The main components of the Whirlwind E SnakeTM system are the E Snake Frame (ES3), E Snake 2 (ES2), and E Snake ControlTM software for managing the system. 

Each master unit (ES3 or ES2) consists of a hardware frame and motherboard that can be configured with input and output cards. Each card is capable of processing eight channels of audio. An ES3 can accept up to 4 input and output cards. Therefore, each ES3 is capable of simultaneously processing 32 inputs and 32 outputs.

ES2 can accept any two I/O cards and therefore process up to 16 inputs, 16 outputs or 8 of each. Multiple frames can be used to increase the capacity to literally HUNDREDS of channels if required.
