 The following tutorial will explain you how the hardware is setup and a quick introduction to the software and possible ways that you could expand the capacity of the multi channel sound-card and system.
-=== Types of Multi Channel Audio ===

+== Types of Multi Channel Audio ==
 There are three different types of speakers arrangements: first the most common one the stereophonic sound or two channel audio, surround sound or more than two channels and ambisonics or full sphere surround sound.

 In this tutorial we only are going to cover briefly the surround sound arrangement.
-=== Surround Sound ===
+== Surround Sound ==
 "Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (center, [front] left, and [front] right) originating only from the listener's forward arc.
-Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers." taken from wikipedia.

 The other connections are for digital and analog inputs and outputs such as MIDI, ADAT, SPDIF and WORDclock, this are different forms to connect other hardware and manipulate it inside the mixer, giving you the capacity to use up to 52 channels.

-In a Surround system or multi channel system like this one is it possible to use Ambisonics for Max Msp or Pure data to transform the arrangement of speakers into a spatial sphere system in this case with panning modes could be posible, for that you will need and ambisonics extension for max msp that you could download going to this [https://www.zhdk.ch/index.php?id=icst_ambisonicsexternals site] all the documentation is inside the max objects, or for pure data go [http://puredata.info/Members/ricky/grambilib here] or take a look on this other library for Pd [http://www.mshparisnord.fr/hoalibrary/en/downloads/puredata/ HoaLibrary].
