The ATW-1101/H92 System 10 from Audio-Technica is a digital wireless headworn microphone solution for lecturers and similar applications that require articulate vocal reproduction. The set includes the ATW-R1100 digital receiver, the ATW-T1001 UniPak pocket transmitter and the black PRO 92cW headworn microphone. It uses 24-bit, 48 kHz digital audio and operates free from TV interference in the 2.4 GHz frequency range. Built for expandability, you can use up to eight systems simultaneously.
The PRO 92cW is a headworn condenser microphone with a flexible boom and a shaped earpiece that fits over your left or right ear. It has a frequency response that is optimized to reproduce clear speech without coloring the sound. It features an omnidirectional polar pattern which is designed to provide a large acoustical pick up radius. This helps to ensure that your speech or performance is captured accurately, and it allows you to speak comfortably with the mic sitting near the corner of your mouth. The mic is fitted with a windscreen to filter out pops from breath and wind noise, and it has a 55" cable that terminates with a locking 4-pin connector which plugs into the ATW-T1001 UniPak pocket transmitter.
The ATW-1101/H92 wireless system is engineered to quickly find the best signal possible, utilizing an automatic frequency selection function that chooses open bands for you when you "pair" your transmitter with the receiver. Also designed to combat interference, the ATW-1101/H92 uses three different diversity techniques. Using frequency diversity, the system sends the wireless signal on two separate channels simultaneously and chooses the one with the clearest signal. It also transmits the signal across multiple intervals in time in order to fight multipath interference. This is known as time diversity. Furthermore, the system also makes use of space diversity, choosing between the receiver's dual antennas depending on which is picking up the best signal integrity.
