FAQS

Q1: What is "bus-based AEC," and how does it improve audio quality in conference calls?

Bus-based AEC (Acoustic Echo Cancellation) eliminates echo in conference calls by processing audio on a shared bus, providing superior echo cancellation (512ms tail length, 60dB reduction) compared to basic AEC. This results in clearer, more natural-sounding conversations.

Q2: The processor has multiple mixing modes (AMC, Gate Mixer). What's the difference, and when would I use each?

AMC (Gain Sharing Automatic Mixing): Automatically adjusts the gain of multiple microphones, keeping the overall output level constant while prioritizing active speakers. Best for natural-sounding conversations with multiple participants. Gate Mixer: Automatically mutes microphones below a set threshold, reducing background noise. Ideal for situations with fewer active speakers at any given time.

Q3: This processor has central control features. Can it control other devices in my AV system?

Yes. The built-in central control can manage power, signal routing, environmental controls (like lighting or shades, if connected), and audio settings for the entire system, allowing for simplified, one-touch operation. This means you can program it to turn on/off devices, switch inputs/outputs, and adjust settings with a single command.
