I am new to audio hardware, especially hardware that interfaces with a computer.
I have built a 16 channel audio installation that runs off of 2 7.1 surround external sound cards. the four analog outs are connected via a mini-plug to rca cable to the stereo inputs on a car amp (four channel). Each channel runs through an amp to a speaker, so each channel operates completely independent of one another. This works fine and as expected (except on of the jacks on the cheap sound card has failed).
I am currently in the planning stages for building a 144 channel audio installation and am looking at several possibilities. One would be to use multiple boxes such as the MOTO 828mkII, but I can't tell from looking at the specs if the TRS outlets are mono or digital.
Since all I need is output, another route would be to use a PCI slot box and just run 13 sound blaster 7.1 surround cards from it.
Does anyone know of a good resource for gaining knowledge about how audio equipment interfaces with computers, and what one should look for at each point in the chain (computer, interface or soundcard,amplification, speaker)?
Does anyone want to share how they have built the hardware component of their sound installations?
