IQMUX34 3G/HD/SD 8 Channel Analog Audio Embedder

The IQMUX34 provides eight-channel analog audio embedding for 3 Gb/s SDI, HD-SDI 1.5 Gb/s or SD-SDI 270 Mb/s signals. Audio processing features include audio delay, gain, invert and channel-level routing, while video delay and a video proc amp are also included in the feature set. The IQMUX34 is ideal as a general analog audio ingest module for incorporating local audio feeds.

FEATURES

  • 8-channel 3G/HD/SD-SDI embedder for analog audio inputs
  • Standards supported:
    • 3G-SDI to SMPTE ST 424/425 level A & B compatible
