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/H-T8 includes the UniPak® transmitter with variable trim adjustment, on/off/standby switch, and pro-grade 4-pin locking connector for the included PRO 8HEcW hypercardioid dynamic headset microphone, offering professional quality vocal reproduction in a hands-free form factor. The flexible boom can be configured to rest on the right or left side of the user's head, and offers nearly unlimited adjustability to accommodate virtually any speaker or vocalist's needs and comfort. All components fit conveniently in an included rugged case, ideal for storage and life on the road.
