The ZVOX AV157 Dialogue Clarifying Soundbar uses 12 levels of dialogue boost -- six stages of AccuVoice boost plus six stages of their latest SuperVoice technology. SuperVoice takes dialogue clarity to a new level by dramatically reducing non-vocal background sounds. This technology sets a new standard for the audio industry. The results are simply amazing. No other product offers so much flexibility and voice clarity enhancement.In most instances when you can't understand voices on TV, you turn it up. The problem is that when you do, you turn up background sounds, music and sound effects which and prevent you from understanding dialogue. The AV157 uses proprietary digital algorithms that separate the voices from the rest of the soundtrack and then manipulate them much like a hearing aid does. The result is uncanny. Voices simply "jump out" of the soundtrack so you can hear them clearly.Product Features:
