soo, Cogent Acoustics:
For most wireless systems, I believe including Shure, has little to no issues working with 1.2V rechargeable batteries. However, I have come across some wireless manufacturers that advises their customers not to. I guess it really depends on the specific wireless system design as well as the microphone element used, as some require the full voltage swing for optimized operations. Please check with the technical support for the wireless system you're using to be sure (no pun intended!).
Robert Soo, Cogent Acoustics:
Technically, yes you can. But you have to properly coordinate the operating frequencies for both the analog and digital systems, as each will occupy blocks of space differently in the spectrum. When unsure or if you encounter interferences between systems, please consult their technical support. I would also advice to mix systems from the same manufacturer so the technical support can better understand and support your systems.
Robert Soo, Cogent Acoustics:
There are quite a few brands of good quality rechargeable batteries out there, and Eneloop seems quite well reviewed by many users. Do Google for reviews, and I'm sure you'll find the right ones for your use. But be reminded that any rechargeable battery is only as good as how well they're taken care of in order to ensure their operating long life.
To manage IEM systems with wireless workbench, PSM1000 systems is recommended as there are ethernet port to manage & coordinate the systems real time.
Robert Soo, Cogent Acoustics:
Check out the websites at NEA as well as ALBA E-Waste Singapore. There are some advise on where and how you can dispose of your batteries.
Shure South Asia Limited:
Yes, Wifi does interfere with the 2.4Ghz range. We will recommend UHF microphones in larger venues.
Robert Soo, Cogent Acoustics:
As mentioned above, it affects mainly the 2.4GHz systems, but it doesn't mean it will always interfere with them, as it depends on a number of conditions such as proximity, the quantity and type of wifi devices in operation, and the amount of RF traffic at the specific time. Sometimes we get lucky and it works without issues, but the real risks are always there.
Shure South Asia Limited:
1.9Ghz are legal in some countries, it is legal in Singapore. We have our Microflex Wireless running on that frequency.

Robert Soo, Cogent Acoustics:
Unfortunately the RFI from LED video walls are random, and different LED video walls emit different patterns, so it's difficult to specify what recommended frequencies will work for interference free operations. If needed, a scan can be done to determine the nature of the RFI. If not, it's good to keep a good distance between the wireless systems and the LED video walls.
Robert Soo, Cogent Acoustics:
My understanding of rechargeable 9V batteries is that the Ni-MH version do not provide anywhere close to 9V but rather more like 7.2V, and they also have very small charge capacity, much less than the single use type. If needed, go for the Li-ion rechargeable 9V as they practically have about the same capacity as the non-rechargeable type. But do note, some Li-ion 9V rechargeable are slightly larger in dimensions than the standard 9V and it may not fit properly into your device, so please check first before buying.
Shure South Asia Limited:
The best is to use an Antenna distribution System such as our UA844+SWB and UA874 directional antenna in the portable rack to ensure good RF coverage.
Robert Soo, Cogent Acoustics:
In any application, it is always advised not to use batteries that are at different charge levels. It will not affect the lifespan of the mics but it will definitely affect the operational duration.
Shure South Asia Limited:
We highly suggest you to bring to our local distributor service center to help you on this issue.
You may contact E&E Services.
Shure South Asia Limited:
For general scanning and displaying the RF environment, we have a device called Shure AXT600 spectrum scanner can provide precise information for allocating the best available frequencies to any number of wireless channels UHF spectrum (470-952) MHz. Please reach out to Shure team/distributor to understand more on your requirement.
Shure South Asia Limited:
Yes there are. For general scanning and displaying the RF environment, we have a device called Shure AXT600 spectrum scanner can provide precise information for allocating the best available frequencies to any number of wireless channels UHF spectrum (470-952) MHz.
Shure South Asia Limited:
Not recommended as if there are technical issues occurred on the systems, it may be difficult to troubleshoot the root cause of the issue. We reckon that Shure antenna distribution systems should be utilized with Shure receivers.
Robert Soo, Cogent Acoustics:
As the RF regulation often gets updated in the various ASEAN countries, it is difficult to say which would be accepted at a certain point in time. The last I heard about Thailand's regulation is that they allowed several small pocket's of frequencies between 700MHz to 800MHz, but my information could be obsolete by now. I believe Malaysia's regulation is pretty similar to that of Singapore's. But all these needs to be confirmed.
Shure South Asia Limited:
As for now, there are no plan for Rebate Program 2022. Please reach out to Shure team or local distributor as we can arrange a session of planning & discussion to cater to your budgeting plan.
Shure South Asia Limited:
For SBC200, it does not have auto-cut protection. We have new chargers called SBC220 to charge SB900 & has storage mode if you have requirement to store the batteries more than 8 days. Each battery will be charged or discharged to 3.8 volts, which is ideal for long-term storage. Another advantage of SBC220 it is compatible with Wireless Workbench that provides detailed information for batteries currently docked in the charger. You can also view battery error notifications and change the charger's network settings.

Shure South Asia Limited:
It is ok to stack them, but the antenna distribution should be in place to avoid RF phase cancellation which causes potential drop outs.
Robert Soo, Cogent Acoustics:
If implementing an antenna distribution system is really not possible (at least in the short run), then you must space the receivers apart, with at least 1/4 wavelength distance in between (>150mm). And remember to ensure there is always obstructed paths between the transmitters and receivers.
No news on that yet. We are equally excited as you!
