Product Description

Phoenix Audio Octopus Base unit with 4 Raven Microphones

Octopus MT454

The Octopus is an Audio Conferencing Mixer that gives you crystal clear audio. Using the Octopus allows you the freedom to mount microphones and speakers anywhere in the room (ceiling, walls, and table tops) for professional sound and a sleek look. The Octopus has a high powered DSP and technology that automatically monitors and mixes the audio. Although this may sound complicated we designed it for simple set-up & use, giving you a “set it and forget it” solution.

Each Octopus has four microphone inputs (each input can also be designated as a unique auxiliary or sound reinforcement channel), however, the Octopus provides unlimited daisy chain capability, and allows for multiple connectivity options. 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.
