1. Care and Use of your Group.X Evo and Group.X Evo lite Portable PA
Thank you for purchasing the the only portable PA systems featuring the Evo True Wireless
transmitter. This Patent Pending PLL synthesized wireless microphone system operates in an FCC
approved UHF band frequency with 16 selectable channels. Please read this instruction manual
carefully before operating your system. This manual covers the function and operation of the wireless
microphone system and portable PA system.
Some things to remember:
While the Evo headset is water and sweat resistant, the portable PA units are not. They should not
be stored in humid environments (around the pool, for example).
Not all CDs are created equal. No CD player can guarantee 100% compatibility 100% of the time
with 100% of the CDs available. You may find CDs that will play reliably at home, but not on your
portable PA. You may find CDs that will play reliably on your portable PA that will not play at home.
If you are playing CDs that you burned yourself, make sure you start with good quality CDs, and
burn them with high quality settings.
If your unit has wheels, remember that they are there as a convenience and that it is not an off-road
vehicle. Don't slam through doorways, over bumps or down stairs. Even though the internals of
your PA are designed for durability, use good judgment and caution – protect your investment.
Do not spill liquid on the Group.X and do not drop either unit.
If you have the
Group.X Evo Lite
, be certain to charge your portable PA every two weeks. This
helps to maintain and lengthen the service life of your battery. Failure to do this may damage the
battery.
After charging or setting the channel on your headset, always close the covers to maintain moisture
resistance.
For heavy use installs, periodically apply silicone grease (Part No. SP-SG-10 or SP-SG-5) to the
charging connector of your Evo headset. You only need a very slight film, and only inside the barrel
of the headset connector. Just put a small amount – the size of a BB - on the tip of the silver
charging jack and insert as normal to charge. Too much will just be messy.
Do not place the units near heat sources such as radiators, amplifiers, or etc.
Do not store in direct sunlight, extremely dusty or humid conditions.
2. Wireless Notes
Before setting up, make sure that the transmitter and receiver are tuned to the same frequency.
Do not use two transmitters tuned to the same frequency. You may, however, use multiple PA
systems with receivers tuned to the same channel. This is particularly effective if you want to
spread the sound around the room more evenly. You may have one PA unit addressing the first few
rows of the class, and another PA unit in the middle (aimed away from the instructor) to cover the
back of the class.
Always operate your system with a fully charged battery.
While checking sound, move the transmitter around the area where you use the system to look for
dead spots (loss of signal). If you find any dead spots, change the receiver position. If it does not
work, avoid such places.
To help avoid interference, do not put the receiver too near substantial metal or reflective objects
and avoid obstructions between transmitter and receiver.
Avoid the interference from TV, radio, other wireless appliances and etc..
Wireless systems depend on fully charged batteries. Low batteries will seriously degrade
performance. Be certain to allow charge time prior to use.
Be certain that the Group.X portable PA is exposed and in 'line of sight' with the transmitter.
