Subject: 1. Can someone recommend an audio interface for a 24-channel speaker ring? From: Lorenzo Picinali <LPicinali@xxxxxxxx> Date: Thu, 20 Mar 2014 08:18:48 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hello! I'd suggest the following: -SSL Alpha Link MADI AX with MADI Xtreme 64. This comprises a MADI PCI interface and a 2-units rack with 24 analogue channels I/O and a set of other digital connections (MADI, ADAT, etc.). -Focusrite Rednet. You should purchase the Rednet PCIe card, then you can buy the rack units...for 24 channels you can buy one Rednet 1 and one Rednet 2. -Another option would be to get any MADI PCI interface (or also ADAT, but in this case you'll need at least 3 lightpipes for the output channels), then DA converters (Behringer does some 8-16 channels cheap ones, otherwise Aphex, Lynx...). Otherwise...probably try to find a shop which still has a stock of MOTU 24i/o...I'm sure you can find some around!! I hope it helps!
