• Two (2) Mic/Line inputs, two (2) Mic/Line outputs, two (2) AES3 outputs, Word Clock input
• Processing modules: Compression, Equalization, De-Essing, Downward Expansion, Highpass and Lowpass filters, Voice Symmetry
• Configurable named presets for each on-air personality – up to 50, including factory presets – using the included Windows® software over Ethernet
• Recall presets with convenient front panel controls, optional hardware remote(s), or third-party control protocol

Product Details

Flexible, powerful and easy to use, the Voice Processor 2x is a programmable microphone processor that is the first choice of Chief Engineers to make the most of that crucial link between the microphone and the audience.

Independent processing of two microphone channels, a rich DSP feature-set, and simplicity of operation for on-air talent combine to provide a powerful solution, all in one rack space.

The 2x offers a comprehensive set of voice enhancement tools employing Windows® software applications for total control of all essential parameters. Dial in that perfect sound and the settings are saved as named presets for later recall from the front panel or remotely. Any mic can be optimized for either male or female voices.

Sounding great is the bottom line and the Voice Processor 2x delivers the quality and control to get it exactly right, every time.
