3G/HD/SD-SDI Intelligent 1x8 Distribution Amplifier

Interact with this product in a Layout Tool:

The 7800IDA8-3G reclocking distribution amplifier provides high quality distribution of facility 3G/HD/SD-SDI signals. This module features an auto-sensing equalized input which generates eight reclocked outputs and is especially useful for projects where long cables runs are encountered.

Unlike other traditional DA's on the market, this module has been designed to support additional broadcast functionality such as loudness control, lipsync control, audio up and down mixing. These features can be optionally ordered providing more value to an already high performance distribution amplifier.

The 7800IDA8-3G is VistaLINK® capable, offering remote monitoring, control and configuration capabilities via Simple Network Management Protocol (SNMP) giving the flexibility to manage operations, including signal monitoring and module configuration from SNMP capable control systems (Manager or NMS)

This device:

  • Provides eight reclocked outputs from the 3G/HD/SD-SDI input
  • Provides enhanced signal reclocking and conditioning
  • Provides monitoring and fault detection for video loss, black and freeze
  • Provides monitoring and fault detection for audio loss, over and under
  • Offers embedded mono audio channel shuffling (with any of the +UMX, +DMX, +IG options)
  • Offers 2-channel stereo to 5.1surround sound upmixing (with the +UMX option)
  • Offers 5.1 2-channel stereo downmix (with the +DMX option)
  • Offers award winning IntelliGain™ loudness control (with the +IG option)
  • Offers award winning IntelliTrak™ Lipsync control (with the +IT option)
  • SNMP configuration via 7800FC Evertz frame controller

The 7800IDA8-3G occupies 1 card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, or the portable 3RU 350FR frame which has a 7 slot capacity. The 7800FC frame controller is required for configuration.
