"i was wondering if a blumlein stereo configuration (2 figure 8's at 90 deg)
can be matrixed into L,R,LS,RS?"

I'd also be real curious to hear a report from anyone who has played around
with decoding blumlein recordings into surround.....in theory, this should
be entirely possible.  Although the math would be probably be different and
more complicated than described (maybe not, I'm not an expert on this by any
means), there should be a way to add and subtract the channels so that the
out of phase information is placed in the rear channels, where it belongs.
I've always been curious about this myself, but have never had any
recordings produced by this microphone technique to run through my
old-school quad decoders.  You can most certainly get the correct
mathematical result by editing software, but an old SQ or QS quad decoder
(or any quad / surround synthesizer) should also be able to perform
extraction of the out of phase material in the recording and place it in the
rear channels (DPLII might work, too).  The advantages of this surround
technique are that there's probably plenty of recordings already out there
that were recorded with a blumlein technique (the important thing here is
that the out of phase information is present in the recording), the surround
sound can be derived upon playback and regular two channel media can be
used, and it's by definition already compatible with regular stereo playback
equipment (just like SQ and QS were / are).  The disadvantage is that very
few microphones offer a figure-8 pattern (the AKG 414 is probably the most
well-known), and they're all expensive.....but I do remember seeing a
website somewhere that had instructions for building a DIY microphone with a
figure-8 pattern, it used two condenser capsules and an op-amp summing
circuit for each microphone......also, good decoding equipment is expensive
and hard to come by these days (anybody have a Tate II kicking around that
they wanna sell me?).....

Yours Truly,

The Arc Angels (Double Trouble W/Charlie Sexton & Doyle Bramhall II)
are doing a few reunion gigs in February and I'm looking for someone who
might be able to tape the shows. Here are the dates:

2/4/05 - gypsy ballroom dallas
2/5/05 - mardi gras galveston
2/26/05 - stubb's BBQ, austin

Most likely they will not allow open taping so it'll have to be a
stealth job. If anyone can catch these shows, please drop me a line. Thanks!

Ken

Hello, I haven't been able to access the BTAT lately. Does anyone know 
if Derek Trucks allows board feeds?
Thanks, Adam

What about the 3:1 rule?

28' away from a stage seems very far to me, particularly when it is
described as a "small club."  The whole situation sounds like a phase
nightmare to me.

Might I suggest moving the mics closer to the stage so that the distance to
the bar area  is three times the distance to the stage.  Since you have
cardioids, I would strongly suggest using a coincident X/Y pattern.  I have
recorded over 180 classical sessions (and one honky tonk bar band) with this
pattern and have never been disappointed.

I'm I fortunate owner of an used TASCAM DA 30 from few days.
Can I use DDS-90 with this unit?
I hope so because I have a lot of new DDS tape at Home.

Thank You.
Bye.

Colin,

I did the math, and my suspicions were correct.  You are entirely too far
away.

For a 110 degree setup, you would need to be about 8 feet off the stage, or
about 14 feet in a direct line from each stack.  Move closer.  Your setup
will be pointing at the stacks now, not the walls/bar.  Because you will be
closer you will eliminate reflections and chatty bar people.  The signal to
noise ratio (music to chatters) will be much more appropriate.  The strange
phase problems should go away too.

Good Luck

-M
