ClassIn DT1 All-in-One Beamforming Microphone

ClassIn beamforming microphone designed to enhance audio capture in various settings, including classrooms and conference rooms.

Model: DT1

The ClassIn DT1 Beamforming Ceiling Microphone revolutionizes audio capture with its sophisticated microphone array technology. Designed to automatically track human voices based on vocal characteristics, it ensures optimal speech clarity in any environment. Its configurable pickup area can be adjusted to include up to eight exclusion zones and five priority areas, providing unparalleled flexibility.


The precise beam positioning offers real-time output with 1° accuracy, making it ideal for dynamic audio environments. The open API protocol allows seamless integration and control via third-party devices, while multiple installation options, including hanging kits and embedded setups, ensure versatility. Additionally, the system supports multi-level microphone array cascading, enhancing its adaptability for larger spaces.



The AI Voice Processor within the ClassIn DT1 offers advanced audio processing capabilities. It features a proprietary protocol for configuring digital audio matrices from input to output paths, four channels with Acoustic Echo Cancellation (AEC) functionality for microphone/line inputs, and two microphone/line outputs.


The USB audio path configuration and expandable I/O via A2B allow for cascading expansion through an RJ-45 connector. Users can effortlessly manage signal routing, mixing, echo cancellation, feedback suppression, automatic gain control, noise reduction, dynamic range control, and equalization through intuitive software.


The in-built speaker amplifier supports external passive speakers, and the system’s ability to daisy chain from master to slave microphones makes it a robust choice for comprehensive audio solutions.
