[quote author="daArry"]EQ would be an option ye (been thinking of various ideas for that from NYD's passive to butta's Nemek) - but atm, just a basic mixer config is needed...[/quote]
Jakobs' Calrec is an option too....
Would a simple jfet buffer be adequate for the 2310 d'ya think btw?
For an output buffer? I would guess so, AFAIK anything that offers a high input impedance will prevent the THD from rising in the PGA. Jfets are high input Z(?) so I guess that would be a simple solution instead of a fully-blown opamp.....dunno.

Are you building MASTERING console or Dangerous stuff???
I opened one custom Crookwood. It is not mastering console
(for my snabby minds about mastering console)
.
Same cheap design.
Maybe once I will finish with 600 Ohm h-pad relay (gold teledyne
of course) attenators 0.3db/step, all routing on Leach aero stuff relays,
those freaky violet 0.1% resistors, teflon silver wire
and m-s trafos on huge 80% Ni & etc, I not just talkin'-
as well I have some resourses for this stuff.
For guys who _talking_ here about mastering consoles:
I heard the sound of some cheap mastering rooms and some what you call auudiophoolish setups. Last ones sometimes were much more clean
and suitable for mastering.
Cheap stuff for mastering room?
Well, another g1176. Working...[/quote]
Hey Igor!
Any pics from the inside of that Crookwood? - it it similar in design to the Dangerous stuff?
I'm not building anything like the above......that was just a "cheap-ish" suggestion for the sake of the discussion.
Mine is shaping up to be similar to your suggestion, yet not so esoteric.
All relay switched, passive process path, fully balanced, 4 inserts, 2k5 bridged-H process output trims on Greyhill rotary switches (10dB attenuation).
Relay switched passive monitor path, relay controlled (8 stage-cascaded) bridged-H level attenuator, 0 to -63.75dB in 0.25 steps. 0.5% metal films etc. Level memories/trims for source selection via PIC Micro. I'm thinking of ways to reduce the number of resistors in the signal path of the monitor attenuator. At the moment it is 8 per stage when fully balanced......I'm worried about noise,as thats 64 resistors in max attenuation. Any advice? Maybe O-attenuators instead, cutting it to 32?
Optional Forssell992/3 differential output stage for line driving unbalanced or balanced input power amps. Can be removed if running fully balanced room.
Headphone amp probably based around OPA627 etc and a pair of 5532/4 buffered meter outputs for VU etc. I hope I will get around to actually making this thing a reality in the next three months....no more talking! ;-)
It seems you get all the cool surplus out in israel!
