Setup and Connection

Follow these steps to properly set up your eSynic Digital to Analog Audio Converter:

1. Power Connection: Connect the provided USB power cable to the converter's 5.5mm power input. Plug the other end of the USB cable into a 5V 1A USB power source (e.g., a USB port on your TV, a USB wall adapter, or a computer USB port). Note: Ensure the power source is 5V 1A. Using other voltage/current sources may damage the device.
2. Digital Audio Input:
   • For Toslink (Optical) input: Connect one end of the Toslink cable to the optical output port of your digital audio source (e.g., TV, Blu-ray player, game console) and the other end to the "Optical-In" port on the converter.
   • For Coaxial input: Connect a coaxial cable (not included) from the coaxial output port of your digital audio source to the "Coaxial-In" port on the converter.

   Important: The SPDIF input must be set to stereo PCM. Please configure your source device's audio output settings to PCM or LPCM. This converter does not support Dolby 5.1 or other multi-channel formats.

3. Analog Audio Output:
   • For RCA Output: Connect RCA L/R audio cables (not included) from the "Output R" (red) and "Output L" (white) ports on the converter to the corresponding L/R analog audio input ports on your amplifier, stereo system, or active speakers.
   • For 3.5mm Jack Output: Connect a 3.5mm audio cable (not included) from the "3.5mm Headphone Audio" jack on the converter to your headphones or other 3.5mm input devices.

   Note: Both RCA and 3.5mm outputs can be used simultaneously.
