Audio-Technica ATW-901A/H System 9 VHF Wireless Unipak System with a PRO 8HEcW Headworn Microphone

Key Features 169.505 to 171.905 MHz Dipole Antenna for Extended Range Channel, RF, and AF Peak Indicator LEDs Balanced XLR & Unbalanced 1/4" Outputs Squelch Control Volume Control Cord Hook to Prevent Accidental Pull-Out Channel Selector Switches Instrument and Microphone Trim Control Professional Locking Bodypack Connector The Audio-Technica ATW-901A/H System 9 VHF Wireless Unipak System is designed for live sound reinforcement applications. The system consists of a wireless VHF receiver, a bodypack transmitter, and a PRO 8HEcW headworn microphone. The receiver utilizes two dipole antennas for extended range, and allows you to select your VHF transmission frequency from 169.505, 170.245, 171.045, or 171.905 MHz. The receiver includes LED indicator lights for channel, RF, and AF peak. The back of the receiver features a volume control knob, a squelch control knob, a balanced XLR audio output, and an unbalanced 1/4" audio output. The receiver also includes a power cord hook to prevent accidental pull-out of the DC power supply. The bodypack transmitter is powered by two AA batteries and includes variable microphone and instrument trim, channel selection DIP switches, a Power/Mute button, and a Unipak input connector. Four Selectable VHF Transmission Frequencies Select from 169.505, 170.245, 171.045, and 171.905 MHz Dipole Antenna for Extended Range The receiver utilizes two antennas to improve the range of the system Squelch Control The receiver features a squelch adjustment knob that controls the threshold for the radio signal that regulates audio output. If the radio signal from the microphone drops below the threshold, the squelch control mutes the audio output to prevent the transmission of radio interference and white noise from entering the speakers System Wireless Technology Analog VHF Number of RF Channel Frequencies 4 Included Transmitters 1 x Bodypack with Microphone Diversity Non-Diversity RF Frequency Band 169 to 172 MHz Max Operating Range 200' / 61 m Built-In Recorder No Control App Support No Encryption None Deviation ±10 kHz Modulation FM Receiver Receiver Type Tabletop Antenna 2 x Sleeve Dipole (Front-Mount) Number of Audio Channels 1 Audio I/O 1 x XLR 3-Pin Female Balanced Line Output1 x 1/4" TS Unbalanced Line Output Phantom Power Protection None Frequency Response 80 Hz to 13 kHz Network I/O None Word Clock I/O None USB/Lightning Connectivity None RF Output Power 10 mW Squelch Adjustable Spurious Rejection: >50 dB Power Requirements AC/DC Power Adapter AC/DC Power Adapter 12 VDC at 0.5 A, Center-Positive (Included) AC Input Power 100 to 240 VAC, 50 / 60 Hz Display & Indicators 3 x LED (AF Level, Channel) Operating Temperature 40 to 110°F / 4 to 43°C Dimensions 7.5 x 1.8 x 5.1" / 190 x 46.2 x 128.5 mm Weight 12 oz / 340 g Transmitter Transmitter Type Bodypack with Microphone RF Output Power 10 mW Audio I/O 1 x TA4/Mini XLR 4-Pin Male Balanced Input (Lockable) Pad None Muting Mute Switch Auto-Level Control No Signal Processing None Frequency Response 80 Hz to 13 kHz (Line) Antenna 1 x External Power Requirements Battery Battery Type 2 x AA (Not Included, Replaceable) Approx.
