TIPS AND BEST PRACTICES FOR DIGITAL WIRELESS MIC/INSTRUMENT SYSTEM OPERATION
Here are some tips, tricks and best practices to keep in mind that will enable you to get the most reliable, real-world
performance from your DMS100/DMS300 wireless systems:
Ideally, you should always maintain line-of-sight between the transmitter and receiver within the operating range
of the system whenever possible. In actual use in various wireless environments and conditions, actual operating
range may be higher (actually much higher) or lower.
The human body itself acts as a shield that blocks wireless energy transmission. So it is important to make sure that
bodypack transmitters are not covered or blocked (again, think line of sight).
The DMS300 does not support the use of remote antenna cables.
There a number of potential barriers that may prevent you from getting the best wireless operation/results in real
world settings including solid walls, metal objects, crowds of people and other wireless devices/systems in a given
environment.
o Do not place DMS100/DMS300 receivers next to large, reflective metal objects or walls that can absorb
wireless systems and prevent signals from being received. If you plan to rackmount your wireless receivers,
use wood racks rather than solid metal racks that can adversely affect wireless performance.
o Metal jewelry may also limit operating range or performance as it can act as an antenna and disrupt the
transmission of the wireless device. The larger the piece of metal is or the closer it is to the transmitter, the
more likely this issue may occur.
o Wireless environments range from being open, clear spaces to very dense with lots of wireless activity all
around. While not always possible, try to keep radio/radiation sources as far away from the receiver as
possible. This includes any number of wireless sources/devices that operate on WLAN or Bluetooth. Always
be consciously aware of your wireless surroundings in order to mitigate possible issues in advance.
o As mentioned earlier, a group of people placed in between the transmitter and receiver can block wireless
signals. So consider evaluating the placement of the receiver and keep antennas are as close to the
transmitters as possible while maintaining line of sight.
After removing the battery cover from the bodypack transmitter, you will see an input sensitivity/trim pot that
enables you to adjust the input signal depending on the instrument or microphone connected to it. Use the tab on
the battery cover/door as a flat-head screwdriver to adjust the trim pot position up or down and then monitor the
audio level. While playing (or singing) at your typical level, set the trim pot to an optimum position where you hear
the maximum audio level output before the audio level overloads/clips or it sounds distorted.
AA alkaline batteries are the recommended type for use with DMS systems. Check the battery level indicators on
the transmitter prior to each use to assure that you will have sufficient power need to make it through the
event/meeting/performance. You can also monitor battery levels from the receiver side as well. Weak batteries can
lower signal strength and operating range. So make sure to keep quality AA alkaline batteries on hand at all times.
