The ANC-1 allows the Vocia® system to adjust output levels automatically in response to changes in ambient noise levels. The ANC-1 is a networked device for use with Biamp's Vocia Amplifier (VA-8600). It accepts two ambient noise inputs at microphone or line level. Most high-quality dynamic and condenser microphones can be used in conjunction with the ANC-1. Input gain for each of the two inputs is user configurable via the Vocia software interface. The ANC-1 processes the ambient noise information using Biamp's adaptive ambient noise compensation algorithm and sends data to the VA-8600 to change the output level accordingly. The Vocia software interface permits comprehensive adjustment of ANC parameters. The ANC-1 utilizes IEEE compliant Power over Ethernet (PoE) technology.
