On a standard CAT-5 cable between two adjacent
machines I can get four (mono) channels at 48 KHz,
but trying to set channels 4 just results in a (very

I'm designing a mid-size (8 to 12-ch) ambisonics setup, using small active
near-field studio monitors such as Fostex PM04, Focal CMS40, BM-5A...(the
exact model will depend on the funding I'll get for this project).
