1T-AP-216 Audio Converter changes Analog Stereo Audio (R&L) to simultaneously available SPDIF Optical and Coaxial Digital audio. Sampling is at 48Khz and transmission distances of over 5m (16 ft) are possible using the Optical Output. The Coaxial Digital Output transmission distance is limited by the quality of the cables and sensitivity of the receiving circuitry. A special feature of the 1T-AP-216 allows the introduction of a 150ms delay into the Digital Data Stream intended to correct lip sync problems frequently present on HDTV broadcast programming. The unit is immune from electromagnetic noise and is easy to install and operate. The unit requires external 5VDC and an AC Adapter is provided. It has a locking DC connector for added security.
