Delhi High Court: A New Standard in Audio Clarity

The Delhi High Court, one of India’s most prestigious judicial institutions, underwent a multi-million dollar expansion in 2020, adding 18 new courtrooms to accommodate its increasing case-load. As part of this expansion, the Ministry of Law and Justice overhauled the courtroom audio-visual systems to ensure clear communication and seamless AV integration with modern technology.
