CONSOLIDATGA3227: Pre-configured DSP System for Hearing Aids, with up to 2 WDRC channels
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.
