Audio Technica's Pro Series 3 systems provide reliable rock-solid performance, simple operation, and exceptional sound quality. Available in handheld, headworn, guitar/instrument, lavalier and bodypack-only configurations, the Pro Series 3 Wireless Systems are single-channel, fixed-frequency systems available in three VHF travelling frequencies (169.505, 170.245, and 171.905 MHz; designated T2, T3, and T8, respectively) that operate outside the range of US broadcast television. All three fixed-frequency systems work together with no interference from TV channels, and no frequency coordination is required.
Each Pro Series 3 Wireless System includes a PRO-R300 receiver. The PRO-R300 is a non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, which improves operation by providing a ground element in addition to the usual signal element. The PRO-R300 also offers volume control along with AF Peak, RF and Power indicator lights. The PRO-301/L-T2 includes the UniPak® transmitter with variable trim adjustment, on/off/standby switch, and pro-grade 4-pin locking connector. Rounding out the package is the Audio-Technica omnidirectional lavalier microphone, offering professional quality vocal reproduction in a discrete hands-free form factor. All components fit conveniently in an included rugged case, ideal for storage and life on the road.
