Product FAQ's

Ask a Question

  • Will the record out function on the STX-101 pass the audio signal to a computer via a RCA cable?

    The record out function of the OTS STX-101 is designed to send an audio signal to a recording device like a VCR or Tape Recorder. We haveve never connected one to a laptop or desktop computer before but if your device has an audio input and recording software that draws its data from the audio input then it should work. You would also need to make sure you have a cable that will mate with both devices.
