  • Hybrid master control desk for analog and digital audio signals
    Patent number: 5014341
    Abstract: For a digital/analog master control desk for audio signals, it is proposed to sum the analog channel signals, possibly while simultaneously processing them. Forming the analog broadcast signal, this sum is added to a further channel signal A.sub.n which is formed of the analog-converted sum of the digital channel signals. A digital signal D.sub.n obtained from the digital-converted sum of the analog channel signals is added to the sum of the digital channel signals, resulting in a digital broadcast signal which has the same modulation content as the analog broadcast signal.
