Introduction
The Phoenix Octopus Conferencing Mixer utilizes Beamforming microphone array technology, provides unlimited daisy chain
capability, and allows for multiple connectivity options all in a single, easy to install box. The Octopus gives the ability to mount
microphones and speakers anywhere in the room (ceilings, walls, and table tops). It comes standard with USB and RCA connectors
for VoIP and Video Codec connectivity, with the option of adding a PSTN (analog telephone) interface or a digital telephone
interface. The Phoenix Octopus can be ordered with an optional 40 watt, 4-output amplifier for powering speakers. Each Octopus unit
has four microphone inputs, each of which can be set for Mic (3V or 24V Phantom available). Each of the four inputs can be set to
participate in the Beamforming process, or designated as a unique Auxiliary or Sound Reinforcement channel.

The Octopus utilizes Phoenix Audio’s proprietary Beamforming algorithm. It performs echo cancellation, noise suppression, and de-
reverb filtering to rid the send signal of unwanted echo and reflected sounds.
