Description

H-2A-ENC Professional 2-Channel Audio Encoder

The Thor Broadcast H-2A-ENC is a professional two-channel audio encoder designed for digital broadcasting, IPTV, cable television, satellite contribution, hospitality television, and professional A/V distribution systems.

The unit accepts both balanced analog audio and AES/EBU digital audio through professional XLR interfaces and encodes the incoming audio using MPEG-1 Layer II or AAC.

An integrated ASI input allows external transport streams to be multiplexed with the encoded audio. Two independent ASI outputs provide selectable MPTS, SPTS1, or SPTS2 transport streams, while the Gigabit Ethernet interface delivers encoded content over UDP/RTP unicast or multicast IP networks.

Front-panel LCD controls and browser-based Web GUI management make the H-2A-ENC easy to configure and integrate into professional broadcast headends.

Features

  • Two audio encoding channels
  • Balanced analog audio inputs
  • AES/EBU digital audio inputs
  • Professional XLR connectivity
  • MPEG-1 Layer II encoding
  • AAC encoding
  • 48 kHz audio sampling
  • 16-bit sample accuracy
  • Selectable bit rates from 64 to 384 kbps
  • Left, right and stereo encoding
  • AAC stereo encoding
  • Adjustable input audio gain from -12 dB to +12 dB
  • One ASI input for transport-stream multiplexing
  • Two independent ASI outputs
  • ASI output mirror selection for MPTS / SPTS1 / SPTS2
  • UDP/RTP IP output
  • Unicast and multicast operation
  • 100/1000M adaptive Ethernet
  • Maximum 64 PIDs for multiplexing
  • LCD and keypad local control
  • Web GUI remote management
  • Ethernet software upgrade
