DR680 digital input and channel assignment questions
« on: June 21, 2022, 04:06:03 PM »

I have a Tascam DR680 that I've been using mostly for it's digital input to transfer DATs from my Fostex D5. Works great.

I picked up a Warm Mod UA5 for really cheap with an eye towards using the SPDIF output to feed the MIX channel for a pair of mics and use the 1-6 inputs for direct outs from the SBD getting me a total of 8 channels on the same clock.

I'm kinda stuck about which menu settings can get me where I want to be - how do I set the SPDIF input to the mix channels so I can free up the other 6 inputs for analog in?

Make sure all the I/O for channels 1-6 are set to analog. Go into Menu then REC -> ST REC. Select DIN. Go into Function and select DIN MON. You have to do the DIN MON every time to get the DIN Lock message. Also, make sure the UA-5 is set to COAX in the back little switch. Won't work if it is set to optical. Also make sure the Stereo (Mix) channels are set to record.

Thanks this is what I was missing. Some of the control functions aren't named in such a way to make them easy to sort out.

Just saw this thread.  Good to hear fireon's advice got it working for you.

You probably realize this, but I'd like to clarify for others that you can slave the DR680's clock to the clock of another coax digital-out device, and subsequently choose to record that input to the "extra" stereo channel or not.  In this case, as will typically be the case for most tapers running an external preamp featuring a digital output, the intent is to record that digital input.  But in other scenarios you can still slave to the external clock [DIN LOCK], and either record no stereo channel at all, or record a mix of the other input channels of the 680, without recording the external digital source on the 680.  That can be useful when syncing clock with another digital-out recorder as a way of increasing channel count. 

I've recorded 10 channels that way with the DR680 in combination with an R44.  Most of the time in that scenario I have recorded two of the four additional R44 channels to the stereo channel on the 680 simply to make file alignment easier.  Those channels are then duplicated between both recorders making it easier to align the files from both machines.  And once initially aligned they remain aligned even over the course of a long recordings since they shared the same recordiong clock.

You have to do the DIN MON every time to get the DIN Lock message. Also, make sure the UA-5 is set to COAX in the back little switch. Won't work if it is set to optical. Also make sure the Stereo (Mix) channels are set to record.

To be clear, selecting DIN MON (or not) has no bearing on what gets recorded or whether you get DIN LOCK or not. It's purely for monitoring purposes while recording. The ST REC setting is the key one.
