AKG HT45 Handheld Wireless Transmitter
The HT45 is the handheld transmitter for AKG's Perception Wireless 45 system, built around a cardioid dynamic capsule that gives useful gain before feedback on a small stage. The spring-steel wire-mesh grille is there because handhelds get dropped, and the P5 head under it is the same voicing AKG uses on its wired stage dynamics.
A gain control on the body sets input level to the singer instead of leaving it to the receiver, and the on/off/mute switch is noiseless so nothing thumps the PA between songs. The battery indicator turns red before the cell goes flat, and a single AA gives up to 10 hours. Add one to an existing Perception Wireless 45 rig when a second vocalist joins.
