RC4Magic Wireless DMX and Dimming employs low-power direct sequence spread-spectrum (DSSS) digital RF in the 2.4GHz ISM (Industrial/Scientific/Medical) band. One RC4Magic system consumes 1/15th of the available spectrum in that band. (Compare this with a WiFi network consuming up to 1/3rd of the band, or various frequency hopping spread-spectrum (FHSS) wireless-dmx systems that hop through 100% of the band.)
When an RC4Magic transmitter powers up, it scans the band and transmits in the quietest region it can find. If spectrum usage in your vicinity has changed, simply power down and back up — our transmitter takes care of the rest. Receivers automatically follow the transmitter when you do this (a process that can take up to 30 seconds).
When we demonstrate RC4 products at tradeshows, our system operates along side every other wireless product available to you in the entertainment industry. Wireless mics, intercoms, etc., are all up and running on display. If a problem were going to arise, this is where it would be: it’s far worse than any real installation, where specific brands and systems have been selected and channel selections have been managed (no such management takes place at tradeshows — it’s every company for themselves). Not only do RC4 systems function flawlessly, we do not cause problems for other exhibitors.
The shows we exhibit in are not small. We participate every year in USITT Stage Expo, and almost every year in LDI. We have also appeared several times at ABTT Theatre Show in London, England.
Now that RC4Magic has been on the market for several years, we also have real-world evidence. Our customers do not suffer from interference problems. See our customer list — there is probably someone there you know. Ask them about interference.
With thousands of productions using RC4Magic every day, including numerous shows by Cirque du Soleil, Disney Theatrical, and attractions at Disneyland, Sea World, and elsewhere, interference issues would quickly be brought to our attention if they existed. We’re proud to say there are none.
RC4Magic works. It is impossible to claim you will NEVER suffer a problem. But it is very very very unlikely that you will.
