|   Audio-technica AT-MX341A SmartMixer® Four-channel Automatic Mixer The AT-MX341a automatic mixer is ideal for meetings, seminars, teleconferencing, worship services, radio and TV broadcasting and A/V applications. All switching is under microprocessor control with proprietary algorithms for instant, seamless operation. An individual priority pre-select switch for each mic/line channel allows choice of one-channel-at-a-time operation, all channels active, or any mix of moderator override. The last microphone on stays on so that ambient sound is never muted. Plus, any number of SmartMixers can be linked to create a system for large multi-mic installations. The priority control system extends throughout the entire chain.
