Product Detail
The Audio-Technica ATW-901A/L System 9 VHF Wireless Unipak System is a great choice for live sound reinforcement. It includes a wireless VHF receiver, a bodypack transmitter, and an omnidirectional lavalier microphone. The receiver uses two dipole antennas to extend the range and lets you pick from four VHF transmission frequencies: 169.505, 170.245, 171.045, or 171.905 MHz. It has LED indicator lights for channel, RF, and AF peak. At the back, there's a volume control knob, a squelch control knob, a balanced XLR audio output, and an unbalanced 1/4' audio output. There's also a power cord hook to stop accidental DC power supply pull - outs. The bodypack transmitter runs on two AA batteries. It has variable microphone and instrument trim, channel selection DIP switches, a Power/Mute button, and a Unipak input connector. This system offers a 90 dB dynamic range, a 200' operating range in an open environment, and a frequency response from 80 to 13,000 Hz. The receiver has a non - diversity, single - channel, dual - antenna system with at least 50 dB image rejection. The bodypack transmitter has a high RF power output of 10 mW and meets federal and national spurious emission regulations.
Using this Audio - Technica wireless lavalier microphone system is easy. First, set up the receiver. Plug it into a 100 - 240 VAC power source using the provided external power supply. Then, choose your preferred VHF transmission frequency from the four available options. Adjust the volume and squelch settings according to your needs. For the bodypack transmitter, insert two AA batteries (not included). Connect your microphone or instrument to the four - pin locking connector. You can use the variable trim to adjust the input level and select the channel using the DIP switches. Press the Power/Mute button to turn it on or off. When using the system, keep it in an open area to get the best operating range of 200 feet. Avoid very low temperatures as battery performance may be reduced. For maintenance, clean the microphone and connectors regularly with a soft, dry cloth. Store the system in a cool, dry place when not in use. Make sure to follow all federal and national regulations regarding spurious emissions.
