VHF Wireless Unipak System

The Audio-Technica ATW-901A/G System 9 is a VHF wireless microphone system built for live sound reinforcement. It comprises a receiver, a bodypack transmitter and an AT-GcW guitar/instrument input cable. The receiver offers four selectable VHF frequencies at 169.505, 170.245, 171.045 and 171.905 MHz. Dual dipole antennas extend the operating range for stage use.

AT-GcW Guitar/Instrument Input Cable

The included AT-GcW cable connects a guitar or line-level instrument directly to the bodypack transmitter, eliminating the need for a separate microphone. This lets instrumentalists move freely on stage while retaining a direct signal path. The receiver provides both a balanced XLR output and an unbalanced 1/4" output for flexible mixing desk connections.

Check VHF Frequency Availability

Verify that the four available VHF frequencies are permitted and free from interference at your venue or region before purchase. The system does not offer frequency-agile scanning or UHF band options. Ensure your mixer or PA has a compatible XLR or 1/4" input and that a suitable DC power supply is available for the receiver.

Questions about this item

How often will the bodypack transmitter need fresh batteries?

The transmitter runs on standard batteries; replace them when the RF or AF LED indicators show low signal or distortion during use.

Which frequency among 169.505, 170.245, 171.045, or 171.905 MHz gives the most reliable link on stage?

Choose the channel with the least local interference; each of the four VHF frequencies performs similarly until another device occupies the same band.

Does the receiver run hot or draw extra power when left on all day?

The DC-powered receiver stays cool and draws minimal current; the power-cord hook prevents accidental unplugging during long sessions.
