I want to send toslink to my current dac. does the optical setting bypass the built in dac? or does it do a digital to analog to digital conversion.

Hi, when optical and coaxial output, digital to digital directly (USB to optical or coaxial). When the headphones output, digital to analog directly. Thank you.

With usb digital input, will the digital output be available on both the digital optical and rca s/pdif outputs simultaneously?

Actually, when in digital mode (of the two modes) it outputs both on the coax and optical jack. I've tested it myself running an optical cable to my bluetooth transmitter and the coax running to my desktop headphone dac for my wired headphone amp stack. The toggle switch on the unit is to switch between those 2 jacks and the headphone out which is digital to analog.

Hi does the optical port support surround channels?

This supports dual channels, doesn't support surround channels. Thank you

Can you use a usb-a to usb-c cable for input? I don't have a usb-c out

Hi, this comes with a USB-A male to Type-C male Cable. Thank you.
