Miranda HCO-3901-OPT-ALC-2 2-channel on-board ALC option - HCO-3901-OPT-ALC-2



The HCO-3901 is a 3x1 3G*/HD/SD/ASI change-over which support 16 channels of embedded audio and metadata. The module can perform a video and audio "Clean and Silent Switch" between sources using the CS option. In the event of a power failure, the PGM signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output. Relays are fully controllable via GPI. Input selection can be performed automatically or manually.

Key Features


  • Two primary inputs: IN 1 and IN 2 plus one secondary: IN 3

  • Four outputs: main program and three previews

  • Supports 3G, HD (1080i50/59.94, 720p50/59.94) and SD (525, 625) or ASI input

  • Electronic switching with relay backup (on rear module) maintains selected input with power loss for Primary inputs IN 1 and IN 2

  • Automatic mode using internal signal analysis with alarm parameters for IN 1 and IN 2

  • Manual change-over by local frame controller, iControl, iControl Solo, RCP-200 or GPI (3DRP rear) for 3 inputs

  • Alarm reporting to iControl facility monitoring and control system

  • Compatible with iControl end-to-end A/V fingerprint analyzer for lip sync error detection and measurement

  • GPI in and out (IN 1, IN 2, IN 3, auto, bypass)

  • Optional clean switch function (video and 16 channels of audio) for IN 1 and IN 2

  • Optional on-board automatic loudness control by Grass Valley

  • Reference input with passive loop through (3DRP rear only)
