A cutting-edge solution for audio conferencing, the MT454-DTI Octopus USB Base Unit with Digital Telephone Interface is a versatile and robust mixer that leverages advanced DSP and unique technology to deliver crystal-clear audio. This unit is designed to automatically monitor and mix audio, simplifying setup and usage.
Equipped with four microphone inputs, each of which can be designated as a unique auxiliary or sound reinforcement channel, the Octopus offers unparalleled flexibility. It allows for strategic placement of speakers and microphones anywhere in the room, including the ceiling, walls, and tabletops, to ensure optimal audio capture and delivery.
One of the standout features of the Octopus is its unlimited daisy chain capability, which facilitates multiple connectivity options. This feature, coupled with its echo cancellation, noise suppression, full duplex communication, de-reverb filtering, and automatic gain control, ensures superior audio quality.
The Octopus also boasts a phantom power supply (3V & 24V) and utilizes beamforming microphone array technology. This technology enables the Octopus to instantaneously assess the signals picked up by all the microphones and decide which ones will participate in the mixing and at what level of emphasis.
The bridging feature of the Octopus allows for 3-way communication between multiple connection sources, such as telephone, VoIP, and video codec. The MT454-DTI model comes standard with USB and RCA connectors for VoIP and video codec connectivity and can connect to any digital phone via the phone's headset.
Additional options for the Octopus include an analog (PSTN) telephone interface and/or a 40-watt, 4-output amplifier for powering speakers. This makes the Octopus MT454-DTI an ideal solution for various settings, including small to very large conference rooms, classrooms, training rooms, courtrooms, webinars, web conferences, and auditoriums.
The Octopus USB Base Unit with Power Amplifier (MT454-PA) connects via digital output (USB to your computer for any session using your computer, such as Voice Over IP applications like Skype, Vidyo, etc.), analog output (RCA, XLR, Phoenix speaker output connectors), and speakers (spring-clip connectors).
The Octopus is not just about performance; it's also about simplicity and flexibility. Its powerful DSP delivers high-definition audio, while its design allows for easy installation and setup. The unit automatically controls the mixing parameters, making it a set-it-and-forget-it solution. With unlimited daisy chain capability, it can accommodate any room size. Furthermore, its flexible connectivity options and the ability to mount speakers and microphones in various locations make it a versatile choice for any audio conferencing needs.
