Yamaha 02R digital mixing console.

They're in the rear panel. No need to take the lid off, just remove the panel and they're on the right hand side..

Excellent! That saved me a load of bother Thank you!

2.16TC chips fitted and everything seems to be fully operational.

However, I wanted to run the diagnostics but I can't seem to invoke the test system as outlined in the service manual. It tells me to hold down the STEREO SEL button and CURSOR > button together and power the device on. I get the pop up that says "DIAGNOSTICS? CANCEL EXECUTE" but when I select EXECUTE and hit enter, the system just seems to ignore it. Any suggestions? Did they change something in the 2.16 OS?

I've tried a system init. and that hasn't helped.

I can confirm that when you have SW 2.16 the diagnosis page is not avaliable anymore. The memory space is needed for the TC unity functionality.
I was thinking of making a piggy back : two times two IC's above and switch them with a switch.

Hello all,
New member here, I joined the forum today because I have found myself the owner of a Yamaha 02R, and was looking for some help sorting out a couple issues with it, forgive me if this isn't the right place to ask.

I scooped up the console from Facebook Marketplace from an older gentleman who bought it from a local music shop, but judging by the info written on the cover of the manual, I believe the original owners were a local college nearby. The console is a Version 2, and came with the meter bridge as well as two CD8-AD slot cards installed, with a few physical condition issues: the meter bridge connector on the bridge side was physically broken, but easily repaired, and one of the CD8-AD slot cards has some damage on it. I suspect the console took a hit at some point. The enter button was also broken, but I was able to find a new key cap online and replaced it last night.

As for the good: she boots up and seems to run fine, the battery is good according to the utility check, and all the faders seem to move alright, albeit a couple are a little sticky, I think some Deoxit might do them some good. I have the console tied to two M-Audio BX5 monitors on my desk curre tly via XLR through the main outputs, and the audio sounds really good, like better than the Presonus Studiolive 24.4.2 I also have. I feel right at home on this console, she's very close functionally the the LS9s and M7CLs I used to run when I was doing audio full-time.

Now for the bad: the Aux Sends seem to not be functional, nor the control room and monitor outs. There's audio on the lines but buried beneath a whole lot of hum and noise. I can reroute the Aux Sends to the CD8-AD cards and from there I get a better output, still with a bit of noise, but far less than out of the console directly. I'm wondering if any of you have had similar issues, and if there's something I should be looking at directly as a potential culprit.

I didn't spend much on this console, it was more of an impulse buy than anything at $100 US, but I'd like to tinker with it and see if I can get it working a little better. If anything, she's a neat conversation piece in my office. Thanks for any advice you all can give.

This thread seems to have become the go-to life line for these old things.

Sounds like you might have some electronic issues as the rear panel mounted outputs are quite hot on my examples. -18dBFS on the meter drives everything to just over reference assuming unity gain on my connected devices - I'm reasonably sure the manual quotes +4dBU. The noise floor isn't exceptionaly low on those outs but, at the same time is more than serviceable. Being honest, I've never really compared them via the digital version on the option cards but can't imagine it's a night and day difference.

As you've used LS9 and M7 before (I still love these two consoles, too), the DNA is definitely very similar indeed. Also, much like both of those, a little bit of a template / start scene setup on the 02R can save a good chunk of time.

What the 02R doesn't share with it's newer siblings is the omni outs - aux outs are that by default although they are switchable to the bus outs also but I would think you've already checked that.

The masters for the auxes are buried in the 'meter' page however, from memory, you can control them (on faders rather than the jog wheel) via the 'remote' page. To do this, hold the 'flip' button, select a remote channel (there's 4 available in the top left corner) and scroll through the control templates until you see 'bus / aux masters'. The faders will fly into position and become the controllers for your bus and aux masters. If it has a TC Electronic card, you'll control that from this page too.

Not meaning to insult or assume but lastly, check your pre / post settings as they are switchable per channel plus they're all switchable on / off too - something that seems reasonably unique to the 02R.

As for the CR / Studio outputs, the only things I can think is to check their routing options on the dual row of buttons that run down the right hand side of the console.

Good luck!

IC YSF210 - 4 Nos
Thank you.

Try eBay.
But I think it is too expensive to replace all the A-D and D-A convertors.
Maybe aliExpress is cheaper.

A bit of a minor hiccup this week with a rogue 'dimmer' button - frustratingly mid live album mix. Oddly, it'd been previously modded so the actual dimmer switch was removed from the PCB so I have no idea how it was activated..!? Anyways, shorting the location of where the switch should have been seems to have resolved the issue..

Hi BME, have you found a way to generate the licence codes?
