Cyrus Dad3 digital line out


2010-07-13 1:38 pm
The cyrus dad3 player only had optical digital output.
I have modified my player to have digital line out. Why you ask.

Because I have a cyrus dacmaster that when turned on, defaults to pro input, which is digital input via xlr socket, so it saves me having press the optical input selector button.

Will post details and some photos over the weekend but basically it is a circuit based on 7404 hex inverters converting ttl input to the toslink driver to spdif level.

There are a few gotchas when fitting the circuit that I aim to cover.
