What do you expect the jack to be supported by? The PCB? I think there's still very good reason for using nuts as physical attachment points to provide support. Secondly, I also believe that in terms of shielding and immunity, having a metal jack and jack nut with properly masked chassis (or lock washer of sorts) is far superior to plastic jacks. I'm especially concerned about it in this day and age of GSM.
I certainly agree with you though, that metal or plastic jacks provide very little insight into the quality of the overall mechanical design. There are always price points and manufacturing constraints to deal with.

I am not going to write a tutorial on packaging and there are folks much better than I at that game, but better 1/4" jacks have screw bosses in them so they can be screwed down to the PCB. Even lower labor approaches involve solid bosses that nest into holes in the PCB to strain relief the forces from insertion/removal cycles. The fastest way to fatigue and trash a solder connection is to make it structural. Likewise if you have tens of 1/4" jacks in a PCB you need to resist the temptation to use that for fastening, although I suspect many smaller low cost (disposable) products do that (who me?  ) .
What exactly do you expect the metal barrel on a 1/4" jack to shield, the ground lead? With modern powder coating and metal treatments getting a proper ground even with metal nuts isn't insured. Good quality plastic jacks can even have special piercing ground contacts to cut into the panel chassis and make a decent quality ground connection. This is often adequate for shielding, not for high current safety ground bonding.
I will concede that I have used a metal barrel 1/4" jack on a low end fixed installation product (something like a 2W or 5W amp and I think I used a high current speaker jack)) for safety ground bonding and it passed agency testing, but that was a very small, very sharp pencil product, and not IMO best practice.
If you're a customer tho' of course you're right.

... there are (three?) expansion slots by the master section that let you plug in external inputs (like CAT-5 from a digital snake) and then you bypass the console's pres and use your alternate input by pressing that recessed switch.

Wow! Thanks.

I've been mixing on Yamaha digital consoles (01V, DM1K, DM2K) for a few years now and I love them for what they do. Despite that I still end up wondering every now and then if anybody at Yamaha ever spends any time at live gigs. The Yamaha consoles get the job done, but sometimes you really have to work pretty hard to get them to do what you want. The boys at APB have obviously been taking notes and I am very impressed with their understanding of what it takes to get the job done.
To be fair, I haven't got much time on the PM family so it is probable that my occasional sour grapes are just because of the particular consoles I can afford to use.
I wonder what a console that implemented the functionality of a Spectra-T console using a digital console's inners would cost? Could you implement this in digital for the something close to the price APB is asking for these? Add some dynamics (compressor/gate) to each channel while you are at it and that would be just about a perfect console.
In reply to the poster complaining about there only being one master fader, I hate multiple master faders. I often end up wasting a VCA or fader group just to make sure my master levels move in lockstep with each other.
Good job of understanding your market APB.
Phil
That's "newbiesque" to my friends.

Sorry, had to break into JR and Fred's "discussion" of metal and plastic jacks. Just to be clear, we use metal bushing jacks with metal nuts on the Spectra in all locations that call for Sleeve=Chassis. The jacks have pointy barbs at the base of the bushing that dig into the metalwork when the nuts are tightened to make a solid electrical connection.
For the XLRs, we use the type that provide a Pin-1 to Chassis connection at the mounting screw. Again, these have a small barb at the mounting locations to insure good chassis contact.
I think that most Pro gear these days would use these same components- the connector manufacturers have been quite good at responding to the audio industry's requests for better "grounding".
Thanks,
JP

Glad to see this console getting out there. Saw one at the SE Systems trade show. Very nice looking console. I wish it had been out when we were shopping. Has some nice features for HOW. The stereo channels have a special feature for handling split track cd's for tracks performances.
Who knows, we might have bought the APB instead of the Verona had it been out........

Lastly, thank you Mac for pointing out the lack of subgroups. I knew it did not have subgroups but until this moment I didn't think of the impacts of my style of mixing as I was focusing more in the VCA realm. Without subgroups how could I insert processing over a select group of channels?
As always thanks to all who help sharpen my knowledge and give me a different perspective.
Greatfull,

Grayson,
I beleive that the inputs can be routed to an AUX out, then to main outs, allowing you to insert processing! AUX on a fader is similar to a group.

I didn't mean to portray, nor do I consider, the lack of "groups" as a shortcoming, or disadvantage. In some ways it is an advantage. Like most higher end digital consoles, the use of groups and auxes becomes blurred. Those consoles, and the Dynasonics consoles, replace that paradigm with one where all mix buses can have variable level. If you need to process a group, you do it on one of the 10 variable mix buses. This is how a Midas XL3 works, it is how a Heritage 3000 works, and I assume an XL4 as well. Where the H3000 and many of the digital consoles differ is that it is possible to make the aux sends be fixed gain. The XL3 and I think the XL4 follow the same method as Dynasonics.

The XL4 has dedicated fixed gain subgroups in addition to variable auxes. The XL3 was the first large frame console that I'm aware of that eliminated fixed groups and replaced them with a variable buses only.

So the "get through it" kicked in and ended up running that side 20db hotter than the other. ... Now try and do that on a single fader console quickly.

You could always reach over to the graph or the DBX120s and balance the level there.
Edit: Did I say dbx 120. Oops. I meant dbx 160. The mono compressor frequently used in pairs on the L,R outputs.
