DESCRIPTION
A trimmer interface supports manual circuit configuration. It continuously monitors trimmer positions and translates them into the hearing−aid parameters of choice. A serial data interface provides full programmability at the factory and in the field. The Foundation GA3216 includes in−channel squelch to attenuate microphone and circuit noise in quiet environments. It also includes low−distortion compression limiting and programmable high and low cut filters, as well as five configurable equalization filters. Unused blocks can be powered down to save battery current, for example, when using the device in single−channel mode. The Foundation GA3216 Hybrid code programmed into the GC5020 controller chip is ‘1’.FEATURES
