The Phoenix MT-400 Conferencing Mixer utilizes a beamforming microphone array technology, provides unlimited daisy chain capability, and allows for multiple connectivity options all in a single easy to install box. The MT-400 series gives you the ability to mount your microphones and speakers anywhere in the room (ceilings, walls, and tabletops). It comes standard with USB and Terminal Block connectors with the option of adding a PSTN (analog) interface or a Digital Telephone Interface. The Phoenix MT-400 can be ordered with either four or eight phantom powered microphone inputs mixing into one line level output.

Another member of the Phoenix MT-400 family is a four-channel Line Input module. Each of the four inputs of the Line Level Module can be configured as a standard Line Level Microphone such that will participate in the beamforming process, or as a unique Auxiliary or Sound Reinforcement channel. This unit is particularly well suited for wireless mics. In addition to the beamforming Mixing Technology the Phoenix 400 uses Phoenix Audio proprietary cancellation, noise suppression, and de-reverb filtering to rid the send signal of unwanted echo and reflected sounds.

All MT-400 units can be daisy chained and mounted together in order to facilitate rooms with any amount of installed microphones.
