Wingman and 664, far too unreliable for me to use on a job--much too fussy.

A brief call to Yamaha support answered a few questions mentioned above. They do not view the DM series as replacements to the CL+QL or even the TF mixers and are still making all those. The DM3 is a different beast than a DM7, not just in # of inputs--they viewed the TFs as the next step up (in inputs etc) from the DM3. I asked for clarification on the number of channels to mix on the DM3, and they said that while you can mix and match input sources, 16+2 channels to mix is all you get, period.

So in this system what is the word clock master? What drives the TC generator (making TC for BR)?

CLs and QLs are much more expensive than DMs, even used. I don't think it will replace them, but will for sure replace TFs, at least among FOH folks. I'd be interested to know what is clocking the Dante feed for this mixer when it is using Dante for inputs. Is it something that is generating TC? How are you feeding the computer running BR? Dante? USB?

A very kind man and completely willing to give anyone the benefit of his long experience in production sound. At the end of his career as a PSM he really tried to get producers to see reason about wide-and-tight, all-lavs-all-the-time and stupidly noisey locations with the famous "Letter", mostly to no avail but it made him a hero to us soundies. As a vendor, as was said, he could not have been more supportive of the production sound community. RIP JC.

Wingman and 664=NG.

This would be a great test. My highly suspect anecdotal info seems to indicate less run time when the weather is super hot.

thanks!

Me too!

I did! Loved the sound!

Bruce B's custom mixer was lovingly made from the best parts and modules available back then, put together by someone with a very deep understanding of how dialog needed to be recorded given how movies were being made at the time. The Stella AMI was not a good mixer--pretty to look at, great size, not great sound, fragile and impossible to field service. There was one floating from recordist to recordist in my town for several years: people would buy it, try to use it and then give up when they listened closely to it or it broke (again).

I do a lot of live recording and even some live FOH style mixing in DAWs. You do have to manage your latency, for the live stuff I use mostly just the lightweight plugs that came with the DAW. Real plug-in work like NR, DeClick, heavy duty comps, big reverbs etc DO result in latency, which the DAW compensates for within itself. But you are right to be concerned about sync issues re: recording with cameras, even if you have your clocking very together (not at all a given with nearly all ADACs and digital mixers not operating on an accurate external clock). I'm sure you'll do your testing about this, I'd be very curious to hear what you find!

Yes but we managed our levels very well, as low as we could get to read, actually, but the content of that signal is really pernicious and audible as bleed at nearly any level. Below a decent level the readers, even with reshapers in line, could not reliably recover the TC well enough for it to be synced to/from in a fast-working telecine suite. That was the most expensive post work per-hour in those days, with all the adults in attendance in the suite, so panic over TC sync was always in the air and the blame fingers were always primed and ready (to point at the sound dept.). We also discovered that several popular brands/types of 1/4" tape stock would record TC in the center track that had just enough micro-dropouts that the TC would read fine on the recorder but not be recoverable in fast wind on an Otari MTR12 or Nagra T-Audio! I DON'T MISS THIS.

Bouke...TC DID bleed, sometimes at any level. It wasn't just a head stack issue, it was also a cable+connector+chassis+other electronics and routing issue as well. A great many things had to be done really well to avoid TC bleed, especially on the way IN to the recording device. We spent SO many hours chasing TC gremlins in audio post studios and on multicam video shoots.

In mixes at that time we could be running several analog machines in sync at once via LTC, including multiple VTRs, multitrack tape decks, 2 and 4 track tape decks as well as devices like CD players or outboard signal processors that were synced to or triggered by LTC. Making an analog machine run in dead sync to LTC required extremely sophisticated electro-mechanical designs, and the setting up of synchronizers that could talk to all these machines was a highly fraught task requiring a lot of time. LTC continued to be a major factor in audio post operations well into the early digital era, including DTRS tape decks and the early versions of ProTools, WaveFrame, Dyaxis, Sadie, etc etc. Facilities were often judged in part on how seamlessly all these devices could work together during a mix. In the Bay Area the patron saints and ascended masters of this were Bob Berke and Kelly Quan.

LTC on analog audio and video equipment was very much an "intended workflow", and was a pain in the ass. It did bleed, and when recorded the edges of the LTC word would get rounded off so recovering usable TC from an analog recording was a serious challenge. Since this TC was absolutely vital to the synchronization process a great deal of effort was put into the recording and playback of LTC on the machines of that time. I used to include instructions and suggestions for telecine operators syncing my 1/4" CTTC audio recordings, as well as my phone number in big letters on the outside of the tape box. It seemed that about 1 in 6 jobs would have some sort of issue with my tapes, usually (it would turn out) inflicted by the post-syncers on themselves. Since post-syncing usually occurred on the graveyard shift I got used to late-night or early AM phone calls, sometimes resulting in me having to go down to the post facility to coach the operator.

My tests and anecdotal experience with SM Lectros is pretty much what Louis got. The Eneloops are ok for low key kinds of jobs (interviews etc) with defined time frames, but for live shows w/o breaks or doco I went back to Lithium AAs. The cost is always an interesting conversation with the filmmakers....

The "scratch" track, AKA "reference track" is an audio feed sent to cameras from the sound dept so that A: playbacks with sound can happen immediately on-set (without syncing up the audio recordings) and B: so there is a reference for the editor to "eye-match" or auto-sync by audio waveform to in the audio syncing phase of post. A timecode-based autosync is perferred and has fewer issues, but many productions that do not use any form of timecode in the field rely on audio-match syncing (ie "Pluraleyes" and the Premiere onboard version of same) to sync their field audio with dailies picture. Thus having both a "scratch track" and providing timecode to a camera (from a TC generator that has been jam-synced to the TC generator in the audio recorder) is a very reliable method for making post syncing possible and straightforward.

Interesting idea. If Sony, Arri and RED adopt this then I guess it's what we'll do. If producers get sold on it as a new cheaper+more efficient workflow component then ditto. Until then this is pretty speculative, since this sort of change to established methods doesn't generally come from users like us, they are invented by the big manufacturers of gear and then sold to filmmakers through advertising and demos to their senior tech advisers. Standing by for more info!

As a side note, I think it is important to bill equipment by type or category. IE a client wants a wireless package with a certain number of channels, possibly for a certain price. It's my call what I give them--I don't work for people who specify brands and models of gear I will be operating.

It's worth it to ask if they want them? On many low-end small-cam jobs they don't understand or use TC as it would come from a Lockit etc..

well done

DT480. Just remembering them brings back the headaches they gave me.

Very tempted but never went for it. The size was very appealing for doco work.

Thanks for doing a real test. There is a long tradition of location soundies doing their own gear tests, no matter how "cowboy" they are so that they then really KNOW what their gear does. Well done.
