The Emulator IV (EIV) series of samplers was introduced in 1994. The new operating system used in the EIV was known as the Emulator Operating System or EOS, which was updated regularly by e-mu. Early EIV models with only 1MB of CPU Flash can be updated to 3.00b, while later models with 2MB or more can be updated to EOS 4.62 (non-Ultra) or EOS 4.7 (Ultra). There have been rumors that EOS 4.8 was in development and included support for USB transfers.

The Emulator IV was the first to be released, a rack sampler that came with 128 voices and memory expansion up to a then-massive 128MB.<ref>{{cite web|url=http://www.soundonsound.com/sos/1995_articles/apr95/emuemulator4.html|title=Emu Systems Emulator IV|work=Sound On Sound|date=April 1995|archive-url=https://web.archive.org/web/20150607005839/http://www.soundonsound.com/sos/1995_articles/apr95/emuemulator4.html|archive-date=7 June 2015}}</ref> Options included a multi-effects processor, additional output sockets and 32 MIDI channels.
