The Uno offers the benefits of high fidelity sound, wide bandwidth of 12 kHz and 95 dB of input dynamic range. Uno I is a fully programmable digital hearing aid. Four independent controls provide flexible support for fine-tuning Uno I to match the user's distinctive hearing correction needs. High Power output drive capability of 138 dB SPL and support for up to 83 dB of electrical gain enables the Uno to serve as a high-power hearing aid for those who have severe hearing loss as well as mild to moderate hearing loss profiles. In addition to the above features, the Uno I offers programmable WDRC signal processing, wideband level detection, AGC-I parametric adjustment strategies, optional peak clipping, and low battery indicators. Wide Dynamic Range Compression (WDRC) offers numerous benefits over linear hearing instruments. WDRC mapping strategy allows perceived loudness for Uno users to be matched to that of a person with normal hearing. The amplified sound is clearly audible and comfortable to the user. WDRC also amplifies soft sound. Understanding quiet speech is achieved with Uno I hearing aids. Uno's WDRC processing provides consistently high speech understanding in all environments. - Fitted with a choice of prescriptions - Fully configurable channel structure and compression parameters - Suitable for all hearing losses - Enables individual programs to be configured differently
