NSPE Show 2026, Hanoi, Vietnam

The first day of the NSPE Show 2026 saw a remarkable turnout at our booth. The team from Techsound Vietnam demonstrated exceptional dedication and enthusiasm, providing thorough answers to numerous questions regarding technology, applications and components. The Alligator Line Array demonstration in the Line Array Showcase Area was a particular highlight, impressing visitors with its advanced German DSP technology, precisely calculated FIR filters for coherent dispersion and the substantial headroom of our power amplifier modules. We would like to express our sincere gratitude to the Techsound team for their remarkable commitment.
