The Wheatstone Evolution Series (E-Series) Digital Audio Network System is comprised of several components interconnected via CAT links to achieve a very cost effective networked audio system. Each studio operates independently, yet can share all sources and mixes through the S-16 E-Series Wheatnet Switch—without traffic limitations, or machine control delays. The E-SAT accepts up to 16 discrete stereo analog or AES-3/SPDIF digital audio sources, and 16 stereo analog or digital outputs. Integral, high quality Sample Rate Converters (SRCs) on the digital inputs resolve sample rates up to 96kHz. The E-SAT may be fitted with up to 4 input cards, 4 output cards, and 2 logic cards. Hardware is described in the next chapter.

All audio input, output, and logic connections are made via DB-25 PCB-mounted connectors located on the rear of chassis. The factory supplied hand crimping tool is used for all DB-25 connections to and fromrnthe router (see instruction on page 1-16). There are also RJ-45 connectors for audio network and ethernet connections. Cage-to-cage network connections are made by UTP CAT5 crossover cables terminated with RJ-45 connectors.
