Audio Technica ATW-T310b UniPak® transmitter

The ATW-T310b wireless UniPak® body-pack transmitter has both low and high impedance inputs plus a 5V DC bian connection allowing it to be used with condenser and dynamic microphones, as well as Hi-Z instrument pickups. The locking 4-pin HRS-type audio input connector is recessed to protect the connection from damage. Operating on two standard AA batteries, the transmitter features high and low-level RF output settings. The low-level setting allows two additional hours of bttery life while retaining a strong RF signal link. Soft-touch controls provide convenient access to a variety of functions including: RF power, audio input level, power/mute locks and frequency selection. Each transmitterʼs backlit LCD display presents a great deal of setup and operating information clearly and conveniently including battery fuel remaining, mute, and operating frequency. A flashing "Lo-Batt” alert visually signals the battery life is almost depleted. A dual-colour status LED illuminates green when power is on, and red when the transmitter is muted. Programmable power/mute locks limit the functioning of the transmitterʼs power/mute button as desired for particular users and applications. To match the audio input level to the transmitter, a four-position audio input gain setting selected through the function menu is provided.

The body-pack transmitter features a safety cover to protect the soft-touch controls from being accidentally activated and a recessed input connector to increase the life of the microphone cable. Constructed of high impact materials, the body-pack transmitter features a field replaceable whip antenna and captive locking battery cover door.
