Re: [Sursound] analog planner
Somewhere I have MAG's original handwritten reports for the NRDC on (analog) soundfield controls, etc. I will see if I can find them tomorrow and post them. Might be of help to someone.

Re: [Sursound] analog planner
Finally, a Transcoder unit generating 2-channel UHJ only could be fed with stereo signals for front and rear stages with a stage width control on each. The Transcoder also has an B-Format input in an 5-pin XLR connector.

The schematics are in the Ambisonic Motherlode: http://decoy.iki.fi/dsound/ambisonic/motherlode/ Somewhere in there.. Eero Richard Elen kirjoitti 17.2.2020 klo 11:57: The Audio & Design Recording boxes that Geoff Barton designed were intended as (analogue) outboard units that could be patched into a conventional mixing console to generate (mainly) first-order (all there was) Ambisonic B-Format.

We were interested in developing a mixer to produce B-format from multitrack recordings, creating an artificial soundfield. It had 360-degree panning ability and radius-vector control on each. Two input channels used sine-cosine 360 degree potentiometers derived from scrapped electronics, probably radar consoles. Because we were unfunded and basically running on 'pocket money', the budget didn't allow for 4 sine-cosine pots so we designed and built two switchable pan-pots, initially 30-degree but planned for an eventual 15 degrees. ... ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
