IQSYN31

Dual 3G/HD/SD-SDI Frame Synchronizer with Embedded Audio Processing

The IQSYN31 provides frame synchronization for HD-SDI at 3 Gb/s or 1.5 Gb/s, or SD-SDI 270 Mb/s with 16-channel embedded audio processing. Enabling powerful processing features with a space-efficient two channels per card, the IQSYN31 is ideal for incoming line applications where space is at a premium. A video proc amp provides complete control over the video levels, and audio processing features include Dolby E auto-alignment, audio delay, gain, invert and channel level routing.

FEATURES

  • Dual-channel 3G/HD/SD-SDI synchronizer with up to 3 frames of video delay per channel
  • Processing for 16 channels of embedded audio present on each incoming SDI stream
