Telefunken CN-750 HighCOM noise reduction unit (1981) - Demonstration

This is a 1981 Telefunken CN-750 HighCOM noise reduction unit. It features the first generation of the Telefunken Highcom NR system, which was a more budget-friendly development for consumer application from the Telcom C4 noise reduction system. HighCOM is a single-band 2:1:2 compander. Later versions were the 2-band HighCOM II system that Nakamichi & Telefunken developed together, and the almost non-existent HighCom III system. Enjoy!
