Ambisonic UHJ decoders
Here are corrections to the Gerzon "Multi-system Ambisonic Decoder"
published in Wireless World magazine, July and August, 1977.
Corrections to the phase shift circuits (Fig 1, pg 69, Aug 1977 and
m/l on pg 73 of same issue:
Reference Designator(s) m/l value correct value
C16 1nF 1nF
C17 1nF 1nF

R128 47k 115.655k
R127+R126 23.8k 50.941k
Notes:
1 - R142 on schematic incorrectly listed as R152 on material list
2 - Capacitors are chosen to be standard values most closely
matching
Gerzon values (except C14/15 which were typos)
3 - Resistors are either standard 1% (E96) values (where choice is
'arbitrary') or calculated ideal values to 5 or 6 digits of
precision.
4 - Capacitors should be selected to 1% tolerance
(or purchased that way)
5 - Resistors should be selected from nearest standard 1% value or
made of series/parallel combination to get closer to exact
value

Hi Giovanni,
Still hasn't gotten through - maybe you should email it direct to me
rather than through the sursound list...

I have it.
Give me a day to locate and scan it and I will send it to you.

Subject: [Sursound] Integrex decoder
Hi Folks,
I was looking out my documentation for the Integrex decoder and I
seem
to be missing the addendum sheet that I had covering the mods to change
one
of the mods (H or 45J, can't remember which) to UHJ, which wasn't in the
original Wireless World design. Anyone got a copy?
Dave
