Directional Mix

Role
Prepares low and high pitches to be treated differently. Directionality can be applied to high pitches, while low pitches always remain in omni.

End user benefit
Rich sound quality and enhanced ability to understand speech while retaining awareness of surroundings.

The lower signals, whose frequencies are below the crossover frequency are amplified as omni. The crossover frequency depends on the space between the hearing instrument’s two microphones.
