Worldwide, operating 2.4GHz wireless systems face no local restrictions, licensing or frequency coordination issues, but there are many potential sources of interference in this public use radio band. Everything from WIFI, cordless phones, baby monitors, garage door openers and others use the 2.4GHz band.
Audio-Technica’s System 10 Digital wireless builds immunity to all interference by way of three, redundant layers of sophisticated digital technology that are completely invisible to the user.
Firstly, the Frequency Diversity layer sends the signal from the transmitter on two dynamically allocated frequencies at the same time—the clearest channel is always used. Secondly, the Time Diversity layer shifts signals very slightly in time (unnoticeable to the user) to multiple time slots in the receiver. This feature maximizes immunity from multipath distortion that has always plagued wireless systems. Finally, Space Diversity uses two antennas on both the transmitters and receivers to maximize signal integrity—usually you see only two antennas on the receivers and this feature all but guarantees solid radio signals 100 percent of the time.
System 10 includes the ATW-R1100 single-channel receiver and either a body-pack transmitter or handheld microphone/transmitter. The ATW-R1100 is a diversity digital receiver offering volume control along with an audio peak meter and a successful pairing indicator. Up to eight channels of AT’s System 10 can be used at the same time at the same venue.
Multiple system configurations are available, with handheld vocal microphone/transmitters and UniPak® body-pack transmitters designed for use with lavaliere, head worn and instrument microphones as well as electric guitars. Pricing starts at $489 MSRP. See http://audio-technica.com.
