Product Details

The Automix Matrix 780 provides tools for consistently clear audio in courtrooms, government chambers, corporate boardrooms and houses of worship.

Setup is easy and efficient with a straightforward Windows® interface connected over Ethernet. Compatible with Symetrix RS-485-based Adaptive Remote Control (ARC) Wall Panels for user control.

An interactive front panel provides convenient access to vital system parameters or may be programmed for user and technician control.

Open Collector outputs drive LEDs directly for status updates or integrate with external logic and automation systems.

Featuring:

• Twelve inputs (eight microphone, four line level)
• Eight outputs
• Automixing (Gating and Gain-sharing) and Submixing
• Routing and Processing
• Matrix mixing
• Microphone pre-amplification
• Feedback elimination
• Compression  and Equalization
• Limiting and Delay
• Filters and AGC
