Done.
Also when learning how to run audio for professional events, most people learn on and analog desk, because they are cheaper and they are extremely basic, then you get to learn digital which can be very confusing, because the controls of an analog console are essentially the same across all brands, however digital interfaces change drastically across all brands which makes it very difficult to figure out how to use consoles from all brands
While rack mount systems like these have their applications in professional audio, we tend to use desks just like the analog consoles, except they are almost completely digital, so we still have our faders, but everything else is all done with a large screen, and the most commonly used system on broadway for theaters is the digico SD-8 costing $250K US. For portable rigs Yamaha’s most popular digital systems are the QL and CL series, the QL costing about $16K, and the CL costing about $30K
Nice one Dave, Enjoyed that one.
On slot 1 and 2 u still have balanced input change only the connector from XLR to Stereo Jack, but if u look the corner bottom right u have the pinhead of each jack: hot cold and shield\ground of each one. identical is on XLR connectors only different shape to fit em in less space.
The output has that connector couse probably was paired to an analog recorder or with the same module with version analog input u can pair the unit to a more recent Yamaha mixer 🙂 ( and connecting 1 wire with 2 connectors compared to 16 wires 32 connectors save a lot of time :D)
love the back to the future reference!
More pro audio videos please.
"The Duck's Guts." I think I might love this guy.
This kind of mixer was my wet dream when I was doing the live A/V for my school.
Have you ever done a tear down in a sonar?
Coole timemachine on left side 😂😀
So, what'd you do with the add on cards?….
Big asses every where. Gota love it.
Now Teardown an Akai MPC ! 😉 Best is Renaissance 😀
Maybe it's something to do with the standard audio electronic best practice of SPG (Single Point Ground)… I think you should maybe get a audio electronic engineer on the next audio equip teardown.

OMG!!! Dave is using a non-manual screwdriver!!!!! A FIRST!
Emergency light in case you accidentally plug in your mixtape 😀 thumbs up
