DESCRIPTION
The CONSOLIDATOR GA3227 hybrid is a DSP system based on a two−channel compression circuit. It can be configured as a single channel linear device or a single, or dual, channel WDRC device. It can efficiently replace traditional analog hearing aid compression circuits without compromising fundamental performance requirements. The Consolidator GA3227 hybrid can be configured as an extended programmable circuit or a trimmer circuit supporting manual configuration. As a trimmer circuit, it continuously monitors trimmer positions and translates them into the hearing aid parameters of choice. Also included in the ConsolidatorFEATURES
