Tesira SEC-4 Tesira 4 Channel Mic/Line Input Card

Tesira SEC-4 Acoustic Echo Cancellation Input Card
The Tesira SEC-4 is a high-performance modular input card designed for use with Tesira SERVER and SERVER-IO devices. This four-channel mic/line input card features Acoustic Echo Cancellation (AEC) on every input, ensuring crystal-clear audio in conferencing and telephony applications. With Biamp’s SpeechSense technology, the SEC-4 intelligently enhances speech clarity by accurately distinguishing human voices from background noise.

Advanced Acoustic Echo Cancellation for Uncompromised Clarity
With built-in AEC on all four inputs, the Tesira SEC-4 eliminates unwanted echo and ensures clean, intelligible audio for remote participants. Whether used in conference rooms, boardrooms, or lecture halls, this card enhances communication by preventing disruptive echoes that can arise from open microphones and speaker systems.

SpeechSense Technology for Superior Speech Processing
Biamp’s SpeechSense technology further refines audio performance by detecting and prioritizing human speech over other environmental sounds. This makes the SEC-4 an ideal choice for speech-heavy applications, such as teleconferencing and public address systems, where vocal intelligibility is critical.

Optimized Noise Reduction and Signal Processing
The SEC-4 goes beyond standard AEC with additional noise reduction on its output signals, ensuring that transmitted audio remains clean and free from background distractions. Integrated high-pass filtering further refines the signal, reducing low-frequency noise that can compromise speech clarity.

Seamless Integration with Tesira Systems
Unlike standalone DSP units that require significant processing power for AEC, the Tesira SEC-4 operates independently without consuming additional resources from the Tesira SERVER or SERVER-IO DSP. This makes it a scalable solution for expanding input capabilities in larger systems while maintaining optimal performance.

Durability and Compliance for Professional Installations
Built to meet Biamp’s rigorous standards, the Tesira SEC-4 is RoHS compliant and AES grounded, ensuring long-term reliability in professional AV installations. Additionally, it meets the requirements of the United States Trade Agreement Act (TAA), making it eligible for GSA Schedule contracts.
