The HT-45 analog high-performance wireless handheld transmitter features a dynamic microphone capsule for demanding vocal performances. The cardioid polar pattern ensures maximum gain before feedback and lets your voice cut through any mix. Its spring-steel wire-mesh front grille protects the transducer from the hardships of on-stage use. The HT45 provides a gain control for perfect adjustment of the input volume and a noiseless on/off/mute switch. A battery status indicator shows red before the battery goes dead, allowing the user to fully control his performance time.
