LightSPEED Technologies Inc. launches the Delta X Series Wireless Sound Solutions. Three different models, the Delta X12, Delta X10 and Delta X6, set up in less than a minute and combine portability and advanced technical features with user-friendly controls to communicate with ease to groups covering more than 250,000 square feet. All three models accommodate, one or two optional 100-channel, frequency-agile, UHF wireless microphone systems that automatically select the best frequencies to use via the "Clear Channel Scan" feature. The efficient design allows units to run self-powered for up to 12 hours on internal battery power for venues that are not wired for electricity.
