Audio Technica AT-One ATW-11 (Beltpack System Only)


The Audio Technica ATOne ATW11 Beltpack System is designed with simplicity and ease-of-use in mind. Equipped with a practical carrying case, rack-mount kit and detachable antennae, AT-One is the perfect balance of price and performance, ideal for those looking for accurate, reliable performance at an entry level price.

The AT-One’s frequency plan is divided into two groups with 4 available channels in each group split between the Europe wide license free frequency range and the LTE duplex gap. Users can choose up to 4 channels within one group. Available in three configurations, AT-One can be purchased with a beltpack or handheld transmitter.

The ATW-11 comes equipped with a sturdy, discreetly designed beltpack, providing 10mW RF output power, damping switch and a battery life of 10 hours. The ATW-13 handheld system features the ATW-T3 cardioid condenser handheld transmitter, again with 10mW RF output and 10 hour battery life. ATW-11/P comes equipped with the ATR35cW tie-clip microphone.

The ATW-13’s condenser handheld microphone prevents the possibility of feedback when used in venues with induction loops installed.
