Inputs and Outputs
The Essence One features digital S/Pdif input through coaxial and optical Toslink. This unit also features asynchronous mode USB.
Notes on USB input: The USB receiver in the E1 unit operates in Asynchronous Mode and as far as USB based audio is concerned this is the preferred method of USB communication. In this method, the DAC unit is controlling the flow of data which syncï¿½s the stream to the unitï¿½s internal clock. This method is preferred because the design is basically immune to jitter or any other type of clock anomalies.
The main volume control adjusts volume for the unbalanced (RCA) and balanced (XLR) outputs. To the right of that we can see the LED indicators that will show the end user what frequency is being sent to the device. We have from top to bottom:
