Basic features
Basic Features

  • Stereo Analog Input and Outputs (left and right channel) – RCA connectors

  • Analog Audio Compatible with 2Vrms Line level for CD, DVD and BD Players

  • Digital Audio Input and Outputs - SPDIF over coaxial - for RCA connector

  • Digital Audio (IEC60958) supporting standard CD, DVD and BD sample rates at 32kHz, 44.1kHz, 48 kHz and 96kHz

  • Supports 2-channel linear PCM digital audio and 5.1 Channel Dolby Digital and DTS encoded bitstreams.

  • Converts linear PCM digital input to analog output – and analog input sampled at 48kHz to digital output

  • User selectable digital delay functions for audio delay in millisecond, video frames and external delay set in feet or meter

  • Delay time selectable from 0 to 510 milliseconds in 1 msec increments– or 0 to 16 video frames (both 50Hz and 60Hz TV-systems)

  • Delay time for analog or digital at 48Hz sampling rate – up to 340 millisecond

  • External delay up to 510 feet or 155 meter
