On page 15 of Leon's very helpful(Thanks, Leon!)"Buffalo III DAC Integration Guide" it states that the correct reistors for AES/EBU (<7V) input are R<z> = 56R and RS<z> = 47R. I didn't receive reisistors of these values in the kit. Instead, I received resistor values of 68R and 43R. Out of an abundance of caution, before I solder the resistors I received into the circuit board, is it correct to substitute a 68R resistor for a 56R resistor, and a 43R resistor for a 47R resistor?

Thanks!:d/

I changed the values in the kits to be closer to the desired 110R termination impedance. Both values will work fine, however.

Brian, thanks for your prompt reply, and confirmation that the R values are correct.

Does this change also apply to the single S/PDIF level converter?
